P2R Process - Ecoslops is the cleantech that brings oil into the circular economy by upcycling oily waste into new fuels and bitumen conform to international standards.

Various oily residues are produced (pipeline cleaning, contaminates, tank bottoms), but most of them come from ships, which ensure 90% of the world merchandise transportation. There is a strict regulatory framework (IMO, MarPol) but its implementation is difficult and costly. To comply with these rules, oily waste producers most often have to pay to have their waste collected and/or treated. It unfortunately still leads to illegal dumping and discharge at sea or in rivers. Buying back these oily wastes is an incentive for producers to get them collected and treated, and helps the collectors to be sustainable. After the water and sediment have been removed, the Petroleum Residue Recycling Unit (P2R unit) then upcycle these residues into several types of new commercial products, compliant with international standards. The distillation scheme, specifically designed in order to treat slops which are variables by nature, involves atmospheric and vacuum distillation in successive steps.

Key features

  • The P2R can offer worldwide port infrastructures, waste collectors (maritime and terrestrial) and ship-owners a cost-effective, environmentally friendly solution that complies with international and EU regulations regarding the treatment of oily residue
  • The P2R process can divide greenhouse gas emissions by three compared to the traditional process based on crude oil extraction, and helps preserve the raw hydrocarbon material stock.
  • Thanks to a financial incentive for waste generators and/or collectors, the process also allows to preserve oceans and rivers


  • Ecoslops' solution financially benefits vessels and oily waste collectors. Its installation sustains the local collection system, creates new qualified jobs, and enhances local economy.
