A single concert at a nearly 3,000 seat venue like Pepsi Amphitheater in Flagstaff might generate well over a thousand pounds of trash. Tyler Linner, a master’s student at Northern Arizona University, wants to find creative ways to recycle as much of that trash as possible. KNAU spoke with him a year ago about his start-up project to reuse the broken plastic sleds that litter the forests in the winter. Now he has a business called Praxis Waste Solutions in a small warehouse near Buffalo Park, where he’s literally sorting through garbage to see how it can be salvaged. KNAU’s Melissa Sevigny spoke with him there.
