Why You Shouldn’t Put Watermelon Rinds Down Garbage Disposal

Many food products should not go down your garbage disposals, such as rubbery or fibrous foods, tough meat, bones, and other hard food detritus. Watermelon rinds fall into the category of hard food detritus. 

When hard food detritus is tangled in the impellers of your disposal, it is really hard for the disposal to grind it up. Putting the watermelon rinds may harm the lugs and overheat the disposal motor.

They may also get stuck in the system for a long time, causing the disposal to malfunction.

How Garbage Disposals Work

You may see garbage disposals as high-powered, sharp-bladed machines capable of crushing any waste material into a paste, but that is incorrect. There is a metal chamber within the machine with a circular plate containing two swiveling metal lungs called impellers. 

This mechanism is driven by a motor underneath it that pulverizes the food waste into a paste and leads it into the pipes. Pouring the wrong things into the disposal may wear out the impellers or wind around the machinery and damage the motor.

3 Food Waste That Should Not Be Put In Garbage Disposal

Here is a list of food waste that you should not put into the garbage disposal:

Cooked Meat/Bones

Pouring strong meat that has bones down the drain into the disposal is a terrible idea. The garbage disposals are not designed to break down substances like bones and other hard materials. This may damage the disposal completely.


Grease and oil from frying cool down and clog up when they get into the garbage disposal. Every food material you place into the disposal will stick to the thick grease sludge until the whole system is blocked. The grease weighs down the motors until it causes damage.


It is a well-known culinary fact that Pasta swells when exposed to moisture or water. If you get pasta down the garbage disposal, the impellers may find it difficult to grind it effectively, leaving residue. When water flows down the sink, as it always does, the pasta residue swells and causes a blockage in the system.
