Transforming Urban Waste: Policy, Innovation, and the Path to Sustainability

Waste management and treatment is an ever-growing issue, influenced by consumerism trends, continued urbanization, and rising public awareness. Tackling this issue will require significant innovative thinking, both from policymakers and the technological sector. Join the Research Program on Sustainability Policy and Management, the MS Program in Sustainability Management, the MS Program in Sustainability Science, and the MPA Program in Environmental Science and Policy for a conversation about the role of urban policy at the municipal, state, and federal levels, as well as new technological approaches in shaping effective solutions for the future of waste management in New York City and beyond.
