In Taiwan, the wastewater of kitchen flows down into the sewage treatment system. Fats, oils, and grease (FOG) are collected in the grease interceptors. The FOG amount of restaurants is about 300,000 tons every year. The FOG is treated by bury or incinerates. However the processing cost of bury or incinerates is too high, the FOG is poured into soil or river. Our company, Ministry of Economic Affairs technique SBIR and Tainan District Agricultural Improvement Station cooperate and carry on the plan- the FOG transform into compost by microbe technique. This study integrates the way of microbe, bio-nutrients and organic formula to create good living environment for transforming FOG into compost. The product of primary fermentation is applied to wastewater treatment and the FOG is emulsified and reduced. The product of secondary fermentation is applied to plant melons and the melons are growing well. We successfully develop the technique of the FOG processing by microbe and solve the FOG pollution of soil and river.
