Household curbside recycling behavior was observed in two similar, adjacent cities. In one, all recyclables were mixed together, and in the other, four types of materials were separated. As predicted, the commingled program achieved a higher average weekly participation rate (58% vs. 42%), and more households participated at least once in 8 consecutive weeks (90%o vs. 77%/6).
