The Compo-Haut-Richelieu Regional Food & Green Waste Composting Center (COMPO) is distinguished by the relatively simple compost feedstock preparation process.  The facility, located just south east of Montreal in Saint-Jean-sur-Richelieu (QC), uses eight concrete bays.  Each bay is 10 feet by 312 feet and is served by two 100 horsepower BDP agitators and designed to porcess 50,000 TPY.  The facility uses organic material, including green waste and food waste, collected from the surrounding municipalities brown bin program (BRUN'O Lebac).  COMPO is a joint venture between MRC du Haut-Richelieu and its 14 municipalities and their private partner, GFL Environmental.

Those familiar with the facility have praised the fully enclosed facility.  Mayor Suzanne Boulais, of Mont-Saint-Gregoire (one of the 14 municipalities) has stated his belief that the opening of this facility coupled with citizens' efforts in recycling and recovery programs, which has significantly reduced landfill waste, will further spur momentum to end the landfilling of organic materials in Quebec and to increase the reduction of greenhouse gasses in the area.
