The behaviour household as regards a municipal solid waste financed by payt system

The PAYT system (pay as you throw) for financing the municipal solid waste (MSW) is a new economic tool to improve the management of MSW in Europe and tested in France. The economic analysis was applied on a local authority where the tariff is based on the number of wheeled bin emptying. We observe a decrease over 40% of the amount of residual waste, an increase of packaging collected and a development of prevention (temporal analysis). The meaning is a new behaviour of citizens regarding their waste to reach a lower payment. To explain, we intend to present the data analysis of a sample survey of the population and the results of an econometric model to evaluate the reaction of households in relation with the level of fees. We have distinguished three types of explanatory variables : sociological, economical as income households and technical linked with the frequency of collection, composting garden, civic amenity. Illegal diversions, as compaction waste in bin or burning in garden or illegal dumping, are not a reason to renounce the PAYT system. More than 90% of surveyed population approve the system.
