Abstract
The use of synthetic polymer in the industries and household packaging for various purposes has increased, however, it possesses environmental challenge due to its nondegradability. This research therefore focused on the production of a biodegradable plastic by blending various composition of poly vinyl alcohol (PVA), additives and
cassava starch. The product produced (plastic) were extruded, analysed and tested for biodegradability under natural conditions. The results obtained were compared with the
conventional polymer. The density of the produced plastic was 0.83 Kg/m3, melting temperature was 200oC and its water adsorption rate was 1.3% per day. The tensile
strength was 23.63N/mm2 compared to 10.86N/mm2 and 8.29N/mm2 for polyethene and paper respectively. The results showed excellent retention of physical, thermal,
structural and mechanical property required in plastics. Thus, indicating the possibility of universal application of Nigeria cassava starch as a source of biodegradable agent in
plastic films production
