Opened in July 2017, the City of Calgary Composting Facility is the largest in Canada to use in-vessel composting technology. Yearly, the facility can process over 100,000 tonnes of food and yard waste brought in through the City of Calgary Green Cart collection program, along with 45,000 wet tonnes of de-watered biosolids from municipal wastewater treatment. After one year of operation, the facility processed over 100 million kilograms of organic material.
Landfill space in Ontario is limited – no new landfills have opened in the past 20 years. This gives municipalities a powerful incentive to reduce the amount of waste they generate.
