A trash compactor is often used by business and public places like hospitals (And in the United States also by homes) to reduce the volume of trash they produce. A baler-wrapper compactor is often used for making compact and wrapped bales in order to improve logistics. [1] Normally powered by hydraulics, compactors take many shapes and sizes.
In the United States, 50% of homes had disposal units as of 2009, [12] compared with only 6% in the United Kingdom [13] and 3% in Canada. [14]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.

A variation of the centrifugal switch used a changeover contact to ensure that the auxiliary windings remain in the circuit through a running capacitor. These motors are called two-value or capacitor start capacitor run motors. Centrifugal switches are found in many clothes dryers, supplying power to the motor in parallel with the start switch ...
Loose, non-compacted trash occupies up to 20 times more dumpster space than compacted waste. Waste haulage costs are reduced by fewer or smaller dumpsters, and dumpster pickup frequency can be reduced by 50 percent. A side effect of waste compaction is that important items, like evidence in a crime, may be difficult to recover from the garbage.

A centrifugal clutch shown in a patent application, 1898. Centrifugal clutches were used in railway locomotives before 1858, [1] and referred to (in relation to electric motors) in a patent of 1899. [2] A patent was issued in the United States for an automotive centrifugal clutch (on an electric vehicle) in 1898. [3]

Centrifugal governors are used in many modern repeating watches to limit the speed of the striking train, so the repeater does not run too quickly. Another kind of centrifugal governor consists of a pair of masses on a spindle inside a cylinder, the masses or the cylinder being coated with pads, somewhat like a centrifugal clutch or a drum brake.
