In oil refinery industry, processing residues known as Petroleum Refinery Sludges (PRS), are currently classified as hazardous waste. Around 1 million tons of PRS are produced each year in Europe.

Cost-effective treatment and proper disposal of PRS pose considerable challenges to the industry. The DIANA project aims at proposing an innovative process to turn PRS into a Valorised Sludge Mixture (VSMà-) that can, in turn, be processed into added value Engineered Soil, to be applied in landfill construction and restoration.
