ich is manufactured from both sugar beet pulp and a biodegradable polymer called polylactic acid, or PLA, using a twin screw extruder. PLA is a commercially available polymer derived from the sugars in corn, sugar beet, sugarcane, switchgrass, and other plants, all of which are renewable feedstocks.

The researchers showed that up to 50% sugar beet pulp
