Food waste disposers (FWDs) in domestic sinks are banned or self regulated in most local communities in Japan. The ban is based on the belief that the direct discharge of raw organic wastes will increase water consumption, impact sludge management, and during wet weather will increase inflow loads to combined sewer systems causing overflow water to spill into water bodies.
In an aging society one assumption is that FWDs will lead to the decrease of solid waste levels and improve general living standards. However, what will be the effect of FWDs on the environment?
The introduction of FWDs to support a sustainable recycling program covering all facets of society requires careful selection of a system which complements the infrastructure. Building codes and local and regional characteristics must also be assessed, including the impact on users, garbage collection and disposal, and waste water systems.
Ogasawara Village on Bonin Island, a part of Tokyo, was chosen for this study. In this simulation, it will be assumed that FWDs are installed in every residence on the island. This analysis is designed to assess the impact of FWDs on garbage and disposal systems, wastewater treatment plants, and other environmental issues. Finally the effect of FWDs on the economy, quantity of heat, energy consumption and CO2 emission levels will be analyzed.
