US: Regulators have scheduled a public hearing about Holcim's request to change the way it burns liquid wastes for fuel at its Holly Hill plant in South Carolina.

"We currently burn fuel in one place in the kiln and this permit will allow us to burn it further along in the process," said Holcim spokeswoman Robin DeCarlo. "It does not change the limits, but allows us more flexibility." Holcim burns a variety of hazardous materials as fuel in the place of fossil fuels. That includes waste solvents, oils, out-of-specification intermediates and products from various industries such as the paint, plastics and petroleum industries.

The public hearing is scheduled for 27 January 2015. The notice was released by the US Environmental Protection Agency and the S.C. Department of Health and Environmental Control. The plant is currently allowed to burn waste-derived fuel in its cement kiln. The permit will allow the plant to also treat and burn the fuel in the precalciner.

Holcim is also seeking a permit to construct a new stream channel designed to protect the plant from potential flooding. The project is awaiting approval by the US Army Corps of Engineers. DeCarlo said that the company expects to receive approval to proceed though is not certain when it will occur.

India: The Pollution Control Board has despatched 20,000t of effluent sludge generated by textile units in the SIPCOT Industrial Estate in Perundurai to cement plants in Ariyalur district in Tamil Nadu state for use as an alternative fuel. Local media reports that local cement producers have started accepting effluent sludge from the dying industry after the success of a trial run that indicated no variation in the strength and quality of cement. Following the first order demand for another 8000t has been expressed.

Australia: The Boral cement plant in Berrima, New South Wales, will receive a US$3.3m grant from the Environmental Trust as part of the NSW Environment Protection Authority's Waste Less, Recycle More initiative. The funding will be used to increase the use of waste derived fuels at the plant.

Executive general manager for Boral Cement Ross Harper said the achievement of the grant confirmed the potentially-important role that the New Berrima site could play in reducing the increasing impact of re-usable materials ending up in landfills.

"Since September, we have been informing our local stakeholders about the positive environmental and economic effects which can be obtained by replacing a portion of our coal consumption at Berrima with fuels derived from recovered and processed waste streams," said executive general manager for Boral Cement, Ross Harper.

Boral is currently preparing to submit planning applications which will seek approval for the use of wood waste-derived fuel and refuse-derived fuel in production at the Berrima plant. The site already holds an approval to use rubber tyre chips. Pending approvals, the site is looking to begin integration of the two fuels from the start of 2016 following construction of the new infrastructure.

Egypt: Suez Cement plans to spend US$84m in 2015 to convert its Helwan and Tora 2 cement plants to use coal. The move is a response to Egypt's on-going energy crisis.

The company reported a 40.5% rise year-on-year in third-quarter profit in November 2014 after it managed to pass on higher production costs to consumers. However, its nine month profit fell by 14.6% year-on-year due to severe energy shortages that forced the company to cut output by 40% so far in 2014. Suez Cement was one of the companies affected when the government cut natural gas supplies to factories in January 2014 and has had to import clinker at higher cost.
