3 About Shanks Shanks Group plc is a FTSE-listed waste-to-product specialist, focused on the treatment of municipal, commercial and hazardous waste in Europe and North America

4 Orgaworld 100% Shanks Group Subsididiary Founded in 2001 Existing sites in Canada, the Netherlands and the UK Specialized in organic waste processing anaerobic digestion composting waste water treatment Innovation: waste to chemicals/waste to protein treatment of over mt organic waste/year

5 Orgaworld Canada Ltd. Dry AD + Composting Surrey tunnel composting, Ottawa tunnel composting, London

6 City of Surrey Rethink Waste The Vision To fuel Surrey s waste collection trucks with renewable natural gas generated from Surrey s curbside organic waste

7 City of Surrey Rethink Waste The Objectives 1. Achieve 70% diversion targeting residential organic waste using CNG collection trucks. (Achieved) 2. Establish an Organic Waste Biofuel Facility to process residential organic waste and produce renewable natural gas fuel. (In Construction) 3. Ensure Goals 1 & 2 are delivered in an economically and environmentally sustainable way. (Achieved)

8 City of Surrey Closed Loop

9 City of Surrey Funding Approach P3 approach preferred project delivery model DBFOM, 25 year term Private Partner carries most risk: technical and commercial; private financing; commercial waste; guaranteed annual volume of RNG; processing & marketing of compost City s risk limited to providing land, guaranteed residential organic waste: feedstock, paying tipping fee, and RNG ownership Estimated Cost: $67.6 M (NPV) P3 Canada approval at $16.9 M (25%): Sep RNG arrangement between the City of Surrey and Fortis BC (provincial gas utility):city to repurchase 100% of the useful gas generated at the facility

10 Surrey Biofuel Facility - 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. Production of class A compost 6. Maximum recycling of residual products 7. Maximum energy efficiency 8. Nuissance Minimization: best odour abatement

11 Surrey Biofuel Facility - Design Choices Why Dry Anaerobic Digestion? L&Y waste determines choice for dry AD!

12 Surrey Biofuel Facility - Design Choices Why Dry Anaerobic Digestion? 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 No extensive pretreatment necessary Minimal weir & tear on mechanical equipment: low maintenance and high reliability (low down time risk)

13 Surrey Biofuel Facility Tunnel Design

14 Surrey Biofuel Facility - Design Choices Why Dry Anaerobic Digestion? Batch process resulting in high reliability Suitable for solid organic waste and easily integrates liquid organic waste Operates in the mesophilic and thermophilic range Modular system, easy to expand Digestate processing relatively easy Very robust System

15 Surrey Biofuel Facility - Design 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 Lowest possible footprint due to spigot aeration system Internal recycling of air for maximum process control Automated water spraying for moisture control

16 Surrey Biofuel Facility - Design Choices Why Tunnel Composting? Perfect Process Control

17 Surrey Biofuel Facility - Design Choices Why Water Wash + Vacuum Pressure Swing Absorption? Desired RNG quality Sufficient CO2 recovery of high quality for internal use; reactor inertization Innovative solution of proven technologies Local supplier brings local expertise

18 Surrey Biofuel Facility - Design Choices How to refine the compost? Two rotating drum separators Ballistic separator Metal recovery system Maximum Waste Diversion!

19 Surrey Biofuel Facility - Design Choices What Odour Abatement? Stage process consisting of: Ammonia removal Air cooling Biofiltration Exhaust via 70 m stack Odour control by E-nose technology and H2S sensors
