Even though per capita waste generation declined from 12.9 lbs/day in 2006, so has the share of recycled waste, from 41% in 2006 to 36% in 2009 (CMAP, 2008b; IEPA, 2011). Moreover, waste collection costs remain much higher than average. The presence of IRS also induces other firms to locate there, as people come in search of higher wages, job opportunities and cultural values. This self-reinforcing process contributes to, inter alia, the formation of deeper, more efficient factor markets and more active generation and dissemination of knowledge.
