1 Diverting Food Waste From Landfills Using Anaerobic Digestion

2 STATISTICS Food Production Use of Resources 10% 50% 80% of the total U.S. energy budget 1 of the U.S. land 1 of all freshwater consumed in the U.S.1 1. NRDC Issue Paper Wasted: How America is Losing Up to 40% of Its Food from Farm to Fork to Landfill. 2

3 STATISTICS Wasted Food % 1We of food in the U.S. goes uneaten 1 million tons of organics end up in landfills or incinerators 2 are throwing away $165 Billion 1.

4 FOOD WASTE Percentage of Total North American Food Loss 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Wasted Consumed Milk Meat Grain Seafood Products Food Category Fruits & Vegetables 1.

Numbers represent the total loss across the supply chain and are calculated collectively for USA, Canada, Australia and New Zealand. 4

6 quasar energy group INDUSTRIAL Anaerobic Digesters AGRICULTURAL MUNICIPAL

7 PRODUCTS Renewable energy natural gas, vehicle fuel (CNG/LNG), electricity & heating/cooling. Animal bedding, peat alternative and compost equate liquid plant food is a natural solution in lieu of chemical fertilizers. CNG Electricity Heat/Cooling Reduced greenhouse gas emissions, cleaner air, soil and water equate liquid plant food 7

8 CO-DIGESTION Challenges & Considerations Contamination: Wax-coated cardboard Anything not organic in nature: plastic, metal, glass, sand, etc. - essentially anything not included in original sample Addition operating costs necessary for accumulation of inorganic material in the ADS Result: damaged receiving equipment, unscheduled maintenance on tanks and pumps Limitations: Digester cannot accept petroleum based products, biomass sources with metal, plastic, paper, or glass contamination, or sources with heavy metals Plastic, straw, wood and cardboard 8

9 CASE STUDY Depackaging Design: Auger Feed with Hopper Hammermill Shredding System Screw Press Extrusion Drum Washer Finishing Depackaging equipment in quasar s Zanesville, Ohio, facility Depackaging equipment wax-coated cardboard aluminum cans plastic bottles and containers others including mylar bags and paper/paper board 9

10 CASE STUDY Depackaging Liquid Waste Streams: Milk, sour cream, yogurt, and dips, drinks and concentrates including fruit juice, ice tea, coffee syrups, and frozen concentrates, and condiments. Customers: Dairy manufacturing, distributors, coldstorage warehouse, and brokers. Capacity: 1-2 truckloads per day (20 tons each). Organics Content: % of product weight is organics % organics capture rate. 10

11 MACERATION Pumpable Organics quasar s first Fall Season managing organics from regional grocery stores highlighted the need to develop macerating technology at the generator s site that would facilitate delivering pumpable (slurry) organics to our plants. 11

12 SOLUTIONS Digester Ready Waste Streams q uasar has developed technology, the Grind2Energy system, with InSinkErator that will allow us to accept and process contaminatefree AD-ready waste streams from: food manufacturers hotels cafeterias supermarkets restaurants colleges & universities hospitals sports venues The Grind2Energy system is a high volume, low water consumption option that is simple to operate. On-site separation with grinding reduces or eliminates organic loss from contamination, storage and odor concerns, and simplifies implementation of organics capture program 12

13 SOLUTIONS Food Waste Management The AD facility captures and converts the methane into a renewable resources such as: A liquid waste hauler transports the slurry to a nearby AD facility Grind2Energy grinds food waste quickly and efficiently Compressed Natural Gas Electricity Heat The food waste slurry is transferred to a holding tank 13 13

14 SOLUTIONS Food Waste Management The Power & Potential of Food Waste Partnerships 14 14

15 SOLUTIONS Simple Implementation Specifications: Manufactured in USA 10 Horsepower Grinding Unit InSinkErator s most powerful grinder Can process 700 pounds of food waste per hour Unique grinding and moisture control resulting in pumpable biomass 15 Copyright quasar energy group

16 SOLUTION Improved Storage Storage tanks (right) are leak free and odor free, eliminating odors and pests. Tanks are equipped with automated level detection and easy load out ports. Below traditional storage bins leak, smell and attract rodents and are easily vandalized Copyright quasar energy group

17 TRANSPORTATION Impact of Pumpable Material Higher Risk of Contamination Low Risk of Contamination Weekly Pick-Ups of Partial Loads Level Sensor, Pick-Up When Full Less Maneuverable Easily Maneuvered Heavy Truck may damage pavement Lighter Truck less pavement damage Copyright quasar energy group

18 CASE STUDY Cleveland Brown s Stadium FirstEnergy Stadium Grind2Energy quasar energy group FirstEnergy Stadium processed more than 72,000 pounds of food waste during the 2013 Cleveland Browns season using Grind2Energy and quasar energy group. 18

19 CASE STUDY The Blackwell Inn at OSU The Blackwell Inn and Conference Center at The Ohio State University Food material is ground by an InSinkErator unit. Diverts 80 to 85% of total waste from the landfill for about the same cost as disposing of all materials as trash. Eliminated need to use bag liners in kitchen waste bins Diverts approximately 20 tons a month from the landfill. Materials are taken to an anaerobic digester operated by quasar energy group.

20 CASE STUDY Tower City Center Forest City is the first Cleveland company to install an InSinkErator Grind2Energy system at Tower City Center. The system services the many decentralized restaurants and food court vendors

21 VALUE PROPOSITION Environmental Impact Reduce carbon equivalent emissions1: Sending 20 million tons of organic substrate (6% of annual U.S. landfill dumping) to digesters can remove the carbon-equivalent emissions of over 3.2 million automobiles. Reduced methane emissions1: 38% of landfill methane is emitted directly into the air, making the diversion of organic substrates from landfills to digesters the largest single environmental benefit of digester use. 1.
