A Review: Plastics Waste Biodegradation Using Plastics-Degrading Bacteria

Plastic is a synthetic polymer that is widely used in almost every field of life. The massive use of this synthetic polymer has led to the accumulation of this polymer in the environment thus polluting the environment. The general techniques in preventing plastic waste as landfill, incineration, recycling are considered less effective as they release some hazardous materials to the environment. Thus, the appropriate technique is needed to overcome this problem. Biodegradation is an enzymatic degradation involving some microorganisms including bacteria. This technique can be used to prevent the plastic waste problem. Plastic waste biodegradation occurred through several steps, including biodeterioration, depolymerization, and assimilation. Within this process, bacteria will secrete many enzymes that will degrade and convert plastic polymers into microbial biomass and gases. Thus, this process has fewer even no side effect.
