A score of 100 means a state's law lets every material be used as a manufacturing feedstock, without a waste permit and without ever being classified as waste or sent to "disposal". Select a state for its scorecard.
The filled part of each bar is what today's law allows; the rest is the distance to a law built for circular manufacturing.
Each reform gives every state full marks on one test. Turn them on to see how the national picture moves.
The index is an editorial yardstick: it measures each state's law against one goal, a framework in which materials directed to manufacturing are feedstock rather than waste. Every input is a field in the state's sourced legal profile (the 12-material feedstock review, the solid-waste permit review and the governing law), and each state's scorecard links to those sources. The research itself describes the law neutrally; only this page scores it.

Where sources do not settle a question the test scores zero, because the law gives no assurance; territories with thin sources score low partly for that reason. Scores update automatically when new research is published.
The site's sponsor works in circular manufacturing. The index applies the same published rules to every state, and every point traces to a cited statute, rule or source.
