The ideal material of a garbage disposal is stainless steel. Stainless steel garbage disposals are preferred because they are more durable and last longer than other types of garbage disposals, like plastic.
Stainless steel garbage disposals cost more than other types of garbage disposals. The cheapest type of garbage disposal is plastic but it's more likely to break faster than higher-quality stainless steel garbage disposals.
Garbage disposals actually offer many environmental benefits. They reduce the quantity of food waste by grinding them down and sending them through the home's plumbing system. Garbage disposals also reduce food bacteria in the home. When maintained properly, they can also make it easier to clean the kitchen.
