There are many kinds of shopping bags. Somebody thinks that the biodegradable shopping bags are the best, they will not produce pollutions after use and discarding.
That is a wrong thought. Vice president of international food packaging association, Dong Jinshi says that, in order to ensure the resilience of plastic bags, currently on the market there are only 1 / 3 to 1 / 4 biodegradable plastic bags are with biodegradable ingredients, the others are difficult to degrade. Degradation of components according to the different degradation time of biodegradable plastic bags takes months to years. Although more than white trash ‘digest’ a short time a lot, but after a lot of waste in the environment is still very serious. Meanwhile, the current biodegradable plastics, there are still relatively low intensity (not strong), the problem of high cost. Therefore, the solution is not biodegradable plastic shopping bags polluting the most effective way. Relative to the recycling bag, now more international focus is to reduce the use of the premise of effective waste plastics recycling.Plastic shopping bags are consumable products in daily people ‘s life , every year China consumes a lot of plastic shopping bags. Plastic shopping bags provide convenience for consumers, while, due to excessive use and recycling is not in place and other reasons, also caused a serious waste of energy resources and environmental pollution. In the ‘plastic limit’ implementation occasion of the year, many people mention this topic again - mixed, revived. Policies promulgated by the state policy require each person's understanding of consumer behavior and good co-ordination. Plastic shopping bags have been deep into the details of everyday life inside; Less and recycling use become everyone's responsibility.Reusable bags or reusable shopping bags are not just concern that whether the material is environmentally friendly, but also the consumer behavior. And it is the most critical one. No matter what kind of material shopping bags, if consumers do not use will result in waste and pollution.
