Commercial Organics Collection

"Retro" Approach Yields Cost Savings

Bart Carr, Central Contra Costa (CA) Solid Waste Authority

The CCCSWA has adopted a "retro" recycling approach to collecting commercial food waste to help reduce costs. Instead of collecting food waste comingled with other organic (or non-organic) materials, the CCCSWA program relies of the old recycling approach of source separation to provide uncontaminated food waste that can be committed to anaerobic digesters for processing. Called the "Food Recycling Project", commercial food waste collection began in 2009 as a pilot program with the East bay Municipal Utility District (EBMUD) and Allied waste/Republic Services in several east San Francisco Bay communities. The CCCSWA approach, which differentiates it from a similar San Francisco program also using EBMUD digestion, is to ask commercial food generators to exclusively provide food waste (pre-served is preferred but plate scrapings are also accepted) which is collected by Allied/Republic and taken to a nearby transfer station for grinding to reduce particle size. It is then delivered to the EBMUD facility where the food waste is digested with bio solids and eventually contributes to production of green electricity. The "retro" source separation approach avoids expensive clean up processes prior to digestion. The result is a commercial food recycling program with a per ton cost that is very competitive with windrow composting!

Food Waste Generator Audits And Analysis

Anne Brantley, Wastequip

Food waste comprises 14% of municipal solid waste, making it the largest single component of the waste stream with 34 million tons generated annually. Less than 3% of that waste is recovered. Food waste presents a number of environmental challenges for commercial food waste generators including restaurants, cafeterias, supermarkets and food processors as well as haulers. Among these concerns are odors, attraction of insects and rodents, employee safety and responsible, sustainable disposal. Haulers are challenged by route logistics, lack of infrastructure for food waste disposal and growing environmental regulations. Wastequip has developed Organics2Go, a program for commercial food waste generators and haulers that addresses the safe, efficient collection, storage and transport of organic waste. Presentation will discuss how to use data from waste audits and other on-site considerations (employee safety, product shrinkage, facility/store appearance and odor) to design an appropriate system for addressing customers' food waste collection needs including specially designed steel or plastic containers, carts, cart lifters, biofiltration systems and food waste digesters.

Meeting The Challenges Of Food Waste Collection

Phil Holloway, Environmental Products & Services of Vermont, Inc.

Working with the largest grocery store chain in the United States has provided us with many challenges in the food scrap recycling sector.

Challenge one: Working directly with the customer's locations to facilitate donations first (reduce) benefits everyone. Numerous challenges include Employee issues such as turnover, and morale. Others include customer quirks such as scheduling and frequency, and then, we have donation agency issues, such as, what is acceptable, what system works, and what doesn't. Paying attention takes up a lot of time even before we begin the recycling!

Challenge two: Working with equipment suppliers to have the highest quality storage equipment for handling source separated food scraps. The industry has only recently produced more acceptable and enduring products for source separated organics. Still, not everyone understands that Food scraps are NOT solid waste. How we choose the container for onsite storage and handling makes for a successful diversion program.

Challenge three: Working with processing facilities to ensure a successful program. The lack of processing has lead to the utilization of animal feed as an in between for compost and anaerobic digester locations. How this has been not easily accepted in the recycling world and making it work is the most challenging part of the program.

Challenge Four: Working within a regulatory framework that doesn't separate out food scraps from other solid waste. We will discuss this at length and even today there is so resistance to change, especially at the State level.

Evolution Of A Commercial Organics Composting Program

Paul de Block, Portland (OR) Bureau of Planning & Sustainability

Over 900 business locations currently participate in Portland's food scrap collection program. Initial targeted outreach was conducted in 2005-06 where messages and tools/resources were developed. Since then, the approach has been largely reactive but there are plans in place toward mandatory participation of large food scrap generators.

Residential Source Separated Organics

Residential Food Waste Collection in the U.S.

Rhodes Yepsen, Novamont NA

A look at the development of residential food waste collection in the U.S. overtime, with attention to geography (California and Washington state leading the way), political drivers (landfill bans, recycling goals and mandates), economic factors (landfill and incinerator tip fees), and planning (kitchen pails, compostable bags, collection frequency, etc.). Comparisons will also be drawn between food waste collection in the U.S. and other countries, identifying trends and tips for successful programs.

Rolling Out A Residential Program

Servicing Residential SSO Programs

Jordan Trimmer, Pacific Region Compost/Republic

The Road Ahead will cover the history and future of a Pacific Northwest compost facility. Throughout Western Oregon, source separated organics and compost programs have been gaining momentum. Allied Waste and its composting facility, Pacific Region Compost, have tried to stay ahead of the trend and help guide these programs into the future. This presentation will highlight some of the history of Allied Waste?s organics program, as well as share some of the lessons learned along the way.

Building SSO Participation In Multifamily Program

Alexa Kielty, San Francisco Department of Environment

Composting in Apartments: How San Francisco is Rolling Out Organics Collection in the Most Challenging Places. Even before the Mandatory Recycling and Composting Ordinance passed in October 2009, San Francisco's Department of Environment staff put together a comprehensive outreach strategy to move towards a successful model of composting in some of San Francisco's most challenging Multi-Family Dwellings. With the help of Spanish and Chinese speakers from the Environment Now Outreach team, SF Environment's Green Apartments campaign uses a "door to door" strategy, teaching apartment residents ? face to face ? how to separate their organics. Find out why San Francisco has taken this approach and how they have over 6,000 apartments composting, even in the Tenderloin.

Municipal Compostable Products Guidelines

Compostable Bioplastic Testing Protocols

Hillary Near, Cascadia Consulting Group

This presentation will share the results of a project to develop protocols for testing the compostability of bioplastics that are marketed as compostable. The goal of the project is to identify procedures for real-world testing of the compostability of bioplastic food service and packing materials in multiple composting technologies. The results of these tests will guide compostable plastics purchasing decisions by the City of San Jose.

The research portion of this project included surveying major commercial composting facilities in California which process compostable bioplastics to identify existing testing protocols, processing methods (windrow, aerated static pile, plastic bagged, in-building, and others), and handling procedures (identifying loads, dedicated piles, pre-composting contaminant removal, processing methods, post-composting contaminant removal, and others). In 2012, the project will engage a number of commercial composting facilities in real-world compostability testing of compostable bioplastic foodservice ware and packaging material. This project is being funded by the City of San Jose Environmental Services Department, Allied Waste Service's Newby Island Resource Recovery Park, and Zanker Road Resource Recovery Facility. This presentation will summarize the results of the testing and will include: Results of the survey of existing testing protocols; and Recommended best handling practices for compostable bioplastics.

Regional Workgroup Guidance On Compostable Products

Justin Gast, Washington County (OR)

Inspired by a U.S. Composting Council presentation on bioplastics, and based on discussions with in-state composters, the Oregon Department of Environmental Quality recently convened a regional organics workgroup made up of local jurisdictions and composters to address potential issues involving the acceptance of compostable foodservice ware in the local commercial organics material.
