Towards Sustainable Production of Chemicals and Fuels from the Fast Pyrolysis of Waste Polyolefin Plastics

2019
Ulises Gracida Alvarez

Summary

This thesis explores sustainable production of chemicals and fuels from the fast pyrolysis of plastic waste as a circular economy strategy, evaluating the technical and economic viability of converting plastic waste into valuable products. The work addresses the challenge of rising plastic waste generation and low recycling rates by examining thermochemical conversion pathways.

The increasing amount of plastic waste (PW) generation has become an important concern due to the leveled-off recycling rates. Therefore, governmental agencies around the world, including state governments in the United States, have proposed initiatives to minimize the amount of PW that is landfilled and encourage recycling or energy recovery. Circular economy is a strategy that attempts on reusing PW to produce new polymers while avoiding its disposal and the use of virgin material. Chemical recycling raises an interesting technology prospect due to the potential reduction of pollutant emissions and the establishment of a circular economy through the production of monomers and fuels.
