In this article, the authors, O’Connor, Lerman, Fritz, & Hodde, are expanding on current research concerning increasing the recycling habits of U.S consumers.

The researchers then summarizes previous studies done to assess pro-recycling interventions. These interventions include methods such as: increasing the number of recycling bins in a given area, posting recycling fliers, and changing the location of current recycling bins.

specify that some of the previous research does not control for certain confounding variables. In their study, the authors hope to reduce extraneous variability by “…controlling the number of recycling receptacles across conditions and by examining receptacle location without the use of posted signs” (712). The specific recyclable waste being measured was plastic water bottles. The location of the study was a university in southeast Texas and the population examined were those who attended the
