Things to consider: A key success factor to diverting reusable soils from landfills is being able to match excess soil with receiving sites within development timelines. This beneficial reuse of soil is facilitated through soil matching programs and/or soil banks.

Supporting Ontario Infrastructure Investments and Lands (SOiiL)
SOiiL is a non-profit organization that manages a soil matching registry for Ontario operations. It is modeled on the UK-based CL:AIRE - Register of Materials which provides the same service. The purpose of the SOiiL registry is to “identify excess soil that can be sustainably and beneficially reused appropriately at other sites and development projects.”1 Both soil generators and soil receiving sites register with the program in advance at no cost and then submit soil requirements or information about excess soil to the registry. SOiiL reviews the information and notifies the receiving sites and soil generators if there is a match between the soil offered and required.

Waterloo Soil and Material Management Campus
The Region of Waterloo conducted a feasibility study for a soil banking program where excess soil supplied could be matched with soil demand. This project included the development of an excess soil and sediment database to identify opportunities and timing of excess materials. The Waterloo database is meant to complement the SOiiL database and requires participants to input a soil’s environmental and physical properties.

By-laws reviewed do not generally require the use of a soil registry; however municipalities can help support soil matching by sharing information about SOiiL and other soil banking systems. Municipalities can also create their own soil matching or soil banking programs.
