Secondaryrecycled

Secondaryrecycled is a term used in waste management and the circular economy to describe materials that have already undergone recycling and are subjected to further recycling processes. It refers to the continuation of material recovery beyond the initial recycling loop, often to recover additional materials, improve sorting and cleanliness, or convert the material into new products with different properties. Secondaryrecycled materials sit between primary (closed-loop) recycling and tertiary or chemical recycling in the hierarchy of material recovery.

The scope of secondaryrecycling includes mechanical and physical processes such as cleaning, sorting, shredding, and reprocessing of already recycled streams. Examples include post-consumer plastics that are reprocessed into fibers or lower-grade plastic resins, metal scrap remelted to produce new alloys, and paper subjected to additional pulping and de-inking to yield secondary grades. The aim is to maximize material recovery, reduce waste, and extend the life of resources, often under the umbrella of a cascade approach to recycling.

Applications of secondaryrecycled materials are typically in less demanding or non-critical products where strict purity is less essential. While this approach can lower costs and conserve resources, it also faces challenges such as contamination, quality degradation, and market volatility. The economic viability of secondaryrecycling depends on feedstock quality, processing technology, and the demand for lower-grade products.

Related concepts include primary recycling, tertiary or chemical recycling, downcycling, and the broader principles of the circular economy. Secondaryrecycled materials illustrate how recycling can be extended beyond the first pass to further conserve resources, though outcomes vary by material stream and product requirements.
