The Solid Waste Association of North America (SWANA) Applied Research Foundation released a report concluding that: a significant amount of additional food waste processing capacity will be required to achieve national, state, provincial, and local food waste diversion goals. The report also emphasizes the need for local decision-making in selecting and implementing those food waste diversion programs.

a significant amount of additional food waste processing capacity will be required to achieve national, state, provincial, and local food waste diversion goals. The report also emphasizes the need for local decision-making in selecting and implementing those food waste diversion programs.

The report goes on to say that interest in recovering food waste from municipal solid waste is growing to meet goals established by the U.S. Environmental Protection Agency and U.S. Department of Agriculture, but many major metropolitan areas lack the infrastructure to manage the ability to meet the established goals. Two examples were cited:

Several states, including Massachusetts and Connecticut, condition their food waste diversion requirements on the ability of generators to access adequate capacity within a certain distance.

Speaking as SWANA’s Executive Director and CEO David Biderman stated:

We believe that Americans need to rethink how food is handled before it is considered waste, to divert it into programs to feed people, and to find other productive uses for food as food. Once it becomes waste, however, municipal decision-makers, working with their processing partners, need to determine how to best manage the material.

The SWANA report focuses on the effects of food recovery at the two lowest tiers of the hierarchy – composting and landfilling/incineration. The report concludes that food waste diverted from landfill operations has the potential to be processed at composting facilities. Then, going on to say that anaerobic digestion (AD) and co-digestion at wastewater treatment facilities are also likely destinations for diverted food waste.

Jeremy O’Brien, Director of the Applied Research Foundation, noted:

The food recovery hierarchy does not apply universally; an analysis of greenhouse gas impacts based on local data and conditions is needed to identify the best food scraps management options for a specific community.


The report encourages solid waste managers to perform a life cycle analysis of economic and environmental costs and benefits based on local needs, system capabilities, and data to identify the most effective ways to manage food waste at the local level.

SCS Engineers and SWANA are both long-time advocates for local decision-making in establishing programs to collect and manage municipal solid waste.

SCS Engineers will evaluate the collection, hauling, and processing of organic material and food waste for Placer County, California in compliance with the state's mandatory organics recycling law.
Placer County, California


SCS Engineers will evaluate the collection, hauling, and processing of organic material and food waste for Placer County in compliance with California’s recently adopted mandatory organics recycling law. According to the California Department of Resources Recycling and Recovery, the state disposes of approximately 30 million tons of waste in landfills each year, of which more than 30 percent could be used for compost or mulch.

Composting is a viable and important technology for managing organic wastes, as are modern landfills with comprehensive landfill gas collection and utilization systems. Both of these approaches have different capabilities and limitations. Understanding the facets of each approach allows individual communities to make waste management decisions, based on facts by environmental engineers that are beneficial for both human health and the environment.

SCS recently authored a report for the Metro Waste Authority in Des Moines, Iowa regarding their yard waste compost operations. Metro Waste’s yard waste compost system includes a bag and sticker program to support separate yard waste collection, shredding, screening, and windrow composting at the Metro Compost Center, which is co-located atop a closed City of Des Moines Landfill, and at the active Metro Park East Landfill.

The SCS report evaluated the costs, greenhouse gas emissions, carbon sequestration, and the advantages and the disadvantages of continuing their current operations or alternatively considering a partial or full closing of the compost operations. If operations are reduced or stopped, these materials would be disposed of in the active municipal solid waste landfill. The active landfill has a comprehensive gas collection system, and Waste Management owns and operates an 11.2 Megawatt landfill gas-to-energy facility at the landfill.

The report was used by the Metro Waste Authority in early 2015 to support an amendment to Iowa’s solid waste regulations. The amendment allows for yard waste to be disposed of and be managed in landfills, only if the landfill has an active landfill gas collection and control system with a landfill gas-to-energy facility to effectively control and reduce methane emissions. The legislation was passed as a restricted exemption to the State’s ban on yard waste disposal in landfills. The amendment in the State’s regulations provides landfill operators some flexibility in managing these types of materials, as other states have done as well.

Most media channels fully informed their readers of the science and function of both technologies, explaining that when considering all factors, one landfill operation can reap greater environmental benefits than another operation despite using the same solution. Some organizations view the law and the report prepared by SCS as “anti” composting, or that because SCS’s investigative analysis and report proposed options, SCS does not support composting. SCS Engineers fully supports composting. In fact, we design, permit, and operate compost facilities around the nation.
