Carbon8 to expand with third plant

Carbon8 avonmouth

A firm that turns energy-from-waste (EfW) residues into aggregate has won planning permission to build a £4m facility on the outskirts of Leeds.

Carbon8’s third plant will be based on the design of its flagship Avonmouth facility (pictured), which has just finished undergoing final performance testing as part of the commissioning process.

The two-line facility will be capable of processing 50,000 tonnes of waste flue gas treatment residues (FGTr) from EfW plants into approximately 110,000 tonnes of lightweight secondary aggregate.

Work is expected to begin in August on the 13-acre site, part of an industrial estate at Cross Green, after plans were approved by Leeds City Council.

The firm, a subsidiary of Grundon Waste Management, expects the plant to create more than 20 jobs when operational.

Stephen Roscoe, Carbon8’s technical director, said: “We’re delighted to have secured the go-ahead for our third facility, the first in the north of England, and believe this confirms our position as the market leader in FGTr recycling.

“We are already in advanced discussions regarding contracts for more than 50% of the FGTr into Leeds and, due to the imminent closure of coal-fired power stations in the region, we are also seeing strong demand from block makers for our aggregate, which will replace the power station ash frequently used in block manufacture.”

The joint planning application for the site was submitted with local independent block maker Thomas Armstrong, which will build a new production plant alongside Carbon8’s aggregate operation. Armstrong trades as Stocks Blocks.

Roscoe said the Avonmouth plant, built in 2015, had performed well during commissioning and the firm had accepted handover of the facility on time and in budget.

“We are currently processing FTGr from existing Carbon8 contracts and inputs into the facility are already nearing capacity,” he said.

“We have seen a very high level of interest in our pioneering technology from EfW facilities as well as strong demand for aggregate from local block makers.”

Carbon8’s first plant was opened at Brandon, Suffolk. All three sites will have a combined capacity in excess of 130,000 tonnes a year of FGTr. The firm’s strategy is to develop five sites nationally with a capacity of 250,000 tonnes a year.
