UK: CRH subsidiary Tarmac has awarded a contract for the supply of solid recovered fuel (SRF) pellets for its Tunstead cement plant to Eco-Power Environmental. The supplier says that the fuel will come from its 125,000t/yr Humberside SRF pellet plant in Melton, East Riding of Yorkshire. It has spent Euro17m in recent upgrades to the plant. Its pellets offer up to 50% biomass content, calorific value in excess of 20MJ/kg, less than 0.5% chlorine, low ash content and the ability to be co-dosed with fossil fuels using existing equipment.

Tarmac Tunstead plant manager Chris Bradbury said “Reducing CO₂ at Tunstead is one of the team's top priorities and working closely with our colleagues in Sapphire we have made good progress with sustainable waste-derived fuels throughout 2020 and hope to go further in 2021.” He continued, “We got the opportunity of trialling the SRF pellets early in the year as a replacement for woodchips. The trial went well with only a few modifications required for the inside of the storage silo and feed out system. Once the moderations were completed, we extended the trial, which had great results. In June 2020 we then went on to continuous usage and from the start the pellets have proved to be a very stable fuel. These have been one of the main contributors to the continuous high waste-derived fuel substitution rate for fossil fuels from June to the end of the year.”

UK: CRH companies Tarmac and Sapphire Energy Recovery have installed a waste-derived fuel processing unit at the Tunstead cement plant in Derbyshire. The unit will produce 'specialised fuel,' a type of solid recovered fuel (SRF) for the cement plant.

"Using waste-derived fuels is well established in the industry but having our own fuel processing plant on site is a first for us. This project from initial concept to actual results, has been a fantastic collaborative experience between Sapphire's commercial, technical, operational and environmental teams, with strong support from the Tarmac kiln and permitting teams,” said David Wilson, Sapphire’s commercial manager. He added that the companies can adjust the blend and amount they use to suit the production process.

UK: Tarmac has ordered a solid recovered fuel (SRF) handling system from Saxlund International to increase the capability to utilise alternative fuels at its Dunbar integrated cement plant. The SRF system will be installed in the second half of 2019. It is designed for the reception of trucks and storage of fuel in two bunkers. The new system includes processing of fuel to remove ferrous and oversize particles before weighing and dosing into a pneumatic conveying system for kiln injection. The Dunbar plant will use SRF supplied by Hamilton - Solid Recovered Fuel.

“We are delighted to be involved in the development of this new SRF facility at the Dunbar Cement works. The overall system for the reception, storage and conveying of SRF fuel will help to ensure a highly resilient and robust solution for our client,” said Mark Neal, sales manager at Saxlund International.
