Top 10: Best Kitchen Sink Waste Disposal Units Review 2017

Kitchen Sink Waste Disposal Units are generally placed under a kitchen sink, in between the drain and the pipe. These are electrically powered and shred the food and other wastes into tiny pieces so that they do not cause any blockage in the plumbing. They are available in a number of design and price ranges. Sink waste disposers not only make waste disposal easier, but also reduce environmental damages. Given that sink wastes account for 20% of the total household waste, installing a kitchen sink waste disposal unit would be a great investment.

How does a sink waste disposal unit work?

A sink waste disposal unit contains a chamber for collecting food wastes. Rotating blades then cut these into tiny little pieces. The chambers are usually enclosed with rubber casings to prevent the food from flying back and insulating noise. There are mainly two types of waste disposers – the continuous feed and the batch feed. In the continuous feed disposers, waste materials are dropped in after the machine is set to work while in the continuous feed machine, waste materials are placed in batches during the operation.
