Overview
Transitioning to a more circular economy where materials are recycled to reduce pollution and create further value is central to human prosperity and environmental responsibility. However, this transition presents several challenges that require innovative solutions.
The Casella Center for Circular Economy and Sustainability brings together leading scientists, engineers and waste management sector experts to address these challenges. It builds on three decades of collaboration between UVM and Casella Waste Systems, Inc. on research to reduce the environmental impact of waste. These efforts include decreasing greenhouse gas emissions from waste management systems, assessing and mitigating emerging contaminants that can pose obstacles to circularity, and life cycle assessments to clarify environmental costs and benefits.
