Switching from high carbon-intensive fuels to less carbon-intensive fuels or replacing the conventional fuels with alternative fuels such as biomass and waste derived fuels may result in a significant reduction in

Lafarge cement plant reduced CO2 with biomass

"We (the cement industry) use a lot of fuel," Cumming said. "Not nearly as much as the power industry but we're up there, and the reason we need so much energy is because we're heating rock up to almost a semi-molten level, about 1,400 to 1,500 degrees Celsius (2,550 to 2,730 degrees Fahrenheit)." A typical kiln is cylinder shaped, about 18 to

Aug 09, 2011 The use of alternative fuels in cement manufacture is also ecologically beneficial, for two reasons: the conservation of non-renewable resources, and the reduction of waste disposal requirements. The use of alternative fuels in European cement kilns saves fossil fuels equivalent to 2.5 million tonnes of coal per year (Cembureau, 1999).

In March 2014, following detailed consultation with the cement industry, the environmental regulators responsible for monitoring and controlling the use of waste derived fuels in the UK Scottish Environment Protection Agency, Environment Agency, Natural Resources Wales, and Northern Ireland Environment Agency introduced a new Code of Practice governing the way waste is used in cement kilns.

Cement Analysis IEA

Fossil fuels continue to provide the majority of energy in the cement sector, with bioenergy and biomass-based wastes accounting for only 3% of thermal energy used in 2018. In the SDS, the thermal energy intensity of clinker production declines by 0.7% per year to a global average of 3.1 GJ/t, and the electricity intensity of cement production

Can solar kilns be a viable option in the cement sector?

Oct 02, 2020 The concept of solar powered kilns has proved difficult to scale up and Jan Baeyens, Solpart's Managing Director, believes a fully solar-powered cement plant is doubtful, but it is tangible that merging solar energy with alternative fuels such as biomass will be possible.

Alternative Fuels Cembureau

In Europe, the cement industry has replaced a large part of its traditional fuel sources with biomass or waste. From a technical point of view, much higher substitution rates are possible, with some plants using up to 80% alternative fuels 1.. Apart from direct effects of replacing carbon-intensive fossil fuels with lower-carbon-intensity of alternative fuels, there can also be indirect benefits.

Use of MRF residue as alternative fuel in cement production

The energy use and emissions at each step is tracked for the two cases: (1) The Reference Case, where MRF residue is disposed of in a landfill and the cement kiln uses coal as its fuel source, and (2) The SRF Case, in which MRF residue is processed into SRF and used to offset some portion of coal use at the cement kiln.
