Recycling Evaluation ToolsRecycling Evaluation ToolsTracks costs & quantities of recycled and/or disposed materials
Waste audits show cost-effectiveness of recycling & waste reduction◦ Record feedback on program success or failure◦ Short Audit: Conducted monthly, taking 15 minutes
each time◦ Full Audit: Conducted once during project, at
quarter or third points, taking approx. 1 hour
