Very intriguing. When will this be available on the US market? Anyone we can write letters to to move this forward?
The carbon issue is complicated by the fact that one can easily make choices that will impact overall energy inputs. When we built our first plant, capital costs were a concern. So, we used natural gas to produce steam. In the future wood waste could be used. In fact, I think I could design a process that could have zero fossil fuel inputs (into the actual process). It all comes down to capital costs.
This didn't quite answer the net carbon balance question; also please add in the carbon footprint of acetic anhydride to the LCA, if it already isn't there.
When will this be available on the US market?
We have been putting some into the US market, but I don't have details on whether it is going to be available for purchase. You can e-mail Starla (her e-mail is in the essay) and she knows all of those things.

That's because the carbon balance issue is very complicated. Is the wood being sourced next door, or halfway around the world? Where is it being sold? Are you making your own anhydride, or are you shipping it halfway around the world? Lots of questions like that make the carbon balance question entirely dependent on the specific situation.
However, we sequester more carbon away than we use to make the product. Also, note on the anhydride that it gets chemically locked into the wood, and so is sequestered away as well. The other thing to point out on the anhydride is that we can make it ourselves, and if the economics dictated we could make it from wood waste.
We are in the process of having some more LCAs done to cover specific usages for Accoya. Hopefully this information will be widely available.

How is your feedstock made now? Do you have any efforts underway at this time to determine the economic feasibility of making it from wood waste?
Any other beneficial products or feedstocks that you can recapture from your waste stream?
Will, we don't currently make anhydride from waste as the economics of doing so aren't good. I am working on multiple energy reduction projects however, and that is in the stack.
