Maple Reinders was selected to undertake the replacement of a defunct composting facility for the City of Guelph located at the Waste Resource Innovation Centre. The design of the new facility called for the re-use of existing foundations and remaining sound structural components. The in-tunnel aerated static pile process utilized a patented process technology from Christiaens Group, one of Maple Reinders’ partners on the project, 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.
The facility also includes an indoor maturation area and administrative offices. The facility is operated by Maple Reinders’ subsidiary AIM Environmental Group.

Organics Waste Management
This facility marks the fourth Canadian environmental project which we will deliver under the Public Private Partnership format, a first amongst its fellow Canadian contractors.
Constructed the High Solids Anaerobic Digestion Facility, which was integrated into the operation of the existing Integrated Processing and Transfer Facility and the Edmonton Composting Facility.
Once compost is placed in the tunnels, they are sealed and oxygen is added through an aerated floor grid to promote biological activity.
