What Re Sustainability does

Re Sustainability Limited (formerly Ramky Enviro Engineers Limited) is a Hyderabad-headquartered, integrated environmental services provider founded in 1994 and majority-owned by KKR since August 2018, when the PE firm acquired a 60% stake for $530 million. The company manages approximately 10 million tons of waste annually across 23 Indian states and roughly 10 countries through a portfolio of hazardous industrial waste, biomedical waste, municipal solid waste, recycling, waste-to-energy, and water/wastewater treatment services, alongside environmental consultancy and EPR compliance offerings.

Its core technical platform rests on capital-intensive assets and proprietary processes, including a 19.8 MW waste-to-energy plant at Jawaharnagar, Hyderabad consuming 1,200 tonnes per day of refuse-derived fuel (with an additional 24 MW under development at the same site and 15 MW planned at Dindigul); a 30,000-vehicle-per-year End-of-Life Vehicle dismantling facility at Jhajjar under the Re Carma brand; Plascon and Indirect Thermal Desorption PCB destruction capacity of 330 tons/year at Bhilai; a Gulf-first MARPOL reception facility at Sohar, Oman processing 50,000 cubic metres annually; and IoT-enabled electric waste collection fleets (e.g., 850 vehicles across 150 GHMC wards and 115.5 sq km in Greater Chennai Corporation). Certifications across ISO 9001/14001/45001, GRS, and Ocean Bound Plastic standards underpin regulatory credibility.

Re Sustainability generates revenue through long-term managed services contracts with municipal corporations, industrial manufacturers (Tata, Adani, Bhilai Steel Plant), healthcare facilities, and SEZs, supplemented by transaction-based revenue from recycling material sales, WTE electricity off-take, EPR credit fees, and re-refining. Distribution is a mix of direct enterprise sales, government tenders, strategic JVs (Indian Oil for used oil; Khimji Ramdas and Nature Group in Oman), and conglomerate partnerships. The company employs 10,000+ people and is currently in an NCLT-approved demerger ahead of a 2026 KKR exit process that has drawn interest from TPG, CPPIB, Veolia, Macquarie, Bain, Carlyle, and Blackstone at a valuation exceeding $2 billion.
