Intrinsic incentives in household waste recycling: The case of Italy in the year 1998

This paper studies the relationship between environmental concern and household separate waste collection, controlling for social capital, in Italy in the year 1998 when policy makers started to raise awareness of the importance of waste prevention, disposal and recycling. At the time, the public's sensitivity and attitude to waste issues were mainly influenced by their own lifestyles. We consider five separate waste collections, namely paper, plastic, glass, aluminium and food waste, to be taken to the relevant roadside containers. It focuses on three types of environmental concerns, classified as egoistic, altruistic and biospheric, and identifies five measures of general environmental issues able to match the different types of concerns considered. It also controls for three types of social relations: bonding, bridging and linking social capital. We use the dataset from the Multipurpose Household Survey, conducted by the Italian National Institute of Statistics (ISTAT), and five probit models to shape the number of separate waste collections. The results show that greater concern for waste production and disposal, pollution, climate change, resource depletion and alteration of environmental heritage is related to a higher likelihood of doing household waste recycling. Nonetheless, for the highest number of separate waste collections, the magnitude of the marginal effect of environmental concern variables decreases, showing the relevance of marginal costs in recycling behaviour. Finally, bridging social capital is the only social capital positively correlated with all five separate waste collections.
