Recently, the National Association of Home Builders created the National Green Building Standard which provides a point scale for rating green building in new homes. Garbage disposals installed in sinks count for one point in this new rating system. Here at Regent Homes, garbage disposals are standard features in all our homes, for convenience and for the green benefits.
How is a garbage disposal green? Opinions vary about the virtues of garbage disposals, but here in the Pacific Northwest they make sense for several reasons. While the greenest option for dealing with food waste is composting, not all of us have the room for a compost pile or bin in our yards, and our cool climate makes the decomposition process move more slowly. If composting is not an option, then the choice is between putting food waste in the trash or in garbage disposal, and at least in our area the disposal is the way to go.
Food waste put in the trash will have to be hauled away by garbage truck to the dump, where food put down the disposal will be carried by the sewer water to the water treatment facility and the disposal itself only uses a very small amount of electricity. Once at the water treatment facility, the food waste will be treated, and almost all of the local water treatment facilities convert the solids into fertilizer. Most facilities here also capture the gas released by the process and use it for power, which keeps that methane from escaping into the atmosphere.
Keeping your disposal in good working order is also important, to extend the life of the appliance before it needs to be replaced. Blades can be kept sharp by putting a few ice cubes down the disposal. To keep the disposal clean, run hot soapy water through the disposal every day. Additionally, most disposals are not built to handle animal bones, these should be put in the trash. It’s also important not to put grease or fats in a disposal, as they can solidify and cause clogs within your home’s plumbing or the sewer system.
