What Milestone Environmental Services does

Milestone Environmental Services is a Houston-based environmental infrastructure company that provides oilfield waste management and carbon sequestration services to energy producers and industrial customers across the United States. The company's core offering is a proprietary slurry injection technology that permanently sequesters liquid and solid energy waste streams thousands of feet underground in secure geological formations, isolating waste from groundwater and preventing fugitive greenhouse gas emissions. The platform is supplemented by engineered carbon-sink landfills for drill cuttings and non-injectable solids, an industrial waste division (Milestone Industrial), and a carbon sequestration business unit (Milestone Carbon) pursuing Class VI permits in the Permian Basin and Louisiana. Milestone operates 15 strategically located facilities across Texas and New Mexico covering the Permian Basin (Delaware and Midland sub-basins), Eagle Ford, and Haynesville Shale, processing approximately one billion gallons of waste annually and having sequestered over 4 million tons of CO2e since 2014.

Milestone serves primarily exploration and production operators, with secondary customers including industrial waste producers, landowners, and policymakers. Revenue is generated through transaction-fee pricing for waste disposal services and subscription/recurring arrangements for carbon sequestration, with invoices issued on Net 30 terms against Milestone's standard price sheet. The company sells directly through its facility network, with no resellers or distributors, emphasizing 24/7 operational reliability and regulatory compliance with Texas RRC Chapter 4 regulations. The go-to-market is enterprise field sales targeting E&P customers in active production basins. Following its acquisition by SK Capital Partners in October 2023, Milestone operates as a privately held portfolio company with a five-member board and an expanded senior management team including a new CFO, VP of Sustainability, and VP of Industrial.
