Garbage disposals are unfriendly to the environment mainly because of the excess food waste that is pushed out to water treatment plants, states Everyday Health. The energy required for the treatment plant to clean the water is much more than if the food waste was not involved, says Planet Green.
Composting what normally is placed down the garbage disposal is a good start in becoming environmentally smart. Planet Green suggests using the compost to fertilize a garden full of fruits and vegetables. Another suggestion is to feed the excess food to pets or farm animals.
Fat-filled and oily foods should not be placed down the garbage disposal, says Planet Green. Placing it in the trash is the best choice.
