Chemical Recycling of Waste Plastics: Turning Waste into Treasure and Saving Our Planet

Imagine a world where old plastic bottles can power cars. This is no longer science fiction. Converting waste plastics into fuel, as an important part of chemical recycling of waste plastics, is not only possible, but is also developing rapidly, bringing huge benefits to the global environment. This blog post explores the process principles, environmental benefits, and socio-economic benefits of converting waste plastic to fuel, and provides successful cases to demonstrate its impact.

Pyrolysis Technology: The Core of Chemical Recycling of Waste Plastics

In recent years, chemical recycling of waste plastics has become a topic of global concern due to the policies of many countries in the world and the strong investment of international mainstream petrochemical, brand and packaging giants. Chemical recycling of waste plastics is the process of converting plastic waste through a series of chemical transformations to generate intermediate chemicals such as oil, gas, and charcoal. Wanrong Technology's pyrolysis technology provides an effective solution for chemical recycling of waste plastics. In an oxygen-free environment, waste plastics can be converted into plastic oil, carbon black, and pyrolysis gas. Pyrolysis gas can be reused in the system, and carbon black and plastic oil can be recycled after deep processing.

 

Chemical recycling of waste plastics: environmental and economic benefits are equally important

The intermediate products of waste plastic pyrolysis are plastic oil, carbon black, and pyrolysis gas. Based on actual production experience, without considering the environmental premium, assuming that the average oil yield of plastic waste in fresh domestic waste is about 75%, the product is introduced into the direction of finished oil to make fuel, and the price per ton is 2,400 yuan, that is, the output value of each ton of waste plastic is about 2,400 yuan; the product is introduced into the direction of monomer to make new plastics, and the price per ton is more than 6,000 yuan, that is, the output value of each ton of waste plastic is about 4,500 yuan. Market factors affect the output value of waste plastic pyrolysis, and there will be a certain market fluctuation.

 

The chemical recycling technology of waste plastics can replace the incineration of plastic waste, fix the carbon in the product instead of releasing it into the atmosphere, thereby greatly reducing carbon emissions. The LCA report of international chemical giants and chemical recycling companies shows that chemical recycling of waste plastics can reduce carbon emissions by about 50% compared with the incineration of plastic waste, that is, the disposal of 1 ton of waste plastics can reduce carbon emissions by more than 2 tons.

Climate change is one of the world's urgent issues, and chemical recycling of plastics will effectively alleviate climate problems.

 

Successful cases of chemical recycling of waste plastics around the world

This benefit is not just theoretical, there are many successful examples around the world. For example, several cities in India use pyrolysis technology to manage plastic waste, with remarkable results. Kenyan social enterprises develop low-cost pyrolysis equipment to provide sustainable energy for the local area. China's Wanrong pyrolysis technology has also achieved the transformation of domestic waste plastics into fuel oil and pyrolysis carbon. It is currently developing strategic cooperation with Sinopec to achieve chemical recycling of waste plastics to waste plastics.

 

In short, under the chemical recycling technology of waste plastics, waste plastics are converted into fuel oil, or then into new plastics, which has environmental benefits and social and economic benefits. With the development of technology and the promotion of application, chemical recycling of waste plastics is expected to bring significant positive impacts to the earth.
