Wide wood plastic materials protect the ecological environment

In today's world, the issues of environmental protection and resources have become practical issues that cannot be evaded in the development of a globalized economy. To date, the international community has established more than 150 treaties related to the environment and resources. Countries around the world have more and more environmental protection laws and regulations, and they play a very important role in protecting human living environment. The green economy has become the trend of world economic development.
Since the reform and opening up, the rapid economic development and the large population of China have made the tasks of ecological environmental protection more arduous. According to the "Tenth Five-Year Plan for National Eco-environmental Protection" issued by the State Environmental Protection Administration in March 2002, the current situation of China's ecological environment is still very severe. The scope of ecological deterioration is still expanding, the degree is increasing, and the damage is increasing. The regional ecological balance is seriously misaligned. The ecological environment in the upper reaches of the rivers, such as the Yangtze and Yellow Rivers, is seriously out of balance. The important lakes and wetlands along the rivers are shrinking. Rivers stop flowing and lakes dry up. The groundwater level drops seriously, the forest vegetation is degraded, the ecological function is reduced, and floods and sandstorms occur. Intensified. From this perspective, to promote the technological revolution and develop the economy, we must put environmental protection in an extremely important position.
First, the promotion and application of wood-plastic composite materials can reduce the pollution of waste plastics to the ecological environment. With the rapid development of China's plastics industry, waste plastics produced and produced in daily life have also increased year by year. According to statistics of the Waste Plastics Utilization Committee of the China Plastics Association, the total amount of waste plastics in China has reached more than 7 million tons annually. These waste plastics include not only disposable packaging materials such as hollow bottles and plastic bags, but also used agricultural plastic film and industrial waste. The treatment method is usually landfill or incineration. Relevant studies have shown that waste plastic can not be decomposed until more than 200 years after landfilling, and toxic substances will be dissolved during the decomposition process, 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, the environmental problems caused by waste plastics known as "white pollution" have always been highly concerned by the environmental protection community. Wood-plastic composite materials use waste plastics as raw materials, making maximum use of waste plastics and reducing the environmental pollution of waste plastics.
Second, promote the use of wood-plastic composite materials can reduce the impact of abandoned crops on the ecological environment According to statistics, China's annual about 600 million tons of straw needs to be processed. In order to prevent air pollution caused by incineration, in addition to prohibiting the incineration system at airports, highways, major rail lines, high-voltage transmission lines, scenic spots, nature reserves, population concentration areas and the surrounding areas, and increasing the prohibition of law enforcement on burning. Each year, the state needs to allocate a certain amount of special expenses to support the straw gasification technology and other comprehensive utilization measures, and to develop new ways for industrial use of straw. From 2000 to 2001, only Hebei Province spent more than 60 million yuan on special expenses for recycling straw. Wood-plastic composite materials use abandoned crops as raw materials to maximize the use of abandoned crops and reduce the environmental pollution caused by incineration of discarded crops.
Third, the promotion and application of wood-plastic composite materials can avoid the destruction of water and soil erosion on the ecological environment. It is known as the "earth of the earth" of the forest resources, the protection of the ecological environment has an irreplaceable role. The loss of soil and water caused by deforestation is the culprit for sandstorms and floods. Afforestation and protection of forest resources are a long-term national policy of our country. The State Environmental Protection Administration's “Tenth Five-Year Plan” clearly proposes the maintenance of the ecological functions of forests, the strict management of forest resources, the strengthening of forest protection, the extension of harvesting cycles, and the limited control of harvesting tasks in order to protect the ever-decreasing forest resources and maintain the ecology. Environmental balance. The promotion and application of wood-plastic composite materials and their products can replace a portion of wood products, minimize forest deforestation, and protect the ecological environment.
According to calculations, the promotion of the use of wood-plastic composite materials of 1 million tons can dispose of nearly 500,000 tons of waste plastics and use more than 500,000 tons of abandoned crops, which is equivalent to more than 3,000 acres of medium-density forests.
Integrating the above factors, promote the use of wood-plastic materials, reduce the white pollution caused by waste plastics that are difficult to degrade, open up new ways for industrial use of agricultural waste, reduce the air and environmental pollution caused by straw burning, and reduce the amount of forest cutting, for the protection of forest resources, It is of great significance to improve the ecological environment.
