Summary of PilotSummary of Pilot• Confirmation of sampling strategyConfirmation of sampling strategy• Identified that the majority of land-filled Identified that the majority of land-filled
waste in Regina could be diverted waste in Regina could be diverted through recycling and composting through recycling and composting activitiesactivities
• More data analysis was required to More data analysis was required to identify the actual composition of each identify the actual composition of each category relevant to diversion activitiescategory relevant to diversion activities
• Slight alterations needed to be made to Slight alterations needed to be made to existing categoriesexisting categories• Addition of a household hazardous categoryAddition of a household hazardous category
