Landfill Reclamation + Industrial Redevelopment = Residential Lands, St. Catharines, ON
Finalist in Category 2 - Sustainable Remediation Technologies & Technological Innovation
This project demonstrates leadership in environmental remediation :
- 5,000 T of petroleum contaminated soils bio-remediated on-site, zero off-site disposal
- Building demolition - all metal and wood waste sent to a recycler for subsequent re-use. All concrete walls, floors and footings recycled on-site and recycled concrete (~10,000T) was re-used as aggregate for sewer bedding and roadways on-site where geotechnically appropriate, precluding purchasing virgin aggregate (saving 10,000T of a resource) and precluding approximately 500 trucks driving through the adjacent neighbourhood to deliver it.
- The first large scale (3.5 acres) removal of a landfill and conversion to residential lands in Ontario and possibly Canada, with >99% recycling of the landfill degraded waste materials and cover. The adjacent municipal golf course, situated on a landfill, received over 92,000 m3 of waste materials, cover and top soil from this site to enhance grades, raise tee blocks and greens, create a water feature and berms between fairways, and this was all paid for by the developers. Off-site disposal of above-criteria waste was limited. All metal and tires found in the waste were recycled off-site.
With the innovative use of soils and landfill materials, the project became cost-efficient enough to go forward; hauling these materials to a landfill would have been totally cost-prohibitive. Removal of the 3½ acres of landfill allowed the Municipality to gain 3½ acres of new residential tax lands, fit perfectly with the Regional Municipality’s ‘Smart Growth’ initiatives and fit the Province’s ‘Places to Grow’ initiative.
