Casper residents should think twice before tossing yard clippings in the garbage. In May, the city will begin implementing its ban on putting yard waste in dumpsters to be landfilledas a cost cutting measure.

Casper has a composting program that turns yard waste into wood chips and compost for soil, but branches, grass, leaves and other organic matter still make up about 18-percent of what the city pays to put in the landfill.
