Does this make the building material much more flammable?
It doesn't say whether this is using the treatment that removes all the lignite from the wood, leaving only cellulose, and compressing that. That was supposed to provide a sort of wood product that was as strong as steel, but lighter.

A building whose structural members are lighter doesn't need as much support, which may then be lighter, in a virtuous cycle.

Another material that has this property is titanium, which is surprisingly cheap, apparently smelted as a sort of afterthought to manufacture of the actually important product, titanium dioxide for white paint. Scrap titanium sells for less than scrap steel.

I have estimated that a SpaceX Starship (the "can" on top with the fins) after the engines are stripped off, would be worth maybe $40,000 as scrap steel. I had initially thought that the "thrust puck", probably of titanium, would be particularly valuable, but was completely wrong.
