Pyrolysis oil is expected to become a new path for the conversion and utilization of waste plastics
Xinhua News Agency, Shenyang, August 30 (reporter Yu Yitong, Li Yujia) for a long time, the recycling and environmental protection of low residual value waste plastics has been a pain point in the industry. At the 2nd China Recycled Plastics Industry Standards and Technological Innovation Conference, which opened in Shenyang on the 30th, industry experts believe that the development of pyrolysis oleification technology will provide new ideas for the recycling treatment of waste plastics.
"At present, the recycling and recycling of waste plastics in China is far from keeping up with the development of the situation." Sheng Min, secretary-general of the recycled Plastics branch of the China Renewable Resources Recycling Association, said, "Due to the insufficient degree of automation in the recycled plastics industry, the sorting technology needs to be further improved, resulting in the quality of recycled materials is reduced, and after 1-2 times of recycling, it will become unrecyclable plastic waste."
In the view of Zhou Hongchun, a researcher at the Development Research Center of The State Council, it is necessary to use the idea of circular economy to solve the problem of waste plastics. In recent years, the continuous research and development of waste plastic pyrolysis oil technology has found a new way to treat low residual value waste plastics.
According to the "Development Status of China's recycled plastics Industry in 2019" released by the conference: This year, including Sinopec, SABIC and other foreign petrochemical giants in China have paid unprecedented attention to this technology, and have begun to industrialization research and development of waste plastic pyrolysis oil technology and large capacity continuous production equipment, some environmental protection technology enterprises outside China have also made substantial technological breakthroughs, and large-scale clean production equipment for waste plastic pyrolysis oil is about to achieve industrial production.
According to reports, the oil production rate of the new technology of waste plastic pyrolysis oil can be as high as 80%, and the solid waste residue can be harmless treatment. The breakthrough of this technology will change the long-term recycling of waste plastics in China can only rely on the single method of physical recycling and recycling, which can convert low residual value waste plastics into plastic oil through cracking technology. And then used as raw materials for the production of new plastics, to achieve the "oil - new plastics - waste plastics - plastic oil - new plastics" plastic circular economy closed-loop industrial chain.
"The physical recycling and recycling of high-quality recycled waste plastics and the chemical recycling and recycling of low residual value plastic waste can completely" eat up the waste plastic resources and make new contributions to environmental protection and circular economy." Sheng Min said.
