Plastic Recycling
Plastic recycling is the process of recovering waste or scrap plastic and reprocessing these materials into other functional and practical products. Because almost all plastic is non-biodegradable, it must be recycled as part of the global efforts to reduce plastic and other solid waste in the environment.

Questions and answers
Frequently asked about plastic recycling
What equipment is used in plastic recycling?
A typical plastic recycling line combines sorting (manual and automated, including NIR and AI-driven optical sorters), size reduction (shredders and granulators), washing and decontamination, and finally extrusion or pelletizing to turn clean flake into recycled resin such as rPET, rHDPE or rPP.
What types of plastic can be recycled?
PET (#1) and HDPE (#2) are the most widely recycled resins, with growing markets for rPP (#5) and rLDPE (#4). PVC (#3), polystyrene (#6) and mixed or multilayer plastics (#7) are harder to recycle and usually need more specialised technology.
What is the difference between mechanical and chemical plastic recycling?
Mechanical recycling shreds, washes and re-melts plastic into new pellets — the most common and cost-effective route for clean, single-resin streams. Chemical recycling breaks plastic down into base monomers or feedstock, which can handle more contaminated or mixed plastics but typically needs a larger capital investment.
What affects the quality of recycled plastic such as rPET or rHDPE?
Odour, colour consistency, residual contamination (labels, adhesives, other polymers) and moisture are the most common quality issues. Investing in washing, decontamination and sorting accuracy has the biggest impact on the quality of the recycled output.
How do I find an equipment manufacturer for plastic recycling?
Use the Manufacturers Directory A–Z or the Equipment Guide. Partner profiles carry direct contact details; other listings link to the company website.
