Green Rock Strategies, LLC

What Green Rock Strategies, LLC does

Green Rock Strategies, LLC is a privately held waste management and environmental services firm founded in 2016 and headquartered in Charleston, South Carolina. The company operates across seven service lines covering commercial and industrial waste management, recycling, logistics, and sustainability consulting, and documents cumulative operational scale of more than 251 million gallons of wastewater managed, 1.8 million tons of materials handled, 1.2 million tons recycled, and 253,000 truck loads coordinated. It serves enterprise customers across infrastructure, rail transportation, environmental remediation, real estate, and industrial services, with publicly named clients including AECOM, Norfolk Southern, Ceres Environmental, Clean Harbors, Greystar, and Action Environmental.

The firm was founded by Trey Smith, a 20-plus-year waste industry veteran and former Director of Special Waste at Republic Services. Green Rock positions itself as a coordination and oversight layer built on exclusive affiliate relationships across multiple service lines rather than as a vertically integrated asset owner. The company is structured as an LLC with 11-50 employees, holds supplier prequalifications with ISNetworld and Avetta, and operates multi-region coverage including a Southeast base (Charleston, Atlanta) and a West Region. No funding rounds, patents, trademarks, or AI/ML capabilities are disclosed.

The business model is project- and contract-based: Green Rock sources, coordinates, and oversees waste, recycling, and logistics services delivered through affiliates on behalf of enterprise and industrial clients. Revenue mechanics are not disclosed, but the named-customer profile, supplier certifications, and multi-region coverage are consistent with a professional services and brokering model rather than fee-for-service hauling.
