Abstract: This paper mainly introduced the research and development of polyurethane foams, based on starch, rosin, plant oil, lignin and cellulose both at home and abroad. The polyurethane foams properties such as biodegradability could be improved by substitution of petrochemical materials with biomass. It also could reduce production cost and raise market competitive power.

Key words: biomass, polyurethane foams, progress, biodegradability
