There is a factory now in sri lanka to make oxo-biodegradable polythene which can replace environmentally hazardous normal polythene. Plastic Packaging (Pvt) Ltd (PPCL) is the company which manufactures oxo – biodegradable. It can carry frozen food and heavy items. When you throw it away after using, it degrades fast and disappears within a short period under the heat, sunlight or in any other place where oxygen is available. Oxo-biodegradable polythene is water-proof, can be used in the rain and carry wet things such as ice cream, fish and meat.
The degradation time period of oxo-biodegradable bags can be shortened or lengthened depending on the percentage of additives, added to the chemical structure. However, according to the manufacturing process, oxo-biodegradable bags degrade within six to 12 months. Oxo-biodegradable bags are manufactured with a high quality additive called PDQ-H which is imported from the USA.
