A new company is putting a green spin on children's classic toys. Toy sets for making tea, cooking and playing in the sand will be made from bioplastic that uses corn and other natural materials as a base, according to Green Toys. Green Toys is launching the new line of toys at the San Francisco International Gift Fair this week. Per the company, the sustainable materials are provided by Cereplast, and the biodegradable colorants are from PolyOne. Pricing for the toys has not been announced.

Biomaterials are being used extensively in car interiors and packaging, and tots' toys is a natural fit since they inevitable chew on and often ingest parts from the toys. Rising prices for petroleum products will make sustainable products more cost competitive, but then again, ethanol is making corn more costly as well.
