Boycott Your Garbage Disposal - It has a Huge Carbon Footprint

Like kitty liter and all flushable products, the eggshells, coffee grounds and other refuse from in-sink disposals have to be removed from wastewater before biological treatment. It settles to the bottom of our primary clarifier and then we pump the sludge to a heated tank where it is digested, dewatered, then trucked to the Central Valley as fertilizer – a very energy-and fuel-intensive process. Smaller food particles that do not settle out in our clarifier also use more energy because it’s difficult for our microorganisms to digest them. More microbes working harder need more oxygen which means more energy cost to run the blowers that aerate our tanks. Please compost kitchen scraps or put them in the trash.Like kitty liter and all flushable products, the eggshells, coffee grounds and other refuse from in-sink disposals have to be removed from wastewater before biological treatment.
