Minimizing the Costs of Waste Prevention through Behavior Change
Monday, September 25, 2017

The generation of household waste has become a global concern in recent years. Waste prevention policies have been acknowledged as one of the most beneficial environmentally and cost-effective option to decrease municipal solid waste. However they still have not shown any perceptible effect on reducing urban waste. While it is true that waste prevention is universally accepted, it can only be successful when accompanied by changes in human behavior. Several intervention strategies for behavior change have been developed, tested and evaluated. However, they usually have difficulties in achieving enduring change. This study introduces a new approach to design intervention policies by using a target behavior model aligned to situational factors. This allows minimizing the costs required to implement waste prevention. An important feature of this study is the combination of social psychological measures with environmental and economic actions, making possible to observe relations between aspects of motivations and outcomes on waste reduction. In general, results show that participants improved their involvement in most activities. This research may provide the much-needed justification to municipal authorities in developed and developing cities to apply fully waste prevention as their most important input in waste management.
By attending this presentation, participants will have the opportunity to discuss different implications of individuals’ behavior not only on waste prevention strategies but also on consumption and recycling.
