Sita UK has started the commission process for a second facility turning residual waste into solid recovered fuel (SRF) to power cement manufacturing.
The plant, located at Malpass Farm in Rugby, will undergo a series of tests before starting full-scale production in June. The SRF, trademarked as Climafuel, will be used to power an adjacent cement kiln operated by building materials supplier Cemex.
Sita has already been operating a similar facility at Landor Street in Birmingham. Once the new plant is fully operational, total production of SRF will be around 250,000 tonnes a year, said Andy Hill, head of alternative fuels at Sita UK.
“The residual waste material that will be delivered to this facility would have gone to landfill but, instead, we are going to take out anything which can be recycled and then turn what’s left into a replacement fossil fuel – made to the exacting standards expected by our partners at Cemex,” he added.
The plant’s feedstock is residual commercial and industrial waste. Once the material is received on-site, metals, plastics and paper are extracted for recycling. Materials with a high chlorine content, which could damage the kiln, are also removed.
The remaining material is sifted, shredded, blended and analysed using infrared technology to ensure quality standards are met.
Sita said it has invested in other SRF manufacturing facilities at the Port of Tilbury in Essex. They are currently under construction.
