Garbage disposal unit

A garbage disposal unit (also known as a waste disposal unit, food waste disposer (FWD), in-sink macerator, garbage disposer, or garburator) is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The device shreds food waste into pieces small enough—generally less than 2 mm (0.079 in) in diameter—to pass through plumbing.

The garbage disposal unit was invented in 1927 by John W. Hammes, an architect working in Racine, Wisconsin. He applied for a patent in 1933 that was issued in 1935. His InSinkErator company put his disposer on the market in 1940.[citation needed]

Hammes' claim is disputed, as General Electric introduced a garbage disposal unit in 1935, known as the Disposall.

In many cities in the United States in the 1930s and the 1940s, the municipal sewage system had regulations prohibiting placing food waste (garbage) into the system. InSinkErator spent considerable effort, and was highly successful in convincing many localities to rescind these prohibitions.

Many localities in the United States prohibited the use of disposers. For many years, garbage disposers were illegal in New York City because of a perceived threat of damage to the city's sewer system. After a 21-month study with the NYC Department of Environmental Protection, the ban was rescinded in 1997 by local law 1997/071, which amended section 24-518.1, NYC Administrative Code.

In 2008, the city of Raleigh, North Carolina attempted a ban on the replacement and installation of garbage disposers, which also extended to outlying towns sharing the city's municipal sewage system, but rescinded the ban one month later.

In the United States, 50% of homes had disposal units as of 2009, compared with only 6% in the United Kingdom and 3% in Canada.

In Britain, Worcestershire County Council and Herefordshire Council started to subsidize the purchase of garbage disposal units in 2005, in order to reduce the amount of waste going to landfill and the carbon footprint of garbage runs. However, the use of macerators was banned for non-household premises in Scotland in 2016 in non-rural areas where food waste collection is available, and banned in Northern Ireland in 2017. They are expected to be banned for businesses in England and Wales in 2023.[needs update] The intention is to reduce water use.[citation needed]
