The way of Biodegradable Plastic is Still Long Away

Which kind of bag should be used for rubbish? Is the garbage bags bought in the supermarket safe enough? The environmental chemical expert Dong Jin Shi said in an interview that, many people use plastic bags quite casually. Are aware of a shopping bag the luggage which can't degradable. This not only wastes resources but also brings potential threat to the condition. Have learned that, at present, the total involving Chinese large and smaller portions of plastic packaging companies is more than 60000, but most production of garbage bags can't deterioration. Dong Jinshi, said residents in our country according to the daily use trash bags in 1 billion, each bag weighs 10 grams, so should be used throughout every season more than 2000, 10000 tons of oil. Although garbage sorting processing are usually introduced in some places, but the reality is garbage is put into different bins, but were swept away by the 'car' outfit, to handle and no classification. People use not degradable garbage bags will have a harm to the workspace. Reduction high polymer material co., LTD., Shanghai created a biodegradable plastic bags, national plastic products quality supervision and inspection center after 122 days of testing, found that the degradation rate can reach 62%, the rest temporary objects into tiny particles within the soil and the air is harmless. This form of biodegradable plastic bag adopts the patent technology of the united states and the European Union, the starch and non-biodegradable crushing into nanoscale after through special equipment, put in a variety of materials for physical degradation of resin combination epigenetic output. By the national products quality supervision and test center tests, with degradation of resin production, 62% can 'change' for the water and carbon dioxide. Test report, according to the degradation of the staging after decomposition of resin content on soil and groundwater does not constitute a hazard. According to the international standard, into two months to 6 months, biological decomposition rate should be above 60%. Plastic bags are qualified in biodegradable plastic bags. Dong Jinshi believes that domestic plastic bag manufacturing enterprises are in urgent need of transformation of the mode of production, in order preserve resources, protect the environment, in producing biodegradable. What is a biodegradable plastic? Biodegradable plastic would point to in the process of production to sign a certain regarding additives, such as starch, modified starch, photosensitizer, biodegradation, a lot of others.) Or other cellulose, stability, easy degradation in the planet. Test shows that many of biodegradable plastics in general environment exposure after 90 days begins to thin, weight loss, strength loss, gradually forced an entry pieces. If these pieces are buried in garbage or soil, the degradation effect is not obvious. All kinds of plastic products have greatly enriched people's life, but slowly waste plastic in the wild decomposition, completely decomposed to several decades, or even countless years, therefore the degradation of plastic and reuse troubles before today's all environmental chemists. Interestingly, however, degradable are not scientists have coded in the first stage. Scientists are developing or have developed biodegradable application range is relatively narrow, still can't replace the plastic of the masses. And, of course, we believe typically the near future, the degradation problems can be solved properly. Information from: plastic manufacturers
