MANUFACTURING OF BIODEGRADABLE PLASTIC FROM BIOMASS

Abstract

Plastic is a daily used material which cause serious environmental problems as their disposal methods are dangerous to both land and water. Plastics made of bio-based sources could be seen as a promising alternative to the conventional plastics as it tends to degrade safely and rapidly and hence helps in the safe environment management.

In this research, Potatoes peels together with acetic acid and glycerol were chosen as raw materials for the production of the biodegradable plastic. The objective of this research is finding the suitable raw material amounts and operating conditions which will give the nearest specifications to the conventional plastics.

Low reaction and drying temperatures were found to be the most suitable for physical appearance of the plastic. On the other hand, high acid amounts were recommended for rapid degradation and lower water absorption. Moreover, using high amounts of starch have enhanced the degradation properties and strength of the samples.
