During the Talking Trash Expedition at The Greene School students explore one of the most important environmental problem we face as a society, waste. Case-studies in this expedition explore various types of waste including organic, municipal and toxic. Fieldwork for the expedition includes visiting a local wastewater treatment facility, the Rhode Island Resource Recovery Corporation, and an industrial compost farm. Additionally, honors students attend a state-wide compost conference where they learn about the logistics behind organizing a waste-focused organizational event. The final product is a Waste Solutions summit hosted by the Greene School at Groundwork Rhode Island in Providence.
