Waste composition studies (a.k.a. "waste audits") come in all shapes and sizes to serve a range of purposes and budgets. But whether an audit results in meaningful information or just a report gathering dust depends on the way it's carried out. Factors like which collection streams to sample and how sorting categories are defined become critical to ensuring the right data for effective program planning. This webinar will feature industry experts reviewing best practices to design audits, starting by identifying project outcomes and the questions that composition data needs to answer. The presenters will also cite case study examples from residential, institutional, commercial and other settings, showing how audit data was analyzed to guide diversion and upstream decisions.
