Foreign degradable plastics industry development prospects may be of

With the increasingly prominent issue of plastic pollution , degradable plastics gradually favored by the market , in foreign markets , the rapid growth in demand , according to statistics , they are biodegradable plastics demand will annually at a rate of twelve percent faster growth the development of light footsteps .

From the analysis of the types of degradable plastics in North America , in 1989 , total sales of 880,000 tons of biodegradable plastic , biodegradable plastic which is 16 million tons. Then forecast to 2000 , total demand for degradable plastics 320 tons, of which 1.1 million tonnes of biodegradable plastics , biodegradable plastic is 1.05 million tons of light , the light - biodegradable plastics is 90 million tons, 150,000 tons of other biodegradable plastics , 1994-2000 , the annual average growth rate of 7.1% biodegradable plastics , biodegradable plastic light 9.6% , light - biodegradable plastics was 11.2 %, other 5.3% biodegradable plastic pursuant to predict light - biodegradable plastics growth will be fastest.Wholesale masking tape


Degradable plastics degradation caused by environmental conditions can be divided into light -degradable plastic , biodegradable plastics , chemical degradation of plastics , biodegradable plastics and other combinations . At present, production of degradable plastics world countries are the United States , Japan, Germany , Italy, Canada, Israel and other countries, varieties degradation bright , light / bio- degradable , biodegradable collapse of completely biodegradable plastics.

Biodegradable plastics in the world is mainly an aliphatic polyester or an aliphatic polyester manufactured by mixing starch . Aliphatic polyesters include synthetic oil as raw material polycaprolactone (PCL), polybutylene (PBS) and its copolymers , as well as renewable resources as raw materials to produce polylactic acid , polyethylene produced by microorganisms hydroxy butyric acid (PHB) and the like. Biodegradable plastics are decomposed and become water and carbon dioxide , and therefore will not cause harm to the environment.Masking tape


In order to improve the physical properties of the aliphatic polyester , the production of biodegradable plastics countries are terephthalic acid or a nylon polymer by way of an aliphatic polyester copolymer and aromatic. Soon, high performance biodegradable plastics will continue to be developed. As a catalyst for environmental technologies using enzymes instead of one heavy metal chemical catalyst process synthetic polymer materials will also be available. In addition to the aliphatic polyester , the polyphenols, polyaniline, polycarbonate, poly aspartic acid , etc. have been developed .Washi tape


Currently, biodegradable plastics can only be used to make some sporting goods ( fishing with silk , golf tees , etc. ) , agriculture, forestry and fisheries materials ( films , moisturizing materials, seedbed materials, etc. ) , garbage bags and hygiene products ( disposable diapers , etc. ) . It is very broad new uses , such as for the production of cosmetic containers, toothbrushes , cushioning materials, packaging materials , shopping bags, single-use gloves. If the security issue is resolved, it can also be used to make food containers . As a new functional polymeric materials, biodegradable plastics can also be applied to fertilizers, pesticides radical packaging materials and medical supplies packaging. In future, adhesives, printing inks and other non- plastic areas can also be opened purposes.Sellotape


The future development of environmental biotechnology, particularly biodegradable plastics and other products, market risk, policy risk is minimal , and biotechnology in China after 20 years of development, environmental protection is applied right time . It is foreseeable that in the bio-economy through effective organization of the park , take advantage of integrated technology, capital , and other aspects of the mechanism , can achieve industrialization in a relatively short period of time.
