GEN - Zero emissions and Recycling
operation results
Verification test (research and development): Commissioned project research of Agriculture, Forestry and Fisheries Research Council "Agriculture, Forestry and Fisheries biocycle research"
Treated wastewater: Concentration of digestive fluid which is after methane fermentation.(made into liquid fertilizer)
Bfore introduction: Used directly for agriculture, not be concentrated.
After introduction: Concentrated liquid became one of the options as liquid fertilizer. Low concentration recovery water is recycled in the plant as general service water.
Type: GEN Type 500 (Special type)
Date: February, 2007
Introduction background: Applied to one of biomass multilevel use. Special type is used because it is difficult to get optimal concentrated ratio stably by standard type.
Electric electronic part manufacture
Treated wastewater: Soluble cutting oil
Bfore introduction: Disposed total amount as industrial waste
After introduction: Recovery water is disposed to sewage
Type: GEN Type 25
Date: March,2005
Introduction effect: Reduction of industrial waste disposal cost
Photovoltaic component manufacture
Treated wastewater: Wire saw waste liquid for silicon cut
Bfore introduction: Dispose total amount as industrial waste
After introduction: Unit washing water was reduced and flowed to drainage treatment. Solvent was recycled for processing waste slurry.
Type: GEN Type 600 (Special type)
Date: September, 2005
Introduction effect: Reduction of the cast for industrial waste disposal
Paper bag manufacture (Printing /Bag-making )
Treated wastewater: Ink waste liquid / Glue waste liquid
Bfore introduction: Dispose total amount as industrial waste
After introduction: Recovery water is treated secondly and flowed to sewage. Residual waste is disposed as industrial waste.
Type: GEN Type 300 at the time of introduction, GEN Type 450 now.
Date: GEN Type 300(May, 2007)＋ Type 150 added (My, 2008)
Introduction effect: Reduction of the cast for industrial waste disposal
Silica product manufacture
Category of industry: Silica product manufacture
Treated wastewater: R-123 alternate CFC and wastewater mixed with silica flour
Bfore introduction: Existing distillation facility was used. (Recycling R-123 alternate CFC)
After introduction: Realization of higher recovery rate and less recovery cost than existing distillation facility.
Type: GEN 100 (Special type)
Date: December, 2007
Introduction effect: High concentration became possible, which used to be impossible with simple distillation facility.
Printed board manufacture
Category of industry: Printed board manufacture
Treated wastewater: Dry film resist separation wastewater
Bfore introduction: Dispose total amount as industrial waste
After introduction: Recovery water is flowed to integrated drainage treatment institution and only residual waste is disposed as industrial waste.
Type: GEN Type 250 x 2 unit
Date: December, 2005 / December, 2006
Introduction effect: Reducing industrial waste by 85 percent. It used to cost a lot for waste disposal because raw water includes much resin content.
Heavy equipment parts manufacture
Category of industry: Heavy equipment parts manufacture
Treated wastewater: Soluble cutting oil
Bfore introduction: Dispose total amount as industrial waste
After introduction: Recycle recovery water as dilution water of soluble cutting oil
Type: GEN(ZERO) Type 25
Date: December,2005
Introduction effect: Reducing wastewater by 90 percent and rycycling recovery water as dilution water for raw soluble cutting oil.
