Best Recycled Product: Carbon8 Aggregates

Carbon8 Aggregates (C8A) has developed the first Air Pollution Control Residues (APCr) recycling plant in the UK and Europe, solving a longstanding problem that has meant that Energy from Waste plants could not deliver ‘zero waste to landfill’.

The company has taken a novel laboratory based technology, known as Accelerated Carbonation Technology (ACT), through to commercial reality in the production of a lightweight, carbon negative, aggregate. C8A believes its aggregate is the only product recycled from APCr with End of Waste status.

During the mass burn, a typical EfW will produce 10,000 tonnes of APCr, approximately 3% of the waste input by weight. APCrs are classified as a hazardous waste and currently, the vast majority of the APCr produced in the UK goes to landfill either via treatment with water, treatment with waste acid, washing or directly into long term storage in the salt mines in Cheshire.

C8A’s plant in Brandon, Suffolk, offers a commercial recycling solution that uses a patented process to treat the APCr, while capturing carbon dioxide and stabilising heavy metals in the waste. The aggregate manufacturing process produces no emissions and no waste. All the production is currently being used in the manufacture of dense and medium dense blocks at the Lignacite blockworks where the C8A plant is located.

The judges said: “This is an impressive technology development. It demonstrates real innovation building on a project trial and offers real export potential.”

Sponsor’s comment from Recolight:

Recolight, the only specialist WEEE compliance scheme for the lighting industry, was set up by the industry to provide WEEE compliance and free lamp recycling for all business waste lamps across the UK.
This service is free because we operate as a non-profit organisation, funded by our members. Our network of 2,200 collection points across the UK includes over 800 consumer recycling points for low-energy light bulbs.
We are dedicated to keeping waste lamps out of landfill. To date we have funded the recycling of over 175 million household and business lamps, preventing over 700kg of mercury from entering landfill.
