Bio-based polyurethane foam

What is it about?

Lignin is the main component of corn stalk enzymatic hydrolysis residue (EHR). The lignin is isolated from the EHR by alkaline sodium method. And then the separated ligin was used as bio-based polyol replacing partial petroleum-based polyether polyol to prepare eco-friendly polyurethane foams (BPU).

Why is it important?

This present paper reports an environmentally friendly, potential and promising method for complete utilization of lignin from EHR in consideration of their abundant supply to enhance the mechanical properties greatly of BPU foams.
