The use of substitute fuels in the UK cement and lime
2014313&ensp·&enspThis report reviewed the use of substitute fuels (SFs), such as tyres, secondary liquid fuel and waste derived biofuels, in the UK cement and lime industries. The main purpose of this review was to develop a better understanding of the use of SFs in cement and lime kilns
Waste Profiling Secondary Materials Cadence
Cadence has 45 years of wastederived fuels experience. We were the first to use liquid industrial waste in cement kilns as an alternative energy source. Our leadership pioneered the use of alternative fuels and has been involved in developing this industry since the 1960s.

2020429&ensp·&enspThe use of scrap tires as a supplemental fuel in the United States Portland cement industry has increased significantly in the past six years. In 1990, there were two kilns using tirederived fuel (TDF), today 30 kilns use TDF. The outlook for continued and expanded use of TDF in the U.S. cement
Cement plant converts kilns for wastederived fuel (SRF)
Around 80,000 tonnes of wastederived fuel (SRF) per year is to be used to power two kilns at the "largest" cement plant in the UK. The Hope Works cement plant in Derbyshire will take in solid recovered fuel (SRF) from Lincolnshirebased waste firm Mid UK Recycling Ltd as well as councils in the surrounding area.

In modern cement kilns, most of the calcination (CaCO 3 (s) CaO(s) + CO 2) is carried out in the precalciner, and the process conditions there make it a good reactor for combustion of alternative fuels like RDF. However, most wastederived fuels have a poorer quality than coal, and this could negatively affect the process.
Fuels at Dunbar Cement Plant Dunbar, East Lothian
Waste derived fuels. Cement is a widely used construction material, and manufacturing it is an energy intensive process. We have been addressing this for several years at Dunbar, through replacing fossil fuels with waste derived fuels and reducing greenhouse gas emissions.
Cement Kiln Fuels Cemfuel Alternative Fuels for Cement
Previously this organic waste would be sent to landfill or it would require incineration, but it is now used to reduce the reliance of fossil fuels in the firing of cement kilns. This alternative cement kiln fuel is created by innovatively processing and blending organic wastes to a strict protocol.
