Segmentation by types of advanced recycling technologies classifies the market into four distinct categories: mechanical recycling, chemical recycling, thermal recycling, and biological recycling. Mechanical recycling, the most established pathway, involves size reduction, washing, and re‑extrusion, primarily serving commodity-grade plastics and accounting for the bulk of current capacity. Chemical recycling, subdivided into depolymerisation, solvolysis, and pyrolysis, breaks polymers to monomers or fuels, thereby expanding feedstock flexibility and addressing hard‑to‑recycle streams. Thermal recycling, including gasification and incineration with energy recovery, provides a fallback for residual waste, contributing to overall energy efficiency metrics. Biological recycling leverages enzymatic or microbial processes to convert waste into biochemicals, representing an emerging high‑value niche with substantial R&D investment. Each type adds a discrete revenue stream, with market share proportionate to technology maturity, capital intensity, and regulatory support, collectively defining the market’s growth trajectory.
