Ecoslops S.A. (ALESA.PA) develops and operates innovative micro-refining technologies to recycle hydrocarbon residues, including maritime slops, sludges, land-based industrial oil residues, and used lube oil, into second-generation commercial products such as naphtha, gasoline, diesel (gasoil), heavy fuel oil, and light bitumen; the company provides integrated port services encompassing collection, storage, water treatment, and waste management compliant with MARPOL Annexes I and V; it offers the compact, modular Scarabox unit for localized recycling of up to 7,000 tons of dehydrated residues annually, alongside its larger P2R (Petroleum Residue Recycling) process handling over 30,000 tons per year with more than 98% regeneration rates and reduced CO2 emissions compared to conventional refining. Founded in 2009 and headquartered in Paris, France, Ecoslops primarily operates its flagship industrial-scale recycling facility in the Port of Sines, Portugal, under a sub-concession agreement expiring in 2027 with renewal discussions underway with GALP subsidiary CLT; the company targets port infrastructures, waste collectors, shipowners, oil and gas firms, and institutional actors across Europe and emerging markets. Recent major changes include the February 2024 completion of the divestiture of its 75% stake in Ecoslops Provence to TotalEnergies for €8 million plus debt assumption, significantly reducing group net debt from €23.2 million to €10.3 million and enabling refocus on the profitable Sines operations generating approximately €2.2 million annual EBITDA and Scarabox commercialization; in 2024, Ecoslops secured ISCC Plus certification for Sines products, advanced partnerships with Parlym for joint ventures (80%/20%) in Ivory Coast—including a letter of intent with national refinery SIR—and Cameroon projects via Valtech Energy where it plans to increase its stake to 49%, alongside ongoing productivity optimizations, supply securitization, and European Investment Bank debt renegotiation.
