How is waste management leading the way in composting?

Waste Management is leading the way by developing advanced commercial compost facilities that create high quality compost and soil amendment products at the 40 large-scale composting facilities we operate across the US. Composting diverts organic material away from landfills and into facilities where it can be put to use.
