摘要：Disposal of plastic waste is a serious problem, because plastics accumulate in the environment and cause significant pollution due to their degradability. Therefore, the main objective of this research was to reach the biodegradable plastics industry as alternatives to non-biodegradable plastics. And the existence of such biodegradable plastic must contribute in reducing the emission of harmful greenhouse gases and keeps the environment clean, and reduces the cost for pollution from the accumulation of plastic waste. Algae was used as a raw material for the production of bio-plastics because of its unique properties such as it grows rapidly and in large quantities at a low cost and grows in a variety of water environments throughout the year, which means that there is no risk in the difficulty of securing the raw materials needed for the production of bio-plastics The study concluded that the tested samples partially decomposed in fresh and alkaline water during a period of 26 days, which means a high dependence on algae to the production of bio plastics as an environmentally friendly industry..
