The study
Who took part
109 office workers at a telecom company in the Netherlands, all with admin jobs. The paper does not give their ages or sex.
What they did
Some groups wrote down, on a computer, when, where and how they would use central boxes for paper and cups. Another group got a personal paper box by their desk. Groups with no plan or box only had their bins checked.
What happened
Bins in the planning groups fell by roughly 75% for cups and 80% for paper, and the drop lasted two months. Groups with no plan or box stayed about the same. The paper box did as well as planning for paper, but did not change cups.
