The first method was created as a result of a statewide law known as Returnable Container Legislation (or ‘‘Bottle Bills’’) originally enacted in 1982, which established a redemption value on
carbonated beverage. Some studies showed that this deposit system is useful for reducing total roadside litter by between 30%
and 64% (Container Recycling Institute, 2005), and the recycling
rate of PET bottle in state with this legislation is much higher than that without it (Gitlitz and Franklin, 2006). However, the US beverage container industry, grocery stores, and convenience stores are often against the introduction of both new and amended beverage container deposit legislation as it damaged the convenience of individuals. In 1997, there were 10 states with this legislation, while in 2008, the number only increased from 10 to 11 (NAPCOR, 1997; Container Recycling Institute, 2005).
The second method is the most widely accessible collection method, named curbside collection. NAPCOR indicated that approximately 55% of the PET plastic containers collected for recy-cling are generated through curbside programs (NAPCOR, 1997). Though the curbside collection is the most convenient method for residents in the United States, it generally requests residents to separate designated recyclables from their household garbage. Because there are no incentives for sorting and collecting PET bot-tles, the activities for source separate collection of PET bottles are
based on the individuals’ initiative behavior. As a result, the quality
