A Tarmac Derbyshire cement kiln to be powered by rubbish pellets

A Humberside firm, Eco-Power Environmental, has agreed a deal to provide solid recovered fuel pellets to Tarmac's Tunstead cement kiln in Derbyshire.

Solid recovered fuels (SRF) pellets are manufactured using the non-recyclable residues from dry mixed recycling (DMR) facilities and provide an alternative to traditional fossil fuels. They are used by a range of energy-intensive industries such as cement & lime, steel and the power sector.

Eco-Power Fuels says its pellets can be customised and provide  :

· Biomass up to 50%

· High calorific value generating over 20MJ/kg

· Low Chlorine content <0.5%

· Low ash content

· Ability to be co-dosed with fossil fuels using existing equipment

Commenting on the deal, Eco-Power Environmental group commercial director, Louis Calders, said: "Tarmac has been a pioneer in the use of sustainable fuels, and we are excited by the results we are seeing from the kiln.

"The ease with which pellets can be transported, coupled with their composition and burn characteristics is resulting in high levels of demand from both the UK and Europe. We look forward to ramping up production capability and have a further 3 facilities planned in the UK."

"We got the opportunity of trialling the SRF pellets early in the year as a replacement for woodchip. 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 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."

Tarmac states that it is committed to the use of waste-derived fuels, especially those that have a high biomass content. It views these fuels as reducing CO2 emissions, conserving natural resources and helping to reduce the amount of waste that goes to landfill. In 2019, more than 30% of the heat input to its cement kilns was produced from waste-derived fuels.
