Deposit schemes reduce drink containers in the ocean by 40% – AustraliaPosted on August 1, 2018 by DrRossH in Plastic Limiting Regulations
Drink containers end up in the ocean at a truly alarming rate. Simply paying people a small amount to return them cuts that rate by nearly half.
We were also interested in whether other factors also influenced the amount of containers in the environment. We tested whether the socio-economic status of the area (as defined by data from the Australian census) was related to more containers in the environment. Generally, we found fewer containers in the environment in wealthier communities. However, the presence of a container deposit reduced the container load more in poorer communities.
This is possibly because a relatively small reward of 10 cents per bottle may make a bigger difference to less affluent people than to more wealthy consumers. This pattern is very positive, as it means that cashback programs have a stronger impact in areas of lower economic advantage, which are also the places with the biggest litter problems.
