The Journey Three epiphanies Two memes One theme Policy implications 3
Three Epiphanies Food scraps - liquid, not solid WRRFs not POTWs or WWTPs Renewable feedstocks unique challenges 4
Two Memes Banana Peel: My real-world choices what should I do with my banana peel, or melon rinds? Food fights: growing competition over reliable access to high-quality feedstocks 5
Theme: Adjacent Possible Good ideas are built out of a collection of existing parts Ideas want to reinvent themselves by crossing conceptual borders Best served by connecting than protecting ideas Build inter-agency collaboration 6
Epiphany #1 Solid, or Liquid? Answer: 70% water 1992: NYC s first major SWMP included aggressive organics goal; DSNY asked DEP for help legal, mandates, incentives 1995: City Council demanded pilot; three apartment complexes; 200 units 1997: DEP report de minimis impacts; legalized household in-sink food waste disposers citywide 7
Epiphany #2 - Rebranding NACWA (National Association of Clean Water Agencies) WEF (Water Environment Federation) Water Resource Recovery Facilities (WRRFs) Utilities-of-the-Future GOAL: Energy-Neutral/Positive Operations 8
Epiphany #3 Feedstocks Wind, Solar, Geothermal, Wave? Unlimited; no cost; residual-free; idiot-proof Biogas? Consistent, reliable sources Contamination/specifications Collection/delivery logistics EPR/Product Stewardship? Residuals management Markets engagement energy (on/off-site) Credit for MSW solution 9
What should I do with my banana peel?* *If I m concerned about global warming. Should I: Asked by Kendall from Brooklyn NPR All Things Considered June 2007 NBC s Today Show November 2007 Try to compost it in my backyard or worm bin? Put it in a garbage bag for collection in a truck headed to a landfill or waste-toenergy facility, or compost facility? Pulverize it in my food waste disposer and send it thru the sewer to a wastewater treatment plant for processing into clean water, fertilizer products and renewable energy?
Meme #2: Food Fights Food waste reduction Food waste recovery Competition over access 11

Beyond Waste: A Sustainable Materials Management Strategy 8.4.1 (e) In Sink Food Scrap Disposers Many communities manage some food scraps in combination with biosolids by allowing or encouraging the use of kitchen sink food disposers or garbage disposals in both commercial and residential settings essentially, sending it to the local treatment facility along with other wastewater. Encouraging or requiring these garbage disposals in certain circumstances can further recycling goals. 14
Co-digestion in NY 15
Food Scrap-Dedicated AD Long Island Composting 6 MW Genesee Biogas 3 MV Commence Construction in 2017 16
FWD Demonstration Projects Goal: Assess efficacy of in-sink disposers Research gap: effective use Philly, Chicago, Milwaukee, Tacoma, Boston, Calgary @ 500 disposers homes/apts. Waste audits/behavioral surveys 17
Philadelphia CleanKitchen/GreenCommunity Project Two neighborhoods/175 homes received first disposer Adopted Building Code Disposers required in residential construction (as of January 1, 2016)
Top-Line Results 100% use/participation 30-60% reduction in food scraps (20% still packaged) value - $100 +/- 19

Elsewhere in the Region. Green Energy Facility New 24,000 SF facility will convert food that is no longer edible into clean energy. This keeps waste out of the waste stream and produces 1.137 megawatts of electricity, providing up to 40% of the energy needed to run our 1.1 million square-foot distribution center in Freetown, MA 22
