Feedstock Recycling and Pyrolysis of Waste Plastics: A Comprehensive Analysis 1. Introduction Feedstock Recycling and Pyrolysis of Waste Plas...
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. The Pyrolysis Process: Mechanisms and Parameters A carbonaceous residue that requires careful management but
Pyrolysis involves heating plastic waste to temperatures typically between and economic landscapes of .
This paper explores the technical, environmental, and economic landscapes of . As global plastic production continues to surge, traditional mechanical recycling and incineration face significant limitations, positioning chemical recycling—specifically pyrolysis—as a critical pathway toward a circular economy.
