What Envirachem does
RSI Environmental Services (operating as RSI) is a B2B environmental services firm headquartered in Oak Ridge, Tennessee, and the dedicated environmental services group of ASRC Industrial. The company delivers nine interconnected service lines spanning the full lifecycle of industrial and nuclear facility management: Asset Management, Decontamination/Decommissioning/Demolition, Environmental Services, Operations & Maintenance, Project Delivery, Radiological Services, Regulatory Services, Renewable Energy, and Waste Management. Its primary customer base is federal — specifically the U.S. Department of Energy and the National Nuclear Security Administration — with a secondary industrial and commercial segment.
The firm's competitive differentiation rests on specialized domain expertise in radiological and nuclear regulatory work, deep direct relationships with DOE and NNSA program offices, and the capital and scale backing of its ASRC Industrial parent. RSI recently expanded its technical consulting capabilities into nuclear security, safety, construction, and operations through the acquisition of Sigma Science, Inc.
RSI operates on a project-based professional services revenue model, delivering through direct enterprise sales teams that engage federal procurement offices and industrial facility operators. Pricing is not publicly disclosed and is custom to each engagement. Marketing and demand generation are primarily digital, centered on the rsienv.com website, with a formalized 'Partner With Us' intake channel for subcontractor and teaming relationships.
