According to UNEP data, global plastic waste has reached 4.9 billion tons, only 9% of which has been recycled. As a major source of water, soil and ocean pollution, waste plastics that are difficult to degrade remain the world's 'difficult'.
On June 5th, it was the 47th 'World Environment Day'. The UN Environment Agency put forward the theme of 'plastic warfare' and called for a one-time plastic pollution problem. China also proposed 'beautiful China, I am an actor' this year. The Chinese theme complements it.
'Limited plastic order' effect 'happy and mixed'
China is a big country in the production and use of plastics. The annual consumption of waste plastics is more than 40 million tons, and it is growing at an annual rate of 8%. According to the China Plastics Processing Industry Association, in 2017, 31 provinces all produced plastic products, 15 The province's output has maintained a positive growth, recycling is not good, it will cause white pollution from the city to the countryside, from the mainland to the ocean.
In recent years, the quality of China's ecological environment has continued to improve, but the results have not been stable. The 'plastic limit order' introduced in 2008 is only part of the solution to consumer behavior, and a considerable part of agricultural waste plastics is not included in this category. Despite the National Development and Reform Commission. The principle of 'restricting batches, replacing batches, and standardizing batches' was put forward. However, the management of waste plastics generated in production, circulation, and consumption is still grim. In addition, plastics have penetrated into every aspect of life, and people have demand for plastics. Agricultural powers need to use agricultural mulch in large quantities, and supermarkets still need a lot of plastic bags.
Recycling of waste plastics is imminent
It is understood that the global treatment of waste plastics is landfill, incineration, regenerative granulation and pyrolysis. The landfill method is widely used, but the hidden dangers and hazards are relatively large, increasing the pressure on the use of land resources, refractory plastics. Seriously hindering the penetration of groundwater, the additives in plastics cause secondary pollution of the land. The same widely used incineration method, the production of toxic substances is difficult to deal with, and it is against the construction of waste-to-energy plants. Regeneration granulation methods also have limitations. A large number of inferior waste plastics cannot be used for regenerative granulation and waste water resources, which is not the ultimate solution.
In this context, the treatment of waste plastics has become the direction that countries strive to overcome. The recycling of waste plastics is 'systematic engineering'. On the one hand, it needs to continue to strengthen control from the source, and guide plastics producers to consider recycling. On the other hand, recycling Focus on building a waste plastic recycling system. Plastic is a petroleum product, and it is reduced to oil. This is a real cycle. Each recycling of 1 ton of plastic can save 3785-7570 liters of gasoline. We need to clarify the use of waste plastic. Renewable resources, the energy utilization of waste plastics as an important component to improve China's energy-saving emission reduction and development of circular economy.
Pyrolysis technology becomes a breakthrough
Compared with the waste plastic processing technology mentioned above, the outstanding pyrolysis technology has been receiving more and more policy support and industry recognition in recent years. This technology truly realizes the harmless, resource-based treatment and safety of waste plastics. Environmental protection, high efficiency and energy saving advantages.
Pyrolysis refers to the process of utilizing the thermal instability of organic matter in solid waste to be thermally decomposed in a pyrolysis reactor. This technology can convert waste plastics into high value-added energy products such as fuel oil, natural gas, and solid fuel. It is the most important ultimate treatment for polymer waste.
In recent years, the scale of environmental protection equipment manufacturing has expanded rapidly, the development model has been continuously innovated, the service field has been continuously expanded, and the technical level has been greatly improved. Jinan Hengyu Environmental Protection Technology Co., Ltd., a leading company in the pyrolysis industry, has independently developed environmentally-friendly continuous waste plastics. The pyrolysis technology equipment realizes the resource utilization and harmless treatment of waste plastics. The equipment is awarded the National Science and Technology Progress Award for its excellent safety and environmental protection, energy-saving and high-efficiency performance, and long-term continuous and stable operation. The equipment is exported to Germany, Hungary. Brazil, Estonia, Thailand, India, Malaysia, Iraq, Taiwan and many other countries and regions around the world.
In a limited environment, there are not many resources to waste. Declaring war on plastics is not without plastics. It is also a resource. It requires technological innovation and new solutions to achieve effective recycling and meet the needs of social development. Technical equipment recycles and treats waste plastics, turning waste plastics into products or converting them into secondary materials for reuse, and vigorously promoting the development of green recycling and low carbon!
