Mark Duff
All right. Thanks, David, and good morning. I'm pleased to report we achieved a 35.6% increase in revenue and 112.7% increase in gross profit for the fourth quarter. We also generated positive EBITDA had a positive net income for both the fourth quarter and for the full year.
We achieved these results despite significant investment in both our internal bidding organization as well as in research and development. As a result of these investments, I truly believe 2024 is shaping up to be a transformative year for the company. And in 2025, we're poised for a major breakout. As I'm sure most of our investors are aware, we are preparing for several large initiatives that we expect will begin to materialize in the second half of this year and set the stage for unprecedented growth.
Let me begin by addressing some of our recent wins, and then we'll provide updates on some of the upcoming opportunities and specifically why we're so excited about the long-term outlook for the business. Within the services segment, we realized several new awards from the Buffalo Corp of Engineers; the U.S. Geological Survey, USDS; the U.S. Navy; and several commercial clients. We also developed teaming relationships for several large bid procurements.
In addition, our joint venture received an award of the Joint Research Council project through the European Union in the Inspra, Italy, facility, which represented a total of up to EUR50 million over the next seven years. Overall we finished the year with several strategic wins and accomplishments that we believe will support our long-term growth and help us fully diversify our revenue stream.
Within our treatment segment, with an increase in volume with steady improvement in waste receipts early in the quarter and this included increased waste shipments within the commercial sector, along with steady sales from our industrial waste programs. While we do not typically provide and do not plan to provide quarterly guidance, I believe that it is important to share a more detailed discussion of what we expect in 2024.
We consider this year to be a transitional year based on the business environment and the investments we have made over the past several years. This is what we believe will be an exciting 2025. Beginning in the fourth quarter of '23, we started facing certain headwinds that we believe were temporary, but will have an impact on the first half of this year.
First, as previously disclosed, during the fourth quarter of '23, we completed our two largest service projects at the Princeton Plasma Physics Lab and the McKee ship decommissioning project for the Navy. Both these projects were very successful with strong safety records, and we achieved our anticipated margins and outstanding client ratings throughout the project.
That said, with these two projects now complete, we have not yet secured all the replacement revenue in the services segment due to the timing of the awards and opportunities we're waiting on. The gap in work, which we anticipate will last about four months has resulted in challenges and weaknesses that will be reflected in our results in the first half of 2024.
In addition, due to the inability of Congress to pass a federal budget, the government has been operating under a continuing resolution, which has contributed to delays in procurements, project starts, and waste shipments, since government clients are holding back budgets due to the uncertainties and the potential of a shutdown of the last five months.
January is also a tough month with weather impacts, closing two of our facilities for a week and delays in project production in the field as well. That said, February and March have shown some positive trends in both segments.
As a result, the next few quarters will be weaker, and we've anticipated due to the timing of contracts as well as delays relating to the pass of 2024 federal budget. However, as things normalize, we remain confident in getting back to our -- in surpassing our business base goal of $25 million in revenues per quarter.
In addition, we anticipate that the 2024 budget approved last week will provide increased opportunity for Perma-Fix as the enacted budget reflects about a 9% increase over 2023 at the Department of Energy alone. As I mentioned earlier, we remain particularly optimistic about the second half of the year and could not be more excited about the outlook for the business in 2025, given the magnitude of the projects we're currently working towards.
As we've discussed previously, we are rapidly advancing several initiatives that we believe will significantly enhance our revenues and long term backlog beginning in the second half of '24 and potentially much more in '25. I'd like to briefly discuss each of these initiatives to provide our investors an overview of the vision for next year.
First, we're benefiting from an increased bidding opportunities within our services segment, including both the government and commercial sectors. We're positive we are positioned for large ongoing procurements within the DOE and the Navy as well other midsize procurement initiatives from both the DOD and EPA.
These large procurement opportunities include proposals to be submitted over the next few quarters. So we've been able to secure strong teaming relationships for potential awards anticipated throughout 2025 that would potentially represent substantial increases in sustainable revenue over the next 5 to 10 years.
Second, we're extremely well-positioned to provide waste treatment services. This is part to support the DOE's Hanford closure strategy, including the treatment of effluent from DFLAW facility once it commences vitrification operations, which should provide vitrification services to about 40% of the tank farm at Hanford.
In January '23, DOE signed a record of decision, a ROD, to treat the effluent waste streams from the DFLAW facilities to include our local Perma-Fix Northwest facility for at least the first 10 years of its operations. We remain optimistic about reports coming from DFLAW in regard to start-up of the smelters, the vitrification plant, and the supporting systems, which continues to progress towards hot commissioning in 2025.
As stated in several of the past quarterly calls, we're well positioned to treat all of the effluent waste from those operations as defined in the 2023 on a record decision by DOE, which estimates specifically this January, up to about 8,000 cubic yards of waste annually upon the hot startup of the vitrification plant. As I mentioned in the past, the volume of this waste would more than double the production of all of our plants combined on an annual basis.
Third, the DOE at Hanford has formally recognized the importance of grouting relative to the overall closures strategy as a preferred supplement to the current DOE strategy for vitrification of up to 57 million gallons of tank waste stored at Hanford. The Hanford System's Rev. 10 document published in January and developed over the past three years by DOE defines a new preferred scenario for the Hanford site closure. That specifically includes vitrification of DFLAW for the east side of the tank farms and the west side to be treated through commercial grouting technology.
The System' Rev. 10 is currently being implemented to include two new tank removal systems to be installed and operated in late '25 and early '26. One of these removal systems will be built, installed, and operated to support the DFLAW facility while the other one will be dedicated to removal of tank waste for shipment to commercial grouting facilities after disposal off-site. Both the specs for these removal systems include performance parameters of 3.5 million gallons per year for throughput for pulling waste out of those tanks.
Perma-Fix maintains and operates these our growing facilities today at the Perma-Fix Northwest facility, which is permitted and outfitted to safely and compliantly grout up to 30,000 gallons per month with the ability to expand that capacity to over 1 million gallons annually while dramatically reducing cost risks in schedule compared to the vitrification alone. It's important to note that our facilities at Perma-Fix Northwest offers the only local or regional object for grouting tank waste near the Hanford site and uses the rail to ship treated waste for off-site disposal.
This is a much safer option than shipping untreated tank waste by truck out of state for grouting and disposal, which is specifically designed as a higher risk in the need for documents, including the environmental assessment as well as the [weird] document developed by DOE. So when looking at both treatment of effluent from DFLAW and grouting, DOE is making significant progress in Hanford and the other plant locations in (technical difficulty) strategically well positioned technologies to provide increased value towards those objectives.
Fourth, we're expanding our waste treatment offering within the commercial and international markets including Europe, Mexico, and Canada. These opportunities will generate sustained receipts beginning in 2025, providing fine revenues estimated over $10 million annually, which we expect to begin to be realized in late '24. The award of the JRC program in Italy, coupled with our expanding international clients, represents continued growth opportunity based on the market for advanced permitted and efficient waste treatment to provide stable waste forms that minimize long-term storage costs.
The JRC project supports our expansion program in Europe, including existing IDIQ contracts held by Perma-Fix in the UK and the application of our treatment technologies in other European market. If we continue to invest in our facilities and capabilities, specifically, we're implementing several upgrade activities at our DSSI facility in Eastern Tennessee. That will include a multimillion dollar expansion project to allow a broader treatment of reactive waste for our clients, including advanced safety and security systems to address the growing inventory at several client location.
Additionally, we're investing at the in-source ordering technology to include fabrication of the second source or potentially a third to be deployed by the end of second quarter of '24.
Sixth, and finally, we've made important advances in new technology to treat PFAS contamination. While we look forward to full unveiling our technology and strategy in the coming months, I want to give you a glimpse into what we've been working on. For those of you unfamiliar with PFAS, which is an acronym, PFAS, which stands for polyfluoroalkyl substances, which are synthetic or chemical compound. The markets for the treatment and disposal of PFAS is exploding due to the hazards associated with these, what they call forever chemical.
Thousands of sites across the world have large inventories of chemicals. Not to mention all the sites within the PFAS contamination require remediation as well. Estimates for this market vary widely. However, the opportunity to provide services and treat PFAS contaminated waste for government as well as municipal and commercial clients is estimated to be or exceed over $10 billion over the next 10 years according to the Environmental Business Journal.
In fact, PFAS destruction represents one of the largest potential markets for environmental cleanup over the past several decades. Our new technology includes five patents that have been filed to support the complete destruction of PFAS with no off gas, no toxic effluent emissions. Perma-Fix co-founder, Dr. Lou Centofanti and this team of engineers and chemists have spent countless hours developing and validating this new technology.
While we know that there are many firms and pursue the PFAS remediation, we're confident that our complete destruction technology, coupled with our existing network of generators and clients will support rapid expansion of system to be deployed at each of our plants locations in 2025. We've already received PFAS from customers. And we recently completed bench scale testing of our new technology supported by independent verification, which demonstrated an undetectable presence of contaminants after treatment.
Our engineers recently completed design and the proof of concept system that will be tested later this month. It is actually being tested as we speak, followed by the fabrication phase for our prototype systems currently scheduled for testing and operation in the second quarter of 2024. We'll be spending the coming months conducting system optimization studies to maximize our destruction effectiveness while reducing operational costs before we launch our service into the market, at which point we expect to begin generating revenue later this year.
Given the low cost as well as the technological and environmental advantages of our new process, we're already witnessing significant interest from major potential customers as well as regulatory agency. Our estimate for revenues in '24 is approximately about $2 million at the end of the year. However, once in production, the base -- and based on discussions with our customers, we're hopeful we'll achieve multiples of this revenue in 2025 as have the ability to ramp up production rapidly with high-margin potential.
And one final note regarding PFAS to put the market opportunity in perspective, I'd like to quote Time Magazine, which headlined and I quote 3M's historic $10 billion forever chemical payout is just the tip of the PFAS iceberg. So market's very strong and very well documented.
So to wrap up, the investments we're undertaking the first six months of 2024 should position Perma-Fix for solid growth in the second half of the year and should position us very, very well in 2025. At the same time, we're making significant investments, as illustrated by the fact, R&D is up 67% in 2023 over last year across all projects.
We believe these and other investments will allow us to reap the rewards of years to come. Meanwhile, we remain focused on increasing backlog and productivity for reducing operating costs to maximize our margins in 2024. I'm very proud of our team that we've assembled, which now includes top-notch business development and sales team, members as well as experts from across the industry with expertise in chemistry, waste engineering, health physics, and field operations.
As a side note and from a macro perspective, 2024 is bringing greater attention to our industry as we were seeing increases in nuclear power throughout the new plant as well as SMR or small modular reactors, which with a renewed emphasis on long-term solutions for radioactive waste management. For the first half of 2024, looks to be below our performance objectives with a few temporary headwinds, we believe that we're well positioned after a second half of growth of the year with very high hopes for 2025. I can't emphasize this point enough, and we're more encouraged than ever by the long-term outlook for the business with a number of potentially company changing opportunities in the near-term horizon.
Okay. So on that note, I'll now turn over the call to Ben Naccarato, who will discuss our financial results in more detail. Ben?
Ben Naccarato
Thank you, Mark. I'll start with revenue. Our total revenue from continuing operations for the fourth quarter was $22.7 million compared to last year's fourth quarter of $16.8 million, an increase of $6 million or 35.6%. The revenue improvement, which was supported by both operating segments, came from our treatment segment increasing revenue by $1.6 million or 19%, and that came from increased volume and was offset by slightly lower average pricing. Our services segment increased by $4.3 million or 53%. And this came from increased scope from one of our larger projects and the startup of several smaller projects.
For the year ended 2023, our revenue finished at $89.7 million compared to $70.6 million last year. As with the fourth quarter, both our operating segments had substantial increases with the treatment segment increasing by $10.1 million or 30%, and the services segment increasing by $9 million or 24%. Again, consistent with the fourth quarter, these improvements were volume related in the treatment segment and the result of increased project work in the service segment.
Turning to our gross profit for the quarter, our gross profit was $4.3 million compared to $2 million in 2022. The treatment segment gross profit improved by $564,000 from improved revenue and lower fixed facility expenses. This was offset by higher variable costs related to revenue mix. In the service segment, gross profit improved by $1.7 million from higher revenue and improved margin on our project work, and this was slightly offset by higher indirect payroll related expenses.
For the year ended 2023, our gross profit was $16.4 million compared to $9.6 million in 2022. Both our operating segments' gross profit improved, with treatment segment improving by $1.6 million, and that's from higher revenue, offset by higher variable costs and increased facility expenses. The service segment gross profit increased by $5.1 million from higher revenue and improved margin on its projects offset by higher indirect payroll-related expenses.
Our SG&A for the fourth quarter was $4 million compared to $3.6 million in the fourth quarter last year. While our SG&A for the full year finished at $15 million compared to $14.7 million last year. SG&A in the quarter were higher, primarily as a result of higher employee incentive expenses booked in the quarter. Similar to the quarter, SG&A expenses were up for the year from employee incentive expenses and other payroll related expenses offset by lower audit, legal, and other consulting expenses.
Our net income for the quarter was $81,000 compared to last year's net loss of $1.7 million. For the year ended December 31, net income was $485,000 compared to a net loss of $3.8 million in the prior year.
Our basic and diluted net income per share for the quarter was $0.01 compared to a loss per share of $0.13 in the prior year. Income per share for the year ended December 31, 2023, was $0.04 a share compared to a loss per share of $0.29 in the prior year.
Adjusted EBITDA for continuing operations for the quarter as defined in our this morning's press release was $434,000 compared to a loss of $1 million last year. For the year ended 2023, adjusted EBITDA was $3.3 million compared to a loss of $3.3 million in 2022.
Turning to the balance sheet, our cash on the balance sheet was $7.5 million compared to $1.9 million at the end of 2022, reflecting improved cash from operations and the reload of our term loan by $2.5 million in July of '23. Our unbilled receivables were up $2.4 million, reflecting increased year-over-year revenue -- December revenue, primarily in the services segment.
Our current liabilities were up $3.2 million from the timing of payments and increased expenditures, particularly in the services segment. At December 31, our waste treatment backlog was $8.7 million, plus an additional $2 million of unearned revenue for a total of $10.7 million, which is up from $9.2 million at the end of '22 and $9.6 million at September.
Total debt at the yearend was $2.9 million, excluding our debt issuance costs, which is mostly owed to PNC.
Next, I'll discuss cash flow activity for '23. Our cash provided by continuing operations was $6.7 million. Our cash used in our discontinued operation was $597,000. Cash used for investing of continuing operations was $1.7 million, all related to cap spending. Cash provided from financing was $1.7 million, which represents proceeds from the reload of our term loan of $2.5 million and proceeds from various option warrant exercises of approximately $300,000, offset by our monthly payments to the term and capital loans of $709,000 and payments related to finance lease liabilities and other debt of approximately $364,000.
With that, operator, I'll turn call over to questions.
Question and Answer Session
Operator
(Operator Instructions) Howard Brous, Wellington Shields.
Howard Brous
Thank you. First of all, Mark and Lou, congratulations on the beginning of a great turnaround. There was an article in Barron's this past Saturday that indicated that the markets for PFAS is about $100 billion, not $10 billion. You missed a comma there, Mark.
Mark Duff
Okay. I thought I said $100 billion.
Howard Brous
$10 billion. Let me start with the first question about opportunity. We know about OSMS. Are there other very large opportunities like OSMS in the foreseeable future? If you can be a little granular, we'd depreciate assets. That's my first question.
Mark Duff
Sure. Howard, I appreciate your question. Yeah, we are always sensitive to discussing ongoing procurements, but we are participating in the rebid of the West Valley project in New York, which has been submitted. So we're on a team for that. That's about a $3 billion project over 10 years. We're teaming partner, so we're not prime on that. That's anticipated to be awarded in the Q4, Q1 timeframe. And also, we tend to have a very good team that we intend to participate on the Enterprise decommissioning project. Enterprise is an aircraft carrier that the Navy will be decommissioning, and we'd expect that to be awarded in the proposal. We expect the proposal to go in later this summer and award in May of '25. So those are just a couple of the big bid we're playing three major roles in.
We are still waiting on OSMS. They have gone out to, what they call, final proposal revisions, where they asked bidders interesting questions and provide some feedback. So we are in that process and it's very difficult to project when they plan to award that but word on the street and speculation is they expect to award that little bit later this summer, with the transition to be completed at the end of this fiscal -- government fiscal year, which is end of September.
So there are still no word on the award for that, yeah. There's a couple of other we're negotiating teams on right now, but that's generally where we are on the big bid.
Howard Brous
Okay, thank you. Let me focus on the DOE document that you referred to earlier. Can you confirm that they've adopted scenario number two?
Mark Duff
Yeah, we're referring to the Hanford System's document Rev. 10, they call, which is a 400-page document. It includes two primary scenarios for their closure strategy, and that's a pretty dramatic change for DOE over the last three years. They put that every three years.
And the first scenario is specifically what they've been moving towards for the last 10 or 15 years, which is vitrification of all of the tanks and in some form. And (inaudible) get the other floor running and then they were going to build a new or a second floor type of plant treat the other half. What they've done is they've abandoned that capital project.
In the scenario two, where they basically are saying I have the tanks. We'll go to via floor plan the other half of the tank -- of all the tanks will go towards grouting, but specifically commercial grouting. In other words, DOE does not, at this point, intend to build a grouting plant, but they plan to outsource it.
They have not -- I mean, there's not an official document that says they're implementing scenario two, but they have publicly -- DOE have publicly stated that they are adapting scenario two. In fact, they are procuring the waste treatment removal systems, I mentioned, as the first step. So there is -- are to be awarded here in the next couple of quarters and are to be implemented for pulling waste out of the tanks, as I mentioned in late '25, '26 time frame. And this design bases are about 7 million gallons a year we pulled out of tanks with both of those combined. Half gone to the [other floor]. Half gone to grouting program.
Howard Brous
That said, if you subtract a high-level waste, which is 68 million gallons, you're left with 48 million gallons. And in the document you're referring to, the comments strongly made is they would split it, as you indicated, which ultimately means 24 million gallons of vitrification and 24 million gallons for the grouting. That's my understanding. And two, therefore, the rod that was talked about in January of last year, talked about 10 years, when effectively at 1 million gallons a year of vitrification, you're talking about 20, 25 years were generational long. Is that a fair comment?
Mark Duff
Yeah. Howard, there's a couple of things missing from that comment. Yes, you're correct about 25 million gallons in total would be a good estimate. But keep in mind that when you pull a gallon of waste out of a tank, you're typically adding two to three gallons to slurry it out to get it out because it's largely dry, or best case, peanut butter kind of consistency. So you got to add water to it and so you expand those gallons significantly as you're pulling it out.
But generally, you're right. The duration is quite long. It’s, I mentioned, 7 million gallons a year. That's the capacity they're pulling out. They don't have the capacity to treat that much. So I'm assuming that 7 million gallons a year as designed capacity would not be really attainable. That would be something less than that when you consider downtime and changing out the resin columns and those kinds of things that have to happen in an outage quarterly. So it'll be a little bit less than that generated, but quite a bit actually. But it's a significant amount of waste over a significant amount of time that will span multiple careers of people.
Howard Brous
So last comment to put a bow on all of this is specifically in this document, talk about half grouting and half vitrified. And the half to be grouted is to be shipped to Perma-Fix, all of it. And then once it's grouted, shipped to, I think, it's Andrews, Texas, WCS. That's my understanding after reading document. It's a long document.
Mark Duff
Yeah, it is. Maybe a bold prediction, it's -- we have a contract, obviously, for the -- to support the ride after DFLAW and the grouting of the tank farms, which is obviously a second component of the overall strategy. It hasn't been defined specifically for us that they're trying to find other folks have to compete with us, which is obviously in the best interest of the taxpayer.
Again, as I've mentioned, and we've talked many times, we are the only regional opportunity to do that. And we have agreements with the local unions to use their services as well. We're excited about that. And the alternative, as we've mentioned before, is to ship the untreated waste via tanker truck to off-site facilities that are not in the region. It does take a long time to get a permit from the state and 10 years plus as estimated. So we feel like we're in a really good position to provide the lowest risk approach as well as the most efficient approach. And we're looking at advanced technologies for the grouting process and designing for the most efficient means of grouting that large volume as we expand our plant, as the volume increases as (inaudible) plant over the year.
So we feel like we're in a great position. That seems like a no-brainer, but we've going to meet their objectives as well. But we're pretty confident we'll get the majority of that waste as it starts to be generated from the tank farms.
Howard Brous
One of the issues is shipping through [Malheur] tribe sacred lands and they said, no. My understanding based on the treaties that they have, the United States government that supersedes the ICC and the ability to ship it over their territory. So shipping it to Clive, Utah, I don't see that based on the evidence and the comments, I don't see that happening. What about Andrews, Texas?
Mark Duff
Yes, the Malheur tribes have been very vocal about shipping untreated tank waste through the reservation, which is required largely to ship a tanker off of the reservation and goes out through Oregon, and they continue to -- the tribe continues to be vocal about that. That's a political issue to deal; we have to address. But it certainly makes it very difficult and difficult for DOE to use as an option, which we've gotten good support and letters have been written supporting on our facility to do the grouting, ship, and solid waste form by rail, which have been supported. It's much more stable and safer way. And if you do the accident scenarios for that number of trucks, the statistics are a lot different than by rail. So we're pretty confident that that comment you just made will assist in recognizing the value that Perma-Fix is providing to DOE and with our local facility.
Howard Brous
Last question, and again I'll rejoin the queue. When you talked about 2025 and PFAS, what kind of multiple, if you're doing a couple of million dollars this year, how do you foresee this developing in 2025? And do you have the capacity to do it?
Mark Duff
Well, that's a really tough question, Howard.
Howard Brous
All right. Sorry.
Mark Duff
yeah, it's okay. I'm not prepared to give a lot of detail. I knew we'd get these questions about what does it really mean to us in '25. It's really tough to nail it down because we don't know our throughput yet. We are just finishing treating, what they call, firefighting foam, or AFFF in drum quantities right now in our pilot plant. And we're nailing down the parameters for the unit. In other words, how much it can -- how fast it can go, with what the mixtures need to be to optimize the system.
And as I mentioned, we are getting very meaningful results. In other words, we're meeting and demonstrating that we're meeting despite any regulatory limit that's been proposed out there. So in other words, we're receiving -- we're seeing total destruction of PFAS, where most of our competitors have a waste stream coming out either an effluent or air emissions or some other type of effluent. So we're very excited about that.
We don't know what that really is going to mean to us next year. As I mentioned, our goal is to develop a plan for treating this AFFF at each of our locations. AFFF, we view as the lowest-hanging fruit of the market. People have hundreds and thousands of drums of AFFF stored their facilities all across the country and literally all across Europe. And basically every Air Force base and airport has trained with firefighting foam which has been one of the bigger causes of the contamination.
So we're focused on those first. We're still trying to define what the market will bear in regard to a cost where we can charge per gallon on this versus what our costs are. So it's really difficult for me to address that with a specific number, Howard. I will say this as we get -- we're going to be having press releases come out in the coming months and defining this more and more and more as we get these results. It's moving very, very quickly and we have a lot of people working on it.
And it's all been -- we've been checking all the boxes for the parameters we meet up to this point. So we're excited about it. And every day that goes by, we're more and more confident that it will really hit the ground hard running when we get to our final test.
Howard Brous
Congratulations, senior management team. Thank you.
Operator
Walter Schenker, MAZ.
Walter Schenker
Thank you. Just one more point on the key facet, that's how you pronounce and people mentioned it was nice a Barron's article. So we can understand more about the market. Simply, because I like simply, what you have developed is a methodology to burn, to destroy the firefighting foam as the lowest-hanging fruit. Is that like the kindergarten way of looking at it?
Mark Duff
No, not really, Walter. We are we are not burning it. Burning it has been largely banned, in other words, incineration by DOE and DOD. And the reason they banned it was because of the potential for putting PFAS in the air and the amount -- the difficulty in controlling that. Our approach is using chemistry. And with a strong potential and we're developing this now and I'll let Lou jump in if he's got much to add something here, that we can recycle some of the chemicals we're using in our system. That's kind of phase two of our technology demonstration. That would literally pretty much eliminate all the effluent concerns that other technologies have. So the heat will certainly and pressure will certainly accelerate the chemical reactions we need to occur, but there's no off gas, which is what you'd get if you burned it.
Lou, is there anything you want to add to that?
Louis Centofanti
Yes, it's a very simple process, basically done in a sealed container. Take the liquids, dump in our special materials, sit for a couple hours with some temperature and everything's gone. Everything we've screened it on, every floor carbon we screened it on has, the system destroys it even Teflon. So we are very excited about it. It has lots of application -- potential applications, like Mark has said, the number one application initially that we see the low-hanging fruit is the liquids, either from old materials sitting out there or some of the separation processes that are starting to be used for groundwater, cleanup of that. So we see a very large potential market in several different areas. The first one being liquids, and then we'll look to -- we're continuing to look at all the other potential applications of the system. We see a lot of application -- potential applications.
Walter Schenker
Thanks. By the way, hi, Lou.
Louis Centofanti
Hey, Walter. How are you?
Walter Schenker
And therefore, since I was [willing] the first time, this market is again potentially billions of dollars or tens of billions of dollars. And Perma-Fix is a very small company and it's nice to do a couple of millions or even tens of millions, but that's an almost insignificant against billions. Therefore, it is possible or likely on a longer-term basis that you could license this one of the very large players.
Louis Centofanti
We've kept every option open on how we grow this. The first real obvious since we have facilities that are licensed and permitted and all of this. The liquids one is a very simple starting point for us where we can learn more about the technology. But we are looking at all the above. There's a lot of on-site work that could be -- this process could be used that. And we've talked to a variety of larger companies that might be interested in working with us, especially with the on-site market. So yes, you're exact -- we're keeping all options open at the moment for how do we apply this and what route we take.
Operator
Brian Russo, Sidoti.
Brian Russo
Yeah, hi. Just wanted to follow up on the Rev. 10 document and grouting, what are the next steps for DOE or any milestones that we should look out for? Not in terms of Perma-Fix's role because you have a very strong position but just timing on when this scenario could accelerate.
Mark Duff
Thanks for your question, Brian. What it comes down to is my initial answer to that is that the tank removal systems have to be procured and installed. And we met with a firm just yesterday that is one of the players in that market and they are in competition now. I think the submittals for those proposals is in within days of now. I'm not sure when exactly, but it's very, very soon.
And then they'll make an award. And I'm speculating on exactly the date, but in the next several months, likely in our Q3, and then the milestones for fabrication, construction, and implementation of those removal systems will occur over the next year. So the milestones that used to track that is really when DOE will be capable of removing the waste.
And the interesting part is the one removal system will feed the DFLAW, I mentioned. There's an infrastructure, a piping on the east side tank farms that will be used to feed the DFLAW plant. On the West side tank farms, which is just about 50% as I mentioned, there's no infrastructure. So we pretty much move the system from tank to tank to tank and then start pumping into totes because there's no piping infrastructure. And those totes will be delivered to the treatment facility.
So it's a lot simpler, more flexible, and can move very rapidly. So I see that the primary milestones associated with that tank removal system that we mentioned.
Brian Russo
Okay, great. And can you just elaborate on the European expansion strategy? You mentioned the JRC earlier and the 10 million of waste shipments that could ramp up thinking later in 2024. Any more developments on the of the UK Westinghouse facility?
Mark Duff
We are still working towards that and working on the parameters of those agreements as well as considering other options, in addition to that. We're putting the agreements together with several other countries in Central Europe that also include dramatically large backlogs of waste in inventory. The one thing I've learned in the last two years that basically every power plant over there has enormous storage building of waste and they would sit now waiting for a treatment facility or for a large long-term storage facility to be developed. And there's a big market and reducing those volumes back through incineration and significant size reduction that it would save lots of money. In other words, their storage facilities are jammed full.
We're working with individual firms doing partnering with others to build a backlog, and we intend to ship those waste to Perma-Fix Northwest in the interim and working right now with Westinghouse and other organizations over there to meet that need and thinking outside the box on how to do that.
Certainly, the technology we have at our Northwest facility is very applicable and there's a lot of interest from other companies are in Europe now that are managing those waste for their commercial clients. And I've had numerous meetings in the last two months trying to address that need.
So it is a very expanding market and we continue to put business together for other countries, as I mentioned before, Croatia, Slovenia, and Norway, and throughout the UK. So it's a really growing market. And again, I have a tough time defining what that really means to us in long-term revenue. But I do as several of our agreements will be mature by Q4, and we'll start seeing shipments increase that in '25.
Brian Russo
Yeah, great. And then lastly, could you share with us what the services backlog looks like as of December?
Mark Duff
Yes, about (multiple speakers) about $14 million.
Operator
(Operator Instructions) Ross Taylor, ARS Investment.
Ross Taylor
Thank you. First, congratulations on surprisingly good quarter. I honestly didn't think you guys would be able to, given all the back or the headwinds from the government and the like, would be able to put together a quarter like this this quarter. Great job doing that. A couple of things. With this PFAS situation, is your process protected by patents or other intellectual property?
Mark Duff
We do have patents plans for now. Go ahead, Lou. I'm sorry. Go ahead.
Louis Centofanti
Yeah, I'm just going to say we have patents pending, as Mark said earlier, and we expect to be filing quite a few more covering the different applications as we further develop the data for the patents. So we think they are. We're in the process there. They're pending at the moment. And they cover the US and Europe. The applications are all set to date in stone for both the US and Europe. And then we're looking at what to do in Asia.
Ross Taylor
Okay. And when you pursue these opportunities in that area, are you seeing this as Perma-Fix is going to people or I mean, example, like are you going to the DOD, which has obviously a huge problem in this area and trying to basically get a contract with them? Or are you JV-ing in this area? How do you see going to market with it from Perma-Fix--specific standpoint ?
Louis Centofanti
As Mark said initially, the focus is on liquids, whether they be out-of-date products or coming out of fire foam systems today or being generated by some of the separation processes that are presently being used on drinking water and other wastewater. As we expand, we're somewhat open. There's been (inaudible) that the facilities give us a tremendous advantage. We already see liquids --- PFAS liquids coming through our facilities. So it's a natural that we now have a destruction process to destroy them and then --
Ross Taylor
Okay. And so as you said, that's where you're sitting with that. And I'm just trying to get an idea what the economics at this point end up being shared economics? Or is this something that you actually believe that early stages you have been able to go out? Your first few wins will be Perma-Fix unique wind, where you'll be catching the whole other or will someone else be the prime in this. Has the government and other major players actually already started to pursue the type to cures? So are you looking to --?
Louis Centofanti
So we're hoping to have demonstrations for -- we're already in the process of discussing with DOE a demonstration project for some of their waste. So the same with DOD. So that's all going on right now. And but again, mostly on the liquids side. The next phase will be focusing on the on-site opportunities that exist out there, and we're already starting to explore that with --
Mark Duff
(multiple speakers) we have some agreements in place. They are not formal JV agreements, but we're working with several companies as partnering that have access or support clients with large inventories. I mean the process we're going through right now is we're receiving samples from different clients to run through our pilot and bench scale tests to show them how well it works.
The first step is receiving samples from different people, different -- that have large backlogs of inventory and partnering with firms that we work with regularly that have clients with have big backlogs. So that's kind of where how we're hitting the ground running fast is building that base of inventory that we can -- that will get us going.
Ross Taylor
Does this process require you to have significant capital expenditures? Is it the type of situation where you would need to build something at each facility? Or is it the type of approach that allows you to effectively almost create a mobile or somewhat-mobile capability that you can move from location to location? Or would you be putting it on your own locations and having the materials come to you?
Mark Duff
Lou? Go ahead, Lou.
Louis Centofanti
Yeah. Initially, it's the latter. It's easy to put a facility and it's not expensive. You're basically talking about tanks, reactor tanks, and the pressurized tanks. So step one is do it ourselves at our facilities, gain knowledge on the process, and at the same time, looking at how it can be applied to other applications
Ross Taylor
Okay. You talked about Europe, you talked about first -- what you see going on, what the potential is out of Germany? I think they've shut down or will have shut down all their new capacity, when I would think that that would might be the biggest market available in Germany or in Europe or Central Europe. Can you just -- am I right in that read? And when we look at the European or Central European opportunity, are these where you're going to have a unique JV in each country? Either is there someone in Europe, like the leading player in this, and your work with them to pursue these opportunities? How does much again like your go-to-market approach in Europe?
Mark Duff
Yeah. We're working, in fact, at the conferences we can finish working with several different entities in Europe that are here participated in the conference. There isn't a central organization. And you're correct, Germany is pretty much the largest near-term market as their decommissioning 17 reactors that are all in different phases of decommissioning. And they all are generating waste as they decommission as well as having significant volumes of waste in storage.
And Germany is building a very large long-term storage facility and a former iron mine in Germany that has a very specific acceptance criteria that they have to meet to get their waste into that facility. So what we're offering two different clients in Germany is the ability to treat that waste, reduce the volume, i.e., reducing the storage footprint they need to get it in, and making it stable to meet that criteria.
So we're in the process of working where there is several organizations involved and there's numerous waste streams that we wouldn't deal with. And there's a lot that we would. So we're working through that right now.
In regard to JV, that be more like partnerships and agreements and unlike the Westinghouse situation, which is a JV. But these are all part of the offering we have through Westinghouse and through other organizations as well, depending on what the waste stream looks like. And it's really kind of unfolding at this point, but all pointing towards early '25 to get rolling.
Ross Taylor
Okay. And just real quick one last. Just going back over and looking at DFLAW, what's the correlation between revenues for you and operations for the vitrification plant? How quickly do you start to see cash flow from that once they start to get it up? Are they currently operating at a low level and are you seeing some process or some materials come through that? And as it works, I think they have two melters. So I thought would be they start one melter and then they start the second melter at a point after that. Is that how it's going to play?
Mark Duff
Yeah, they're going to have the cold commissioning right now, which is -- as opposed to hot commissioning. Hot commissioning will use some radioactive surrogates to begin to run through the system. Right now, just kind of give you schedule, schedule is not defined very well by DOE. They have a very hard and fast agreement. It's really well defined to have the plant operational -- fully operational -- I should now take it back. Operational, which means they have to be vitrifying waste by August of '25.
DOE intends to beat that. They've said that publicly numerous times, and that -- at that point in time, it will be generating depending on how many melters are going way to 8,000 yards, I mentioned. However, we fully intend that as they go through hot commissioning and start adding radioactive surrogates to the class that they'll generate waste on that as well.
So we anticipate that to begin earlier in '25 as they do the demonstration of the technology, and the whole process overall, it will start generating smaller amounts of waste in the scheme of things.
But you're right. We see a ramping up through the year. And by the end of '25, certainly we would expect both melters would be operating and be at the annualized rate of the [SM], which is the 8,000 yards -- actually, cubic meters.
Ross Taylor
Okay. So by the end of '25, you would think you'd be at a run rate. There was some talk, I believe, in the Seattle publication that you might see something -- they might see something come out of that in late '24. Is that just a pipe dream?
Mark Duff
I did see that too. And I know where it's getting these numbers from. But it's very difficult. DOE is intentionally avoids committing these things because it's like investing. If you gave the comment, you can be held accountable. You can hope for your performance.
But the bottom line is that they're working very well. They're very excited about meeting the milestones as they are meeting with the melters. They're actually working as anticipated. But [DFLAW is] to go before they get to full operations as it goes through a lot of readiness reviews like any nuclear plant starting up, which takes a lot of effort and is very difficult.
Having said that, Ross, I really believe that there are -- anything before the first quarter of '25 would be shocking to me. But they might be able to get started. It's hard to say.
Ross Taylor
Okay, and I'll leave with, once again, congratulations and the PFAS opportunity, out of the blue, but really exciting. And just generally, as you said, it looks like we're setting up for a really not only exciting, but quite profitable '25. So the road kind of longer than people hoped for, but it looks like you're well on your way on it. Thank you.
Mark Duff
Yeah, we were very nervous about launching the PFAS status until we got through our bench scale and had it independent -- our result independently validated by a third party. And so really this is exciting time for us to be able to mention it.
Ross Taylor
Yeah, thank you.
Operator
