Winter Street Sand Recycling Project

Hugh Donovan, P.Eng. - City of Edmonton, Transportation and Streets Department

One of the main challenges facing Canadian cities is the maintenance of their roadway systems to provide safe winter driving conditions. In Edmonton, more than 165,000 tonnes of sand and salt are applied annually to the city's roads. In the past, almost all of these materials were swept up in the spring and disposed of in a landfill. In 2003, the City of Edmonton Transportation and Streets Department and the Edmonton Waste Management Center of Excellence formed a partnership to investigate the feasibility of recycling street sweepings. The winter street sand recycling pilot project, partially funded by a grant from the Federation of Canadian Municipalities Green Fund, had dramatic results. The pilot project was able to recover and recycle 80% of the collected street sweepings for re-use as winter street sand. The Winter Street Sand Recycling Program has proven to be an innovative and unique approach to the handling of contaminated winter street sand. It is believed that this type of recycling initiative has never been undertaken on a production scale. Most municipalities, with their existing infrastructure and activities, should be readily able to duplicate the City of Edmonton's success.
