Practical guides to waste sorting, recycling and recovery technology — how the systems work and what they deliver.

Packaging waste sorting (LWP): how lightweight packaging is separated

Lightweight packaging (LWP) is the yellow-bin mix of plastics, cartons and metals. Here is how a packaging sorting plant separates it into clean fractions.

PET and rPET sorting: how PET bottles become food-grade recyclate

PET is the most recycled plastic, but only clean, well-sorted PET earns a top price. Here is how PET bottles and rPET are sorted by colour and polymer.

Tyre recycling: shredding and pyrolysis of end-of-life tyres

End-of-life tyres are a concentrated waste stream with real recoverable value. Here are the two main routes — shredding to granulate and pyrolysis — and what each produces.

How an optical (NIR) separator works in a sorting plant

Optical separators are the workhorse of automated sorting. Here is how near-infrared sensing and air-jet ejection separate plastics by polymer and colour.

RDF vs SRF: what is refuse-derived and solid recovered fuel, and how is it made?

RDF and SRF turn the non-recyclable, high-calorific fraction of waste into fuel for cement kilns and energy plants. Here is the difference and how a preparation line works.

What is a waste sorting plant, and how does a sorting line work?

A waste sorting plant separates mixed waste into clean recyclables and recovered fuel. Here is how a modern sorting line is built, stage by stage.
