Maple Leaf Foods Inc. & Enviro-Stewards

In 2015 Maple Leaf Foods launched a formal environmental sustainability program targeting reductions in energy and water use across their manufacturing network. The Elmira, ON based engineering firm, Enviro-Stewards Inc., was contracted to find energy, water and wastewater savings opportunities to reduce utility expenditures and environmental footprints at Maple Leaf’s 12 largest facilities.  Based on the success of the first dozen assessments, Enviro-Stewards was retained to complete energy, water and wastewater savings opportunity assessments at another 22 Maple Leaf facilities across Canada during 2016 and 1 additional facility in 2017.

As part of this collaboration, Enviro-Stewards and Maple Leaf Foods sponsored the construction of a biosand filter (BSF) for each of the 35 Maple Leaf food facilities that were audited by Enviro-Stewards during 2015, 2016, and 2017. Here is the social impact of the project:

Safe Water Points

People With Safe Water

GHG Emissions Avoided

Volume of Water Provided









St. Paul's Nursery: 175 students and 6 staff benefit from a biosand filter donated on behalf of Enviro-Stewards and Maple Leaf Foods. 

Yei River County Prison: The first biofilter will provide safe water to the female inmates.

Community Health Agent Workshop:  Nearly 45 students attended the workshop in Koboko, Northern Uganda in February 2017. Participants learned about the health and economic benefits of BSF technology and how to market it to the community.

BSF Training: MLF sponsored two BSF's for Namugongo Orphanage, near Kampala, Uganda. Pictured above, a member from Connect Africa trains two orphanage leaders how to maintain the BSF filters.
