Determining the Chemical Composition of Toner Used by ASU Photocopiers

This project seeks to analyze the physical properties and chemical composition of the toner used by ASU photocopying machines. Because current paper recycling processes require toner to be removed from paper, the manufacturing of recycled paper is expensive and can result in more greenhouse gas emissions than newly manufactured paper. There is growing interest in recycling processes that could allow toner to more easily separate from printed materials. Understanding toner compositions is critical in determining the recyclability of printed materials. By studying the toner formulation used by public ASU photocopiers, this project aims to directly influence university purchasing and recycling practices.
