Plastics are being manufactured on a regular basis, therefore their necessity in our life has also increased. It has wide range of applications in every sector be it a part of food packaging, building materials, or consumer products etc., due to its excellent physical and chemical properties such as durability, plasticity, transparency, resistant to corrosion, light in weight and low in cost. Around 100 million tons of plastic is produced worldwide and its demand in India reached upto height of about 8 million tons as per in the year 2006-2007. There are certain problems related to conventional methods employed for the degradation of synthetic plastics as they have a detrimental side effects like burning of plastics release huge amount toxic substances polluting air, water, soil and land. This review looks at the current research on the discovery of new synthetic plastic degrading enzymes as an alternative to conventional methods. Studies on the structures of synthetic degrading enzymes isolated from non-engineered or engineered microorganism or plant source, can help in modifying their effectiveness or mechanism of action so as to completely degrade the synthetic plastics, from long polymeric chains into small monomeric units, which have inaccessible ester or amide bonds to hydrolytic cleavages.
