Voice of America tells us how waste heat is being converted into energy. Sixty percent of all energy produced in the world today is being lost as wasted heat.  Now entrepreneurs are developing projects to covert much of that heat to electricity.The post features Gulf Coast Green Energy in the US state of Texas which hopes to capture some of the heat from the thousands of oil and gas wells in the state and use it to power homes. We also learn that heat-recycling technology can work with solar energy collectors, coal-fired power plants and internal combustion engines — almost any industrial process that produces waste heat.

hydrogenfuelnews reports on how a UK producer of industrial gases wants to turn waste into hydrogen. Air Products says the hydrogen gas that is produced through gasification technology will be used to power homes and vehicles with 50 MW annually. Air Products will build a new waste treatment facility in Teesside where transformation will take place using non-recyclable waste from landfills in the UK.

The latter source says this will be the world’s largest waste to energy plant.

The global consumption of ethanol and biodiesel is projected to reach 135 billion gallons by 2018 we learn from Biodiesel Magazine.

Science Daily informs us of a new breakthrough for generating electricity from wastewater. Engineers at Oregon State University have discovered microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will are able to power themselves, but will sell excess electricity to the grid. The new technology can produce 10 to 50 more times the electricity, per volume, than most other approaches using microbial fuel cells, and 100 times more electricity than some.

iafrica informs us of South Africa’s first municipal waste water biogas-to-energy project. WEC Projects, a firm which is implementing South Africa’s first biogas to power plant on a municipal waste water treatment works. Using an anaerobic digester, sewage sludge is converted into biogas to be used to run a turbine to generate electricity to power the waste water facility. By producing electricity this way, the plant lowers its costs by avoiding the necessity to purchase power from the national grid. Some suggest South Africa could save the costs of 30 MW of electricity annually by converting the 50 largest waste water treatment plants in the country to this technology.

Waste Management World says Boeing is going to refine cooking oil to biofuel in China. Boeing and the Commercial Aircraft Corporation of China are researching the use of waste cooking oil as a commercial aviation biofuel. The center aims to identify contaminants in gutter oil and processes that may treat and clean it for use as jet fuel. China annually consumes approximately 29 million tonnes of cooking oil, while its aviation system uses 20 million tonnes of jet fuel.

Indian Railways plans to build four plants to produce biodiesel, capable of producing 30 tons of fuel per day. CleanBiz Asia says the first two plants will be completed by 2013 and will be built Tondiarpet in Tamil Nadu state and Raipur in Chhattisgarh state. The locations of the other two plants are being finalized. Produced from waste oil, fatty acid and non-edible vegetable oil, Indian Railway’s bio-diesel will be blended with High-Speed Diesel oil for running its locomotives.

An advanced waste to biofuel facility is ready for production in the US state of Florida. Waste Management World reports Ineos New Planet BioEnergy will soon be producing advanced bioethanol made from non-food waste materials. The Indian River facility is the first commercial plant in the world using its feedstock-flexible BioEnergy technology – a combination of gasification and fermentation technology – to turn different types of waste materials – including municipal solid waste – into advanced biofuels and renewable power. The company is expected to start production this fall. It is expected to produce 8 million gallons (30 million litres) per year of advanced bioethanol and 6 MW of electricity from renewable biomass including local yard, vegetative and agricultural wastes. The plant will power 1400 homes in the Vero Beach community.

The Nation looks at Thailand’s need for biofuels. Diesel accounts for 55% of fuel consumed by the country’s transport sector and it is looking for a green fuel to replace this diesel. As biofuel from palm oil is affecting the volume of edible palm oil and its price, the focus now is on how to extract more biofuel from jatropha and how to ensure that the fuel will not damage diesel engines. Thailand mandates a compulsory mixture of 5% palm oil-based biofuel in diesel and now consumes 5.97 million litres of palm oil per day. The Kingdom has set a goal of alternative fuel comprising 20% of the country’s total energy consumption by 2021.

Waste Management World lets us know about a 2 MW biogas from palm oil waste project in Malaysia. Camco International will build a waste to biogas facility in Malaysia that will use waste from the palm oil industry to supply electricity to the national grid in 2013. The 2 MW biogas facility will be located at a palm oil mill in Palong, Pahang state, and will use anaerobic digestion to recover biogas containing methane from palm oil mill effluent. Malaysia is the world’s largest exporter of palm oil products and has approximately 4 million hectares of land under oil palm plantation.

A dairy farm in Plymouth, England is producing electricity reports this is Plymouth. Last year the farm generated 3.5 MW of electricity (enough to power 175 million 20 watt light bulbs for 1 hour) using 12,000 tonnes of food waste. The farm uses anaerobic digestion to convert its organic waste into methane gas to power a generator. The electricity is used on the farm and sold to the National Grid while the waste heat from the process is extracted and used at the factory.

A farm in the US state of Indiana intends to use duck offal and corn silage to produce electricity and heat reports the Post-Tribune.

eurasia review labels woodchips the joker in the renewable energy game while science 2.0 calls them the wildcard of renewable energy. “One renewable energy source is easily available as waste from from construction, agriculture, landscaping, logging and sawmills. And it’s already used in domestic and district-level heating systems. It is the main solid biomass fuel source used for combined heat and power production, known as co-generation, a definite advantage as an energy source.”
