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.
UK/Portugal: N+P Group, a Netherlands-based waste processing firm, has landed a contract to supply 0.7Mt of solid recovered fuel (SRF) from UK recycling companies to cement plants operated by the Portuguese companies Secil and Cimpor. This follows N+P's first shipment of SRF from Grimsby, Lincolnshire to Portugal earlier in 2014. A 'minor part' of the contract will be satisfied by using waste from France and Italy.
Chairman Karel Jennissen said, "In recent years we have invested millions in developing the UK market to provide end users of our SRF sustainable supply concept. We put a lot of effort towards optimising quality levels of SRF in the UK market and have invested in the development of sustainable logistics chains. Now N+P has several port sites at strategic locations and the possibility to use a large number of sea containers."
Hungary: Lafarge Cement Magyarorszag has inaugurated a Euro2.28m alternative fuel warehouse at its cement plant in Kiralyegyhaza in the south-west of Hungary. The warehouse will store waste rubber and plastic, as well as industrial and farm waste.

PPC to use waste tyres as alternative fuels
21 November 2014South Africa: PPC has concluded an agreement to source waste tyres from the Recycling and Economic Development Initiative of South Africa (Redisa) for use at its De Hoek cement plant in Piketburg, Westerm Cape. PPC is also investigating the possibility of using waste tyres in some of its other plants, according to Azola Lowan, the executive for investor relations and strategy.
Redisa is the only waste tyre management plan approved by the Department of Water and Environmental Affairs and is involved in the collection and processing of waste tyres. Lowan said that the use of the waste tyres in the kilns at the De Hoek plant would be introduced from the middle of 2015 and indications were that the tyres could replace 10% of its coal usage. Lowan also confirmed there was a cost benefit from using the waste tyres instead of coal and a carbon advantage because of the reduced use of coal. Some investment was required in the feeder system to use waste tyres, which meant this initiative would only generate a return over a few years.
Lowan stressed this was one of several environmental and alternative energy initiatives being undertaken by PPC to ensure that PPC is compliant with environmental legislation and regulations by 2020. PPC has already commissioned the use of carbonaceous spent pot liner, a waste material from the aluminium industry, at its Dwaalboom cement plant in Limpopo. "We basically get paid to use that product and again it replaces about 5% of the coal," Lowan said. She added that PPC was also doing a feasibility study on a waste heat recovery (WHR) system at its Dwaalboom plant. PPC also has an agreement with Innowind, which is constructing a 60MW wind farm in the Eastern Cape to provide electricity to PPC's Grassridge quarry.
Colombia: Cementos Argos plans to use more than 26,000t/yr of used tyres generated in the Valle de Aburra region as fuel for its cement plant. Tyres could be incorporated in Cementos Argos processes by the end of 2014 or the beginning of 2015. Executives have commented that one of the main obstacles is the collection of used tyres.
eRex to Invest US$164m in biomass power plant at Taiheyo Cement
16 September 2014Japan: eRex Inc, a power generation company, has agreed to invest US$159m in a biomass power project situated in the premises of Taiheyo Cement plant in Oita Prefecture, Japan. The total installed capacity of the power plant will be 50MW, sufficient to supply 100,000 households. The investment/MW will be US$3.18m. The power plant will use palm shells, a by-product of palm oil production in Indonesia and elsewhere, as its primary fuel. The company will set up a separate storage facility in Oita to hold 100,000t of palm shells. The power plant is expected to be operational in 2016.
Holcim Romania completes Euro6m waste processing plant expansion
11 September 2014Romania: Holcim has completed the extension of its waste co-processing platform in Campulung, Arges County, following a Euro6m investment that was co-funded by the European Union (EU).
The project was implemented throughout 20 months via ecovalor, a Holcim division that specialises in waste management. Of the total Euro6m investment, Euro1.6m came from EU funds under the economic competitiveness programme. Holcim Romania introduced waste co-processing in its cement plants in 2003 and has invested Euro32m in waste processing.
Semen Indonesia wins energy award for biomass use
20 August 2014Indonesia: Three state cement manufacturers, PT Semen Indonesia, PT Semen Padang and PT Semen Tonasa, have been using biomass as alternative energy source to replace coal and reduce electrical energy in stages.
Semen Indonesia has won an energy award from the Energy and Mineral Resources Ministry in recognition of its efforts to diversify energy needs by taking advantage of biomass renewable energy as an alternative fuel and to play an active role in developing new technology and innovations in the energy sector.
"The award has confirmed the commitment of Semen Indonesia to implementing a concept of sustainable business," said Semen Indonesia president director Dwi Soetjipto. He added that the cement industry is an energy-intensive industry, which also consumed coal as non-renewable energy. "By taking advantage of biomass, double goals could be achieved: first, conserving the environment and second, increasing the efficiency of operating costs, which will eventually increase in corporate profitability."
The use of biomass has stimulated local economy because it had been obtained from areas around the plants, including Tuban, Lamongan and Bojonegoro Districts in East Java, as well as Rembang District in Central Java.
"The use of biomass has also helped to reduce greenhouse gas emissions so that the impact of global warming can be minimised," said Soetjipto. Semen Indonesia has always increased its use of biomass as an alternative fuel to reduce coal consumption every year, Soetjipto added.
Egypt: Sinai Cement Company (SCC) has contracted Danish engineering company FLSmidth to provide the equipment for it to start using coal. SCC added that it would also partner with local contractors and suppliers to equip the factory to use coal as an alternative fuel source to natural gas and Mazut fuel oil.
The industrial sector, which is represented by the Federation of Egyptian Industries, has shown signs of accepting recent increases in automotive petroleum products prices, including fuel, diesel and natural gas. The sector said that it would bear the cost of the energy price increases taking into account the current economic situation 'that doesn't allow for any alternative.'
Following the fuel price hike announcement, the government has raised gas prices for cement plants to US$8 per million British Thermal Units (BTUs) compared to US$6 previously. The price of fuel oil increased from US$209/t to US$315/t.
Despite the Ministry of Environment's opposition, the interim government approved the industrial use of coal as an alternative energy source in April 2014. The move came to address the energy shortage, pending the endorsement of the Environmental Impact Assessment. After issuing the decision, the government said that it would impose a tax on coal usage, while also amending laws and tightening penalties for violating environmental standards and regulations.
Minister of Industry Mounir Fakhry Abdel Nour said that importing coal would not start until the environmental standards and regulations for the industrial use of coal have been finalised and ratified. However, cement plants have already started taking steps towards this. In a bid to shift to coal usage, the Arabian Cement Company commenced testing coal in June 2014 in thermal power generation. It aims to shift to this energy source for 50% of its needs. Suez Cement also recently announced plans to invest US$14.9m to convert two of its four cement plants to use coal. The conversion process for each plant will cost around US$21m.
