PT. Sekar Bengawan in Karanganyar Regency. Central Java is a printing textile industry which produces 1,25 m³ of kerosene waste per day. Based on technical test, the characteristic of the kerosene waste are as follows, 42,772 MJ/kg of calorific value, 0, 08359 mg/m³ of SO₂ emision, and 0,13518 mg/m³ of NO₂ emision. The kerosene waste can be used as fuel with the ratio of time length, volume of soot, and weight of soot is 1,72 ; 1,6 ; and 3,1 times bigger than kerosene. Based on exposure assesment of   SO₂  and of NO₂, Hazard index value for adult woman is 0,412; adult man is 0,272 ; child 6-12 years is 0,27;. and child  2-6 years is 0.2725. With hazard index less than one, so kerosene waste will not generate health impact. Based on these data, kerosene waste can be reused and resold to the market. The target market segments are households and street vendors.
