Only 1 percent of water on earth is fresh and available

Reduce energy and water needs

 

Use a garbage disposal sparingly to minimize energy and water use. 

Garbage disposals connect to the sewer system and food waste will eventually get recycled through the wastewater treatment plants as biosolids soil amendment.

However, running a garbage disposal requires water and electricity, after the food goes down the drain even more water and electricity will be used to move the water and clean the food out and truck it to farms and forests.

Helpful hint: When trying to recycle food waste, choose an option that is the most efficient, local, and uses the least energy:

1) Compost at home
2) Put food scraps in your green yard waste bins
3) Use the garbage disposal

Did you know? Food in the trash never gets recycled and creates more greenhouse gases at the landfill.
