Abstract:
Behavioural determinants of waste recycling and reduction activities of households have received a growing research attention in several
disciplines and from different perspectives, ranging from economics, environmental psychology, sociology and engineering. We put ourselves in this
stream of literature by analyzing both theoretically and empirically the interrelations among personal motivations, knowledge of environmental
problems and policy in determining waste related behaviours. Under a theoretical point of view, we explicitly model the role played by personal
values and knowledge in affecting waste recycling and reduction decisions. We explicitly consider the multidimensional nature of intrinsic
motivations, allowing for complementarity or substitutability among efforts towards recycling and waste reduction in the utility function. As a
result, we show that knowledge, policies and green attitudes affect recycling (waste reducing) behaviours directly, but also indirectly, through their
effect on waste reduction (recycling).
Theoretical predictions are then tested in a structural equation model, by using data from the Survey of Public Attitudes and Behaviours toward
the Environment (Defra, 2010), which is representative of the population in England in 2009. As in the theoretical part, our empirical investigation
of the predictors for waste management behaviours distinguishes between recycling and minimization activities, but it goes further by specifying
the role played by situational variables, personal beliefs, social norms and free-riding incentives in determining individual waste-related intentions
and actions. We also show that environmental knowledge
