Efficacité d’un feedback hebdomadaire sur la réduction du poids des ordures ménagères résiduelles

Abstract : Introduction. – Historically focused on waste sorting, waste management recently integrates its complemen-tary components: reuse and reduction. Objective. –“Pay as you throw” systems are presently fostered by the French prevailing legislation. In thiscontext, our research was designed to assess the relevance of a less coercive approach based on tailoredfeedback.Method. –Thirty-four households took part in the experiment and were divided into two conditions. Hou-seholds in the feedback condition received weekly information about their residual waste weight during14 weeks while those in the control condition received no information.Results. –Households in the feedback condition reduced their waste weight between the baseline period andthe experimental period significantly more than the control condition.Discussion. –Interviews of participants and literature review about the feedback approach enables us tosuggest improvements and relevant futures studies.
