Wait what? "lignin underutilised", (used)"only in low-value applications"? If by low value applications they mean individual house heating then perhaps. Could those factories that make wood products and currently dispose of their waste wood(sawdust etc) by selling it to pellet makers make much more by selling it for aviation fuel? I seriously doubt it.
The most recently I bought wood pellets I paid about ~$30/GJ aviation fuel(jet a) now appears to be around ~$56/GJ. It is more, but not orders of magnitude more. Add to this the cost of chemicals, reactors, disposal of byproducts and I doubt this new use will provide more profit.
- ZeroGravitas 4y agoI believe there is some kind of black liquid that is a waste product of paper production. I've read a few ideas for reusing this. I think traditionally it's been burnt to power the paper processes. https://en.m.wikipedia.org/wiki/Black_liquor https://en.m.wikipedia.org/wiki/Black_liquor > In the United States, paper companies have consumed nearly all of the black liquor they produce since the 1990s.[6] As a result, the forest products industry has become one of the United States' leading generators of carbon-neutral renewable energy, producing approximately 28.5 terawatt hours of electricity annually. So, assuming those land based processes can be substituted for renewables energy, that frees this up to be used in transport. (And yes this also applies to wood burnt in electricity generation, CHP and home heating. Burning stuff is inefficient, costly and polluting, we should be doing less of it whenever we can. Get a heat pump and some insulation).
