, more plastic waste should be recycled overall. Solving this challenge and building a more circular economy for plastics requires innovation and joint efforts across the value chain. BASF will contribute to this by developing innovative technologies and products that promote the recycling of plastics....
However, plastics are very slowly degraded in nature, and current recycling of used plastic materials is inefficient, which raises growing concern due to the widespread use of plastics. Inherent values of plastics are easily underutilized because many of them are treated as waste even after a ...
Chemical recycling of plastics by pyrolysis is a self-sustaining process step that does not require additional energy. It covers the relatively small energy demand to degradate the polymers into small molecules at higher temperatures through energetic utilization of gaseous and solid by-products, and ...
State-of-the-art of chemical recycling via pyrolysis: From experiment, over model, to process Several review papers have been written over the past 40 years discussing the experimental characterization and kinetic modeling of the pyrolysis of plastics. For instance, Dickens reviewed early TGA studies...
Chemical Recycling of Waste Plastics: Catalytic Cracking of Heavy Oil from Waste Plastics over Ni-Rey Zeolite The increasing amount of waste plastics which causes serious pollution problems is a cheap and abundant source of chemicals and energy. Chemical recycling method which recovers hydrocarbons is ...
The other way is mechanical recycling, which crushes waste to make new plastic products. 化学回收是回收废塑料的两种主要方法之一。它分裂聚合物链并产生诸如油之类的产品。另一种方法是机械回收,将废物粉碎以制造新的塑料产品。 Mechanical recycling is a good way to recycle engineering plastics, plastic ...
John Sewell, Secretary General of Chemical Recycling Europe talks about the role of chemical recycling in the plastics recycling industry, the…
Now, ten years into research and development, Recycling Technologies is targeting complex, often contaminated food packaging that can’t be recycled mechanically. Adrian Griffiths: It’s films, and it’s…it’s crisp packets, and it’s just all the type of plastics which normally people don’...
of plastics that can be recycled. Shell is working on several technologies to utilize waste in the circular economy but is focusing particularly onchemical recycling through pyrolysis, where hard-to-recycle plastic waste like snack bags, ready meals, or plastic film, that are not suitable for ...
Introduction to chemical recycling at SÜDPACK Mr Hardow, how does chemical recycling work? Dirk Hardow:In chemical recycling,used plastics are converted into pyrolysis oilin a high-temperature process under exclusion of oxygen. This oil can be used for the production of plastics and thus replac...
