A May 31 column on the Product Policy Institute blog, by North Carolina Recycling Program Director Scott Mouw, Running to stand still: Why the current municipal recycling system can’t deliver the goods, looks at recycling and extended producer responsibility (EPR) and asks: "In a classic capitalistic system, when demand rises, economic law dictates that suppliers will respond. So why does this basic tenet appear not to work in the U.S. recycling system? Why can’t our current municipal recycling programs keep up with rising demand? And why have material recovery rates essentially stagnated?"
