identical composition to mix efficiently. There are two principal ways of recycling PVC: Mechanical recycling: PVC waste is ground into essay on radhakrishnan small pieces that can be easily processed into new PVC compounds ready to be melted and formed into new products. This closed-loop operation has taken place since the 1970s and has made the production of some plastic products amongst the most efficient operations today. In the long run, the toxic substances attributed to these plastic bags end up in the food chain as they are transformed into microscopic particles (World-Wildlife-Fund-Report, 2003). The phase boundaries cause structural weakness in the resulting material, meaning that polymer blends are useful in only limited applications. Since the number of landfills continues to diminish, keeping plastic containers out of landfills is important.

Marine life is affected by plastic bags disposed into the sea, for instance the case spotted at the North of the Arctic Circle as well as the South close to the Falkland Islands (Moorthy, 2010).

As landfill is being progressively restricted within the European Union, recycling will gradually become the principal option for many end-of-life PVC products. However, this type of plastic is limited by its high cost of production as well as the fact that it cannot be recycled. Only use cling films designated as suitable for use in microwave oven.

However, just as other great inventions, say, nuclear energy and biotechnology, plastic bags are causing serious issues like global warming, environment pollution and energy consumption. They have not been tested safe for food storage and they may contain non-food residues that contaminate food.
Without doubt, it is the plastic bag. The plastic bag is the most usual and integral part of our life. This problem should therefore be solved through methods such as recycling and use of degradable plastic. Get a Price".
