Research shows garbage disposal use may benefit the environment.
Food waste can be a large contributor to issues related to solid waste management. Studies have shown that when households use garbage disposals to dispose of food scraps, the overall volume of waste taken to landfills may decrease, lessening the environmental impact of food-related waste.?
Environmental Benefits Reporting
Reports highlight the impact of disposals on the environment and?waste management.
This comprehensive document includes a collection of findings regarding all facets of waste collection, treatment and disposal process, organizing the information according to major concerns and assumptions regarding garbage disposers. Included are 50 research references: 41 recent studies, three executive summaries, two literature reviews, one textbook, two specifications and requirements, plus one internal calculation.
LCA Research Report
LCA Research report reveals how food waste disposal impacts the environment.
A Life Cycle Assessment (LCA) was developed to study the environmental impact of food waste disposal systems. This study examines various methods of transferring and disposing of organic food waste while measuring global warming potential and primary energy demand of each process. The final and complete Life Cycle Assessment report provides an in-depth study of how various food waste disposal processes affects our planet.
Capable Treatment Plants
The capabilities of U.S. wastewater treatment facilities vary by location.
This report includes a partial list of U.S. wastewater treatment plants and their associated capabilities, which is based on information collected from the websites of each listed facility. For the most complete, accurate and up-to-date information, please check with your local wastewater authority.
Life Cycle Comparison
Life cycle report compares benefits and?costs of 5 food waste disposal methods.
The National Association of Heating, Plumbing and Cooling Contractors commissioned a life-cycle comparison of five engineered systems for managing food waste: sending food waste through a disposal to a wastewater treatment plant; collecting food waste with municipal solid waste and then sending it to a landfill, a community compost facility or a central incineration facility; and sending food waste through a disposal to a septic system. The study considered the required land, total system energy, total system materials, total emissions and system costs for each method.
Disposals in NYC
NYC discovers the benefits of disposals to solid waste management and?operating budgets.
New York City officials commissioned a study of the impact of garbage disposals in the city’s Department of Sanitation (DOS). The study revealed the potential for disposals to make a positive impact on NYC residential waste management. According to data collected, disposals divert about 3% of total household solid waste. If it is assumed that 38% of the NYC households are equipped with garbage disposals by 2035 and that the average equipped household places 50% of food waste into disposals, the city would save $4 million in solid waste export costs.
