Maple Reinders was contracted on a Design/Build basis to undertake the replacement of a defunct organic waste processing facility for the city of Guelph, able to process 30,000 tonnes a year of source separated organics (SSO).
The design of the new facility calls for the re-use of existing foundations and remaining sound structural components. The in-tunnel aerated static pile process utilized a patented process technology, with four Phase 1 composting tunnels and three Phase 2 tunnels.
Due to public concerns about odour, Maple Reinders proposed a stringent odour control system which included air curtains installed around rapid-roll up truck bay doors in the tipping area to prevent fugitive emissions. The city’s requirement of 1 Odour Unit (OU) at the site perimeter led the team to incorporate a Biorem® biofilter with an exhaust stack to provide maximum odour control.
