In today's world, environmental protection and resource issues have become a reality that can not be avoided by global economic development. Up to now, the international community has developed more than 150 environmental and resource-related treaties. Countries around the world to develop environmental protection regulations are more and more, and in the protection of human living environment plays a very important role. Green economy has become the world economic development trend.
First, the promotion of the use of wood-plastic composite materials can reduce the pollution of waste plastics on the ecological environment
With the rapid development of China's plastics industry, production and living waste plastics are also increasing year by year. According to the China Plastics Association Waste Plastics Utilization Committee statistics, the annual total amount of waste plastics has been as high as 7 million tons. These waste plastics include both hollow bottles, plastic bags and other disposable packaging materials, including the use of agricultural film and industrial waste, the governance approach is usually landfill or incineration. Related research shows that the waste plastics in the landfill after 200 years to break down, and the decomposition process will dissolve toxic substances, causing damage to the soil. The burning of waste plastics usually leads to the release of harmful gases, affecting air quality and the surrounding environment. Therefore, known as the "white pollution" of waste plastic pollution of the environment, has been highly concerned about the environmental protection industry. Wood-plastic composite materials using waste plastics as raw materials, can maximize the use of waste plastics, waste plastics to reduce environmental pollution.
Second, promote the use of wood-plastic composite materials can reduce the impact of waste crops on the ecological environment
According to statistics, China's annual about 600 million tons of straw need to be processed. In addition to the prevention of incineration of air pollution, in addition to the airport, highways, important railway lines, high-voltage transmission lines and scenic spots, nature reserves, population concentration and its surrounding areas to prohibit the incineration system, increase the ban on burning , The state every year need to allocate a certain amount of special costs, used to support the straw gasification technology and other comprehensive utilization measures, the development of industrial use of straw a new way. 2000 to 2001, Hebei Province, only for the recycling of special costs of straw is as high as 60 million yuan. Wood-plastic composites use waste crops as raw materials to maximize the use of waste crops and reduce the environmental pollution of waste crop incineration.
Third, the promotion and application of wood-plastic composite materials to avoid soil erosion on the destruction of the ecological environment
Known as the "lung of the earth," said the forest resources, the protection of the ecological environment has an irreplaceable role. Deforestation caused by soil erosion, dust storms, floods, the culprit. Afforestation, protection of forest resources is a long-term national policy. The National Environmental Protection Administration's "Tenth Five-Year Plan" has clearly set out the task of maintaining the ecological functions of forests, strictly managing forest resources, increasing forest protection, extending deforestation, and restricting logging. It aims to protect the ever-decreasing forest resources, Environmental balance. The promotion and application of wood-plastic composites and their products can replace part of the wood products, minimize the deforestation and protect the ecological environment.
