Biogas

Clean power project developer Camco is to develop a 2-MW biogas project at a palm oil mill in Malaysia, with completion expected in early 2013.

A project in Indonesia, funded by the Renewable Energy and Energy Efficiency Partnership (REEEP), aims to transform wastewater from tofu production into biogas, which will create both environmental benefits and increase the use of renewable energy by the industry and surrounding communities. Tofu production is highly water intensive. For example, about 60-kg of soybeans and 2,700 liters of water are required to produce 80-kg of tofu. More that 95 percent of the water ends up as wastewater containing reductive sugar, sucrose, starch and volatile acid that, if left untreated, pollutes both soil and air, releasing noxious odour and greenhouse gas.

China's biggest egg producer said Friday it will cooperate with a major US meat supplier to establish a bio-fuel company in the United States with a total investment of USD1.8 billion, according to a report in Xinhua.

With the steady growth of Asian cities more and more waste is being produced and, if not treated correctly, will become a huge environmental issue.

A farmer in China is partnering with scientists to promote his design for low-carbon households. His concept, developed over the past 30 years on his farm in northeast China, is a combination of existing green technologies. Now the country's scientists want to scale up the design to make it affordable.
