Recycling, as a topic, encompasses the collection, separation, processing, and reintroduction of post-consumer or post-industrial materials into manufacturing cycles to displace primary raw resources. Scientifically, it involves material-specific pathways such as mechanical and chemical recycling for polymers, re-smelting and refining for metals, and deinking and pulping for paper fibers. Research addresses process efficiency, contamination control, life cycle assessment (LCA), and system-level optimization of material flows within circular economy frameworks. Key metrics include recovery rates, material quality retention, embodied energy, and net environmental impact relative to landfilling, incineration, or virgin-material production.
"Reduce, reuse, recycle." For more than 50 years, those three Rs have been the world's go-to environmental mantra.
