Would you recycle more if every bottle gave you a chance to win $1,000?
If you live in one of the 10 U.S. states with a bottle deposit program, you’re probably familiar with the idea of feeding your empty plastic bottles or aluminum cans into a machine and getting a few cents back for your effort. But what if instead of earning a nickel or a dime, you could be entered in a lottery for a chance to win a bigger prize with each bottle you return? That option actually motivates people to recycle more bottles, researchers discovered when they tested it out on a small scale. Not only did people recycle more often, but they actually felt a little happier after doing so (compared with when getting a regular 10-cent return). And, it turns out, Norway already offers this incentive and also has one of the highest rates of recycling for plastic bottles in the world, at about 97%. This idea that people prefer a small chance at a bigger prize to a small reward is a common one in behavioral economics, says Jiaying Zhao, a professor of psychology and sustainability at the University of British Columbia and one of the authors of this study, which was recently published in the journal Waste Management . She wanted to see if the same principal could help spur sustainable behavior changes. Bottle deposits already help increase recycling rates . In the U.S., beverage containers (including plastic and glass bottles and aluminum cans) that are eligible for a bottle deposit have an average recycling rate of

In many parts of the world, recycling programs rely on small financial incentives to motivate people to return used plastic bottles and aluminum cans. In the United States, bottle deposit programs offer a few cents per container, encouraging consumers to participate. However, a recent study suggests that the prospect of winning a larger prize could be even more effective in driving recycling rates. Researchers found that people are more likely to recycle bottles if they have a chance to win a significant amount of money, such as $1,000, with each return. This approach not only increases recycling frequency but also enhances the emotional satisfaction of participants.
The study, conducted by researchers at the University of British Columbia and published in the journal Waste Management, tested this hypothesis on a small scale. Participants were given the option of receiving a regular 10-cent refund for their bottles or entering a lottery with a 0.01% chance of winning $1,000. The results showed that people were more inclined to recycle when they had the possibility of winning a larger prize. Moreover, those who opted for the lottery reported feeling happier after recycling compared to those who received the standard refund.
This finding aligns with principles from behavioral economics, which posits that people often prefer a small chance at a significant reward over a certain smaller reward. Jiaying Zhao, a professor of psychology and sustainability at the University of British Columbia and one of the study's authors, was interested in exploring whether this principle could be applied to encourage sustainable behavior changes.
Interestingly, Norway has already implemented a similar incentive, offering a chance to win money for every bottle returned. As a result, the country boasts one of the highest recycling rates for plastic bottles globally, at around 97%. This success story highlights the potential of combining financial incentives with the allure of a potential big win to drive recycling.
Bottle deposit programs in the United States have proven effective in increasing recycling rates. Containers eligible for a deposit, such as plastic and glass bottles and aluminum cans, have an average recycling rate of 64%. In contrast, beverage containers not eligible for a refund have a much lower recycling rate of just 24%. This disparity underscores the importance of deposit laws in promoting recycling. However, the study suggests that offering a chance at a larger prize could further boost recycling rates, particularly in states without deposit programs or for containers exempt from such laws.
The researchers set up bottle return locations in British Columbia and Alberta, Canada, to test their hypothesis. Participants could choose between the standard 10-cent refund or the opportunity to win $1,000. The results confirmed that the prospect of a significant prize motivated more recycling and enhanced participant satisfaction.
This innovative approach to recycling incentives could have a profound impact on waste management and environmental sustainability. By leveraging the human tendency to seek out potential rewards, policymakers and businesses can design more effective recycling programs. The study's findings not only provide valuable insights into behavioral economics but also offer a practical solution to the global challenge of reducing plastic waste.
In conclusion, the idea of entering a lottery for a chance to win a substantial amount of money with each bottle return appears to be a powerful motivator for recycling. This approach not only increases recycling rates but also enhances the emotional experience of participants. As more regions and countries explore innovative ways to promote sustainable behavior, the success of Norway's model serves as a compelling example of how financial incentives combined with the allure of a potential big win can drive significant environmental benefits.
