Waste Composition studies are periodically conducted by Waste and Recycling Services to help assess the performance of diversion and education programs and inform improvements and new program design. This dataset is for Green Cart waste from residential dwellings, and represents the weighted average of samples of 20-25 residences collected in 22 communities in each of the four seasons of 2020 (88 samples). The communities sampled were selected to collectively represent the range of housing types and demographics in Calgary. The weight per cent composition is provided for a number of material categories and subcategories. For more information please visit: Green cart composting

Annual Waste Volumes provides the number of tonnes of material managed at City of Calgary landfills, through the residential Black (garbage), Blue (recyclables), and Green (food and yard waste) Cart programs, and Household Hazardous Waste program.

Waste & Recycling Performance Measures are used to assess the performance of The City of Calgary's Waste & Recycling service. Five measures have been approved for the 2023-2026 Service Plans and Budgets. See Waste & Recycling plan and budget for more information.
