Chicago-based Lakeshore Recycling System is the first company in the U.S. to install a new “self-aware” machine that sorts through recycled materials.

Empty yogurt cartons, peanut butter jars and pizza boxes: How clean do they need to be in order to toss them in your recycling bin? Chicago’s recycling staff has answers.

From lost jewelry to criminal evidence, a Pontiac landfill that receives trash from Chicago has plenty of bizarre waste stories. 

About 5,000 tons of trash from the Chicago area is dumped every day at a landfill in Livingston County, but hardly any of it goes to waste. How yesterday’s trash becomes tomorrow’s energy.
