The disappearance of PE

A very enterprising Indian company, together with its global partners, appears to have solved the environmental problems caused by the scrap of waste PE plastic bags, can liners and various plastic packaging. This is a unique technology that can completely degrade various PE products in waste. The degradation process has already begun in the extrusion stage. At this stage, a small amount of additive that promotes degradation is added to the material. According to the different application requirements of the product, a special balancing mechanism is adopted to ensure sufficient service life. If a garbage bag has a useful life of 18 months before losing strength, the bread bag may only take six months. Degradation can also be accelerated by other factors such as sunlight, heat, and tears.

The special properties of plastics: strength, fastness and durability are all due to their high molecular weight and chemical bonding between atoms. PE discarded plastic bags, although very popular and useful, are still considered to be detrimental to the environment. If a material is degraded to a certain degree under certain environmental conditions for a certain period of time, it is said to be degradable. Degradation of PE composed of carbon and hydrogen atoms is due to the reduction in molecular weight, loss of strength, and durability due to breakage between carbon atoms. As this process continues, the molecular weight of the product is reduced from 2.5 million Daltons to 4000 Daltons, resulting in rapid decomposition of the material under various conditions.

The degradation process begins with the processing, at which stage the material is added with a readily decomposable additive. Once degradation begins, it will continue. Gradual degradation results in the release of trace amounts of carbon dioxide and water (the amount of which is equivalent to the amount of human release at each breath) and some biomass. In sunlight, photodegradation will also occur, allowing the film to completely decompose into carbon dioxide, water and biomass. Because the additive is neither water soluble nor toxic in a degraded and non-degraded state, there will be no leachate contamination. Degradable products will remain stable under appropriate storage conditions. The product has a shelf life that can be affected by environmental factors such as heat, sunlight, oxygen, and time. Degradable products can be produced in different specifications according to the demand.

The supplier has performed an aging and OIT test on the product at the RAPRA Technology Centre in the United Kingdom. The test data has been amended to include the requirements for different products that have been in direct contact with food in 2002/72/EC. The biodegradable PE is fully tested to the EU 2003/72/EC standard by RAPRA. Ecotoxicity testing is also necessary and has been carried out by the Belgian OWS composting experimenter. The same additives were also tested at the Bombay Textile Research Association and were waiting for other tests such as colony pure culture experiments (G21), compost testing, municipal sewage sludge testing, and natural landfill testing.

The test results prove that the material is degradable (if relevant information can be provided), and it will not leave behind toxic by-products, saving space, can provide a solution to global environmental friendliness, and finally solve the problem due to polyethylene in the family Problems caused by the use of.
