Reaction product of Crude sludge and Calcium oxide. Crude sludge is the mixture of by-products of petroleum hydrocarbons refining (especially Total petroleum hydrocarbons, Polycyclic aromatic hydrocarbons, acid-refined heavy petroleum distillates). The Crude sludge is neutralised by calcium oxide in the ratio 80:20. The maturing process proceeds under ambient conditions and takes for at least 3 days. Subsequently, the reaction product is processed mechanically.
