This article on MSNBC offers hope for the green movement in its long battle to eliminate the use of plastics (or at least greatly reduce it). Plastics are derived from petroleum and, as we all know, are not biodegradable. They are currently polluting our oceans, filling up our landfills, and overflowing from almost every household. But this new material is made from lignon, which is produced as a side effect of making paper. It is being called liquid wood, and it appears to be as versatile as plastic, with one key difference – it is biodegradable. The German researchers developing it say it can be used for everything from toys to car parts.
