The Economic Times reports that India’s largest cement-maker plans to substitute 5 % of its annual coal requirement with waste generated by cities and industries. Over the next three years ACC intends to eliminate 5 million tonnes of coal per year buy burning waste (primarily plastic) at its plants. Plastic has higher calorific value, or heat content, than coal. The company is also working on disposal of industrial wastes and then using them as fuels at its plants.

CleanBiz Asia tells us that a Thai coal plant is being retrofitted for biomass generation.  The aging coal-fired power plant in Thailand is being converted to operate on waste wood such as eucalyptus bark. It will provide electricity and steam to Thailand’s largest bioethanol plant which is currently being built. The new bioethanol plant, in Nakorn Ratchasima, is expected to produce 1 million litres of bioethanol a day.

Biofuels Digest says that in the US state of Mississippi a regional landfill will capture methane and use it to produce electricity.  The power will be sold to the Tennessee Valley Authority.

A waste management firm in Somerset, England will convert food and organic waste into electricity using anaerobic digestion (AD).  Waste Management World tells us that Viridor’s first AD plant at its landfill site will produce 1 MW of surplus electricity for export to the UK National Grid, with the possibility of producing clean gas for injection into the gas grid also under review.

Waste Management World also writes that a combined heat and power AD facility that will process agricultural waste is to be constructed on a farm in Hereford, England.  The system will have the capacity to process 700 tonnes of poultry litter and 1000 tonnes of cattle slurry, mixed with 3000 tonnes of maize silage each year and turn it into 250 kW of electricity and 200 kW of heat. The electricity will power the farm’s poultry houses and AD system, with a 90% surplus sold to the UK National Grid. The captured waste heat will warm the chicken houses – displacing fuel oil and propane gas.

A “cutting-edge” meat powered biogas plant has opened in the south east of Hungary we learn from Renewable Energy Magazine. The waste recycling plant in Szarvas, with a peak power output of around 4 MW, was built in twelve months and can process over 90,000 tonnes of waste meat and other organic residues per annum. The plant uses renewable raw materials and organic waste from the region to produce hot water and electricity through cogeneration.  It is capable of processing more than 40,000 tonnes a year in waste from meat production in the region and another 53,000 tonnes of residual waste (slurry and manure) from neighbouring livestock and meat processing farms. In addition, around 18,000 tonnes of agricultural substrate is used as feedstock for the plant, which produces in excess of 12.5 million cubic meters of biogas. The electricity can supply 18,000 inhabitants, which is around the size of a city such as Szarvas.  The biogas is used as a substitute for 1 million cubic metres of natural gas a year.
