An environmentally-friendly preparation of plant material from pine could serve as a substitute for petroleum-based chemicals in polyurethane foams.

Researchers developed flexible, bio-based polyurethane foam using lignin extracted from pine. This eco-friendly alternative replaces 20% of petroleum-based chemicals and matches conventional foam in ...

Like regular polyurethane foam, the bio-based foam was equally robust and pliable. The journal ACS Sustainable Chemistry and Engineering published the study. Ziqi Yu (Postdoc), Isaac Nartey Oduro (PhD ...
