Biodegradable plastics -- a new trend in the development of plastics industry in the future
Frontier: after a storm of environmental protection under the plastic market malaise, traditional crafts and materials already could not meet the requirements of sustainable development, the plastic industry in the future must be to go to the development of energy conservation and environmental protection, lightweight standard! And new plastic will become the object of future development research of plastic enterprises.
1.the development of the plastics industry wait and see
Most plastics are discarded after being consumed and used in one time. However, plastic is difficult to be degraded naturally in the environment. In 2018, the state will rectify the plastics industry, and the domestic environmental protection has never been stronger. It is certain that the plastics enterprises will develop towards renewable resources.
2.It is urgent to develop degradable plastics
Plastic problem becoming world-class puzzle, Bangladesh has suffered a catastrophic floods, plastic bags and blocked the drainage system, the plastic trash can cause hundreds of thousands of Marine animals die each year. But the good news is that in the present have biodegradable plastic, the plastic is refers to under the condition of nature, such as soil or sand, under certain conditions can be natural degradation, and eventually fully biodegradable materials such as carbon dioxide and water.
3.Development status of the renewable industry
China is an important supplier of biodegradable plastics in the world, accounting for about 20% of the global production capacity. From 2009 to 2013, the annual growth rate of biodegradable plastics was more than 21%. By 2016, China's biodegradable plastics had a capacity of 710,000 tons and a production capacity of 520,000 tons. Because the European countries to support the use of biodegradable plastics, the provisions of the state banned disposable plastic, make it easier for Europe to biodegradable plastics increased demand, in recent years, since the European supermarkets for purchasing a surge in complete biodegradable plastics, lead to serious shortage. At present, our country is the world's only can produce all kinds of biodegradable plastic products, but the present stage our country still rely on disposable plastic, biodegradable plastic demand is relatively small, leading to a large number of biodegradable plastic for export at home abroad.
Biodegradable plastics is now in the "evaluation is high, use very little", mainly because compared with the traditional plastic, biodegradable plastic cost is higher, price of traditional plastic two to three times; The poor performance of plastics requires special processing equipment, which in turn increases the manufacturing cost. Without the support of national policies, biodegradable plastics are difficult to popularize.
4. Future prospects
Not only in the plastic industry, but also in China's ultra-high speed economic development in recent years led to a dramatic increase in the problem. These problems have taken many developed countries hundreds of years to solve gradually, and China wants to solve them in 20 years or less, which will cause conflicts between the people and the country. At present, the "one size fits all" of environmental protection inspectors is also to accelerate the improvement of the country's ecological environment, which has not brought the development of market norms to the industry, leading to the outbreak of negative emotions among practitioners.
