Kawasaki Heavy Industries plans to put an integrated plant for the treatment of municipal waste and sewage into practical application in 2013. Exhaust heat and electric energy created by the refuse incinerator will be used to dry sewage sludge and purify sewage. The new kind of plant is made up of such equipment as refuse incinerator, exhaust heat generation equipment, and sewage recycling equipment. It will be built alongside a cement plant, and it generates using the exhaust heat created in the cement plant to operate the sewage disposal facilities. It costs less than half the amount needed to build a waste disposal facility and sewage disposal facility independently. Refuse incineration ashes will be used as a cement material. The company will operate demonstration equipment in 2011 to collect data of the collection efficiency of exhaust heat, and wishes to get the first order in 2013. It will cost 5-10 billion yen to build this kind of plant to treat the waste and sewage produced by a city with a population of 100,000 people. With the population concentration in the urban area, cities in China and Southeast countries face rapidly increasing amount of waste and sewage and demand for the waste treatment plan is growing rapidly, too. The market of the waste treatment business in China and Southeast countries is estimated at about 5,000 billion yen (US$\60 billion) in 2020, three times as big as the estimate for 2010.
