In 2019, ecomaine, waste manager for 400,000 people in Maine, along with four municipal partners, piloted an internship program to address costly recycling contamination. Before heading out into the communities, interns received a deep dive training into the waste hierarchy and the recent changes to the recycling market. Over 8 weeks, interns tagged recycling bins and provided residents with educational materials on proper recycling that utilized community-based social marketing principles.
