Environmentally friendly recycled energy system

Under the Okayama Prefecture Environmental Basic Plan and Misawa Homes’ Environmental Declaration, Misawa Homes introduced a biomass thermal utilization system that achieved zero emission of wooden waste with the automatic collection of wood chips, shaving and sawdust, and thermal recycling of the company’s prefabricated house manufacturing plant, and a PV power generation system with a view to reducing commercial energy use, CO2 emission, and waste discharge. The system will achieve annual reductions of the equivalent of 114.6 kiloliters of heavy oil, or 343 t-c/year of CO2 emission.

Thermal recycling of biomass waste

•	Automatic collection of sawdust and woodchips during timber processing
•	100% of the boiler fuel is biomass waste
•	Line design improved efficiency of sorted collection
•	Energy saving system using a motion sensitive automatic collector
•	Thermal utilization for air-conditioning and the wood panel hot-press process Amount of the discharged sawdust ····· 8,120 m³/year   (heavy oil equivalent) ····· 114.6 kiloliters/year   Sawdust collection capacity ····· 7.5 m³/minute   Boiler capacity ····· Maximum 4,800 kg/hour   Steam pressure ····· 1,764 Mpa

Power supply through the PV system

•	100% of the power for office lighting is supplied by the system
•	Antireflective measure
•	Installation design with a view to promoting the system’s spread in the region Solar cell capacity ····· 7.2kW (south side)     ····· 7.2kW (north side)   Solar cell type ····· Polycrystalline silicon
