Southern Kyushu in Japan is a centre of alcoholic beverage production. The distillery waste is now dumped into the sea at a disposal cost to the distilleries at 3000 Yen per m3. Research studies at Miyazaki University and Fujita Construction Co., using dissolved air and anaerobic digestion in submerged rotating biological contactor (RBC) may provide an answer to sea-water pollution around Kyushu. With 24 hours detention at 37 celcius, 90 % of TOC is converted to gases (65 % is methane). More information: see Water Quality International. No.4. 1988.
