Question: Am I better off feeding my leftover mashed potatoes into the garbage disposal, so they don’t end up in a landfill or should I throw them in the trash can, so they don’t end up the water supply?
Royce Hammitt, Operations & Maintenance Manager at Des Moines Metropolitan Wastewater Reclamation Authority, explains options for disposal of your leftover holiday feast, from best for the environment to the worst.
Prevent food waste before it is created.
Donate fresh, wholesome food to those in need.
Feed safe, fresh food scraps to animals.
Turn food waste into a valuable soil amendment utilizing a backyard composter.
Sewer Disposal vs. Landfill
Food waste contains fats, oil, and grease which can coat and block sewers leading to sewer overflows. Sending food waste to landfills may produce methane gas, a potent greenhouse gas which can escape to the atmosphere. Fortunately, Metro Waste Authority captures methane and utilizes it to produce green electricity.
