This document outlines various policy mechanisms that can be implemented to control single-use plastics and promote a circular economy. It categorizes the mechanisms into those that regulate product manufacture, sale, use, repair/reuse/repurposing, disposal, and raw material extraction. Examples of mechanisms listed include requiring reusable products for on-site dining and events, banning certain single-use plastic materials, incentivizing domestic production and recycling, and educating the public. The overall goal is to shift from a linear take-make-waste model to a circular economy with reuse and recycling of resources.
