Well, the obvious thing is don’t pour it down the sink. I noticed a blurb in the Holt Community News today about a recycling program in Eaton County.
Used cooking oil recovery is available at the following locations throughout Eaton County: The Charlotte Area Recycling Authority, the Delta Township Recycling Center, the Grand Ledge Recycling Center, the Mulliken Recycling Center and the Sunfield REcycling Center. To dispose of used cooking oil, save it in a clean container with a tight-fitting lid, then carefuly pour the oil into the tank located at each site. Take your container home, clean it, and reuse it for the same purpose. Contact the Department of Resource Recovery for more information, (517) 5434-3686.
