Evaluating Options and Cost Saving Potential from Food Scrap Collection and Composting City of Glendale Zero Waste Action Plan Zero Waste Associates Rich Flammer Hidden Resources
More than 40 percent of all food produced in America goes uneaten 29 million tons of wasted food waste each year Cost U.S. $100 billion annually American restaurants discard more than 6,000 tons of food everyday U.S. households throw away an average of 600 pounds of food annually 10-15% of what we landfill Using Contemporary Archaeology and Applied Anthropology to Understand Food Loss in the American Food System Timothy W. Jones. PhD
What are we throwing away?

Hierarchy of Options Collection for centralized facility creating fertilizers, soil amendments (composting) or mulches Source reduction (methods to prevent wasted food and other discards) Collection for delivery to farms (feed animals) Collection for delivery to farms (direct land application) Onsite composting or other processing technology Donation to food banks (feed people)
Iowa Health-Des Moines (Iowa Methodist and Blank Children's Hospital) Overall food waste fell 42% from the beginning of waste tracking in Jan 2008 through August ValuWaste Tracker Swedish Medical Center, Seattle Retail soup overproduction was reduced 65% through batch cooking and changes in production procedures. Expired bakery waste was reduced 29% through a change in purchasing procedures. Patient overproduction was reduced 46% by targeting production levels on the non- center of the plate items such as starches, soups and gravies.
About 30 restaurants in Hong Kong are using fines to reduce wasted food $1.30 charged for each leftover sushi at the Ming General restaurant About two customers fined a week All-you-can-eat restaurants in the Philippines, Australia and Canada - also fine wasteful customers A new spin on pay-as-you throw…
Fast Food…Fast Source Reduction Red Lobster switched from paper to cloth napkins and diverted more than 23,000 tons of paper from the landfill annually Wendys stopped printing on their paper napkins and diverted 28 tons a year; Changes in packaging of pickles, mustard and mayonnaise diverted an additional 500 tons annually McDonalds switched from bags to cartons for its hash browns and realized a 74% decrease in paper usage, keeping 1,700 tons of material from becoming waste
Peerless Coffee and Tea One change of coffee packaging machines and reduced the amount of Mylar waste by 95 percent and saves $100,000 annually in reduced packaging supply costs Ghirardelli Chocolate Company One change going from cardboard boxes to durable totes cut annual packaging costs by $520,000, and prevents 350 tons of soiled cardboard waste each year
From fiscal year 2000, approximately 10,614 tons of food recovered Oregon Food Bank estimates 2,122 tons would have been landfilled From 1999 to 2005, nearly $700,000 in grants from Portland Metro Estimated additional food recovery as a result of the grant program was 9,000 tons annually Food Donation as a Resource Management Method
Environmental Benefits of Managing Organics Onsite Low impact management of facilitys own compostableresiduals Improved soil and vegetation become a sink for C02 Decreased pollution of water sources and degradation of soil Savings in fertilizer costs and reduced pesticide use Water conservation
United Kingdom More than one million home compost bins distributed Participation results in almost 200,000 tons/year of diversion Isles of Scilly, UK 78% of its residents using home composters Dr. A.D. Knipe, Environmental Research & Consultancy
Annapolis Royal, Nova Scotia town with Zero Waste Goal Green Cones and Earth Machines for individual backyard composting Neighborhood composters for use on streets and multi-family Earth Tubs for businesses All organics processed at a community level 41% of 60% diverted are organics 85% particpation rate in backyard/neighborhood composting Public drop-off site for yard trimmings
Kauai More than 1,500 bins distributed 2006 survey results showed average of 1,500 pounds of food scraps and yard trimmings diverted per household annually, or 7.79 tons over ten years $5.78 per ton cost
A look at one of the high tech food scrap processing units Princeton University has been using for the past 12 years…
Cost: $12/day (Savings of over $20,000 each year)
Guiguinto, Bulacan, Philippines - Eco-boys" in pedicabs (bicycles with a side car) collect about 1/2 ton day for sale to rice farmers after static pile composting The Pedal People Cooperative, Inc., Provides collection in Northampton, Florence and Leeds, Mass.by bicycles pulling trailers Eleven worker/owners have built collection program to include 311 households and 23 small businesses Organics collection for 87 sites (began in 2007)
Professionally managed, any material can be composted with an outdoor, open-windrow process at any location without public nuisance or negative environmental impact.
