4. Quick Facts
โข 36,800,000 people in Canada in 2017
โข 10 million square kilometers
โข Generated 34.1 million tonnes of waste in 2014 or 961 kg/capita
โข Diverted 9 million tonnes or 255 kg/capita
โข Disposed 25.1 million tonnes or 707 kg/cap
โข National Diversion rate of 26%
โข Diversion can be as high as 40 to 60% in residential sector

18. Surrey Environmental Benefits
โข 115,000 t diverted from landfill
โข Eventual full elimination of CO2e from CNG waste
collection fleet based on RNG use
โข 25% reduction in Surreyโs corporate CO2e through
RNG use

25. Costs
Technology Capital costs Operating Costs
In-vessel $500 to $1000
per design tonne
$80 to $100 tonne
AD $600 to $1000
per design tonne
$70 to $110 tonne
AD Costs do not account for external use of biogas or carbon credit revenues

26. Lessons Learned
โข Siting facilities can be difficult
โข Odour is the number one issue donโt underestimate it
โข Need a market for your end product
โข Understand your feedstock โ what you want to collect and how
โข Look at your entire waste system from a costing perspective
โข Donโt overestimate revenue

27. Single vs. Multi-Family
โข Single detached homes are on the
decline in Toronto and parts GTA.
โข This trend is common to many
jurisdictions across Canada and the
US
โข Gap in diversion rates between
Single Family Homes and Multi-
Family Homes
โข More recyclable/organic material
moving to a harder to capture
housing market

28. Multi-Family โ Potential Case for MWP
โข The challenge:
โ Increased urban growth
โ Intensification
โ Achieving 60 to 75% diversion
rates
โ Landfill bans
โ Circular Economy
โ Carbon reduction

29. Conclusion
โข Significant Facility Development has occurred in
Canada
โข Still have lots of organics in the waste stream
โข Circular Economy, Carbon, higher diversion
rates are driving continued growth in organics
โข AD is becoming a dominant new technology
โข Mixed waste processing is being studied
