Actividades realizadas o en vías de realización The three companies jointly announced, in May 2010, that they successfully developed a practical urban biogas system, and that this system was adopted in the Tower Pavilion of Abenobashi Terminal Building in Osaka City. The system, which is being contructed now and opens in 2014, will generate methane gas making use of waste food and kitchen wastewater etc. that are discharged from hotels, restaurants and department stores etc. of the complex terminal building. The methane gas is used as fuel for gas engines and boilers to generate electricity and heat.

Resultados y repercusiones This system’s big merit is that waste food discharged from urban high-rise buildings located in the city center can be reused as energy on the spot. The system produces biogas by fermenting raw garbage plus kitchen wastewater and sludge from recycled wastewater treatment systems in a methane fermentation tank. This permits a building operator to treat these substances inside the building, ending the need to send them to an outside plant for treatment. In the future, Takenaka Corporation will propose the use of this system in complex buildings and redevelopment projects in the centers of cities.
