Thank you so much, and good morning, everyone. Well, the heading for our third quarter report is Resilient Performance with Strong Cash Generation. Let's start by looking on the key highlights for Q3 2020. Stable sales volume despite challenging markets. Successfully accomplished maintenance shutdowns, we will talk more about that. Accelerated delivery of cost and efficiency program. Strong operating cash flow generation, and Recyclable Flow Wrap product launched. Just very briefly, figures for Q3: net sales SEK 5.561 billion, adjusted EBITDA of SEK 570 million, which gives a return on capital employed of 3%. Ivar will go into the details of the figures in just a couple of minutes.
What I would like to start with today is just to also point at the fact that we are a very innovative company, and we have, during the quarter, actually introduced our new product, the Recyclable Flow Wrap, which we're very proud of. It's a paper-based packaging solution, which actually enables a shift from plastic materials, wrapping materials, to paper products that are both recyclable and based on renewable raw material. This has been a joint project together with Syntegon and their Swiss R&D center. Based on primary fibers, renewable and biodegradable, as I said, suitable for confectionery and bakery products. These packaging solutions have excellent barrier properties with medium to high barrier requirement papers.
The good thing with this product is that it can run on existing flow wrapping machines after installation of an upgrade, rather limited investment, and it can run with no speed restriction, which is quite unique for a paper. Here we have all of a sudden a paper product that definitely can compete with plastics for wrapping of candies and chocolates, et cetera. I think this is a product that we have big expectations around going forward. Looking more on our running business, let's have a look on the business status and outlook. If we see the different segments we're active in, food and drink, we've seen during the third quarter, rather stable business trend there, and the outlook for Q4 remains stable. No big change.
There are sectors, sub-segments within food and drink, of course, that some of them are doing better and some of them less good. Medical and hygiene. Here, we actually have seen during the third quarter a more challenging trend than before. This we see as directly related to the fact that COVID-19 now takes all the resources of the segment in terms of hospital care, et cetera, and this has a negative effect on many of our products. Consumer and luxury. There, we see a stable development during the quarter, and we don't see a big change going forward. Does not mean it's on a good level, but it's at least stable. Industrial, very much the same development.
Overall, I would say if we look on our entire business portfolio, the trend during Q3 has been fairly stable, with some small upsides and some downsides in terms of mainly some pricing pressure on certain grades, such as liner and fluting, and white sack and some of the MG, MF assortment. The big thing for us has been, and remains, of course, KM7. Let's have a look on KM7 and Q3. Overall, we see very positive progress. The progress continues. We had maintenance shutdown or stop in September, which was very important for us. There were certain modifications we had identified a need of doing, and these were completed successfully during the quarter. All key activities went as planned, and we executed upgrades that were required. This will enable both a higher speed and a higher stability on the machine going forward.
I'm also happy to say that we've seen a very positive customer feedback now on the material that we have delivered to customers from KM7, and this is in particular valid, I would say, for the coated grades, where we're very pleased right now. It means that we can produce today all the products that we intended on the board machine within our set specifications, which of course, is very important for us going forward. The negative EBITDA impact is decreasing. In Q3, we could see a negative impact of SEK 80 million, which means that for 2020, the estimate for the full year is going to come out around SEK 450 million. The trend is positive. Going to the next slide. Capturing the value of KM7. Our focus has now moved from, let's say, the technical aspects of the ramp-up into commercialization.
We're focusing fully now on commercialization. We can produce all the products that we want to produce on the machine. We have, however, seen that the combination of COVID-19-related market effects have slowed down the commercial ramp-up somewhat. This, of course, you can see in our figures. We can see that our customers' priorities have shifted during the COVID-19 period. They have limited evaluation ability. Let's say that their ability to evaluate new suppliers and new qualities is reduced during this COVID-19 period, which perhaps is not so surprising. We've also seen somewhat weaker market for container board, more price-wise than volume-wise. For KM7, we do expect to reach EBITDA breakeven during 2021. Then the journey, of course, continues towards reaching the full potential of KM7.
This, we intend to reach by commercializing more volumes in financially attractive segments, scale, and flexibility in our three board production sites, which is an important factor. With KM7 now, we can optimize much more what grade, what product we produce on different machines. We can really focus on producing the most suitable grades for every single machine. This will, of course, increase our efficiency going forward. We will also see now going forward that we will get out lower fixed costs at the Gruvön Mill due to efficiencies that we can accomplish by the fact that we've closed down a lot or a number of smaller machines. We now run one more modern machine, and after introducing and, let's say, educating staff and so on, we can pick out some of those costs.
Let's have a look on what we see as perhaps the most important parameter going forward when it comes to KM7, and that's driving the right mix, which is instrumental for the KM7 contribution. I think what we need to be aware of is it's very easy to talk about volumes, but there is much more to the contribution than volumes. What we have seen, and I think if you look on these graphs here, is number one, to the bottom left, initially when we started the machine, you can see that there was quite a high degree or percentage of waste and secondary grades that were produced, and the prime product output was lower. Step by step now, we have increased the prime output and reduced second grade and waste.
Second grade is basically now down to zero level. The vast chunk of what we produce now is prime grade. This is important because basically when we get second-grade quality and even more so with waste, and especially in a market such as the one we've seen right now with COVID-19, it's very difficult to sell these grades and get any contribution. Just the fact that we're now running a higher and higher share of prime grade does increase our contribution in itself. If we look on the top left graph, material produced, what you can start to see there also is that exactly as we have communicated earlier on, we started up with uncoated material and some second-grade production.
Now since a number of months back, you can see a trend, the bottom right there with the dark green, that coated material is month by month now increasing. This is the material that is supplied to our customers. A combination of improvements of the development of the mix and eliminating waste and second grade is what's going to drive the positive trend for KM7. Naturally, in combination with some volume increases as well, but contribution per ton is very, very important here. With that, I think I'll ask Ivar to have a look on and dig a bit deeper into the financials for the quarter.
Yes. Thank you, Lennart, and good morning. We start with some comments on the net sales bridge, as Lennart already mentioned, it's 5% down versus a year ago. 2% of that is currency related, we're talking organic net sales of -3%. On volume, we are flat. Despite some positive mix, it's basically the market relating pricing that pulls down the number to -3%. We'll come to the product area figures in a second. Like the story has been over the past quarters, it's within product area paper and solutions, we will see the biggest net sales decline. You follow on into the EBITDA bridge, we've already communicated this as part of our Q2 report. This has been a heavy impact of this maintenance phasing.
We still have a negative pricing component, which is close to 4% of net sales, and that's obviously quite significant. From there on, we are able to offset most of this negative impact through a series of positive and mitigating actions. We have a sizable help from raw materials and consumables, where the biggest factor here is from the lower fiber cost. Our cost and efficiency program keeps delivering, and we add another SEK 95 million of structural savings. We have a volume mix help of SEK 65 million. We have a currency help of SEK 20 million , which is mainly a result of the positive hedging result, which leaves us in the end with SEK 570 million EBITDA. That's 11% down versus a year ago.
Please keep in mind that this has been in a quarter with significant higher maintenance phasing and quite tough market conditions. If you move into a bit more detail on the commercial result, starting then with product area board. Product area board is down 4%, where currency is roughly half of that, we're talking an organic result of - 2%. This is weaker top-line performance from board versus what we've seen over the past quarters, and I'll come back to some of the items impacting this because it's a little bit different perspective per segment. Liquid packaging board is down 3% and has had a tough quarter. It's partly impacted by the maintenance phasing in Gävle. We've seen an inventory adjustment in some of our customers. We also had some startup challenges after a maintenance stop, in particular in Gävle, which has been reflecting our availability.
For carton board, it's coming in slightly negative, but there's a couple of nuances in that number that I'd like to convey. Volume growth is still very strong and in line what we've seen over the past quarter. It's +12% versus a year ago. That means that we've had a relatively low net sales per ton in this quarter, and that's mainly related to the first commercial carton board volume coming out of KM7. There's no doubt that also going forward, we expect that net sales per ton number from carton board from KM7 to come in line with our category average. container board, or that will be the fluting and liner, is growing nicely, in particular with the liner volume growth. We also have volume growth on fluting. In total, we've had 24% volume growth in container board versus a year ago.
There has been a market pricing correction in container board from the beginning of July. It leaves us with an EBITDA margin of 9%, clearly then impacted by maintenance phasing. If you would have taken that out, we would actually have been an EBITDA growth of 3%. Moving on to product area paper. We are down 12% on net sales, currency being 3%, we're talking organically -9%. Sales volume is down 3%, a lot of that is down to pulp. If you look at more of the commercial grading and looking at paper excluding pulp, volume is up by 4% versus a year ago, which is encouraging. sack is down 7%, it's clearly a better performance for brown sack versus white sack.
In fact, if you look at the volume for brown sack, we've had double-digit growth versus a year ago and also growth versus Q2. This trend is very encouraging. The situation for white sack continues to be challenging. For kraft paper, we're down -6% versus a year ago. A bit like the situation is for sack, the kraft paper volume is performing much better. It's slightly up versus a year ago. In particular, if you look within the kraft paper grades, it's the white MG which is still having the most difficult conditions. All the grades are doing clearly better. In terms of the profitability for product area paper, we're holding the profitability flat versus a year ago, which is a result and also very strong cost and efficiency mitigating actions that we've taken over the year. Moving into solutions.
We're down 19% decline, it's very much a reflection of still tough market conditions. Most of our business in Managed Packaging still sits with the North American brand owners, and they are heavily impacted by the COVID-19. Although we do see one step towards normalized level in Q3, and the performance in Q3 has been stronger versus what we saw in Q2. Also for solution, we've been able to protect profitability well through a series of cost and efficiency mitigating actions. If we move on, Lennart mentioned already this a bit in the beginning, but our cost and efficiency program is performing well. We've added another sizable contribution now in Q3, SEK 95 million, meaning that the year to date has delivered SEK 235 million.
There's no doubt that we look at now an accelerated delivery versus than the ingoing target for the year, which was 250, and we foresee now to land 2020 of SEK 300 million plus. We also with this now, and based on three quarters of a pretty good confident run, we raised the ambition level of the program by SEK 50 million to SEK 650 million. Same time dimension as we talked before, that all of this should be in place as a run rate of Q4 when we come to 2021. If you move into next page, talk a little bit about our input and raw material cost, starting with the pulpwood and the fiber. Decreased slightly in Q3, roughly SEK 20 million help versus Q2.
If we look forward a bit, in particular for Q4, we see that there will be a further slight help for that cost item, partly then of a full quarter impact of the price reduction that we saw during Q3 as of August. Besides that, there's not really any items that we expect. We should have an help in the area of SEK 15 million Q4 versus Q3, as situation looks right now. In terms of caustic soda and part looking into chemicals, we had a SEK 50 million cost increase in Q3. A lot of this is actually based on the pricing that we saw during Q2, and then there's a certain timeline before it hits our P&L. In Q3, we have seen that the pricing have come down at least slightly on caustic soda.
There's been a bit offsetting items. We do expect a slight help in the area of SEK 5 million in Q4 versus then Q3. For energy, versus Q2, spot prices increased by almost 50%. It's been extremely volatile over the last couple of months, which I'm sure some of you already have read and seen yourself. If you just looked at the spot prices, that would be in SEK 44 million hurt, and we've been able to get rid of half of that through our hedging position. We had in the area of a SEK 20 million hurt versus Q2. What we expect in Q4, it's very tough to say. The situation is extremely volatile. We expect close to flat development for the energy versus what we have seen in Q3. Moving on to a cash flow situation.
We have had a very strong operating cash flow, and it's a combination of several things. We've already talked about the underlying EBITDA result. If you look at some of the other items worth highlighting, we've had a very good working capital improvement, and this is mainly, if you look at that change versus a year ago, it's partly because of payable change post on the KM7 program. That's impacting more of what we understand from the base last year. For this year, we also had some receivable good performance by very close monitoring and some slight inventory adjustments. From the net financial items, the amount there is mainly due to tax payment phasing or timing. The operating investment reflecting a new normalized level versus then a very much higher number last year, which is clearly linked to the ramp-up or the payments of the KM7.
That means that we are looking now at a slightly lower net debt versus EBITDA ratio versus Q2. It's down to 2.3%. I know that the last bullet points on this slide is a lot of interest. We do expect a decision regarding the Frövi, the recovery boiler in Q1 2021, we do not have any more comment at this stage. It's getting closer to a decision, there's not really much we want to say more on that regard today. With those closing remarks, I'm just handing it over to Lennart.
Thank you. Trying to summarize the third quarter then, as we've said now a couple of times, resilient performance, stable volumes, and a strong cash generation. We have also successfully accomplished maintenance shutdowns. However, as Ivar was into, we did have, I have to say, some start-up delays after these maintenance shutdowns. Partly, I would say this is a result of all the precautions and careful planning we had to do in order to safeguard the health and safety of our employees and external contractors in the situation we have now with COVID-19, and that has made things a bit more complicated. We have also accelerated our delivery on the cost and efficiency program.
I think this here we now raised the ambition to SEK 650 million, the total result, and we have launched our Recyclable Flow Wrap, a new paper that we have big expectations on, where we have seen already now significant interest from major brand owners who have successfully tested these products. Q4 outlook. Well, we have to say that uncertainty remains. The visibility is limited considering COVID-19 and what is happening now, not least here in Europe. We do expect raw material costs to decline slightly during the quarter. There were a number of maintenance stops also planned for the fourth quarter. Frövi and Skärblacka, there we have actually done these, and those two mills are up running again now. Pietarsaari in Finland, they are doing their shutdown right now and expect to start up again on, I think it's the 27th of October.
Everything there seems to be going according to plan. We also continue the ramp-up of KM7, and we're building this now, which I'm extremely happy to say, on a very positive customer feedback that we're getting on the qualities that we are supplying. With that, I think we basically have taken you through. Next time it will be Christoph Michalski who presents, and I'm very pleased to say that. With that, I think we're done and open for questions, Lena.
Ladies and gentlemen, if you have a question, please press zero, one on your telephone keypad now. That is zero, one to register for a question. I remind you that if you want to ask a question, please press zero, one on your telephone keypad now. There are no questions at this time. Please go ahead, speakers.
Okay, no questions this time. We conclude this conference call. Thank you for participating, and welcome back when we report our year-end results the 29th of January. Thank you and goodbye
