Promoting the transition from the linear system of 'take-make-dispose' to a closed-loop system where materials are reused continuously, Zero Waste advocates aim to conserve resources, protect health through material recovery, and improve the equity of material distribution. While the philosophy of Zero Waste is often commended for its comprehensive consideration of the environmental, social, and economic factors of waste, the movement has largely relied on a single indicator -- diversion rate -- to measure and guide progress. Diversion rates quantify the percentage of materials diverted from landfills or incinerators. For Zero Waste advocates, the goal is 90-100 percent diversion, which implies a very closed loop of material recovery. However, the term 'diversion' often describes a range of activities, such as reuse, recycling, and composting without any indication of whether materials are being diverted temporarily or indefinitely. This thesis uses a comparative case analysis to determine the strengths and limitations of the diversion rate as the primary performance indicator for Zero Waste in the management of municipal solid waste. Using semi-structured interviews with key informants and archival documents, the report compares Los Angeles and New York City, two cities that established diversion rate mandates more than 25 years ago and recently adopted Zero Waste goals. By analyzing the development of diversion activities in these two locations, the thesis establishes the need for more holistic evaluative methods and proposes upstream strategies to help municipalities transition to a sustainable, closed loop system. === by Jennifer M.
