"Plastic limit": the development of new environmental protection materials is the kingly way

Author: ComeFrom: Date:2017/7/20 15:02:08 Hits:2009
        Although the "plastic limit" has been issued for many years, but sadly, still make the line more than the phenomenon. On the one hand, we are calling for reducing the use of plastic bags. On the other hand, they are making use of plastic bags in order to rationalize the use of plastic bags. "Plastic only" means "selling plastic"". And "pay transaction", it is inevitable that people directly regard it as a normal transaction of peace of mind, which has fundamentally separated from the "plastic limit" theme.
        It can not be denied that plastic bags do play an important role in our daily life, but it brings convenience to our daily life, but it also inevitably becomes the "killer" of the environment". A paper "plastic limit order", which limits not only the white pollution sources, but also the living habits that people have formed. If there is no suitable alternative, then continue to implement, will inevitably have little effect. In order to solve this problem, many research teams at home and abroad have actively tackled technical problems and developed various types of environmentally friendly alternative materials.
        Shrimp shell
        According to foreign media reports, a team of biological engineering University of Nottingham recently and the Nile University researchers are studying the chitosan (Chitosan), which is a synthetic polymer produced from shrimp shell waste in. The aim of the study is to produce a biopolymer nanocomposite suitable for the Egyptian environment, which can replace polyethylene in plastic shopping bags.
        Using biodegradable polymers made from shrimp shells to make plastic bags can not only reduce carbon emissions, but also reduce food and packaging waste accumulated in streets or illegal dumping sites. All non biodegradable plastic bags come from fossil fuels, which can not only reduce carbon emissions, but also extend the shelf life of the food.
        Natural starch and vegetable oil synthetic materials
        India's emerging company, EnviGreen, uses natural starch and vegetable oil to synthesize a plastic material that, despite its shape and structure, looks like plastic, but does not contain any plastic or toxic substances. EnviGreen bags don't dissolve, drip, or release poisonous gas in the process of burning. You can even handle this plastic bag by eating".
        This pure organic material is 100 percent biodegradable and will never damage the environment. This shopping bag is discarded, can be within 6 months completely natural degradation; if they are placed in room temperature water, they will dissolve in one day disappear; and if the bag is placed in boiling water, it will decompose faster, probably only need 15 seconds.
