A new process to recycle wood not only means you can build something with it again, but it will have more strength than steel.
tells us about a process to recycle wood, but with a twist: the process not only means you can build something with it again, but it will have more strength than steel.
The good news is that you don’t need full pieces of wood to build things. Small pieces, broken wood, and even sawdust or pulp can still be treated to create this new material. This can happen because the donor material doesn’t technically continue to be wood. A solvent called dimethylacetamide, used with lithium chloride, can break down the cell walls, releasing lignin, a glue-like chemical in the wood.
“We get a mechanical strength that supersedes the strength of the original material,” one researcher told. “It works because we use the inherent properties of cellulose, which is a material that binds together very strongly by something called hydrogen bonding.”
