When discussing the types of chemical recycling, it is important to know exactly what advanced recycling (or Feedstock Recycling) is. This type of recycling uses technologies that result in diverse processes to break down plastics into other new materials that are challenging for mechanical recycling to break down and create. This process can include heat or other methods of compression that allow plastic polymers to be reused or up cycled.
Why Choose Chemical Recycling?
Chemical Recycling is a great method for heavy contaminated plastics or plastics that are harder to recycle. Advanced Recycling acts as a replacement or substitute for a landfill where plastic waste would end up.
What are the Types of Chemical Recycling?
There happen to be several types of chemical recycling methods. With Chemical Recycling being relatively new, there are additional terms and phrases used to describe the types of recycling processes. Below are just a few terms that are relevant when discusses the types (which are also listed below):
- Purification = This involves solvents to remove additional additive properties from the polymers.
- Hydrogenation = The breakdown of polymers using heat and hydrogen to create fuel or other products.
- Gasification = The process of heating non-recyclable material or plastic with oxygen, creating fuel such as ethanol or methanol.
- Pyrolysis = The process of plastic being heated without oxygen that generates hydrocarbons that can be used as fuel as well, similar to hydrogenation. The method turns waste into crude oil that can be refined as gasoline or wax. In Chemical Recycling, this process can remove chemicals and other additives that are harmful.
