How It Works
After-dinner garbage removal
can be lightning-quick with a well-maintained garbage
disposal. It’s installed under the kitchen sink and equipped with a set
of rotating grinders - or blades - to grind food material before it enters the
waste disposal lines. The garbage disposal - also known as the insinkerator - is electrically powered and operated with
a wall mounted switch.
What Can Go Wrong?
The most common problem you’ll run into with a garbage disposal is a jammed up mechanism; Grinding up
a couple pounds of stringy celery or dropping a spoon into an active garbage
disposal may cause temporary failure. Carefully dislodge any accumulated
materials before operating your garbage disposal to avoid motor failure.
Garbage disposal size varies
between one-third and one horsepower. One-third horsepower models are best
suited for small households with infrequent meal preparation. Three-quarter to
one horsepower units are generally found in larger households with larger
amounts of waste. A 700-watt garbage disposal,
run for a minute per day, uses about 4.2 kilowatt-hours annually, producing
approximately 6.5 pounds of carbon dioxide (CO2).
Garbage disposals reduce the
amount of waste that is added to landfills. Instead, disposed food waste is
sent to treatment plants where it can be turned into an energy source.
