Feedstock Recycling and Pyrolysis of Waste Plastics: A Comprehensive Analysis 1. Introduction

The accumulation of non-biodegradable plastic waste (PW) has become a global crisis, particularly in developing nations with inadequate waste management infrastructures. Mechanical recycling, while efficient for clean, single-stream plastics like PET, often fails to handle mixed, contaminated, or multi-layered materials. Feedstock recycling, or chemical recycling, addresses this by breaking down plastic polymers into their original monomers or other valuable chemical feedstocks. Pyrolysis, a thermochemical decomposition process occurring in the absence of oxygen, stands out as a primary technology for converting these "hard-to-recycle" wastes into liquid fuels and chemicals. 2.
