Opis:
Over 350 million tons of conventional plastics are currently produced from petroleum per year and this amount is expected to rise exponentially in the near future. Proper disposal of these products has caused a great problem for the waste management industry and as a result, there is a significant negative impact on the environment. As a matter of fact, in order to reduce the environmental impact of plastics, some products obtained from agriculture (like starch) are used as polymer blend with synthetic plastics. This study shows that Manihot esculenta can be blended with polyethylene to form a partially degradable polymer. The processing conditions and sample formulations are shown to significantly affect the structure of the polymer which has a concomitant effect upon the degradation ratio as well as the degradation rate. Six samples were produced by varying composition of the blend between Low-density Polyethylene and Manihot esculenta using glycerol and water as plasticiser. These samples were buried in soil and the degradation ratios and rates were studied within a period of 28 days. The results showed that these produced biopolymers are environmentally compatible and bio-degradable. The rate of biodegradation in soil of these biopolymer samples varied largely. The polymer blend with 80% LDPE (20 CaS) by weight had the most regular weight loss over the period of the study. Under the conditions the study was carried out, polymer blend 20 CaS also had the steadiest rate of degradation. Hence, 80% LDPE (wt.%) blended with Manihot esculenta starch is the optimal ratio with regard to the degradability of biopolymer in sandy-loam soil.
