EPC for Renewable Natural Gas

From conceptual design to commissioning, we do full engineering, procurement, construction (EPC) and O&M for the RNG facilitates. We design, fabricate, and build RNG balance-of-plant systems for landfill, dairy, and wastewater facilities. Our integrated team delivers reliable, code-compliant projects that start up cleanly and operate safely.

Solid Waste Services

Our Solid Waste Services (SWS) team supports landfills across their full life cycle. We cover cell design, permitting, construction, gas collection and control systems (GCCS), leachate collection and removal systems (LCRS), compliance, O&M, cap design, closure, and post-closure care. You can bring us in for one phase or project, or for the whole enterprise of the site.
