Having garbage disposal serves several purposes in the family kitchen. Having a good one serves even more. By grinding your food waste instead of taking it out to the trash, you are not only saving a trip or two, but you are helping to keep nocturnal animals away from your neighborhood living spaces. In addition to this, sending liquefied food waste to the county water treatment plant will allow them to process it, so it can be recycled into bio-solids, and used for fertilizer or methane energy. When you consider how little disposals cost to own and operate, it just makes no sense to have one. They come in two styles — continuous feed and batch feed. Continuous feed is the most common that allows you to continue placing items in while it is running, and the batch feed model requires you to fill the chamber, put a lid on, and press a button to finish. Some of the other features to watch out for include anti-vibration technology and sound buffering. All of the models on our list will include both, so if you choose one from this list, you are safe and sound. Lastly, if you live with a septic tank, then make sure your chosen model will liquefy the waste, to help keep your tank in good working order. Only one listed here has a lifetime warranty, and the others will have anywhere from two to seven-year warranties.
