CWST Company Overview

Casella Waste Systems, Inc. is a regional solid waste, recycling, and resource management company that operates primarily in the northeastern United States. The company provides collection, transfer, disposal, recycling, and organics services for residential, commercial, municipal, and industrial customers. Casella operates in the broader environmental services and waste management industry, with revenue primarily generated through integrated waste collection routes, landfill operations, recycling processing, and resource solutions services. The company also provides services related to wastewater treatment, soil remediation, and construction and demolition material management.

Casella was founded in 1975 by brothers Douglas and John Casella in Vermont as a local waste hauling business and expanded through acquisitions and vertical integration into disposal and recycling infrastructure. Over time, the company developed a regional network of landfills, transfer stations, material recovery facilities, and collection operations that support its integrated operating model. Its strategic positioning is tied to strong regional density in the Northeast, ownership of disposal assets, and increasing exposure to recycling and sustainability-focused services.
