Most Americans have access to some sort of recycling program. However, the rules, practices and community norms around recycling vary considerably from place to place, contributing to dramatically different local recycling levels. People who live in places where social norms strongly encourage recycling are more likely to be aware of recycling rules, say they have more options for recycling, and see more of the waste they generate being recycled rather than landfilled, according to a new Pew Research Center survey.
The survey, part of a study covering issues involving climate change, energy and the environment, found that about three-in-ten Americans (28%) say their local community’s social norms strongly encourage recycling and re-use. About a fifth (22%) say most people in their communities don’t really encourage recycling; the remaining half live in places where, they say, norms around recycling are somewhere in the middle.
A recent study conducted for the Sustainable Packaging Coalition, an industry group, estimated that 94% of the U.S. population has some type of recycling program available to them: About 30% have curbside collection only, 43% have both curbside service and drop-off centers and 21% have drop-off programs only. (This generally aligns with findings from the EPA, which has estimated that in 2011, there were more than 9,800 curbside recycling programs throughout the U.S., covering more than 70% of the population.)
Curbside collection is more common in larger cities and towns: 93% of the communities in the SPC study with populations greater than 125,000 provided single-family curbside recycling, as opposed to 65% of communities with populations below 50,000. (The Pew Research Center survey, interestingly, found a similar pattern but with lower rates: About seven-in-ten people living in urban and suburban communities said they had curbside recycling, compared with just four-in-ten rural residents, or 40%.)
Other researchers using different methodologies have come up with higher waste-generation estimates and lower recovery rates. For example, a new report from the Environmental Research & Education Foundation estimates U.S. municipal solid waste generation in 2013 at 347 million tons, with 27% of it being recycled or composted. Columbia University’s Earth Engineering Center, using a broader definition of municipal solid waste than the EPA, surveyed state and local waste management agencies and came up with an estimate of 389 million tons generated in 2011, with 29% recycled or composted.
Using data from the Columbia study, we calculated that California (53.4%), Maine (51.5%) and Washington state (50.1%) had the highest recovery rates for municipal solid waste in the nation in 2011; Oklahoma (3.7%), Alaska (4.5%) and Mississippi (4.8%) had the lowest.
But the perception that communities recycle “most types of items” obscures the markedly different rates at which various types of waste actually are recycled or composted. According to our analysis of the EPA data, 99% of lead-acid batteries (the sort found in cars and trucks), 88.5% of corrugated cardboard boxes, and 67% of newspapers, directories and the like were recycled as of 2013. On the other hand, only 28.2% of high-density polyethylene containers (such as milk jugs) were recycled, as were 13.5% of plastic bags and wraps and only 6.2% of small appliances. Three-fifths (60.2%) of yard trimmings were composted, but just 5% of food waste was.
About half (48%) of adults in the Pew Research Center survey say their community has services for recycling electronic devices, though about a third (34%) say they aren’t sure. People living in places that strongly encourage recycling in general are much more likely to say that electronics are recycled in their local areas most or some of the time, compared with people who live in communities that “do not really encourage” recycling (62% versus 15%).
Advocates say there are other important considerations in favor of recycling – prime among them that making products with recycled materials rather than virgin stock uses less energy and thus creates fewer greenhouse-gas emissions. The EPA estimates that the 87.2 million tons of materials recycled or composted in 2013 reduced greenhouse gas emissions by the equivalent of more than 186 million metric tons of carbon dioxide. However, critics point out that almost 80% of those greenhouse-gas benefits come from paper and paperboard recycling, and most of the remainer comes from recycling steel, aluminum and other metals.
