Miller Waste Systems Inc. is a Canadian environmental services company focused on the collection, haulage, recycling, and repurposing of organic and inorganic waste and recyclables. It serves municipalities and industrial, commercial, and institutional customers, supporting everyday waste management as well as construction and demolition projects. The firm operates transfer stations and Material Recovery Facilities where it sorts and processes plastics, paper, cardboard, steel, aluminum, and glass, and oversees the sale and transport of recycled material to the commodity marketplace.
