3 Introduction The Region of Peel provides waste collection services to 330,000 single family households and to 94,000 apartment/condo/townhouse units in the cities of Brampton and Mississauga and the Town of Caledon In 2014, Peel managed 520,000 tonnes of residential waste and achieved a 46 percent diversion rate Peel s goal is to divert 90 percent of waste from disposal by

4 Expectations Regarding Bi-weekly Garbage and Recycling Collection Greater efforts to reduce waste to landfill will be achieved with curbside bi-weekly garbage and recycling collection Peel anticipates an increase of 15,000 tonnes in curbside collection of source separated organics (SSO) due to the change from weekly to bi-weekly garbage and recycling collection and the continuation of weekly SSO collection

5 Background: Collection Current Waste Collection: Weekly: garbage (two bag standard), recycling, SSO, yard waste (seasonal), bulky items 2016 Waste Collection: Weekly: SSO, yard waste (seasonal), bulky items Bi-weekly (alternating): garbage and recycling SSO Collection: Pilot areas: Peel-wide: began in

20 Bi-weekly Garbage and Recycling Pilots SSO Participation Residents already participating in SSO collection participated more during the pilots 30 percent of garbage stream was comprised of SSO Plastic liner bags were not an issue, most residents used certified compostable plastic liner bags Spring 2015 audit of Peel households (non-pilot areas): 45 percent SSO and 7 percent yard waste in garbage stream

31 Expected Results of Bi-weekly Garbage and Recycling Collection SSO collection expected tonnage increase of 15,000 tonnes Estimated from observations of bi-weekly pilot areas of 6,000 households 30 percent organics still remain for capture in the garbage stream Operations Stretched and need to find partners for processing additional tonnages Contamination Increased diversion of all material streams from the landfill

32 SSO Contamination Rates in Bi-weekly Garbage and Recycling Pilot Areas Caledon Rural/Urban SSO Collection Brampton Cart SSO Collection August 2012 November % 0.22% 14.86%* 0.62% *Influenced by one garbage bag in the collected sample 32

33 Region of Peel Residual Waste Successes Waste Costs Reductions Less waste to landfill Bi-weekly pilots Compost Operations Bi-weekly garbage and recycling Screening plant New processes

34 Conclusions 97 percent of SSO collected in Peel is being diverted from landfill to date based on operational adjustments January 2016: Peel will be collecting garbage and recycling bi-weekly, SSO and yard waste (seasonal) weekly Tonnage and participation increases are based on audits in pilot areas Contamination rate increase in SSO initially expected based on audits in pilot areas
