Feedstock recycling

Feedstock recycling, also known as “chemical recycling,” is the process of breaking down collected plastics into monomers and other basic chemical elements (“depolymerization”). This is an attractive option for plastic products that are difficult to recycle mechanically due to low quality, composite nature or low economic value. These monomers can be used as virgin material alternatives in manufacturing new polymers.

Feedstock recycling includes conversion process such as:

  • Pyrolysis: the creation of syngas and liquid fuels through the chemical and thermal decomposition of a material at high temperatures and in the absence of oxygen
  • Gasification: the creation of syngas from the leftover char from pyrolysis using extremely high temperatures and minimal oxygen

Hydrogenation: the creation of syncrude (liquid and gaseous) through the application of hydrogen in a high temperature and pressure environment
