Decomposition analysis for Toxic Chemical Emission Changes in U.S. Manufacturing Sectors from 2001 to 2019

A circular economy is an economic system that is restorative and regenerative by design. A circular chemistry aims at fully using and recycling all the materials and products even from atom level is critical for building a circular economy. So it's important to find how industries managed with chemical substances. In this research, we clarify how different factors effect the toxic chemical emissions and how they help the manufacturing sectors to move towards to a circular chemistry in recent years. We can also find which chemicals are easy or hard to be designed into a circular chemistry.
