Drilling-waste bioremediation

On-site microbial and enzymatic treatment of oil-based drill cuttings and drilling mud that degrades residual hydrocarbons and polymers before land disposal, cutting landfill volume and disposal cost for oil and gas operators — sold by specialist environmental-services firms (EnviroZyme, Enviro Resources, GEP Zymes, Keneco Environmental) rather than performed in-house by drilling companies.
