Recycling & Sorting

Sorting is where recycling quality is won or lost. AI picking robots, sensor-based optical sorters and waste-stream analytics are designed to help recovery facilities capture more of what arrives, produce cleaner output and see what's on the belt.

Buying advice

Sampling duties can justify the analytics

In England and Wales, materials facilities must sample and report the composition of the waste they handle, and the Environment Agency's guidance asks for a minimum of one input sample for every 75 tonnes delivered by each supplier. The same guidance says visual detection and recognition technologies, including AI, can enable the automation of sampling, while the operator stays responsible for showing that results are representative and accurate. If you are weighing a Greyparrot Analyzer or another vision system, ask the maker how its data could support a sampling methodology your regulator will accept. Run it alongside manual samples for long enough to show the two agree.

Buy for the grades your offtakers pay for

A sorting line earns its keep from what reprocessors will buy, so start from their specifications rather than from the machine. ISO 15270:2008 gives guidance on recovering and recycling plastics waste, including quality criteria through the recovery process, and offers a shared vocabulary with plastics buyers. Regulation (EU) 2025/40 on packaging and packaging waste will alter the packaging arriving at your tipping floor as its requirements phase in, so plan for your input mix to keep changing over the life of anything you install. Ask reprocessors to confirm in writing which contaminants lead to rejected loads before you set the purity targets a robot or sorter must meet.

Quote the full installed scope

As of October 2026, price tags ran from the Greyparrot Analyzer at about $50,000 to the Steinert UniSort PR at about $350,000, and each one carried a price. Installation can involve conveyor changes, steelwork, compressed air or vacuum supply, controls integration and days of lost throughput while the line is down. Ask AMP Robotics, BHS, Pellenc ST, Redwave and Steinert to quote the complete installed scope against the same layout drawing, with wear parts, software licences and remote support itemised. Compare uptime guarantees, and how each maker measures uptime, before you compare purchase prices, because an idle unit on a busy line costs more than its depreciation.

Common questions

What's the difference between a sorting robot and an optical sorter?

Sorting robots use vision and a gripper or suction to pick individual items from the belt. Optical sorters typically use sensors and air jets to separate material at high volume. Many facilities use both.

Can analytics help without a sorting robot?

Yes. Vision-based analytics can monitor composition and purity on your conveyors, giving you data to tune existing equipment before you invest in more.
