Mitsui Engineeringand Shipbuilding will establish a joint venture to market biogas generation equipment with a Chinese company in Chongqing of China with a capital of 600 million yen on a 50:50 basis. Mitsui’s technology smashes food residues after eliminating water and oil and ferments them, and subsequently recovers methane gas for power generation. Water will be discharged after treatment, and sludge will be dried and used as compost. The company used to focus on the Japanese domestic market, but it decided to expand the business to China because food residues are growing fast in China as it grows richer. The system costs between 500 million to 1,000 million yen each.
JEF Engineering got an order for a biogas generation plant scheduled for operation in 2013 from Shinyu of China. The plant has a capacity to treat 200 tons of food residues collected from restaurants per day. Hitachi Zosen is planning to establish a base in Hanoi of Vietnam to market its generation plant that uses waste heat recovered from burning municipal waste. Refuse disposal generation does not emit carbon dioxide. A research firm predicts that the world market of refuse disposal generation will grow from 25 billion yen in 2010 to 73 billion yen in 2015.
A health center that utilizes residual heat produced by refuse disposal. Japanese engineering companies started to expand business to Asian countries including China and Vietnam where food residues are growing fast as they grow richer to market their latest refuse disposal generation technology.
