1 Getting at the last 25% SWANA Evergreen Chapter Workshop February 24, 2017 Tracie Bills SCS Engineers

2 AGENDA 1 1. Defining the Last 25% 2. Drivers for Diversion 3. Municipality Next Steps City of San Jose City of Oakland City of San Francisco 4. Hauling Company Direction Green Waste Waste Management

3 Defining the Last 25% Why the Last 25%? How do we measure diversion? Material Sent to Landfill MSW Directly to Landfill MRF Residuals AD /Composting Residuals Drivers for California AB 341 Mandatory Recycling AB 1826 Mandatory Organics Focus on Organics out of Landfill to Reduce GHG

4 1989 AB 939 Diversion and Planning Mandates 2000 Statewide Diversion Rate of 42 % 2011 AB % Recycling Goal by Statewide Diversion Rate of 27 % 2006 AB 32 GHG Emissions Cap by

5 The Focus for Today and Aspiration for Tomorrow Easily Diverted Recyclable Materials 30-40% Low cost, high diversion potential Common materials - OCC, paper, metals, basic plastics, glass Local infrastructure available Success through best practices Today Harder to Divert Organics 20-30% Food waste, green waste Infrastructure limited Higher level of segregation and best practices required Emerging Challenging to Divert 10% Small rigids, flexible packaging, etc. Not compatible w/ existing infrastructure Contamination potential Investment needed to prove solutions Manageable? - 20% Not separable Sanitary wastes, dirty streams, Trash High cost to separate/clean If not landfill, need alt infrastructure Diversion Focused Management Sustainable Materials Management Materials Management Two different approaches Informed by science Focused solely on environment Tomorrow Unknown

6 Organics Out of Landfill 3 rd largest source of methane production Methane Short lived GHG that s 72 times more potent then 1 ton of carbon over 20 years 6

7 What are Municipalities doing to manage the last 25%

8 City of San Jose 3 Focus: All Material Touched to Increase Diversion New hauling contracts 2012 Collection MRF Processing AD Facility Services Source Separation Wet/Dry Mixed MRF Organics Processing

9 San Jose Mixed MRF MSW sent to MRF Organics Fraction sent to AD Residual Fraction sent to Landfill

10 San Jose Anaerobic Digestion Source Separated at Business Organics Fraction of MSW Process Screened for Glass Composted Screened for Trash Residuals sent to Landfill

11 San Jose Food Waste Pilot SAFE Food Waste Hierarchy Hub & Spoke Creativity & Participation

12 San Jose Getting at that Last 25% Source Separation Wet/Dry Mixed MRF AD / Composting SAFE Relying on Outreach, Education and Technology Putting money into programs and technology 2025 Zero Waste Goal / Strategic Plan Next Steps Having 100% of MSW going to Mixed MRF Collaboration with Hauler on Outreach Collaboration with Processors on Technology Advancement Open to New Ideas

13 City of Oakland Focus: 1. Source Separation 2. Source Separation 3. Source Separation Last 25 years - Tubs to Carts Invest in Source Separation Proven Strategy

14 Oakland New Collection Contract 2015 Included Fully Funded Infrastructure MRF Processing Organics Material Recovery Facility Services Source Separation Wet/Dry Mixed MRF Organics Processing

15 Oakland Mixed MRF Current: Commercial Dry Waste New: Com/MFD/Resi MSW sent to MRF Organics Fraction sent to Post Processing (Organics Material Recovery Facility)

16 Oakland Organics Material Recovery Facility Residuals from Mixed MRF Secondary Sort Organics Fraction of MSW moves on to Organics Process Residuals

17 Oakland No Organics to Landfill Source Separation Alone Won t Get You There Cannot Make Everything into OMRI Certified Compost Looking at Alternates Harm Reduction Multi-Faceted Program Keeping Material out of Landfill Look at Material that Harm the Environment (i.e. Pharmaceuticals) California Product Stewardship Council Alameda County Pharmaceutical Plan

18 Oakland Getting at that Last 25% Source Separation Wet/Dry Mixed MRF Secondary MRF Sort Organics Processing Relying on Outreach, Education and Technology Priority Keeping Organics out of Landfill Next Steps Complete OMRF Focus on Outreach and Education to all Sectors

19 San Francisco Focus: To Reach their Climate Goals Zero Waste to Landfill 50% of Trips Taken by Sustainable Modes 100% Renewable Energy Protect and Grow the Carbon Sink Service Source Separation MRF Processing Composting New Plan for Mixed MRF and AD

20 San Francisco Pier 96 MRF $11.6 Million Upgrade Targeting Asceptics, Gable Tops, Textile, Film Plastic, PLA Major investment Sending Residuals to LA Won t Announce Program Until July 2017 NEW MRF Facility Plans Mixed MRF Anaerobic Digestion Composting Source Separation and Clean Compost

21 San Francisco Mandatory Recycling and Organics (2009) Commercial / MFD Enforcement 50% Surcharge if Recycle/Organics in Trash It Works! New Residential Program 16 Gallon Carts Roll Out Neighborhood by Neighborhood Bin Audits Rethink Disposable

22 San Francisco Getting at that Last 25% Source Separation Mixed MRF AD / Composting Relying on Outreach, Education and Technology Focusing Upstream on Purchasing Using Enforcement and Surcharges Close Collaboration with Hauler Next Steps New Mixed MRF and AD Facility Rate Study Roll Out of 16 Gallon Carts Always looking for New Technologies

23 What are Haulers doing to help with the last 25%

24 Greenwaste Recovery Focus: 1. Make Clients Happy 2. Divert as much as Possible How? Develop Companies that have Innovative Systems Zanker Green Waste Recovery Z-Best ZWED Residual Management

25 Zanker C&D Recycling Always Residuals Material may be so small not worth capturing Recycling material isn t always an option Shred Painted Lumber: Bio Mass or Mulch Furniture: break up to take good wood or metal Wood Removal: water bath system, air system, optical sorting Don t Process Everything Opening Bags / Dangerous (unless by equipment)

26 Greenwaste Mixed MRF All MFD and Commercial Waste from San Jose Does Not Own Landfill Innovation with Material Recovery Material: Carpet, Waxed Candles Residuals Sent to Z-Best Paper, Food Scraps, Diapers

27 ZWED Anaerobic Digester Source Separated Food Scraps Organic Residuals Compost On-Site/Send to Z-best

28 Z-Best Compost Facility Source Separated Food Scraps and Yard Trimmings Organic Residuals Post Processed Organics from ZWED Residuals Screen Compost Densimetric Table Sent to Landfill

29 Greenwaste Getting at that Last 25% Technology Innovation to Find Markets for Material Upgraded Facilities Sustainability Plan / A Green Company Next Steps: To continue to go above and beyond the competition Think Outside the Box with Management of Materials Look for New Contracts with Other Municipalities

30 Waste Management Focus: 1. Efforts to Reduce GHG Emissions 2. Technology 3. What is the Cost for the last 25%? Utilize Innovative Technologies and Focus on Material that Makes the Biggest Impact

31 Waste Management 88% Increase in amount of recyclables managed since M Tons of recyclables extracted from the waste stream 104 Materials recovery facilities owned/operated by Waste Management WM has invested over $1 billion in recycling infrastructure

32 Waste Management What is Waste Management Doing for Communities? Oakland and Los Angeles: Diversion King County / Seattle Portland Recycling the Things that Make an Impact Doing What their Customers Want Technologies are a Big Piece Waste To Energy MRF s (Mixed, Single-Stream) Anaerobic Digesters (Wet/Dry) Others? Capturing Landfill Gas

33 Different Technologies Eismann NOWON ZWE SmartFerm SAFE Yield Biogas Solutions

34 Waste Management Diversion Should not be the Focus Picking what is left and deciding if it is worth removing

35 What is the Goal? To Recycle More? To Reduce GHG Emissions? 1 California Diversion Driven and Focus on Keeping Organics Out of the Landfill Oregon/Seattle Focus on Materials with High GHG values Do we Change Directions? Or Will We Get to the Same Place?
