Greenleaf Environmental Services turns oilfield waste streams — wastewater, tank bottoms, drilling mud, cuttings — into treated, permitted, beneficial-reuse products, all from one Mesa County facility.
Greenleaf sits 7 miles from De Beque, CO — a central location that keeps haul distances short for operators across the basin. With trucking and disposal both considered, that makes Greenleaf the most cost-effective wastewater disposal option in the Piceance Basin and surrounding area. Between treatment, evaporation ponds, and the injection well, the facility takes on wastewater at scale without operators needing a second disposal partner.
5 active evaporation ponds totaling 470,953 barrels of space, plus an injection well built for 5,000 barrels/day of injection capacity. Greenleaf's water treatment system restores wastewater to a useable standard before it's discharged to a pond or injected — removing 95–99% of organics and solids, 99% of heavy metals, 99% of bacteria, and 25% of monovalent cations and anions.
Raw intake vs. treated output, side by side
Tank bottoms, drilling mud, wet cuttings, and treatment sludges are dosed with de-mulsification agents to recover oil, then pumped to a mixing tank for separation. Recovered water and oil go to the tank farm for treatment; remaining solids are pressed, dried, and moved to solids impoundments for further treatment.
Solids placed in certified Section 3 impoundments receive chemical and biological treatment — a demulsifying chemical process paired with petroleum-feeding bacteria — converting waste to carbon dioxide and water aerobically, in days rather than the years conventional land farming takes. The process handles oil concentrations as high as 30%.
Greenleaf is pursuing permitted beneficial-reuse authorizations across every waste stream it handles — road spray for dust suppression and de-icing, light and heavy brines, and clean water — working toward a future where nothing leaves the facility as waste.
Greenleaf's long-term direction is converting everything delivered to the facility into a permitted, reusable product instead of a disposed one. That work is already underway across three tracks:
The plasma treatment process Greenleaf is evaluating in partnership testing — organic waste in, syngas and neutralized aggregate out.
Greenleaf serves waste disposal needs across the Piceance Basin and surrounding area, accepting both E&P and non-E&P wastewater and solids. The objective is simple: limit disposal liability through strict compliance with all regulations — and through the reuse and reclassification of the wastes themselves. Every waste stream is treated to an industrial or residential reuse standard before it's placed in an evaporation pond, injected, or moved to a certified Section 3 impoundment.
None of this exists on the site today — a look at what becomes possible once the refresh is live.
