Werner et al. (1995):



In 1995, a study was conducted by Werner et. al.(1995) to observe techniques that may increase participation in a curbside recycling program, as well as helping to understand long term behavior and attitude change towards recycling.

 

​

Results:



• Written commitments were more likely to get members to participate than face-to-face communication, telephone calls, or flyers.



• Commitment and behavior could work to change attitudes towards recycling.
