Abstract
PURPOSE: A metal salt is added to waste to form metal soap and the foam is separated by the floating process, oil is mixed therewith and they are heated under pressure, then water is removed to recover the oil in high yield, whereby the waste is effectively utilized as fuel and compost.
CONSTITUTION: A salt, or hydroxide or oxide of metal is added to waste such as sludge, human and domestic animal waste, port sludge, building pit sludge and various kinds of sludge from waste water of organic products, by 1/30W1/100pts. pased on the organic substance of the waste by weight to form metal soap. Then, they are stirred to form foam, which is separated by the floating process. The foam is combined with oil and treated with heat under pressure, preferably at 0.5kg/cm2 and about vapor saturation temperature. Then, further it is heated under normal or reduced pressure to remove water and recover oil from the waste.
