What Chemical Waste Management of the Northwest, Inc. does

Chemical Waste Management of the Northwest, Inc. (CWM) is a wholly-owned subsidiary of Waste Management (NYSE: WM) and operates an RCRA Subtitle C hazardous waste landfill in Arlington, Oregon, under EPA Part B Permit # ORD 089 452 353 and Oregon Department of Environmental Quality oversight. Founded in 1976, CWM provides treatment and safe disposal for industrial and hazardous waste streams, including stabilization, solidification, micro/macroencapsulation, spent potliner treatment, reactive metals treatment, solar evaporation, and PCB management under TSCA regulations. The facility is rail-served, employs approximately 55 people, and sits within an 11,000+ acre buffer zone on a 22-acre permitted footprint.

CWM operates as part of Waste Management's broader Pacific Northwest integrated environmental services platform, which encompasses seven active landfills, four recycling centers, and five transfer stations across Washington, Oregon, Idaho, Alaska, and British Columbia. The platform deploys proprietary AI-powered optical sorting systems and eddy current separators at facilities including the $47M Portland Recycling Facility (38 tons/hour, 10 AI sorters, 94 conveyor belts), the Cascade Recycling Center in Woodinville (650 tons/day serving 250,000 households), the JMK Fibers facility at the Port of Tacoma (24 shipping docks, rail-served), and the Spokane SMaRT Center (37% capacity expansion underway). Adjacent landfill assets such as Columbia Ridge include 12.8 MW of landfill-gas-to-energy generation and 92 wind turbines producing 150+ MW.

Revenue is generated through transaction-based tipping fees at landfills and transfer stations (varying by waste type, weight, and jurisdiction), subscription-based residential curbside collection, and enterprise-level hazardous-waste contracts. Customer segments span residential households, commercial and industrial businesses, multifamily properties, municipal governments, healthcare providers, and industrial hazardous-waste generators. The entity functions as a regional operating subsidiary within WM, with no public financial disclosure and limited standalone decision rights beyond facility-level operations.
