13 2.1 3D - respresentation

14 2.2.1 Design Objectives 1. Safe, robust and flexible design 2. Process a total of 80,000 tpy of City Waste 3. Maximize biogas production from City Organic waste and solid/liquid ICI wastes in a flexible process 4. Biomethane of Fortis BC methane quality (>96% CH4) 5. Maximum recycling of residual products 6. Production of class A compost 7. Maximum energy efficiency 8. Best possible odour abatement process

15 2.3 Process Choices 2.3.1: Why Dry AD? L&Y waste determines choice for dry AD!

16 2.3 Process Choices Why Dry AD? Criteria Dy AD Wet AD Orgaworld examples BIOCEL Lelystad Greenmills Footprint +/- + Gasyield +/- + Energy efficiency +/- +/- Reliability + +/- Flexibility + +/- Maintenance + +/- Pre-treatment + - Wastewater Best suited for complex organic waste, incl. L&Y waste 2. No risk of downtime due to failure of pretreatment line 3. Minimal weir & tear on mechanical equipment: low maintenance and high reliability

17 2.3 Process Choices Why Tunnel Composting? Perfect Process Control

18 2.3 Process Choices Why Tunnel Composting? Criteria In-vessel composting Aerated pile Orgaworld examples London, Ottawa Drachten Working conditions + +/- Reliability + + Footprint + +/- Odour control + +/- Process control No exposure of staff members to contaminated air 2. Lowest possible footprint due to spigot aeration system 3. Internal recycling of air for maximum process control 4. Automated water spraying for moisture control

19 2.3 Process Choices Biogas Upgrade Amine washing with heater based natural gas was selected as best, and most reliable technology Residual heat from the amine washing process is used to heat the AD process

20 2.3 Process Choices Why Amine Washing? 1. Highest RNG quality 2. Highest reliability 3. Reuse heat for the AD process

21 2.3 Process Choices Post Treatment Compost screening process consisting off: 1. Two rotating drum separators 2. Ballistic separator 3. Metal recovery system Maximum Waste Diversion!

22 2.3 Process Choices Odour Abatement 1. Staged process consisting off: 2. Air cooling 3. Ammonia removal 4. Biofiltration 5. Exhaust via 70 m stack 6. Odour control by E-nose technology and H2S sensors Best possible odour abatement system!

23 3. Surrey Urban Resources

24 3. Surrey Urban Resources Compost Class A Compost (B.C. Regulation) Agricultural use is traditional compost market Small agricultural market in BC/600 diary farms in the Fraser Valley/Nutrient Surplus Market development City Applications top soil, parks, berms, three starter, etc.. Surrey Residents gardening Wineries Top Soil Production Compost Product Innovation by use Biostimulants Perfect Biological Fertilizer!

25 3. Surrey Urban Resources SRF cement quality 2,000 3,000 tpy* alternative fuel suited for use in cement kilns: pneumatic transportable dry and fine film pieces low ash content/high Caloric Value low Chlorine content (mainly PE) low Sulphate content low heavy metal contents improved air emissions Lower GHG emissions Partner: Lafarge Richmond* Green cement!

26 3. Surrey Urban Resources Biomethane: 3,000,0000 NM3/year Fortis BC methane specification Methane content: > 96 % Heat Value: > MJ/m3 Waste Collection Truck Fuel Ammonia Sulphate: App. 3,500 tonnes/year Fertilizer/Greenhouse Substrate Market Product Status CFIA certificate Metals: 100 tonnes/year Resources with great potential!

27 4. Conclusions Surrey Biofuel Facility Big step forward resulting in: More sustainability Greener City Healthier Environment Happier People Large Innovation e.g. Growth Potential Making Surrey a better place to live.
