Reducing municipal waste remains a major policy challenge in France, in line with the European Union’s Circular Economy Action Plan. Unit-based pricing (UBP) is a key instrument to reduce waste generation and improve sorting, yet its public acceptability is debated. This paper analyzes households’ preferences for UBP schemes and the role of non-monetary behavioral incentives in shaping that acceptability. Using a discrete choice experiment on a representative sample of 3,000 French households, we vary UBP modalities and core characteristics of the waste management system. A randomized split-sample design compares a nudge, a boost, and a control group. Preferences are estimated with an error-component mixed logit model and a latent class analysis. The results reveal substantial heterogeneity: environmentally motivated households and those previously exposed to UBP are more likely to accept weight-based and drop-off schemes, particularly when nudged. While the nudge is effective in reducing the overall rejection of UBP in the sample, the boost shows a significant effect only among pro-environmental individuals, highlighting the importance of motivation for the effectiveness of this tool. Overall, these findings underscore the interaction of two key dimensions in increasing UBP acceptability: the compatibility of the waste management system with households’ recycling practices, particularly the type of UBP, and carefully designed behavioral interventions.
