The article presents a case study concerning the improvement of the ‘kerbside’ waste collection system, now increasingly implemented in many Italian municipalities, as an alternative to traditional bring collection, with the aim of increasing the quality of waste collection and the collection rate, in order to reduce the final impact on the environment. A planning model for an integrated waste management system based on kerbside collection is presented. A heuristic procedure is also applied in order to obtain some admissible solutions of the real problem in reasonable computational time. The economic and environmental impacts are considered as significant elements for the evaluation and validation of the obtained solutions. Five alternative configurations of kerbside system, diverging in number of sub-area, synchrony of vehicles and directionality of the arcs, are compared in an economic point of view. Finally, Life-Cycle Assessment is used as a tool to compare the overall potential environmental impacts of the alternative of kerbside collection systems and also to compare the kerbside system with the traditional bring one. The different scenarios of kerbside system are comparable in terms of damage on the impact categories, while the bring system is the worst one, in terms of damage on human health, in the consumption of resources and also for the total damage score.

Abstract

The article presents a case study concerning the improvement of the ‘kerbside’ waste collection system, now increasingly implemented in many Italian municipalities, as an alternative to traditional bring collection, with the aim of increasing the quality of waste collection and the collection rate, in order to reduce the final impact on the environment. A planning model for an integrated waste management system based on kerbside collection is presented. A heuristic procedure is also applied in order to obtain some admissible solutions of the real problem in reasonable computational time. The economic and environmental impacts are considered as significant elements for the evaluation and validation of the obtained solutions. Five alternative configurations of kerbside system, diverging in number of sub-area, synchrony of vehicles and directionality of the arcs, are compared in an economic point of view. Finally, Life-Cycle Assessment is used as a tool to compare the overall potential environmental impacts of the alternative of kerbside collection systems and also to compare the kerbside system with the traditional bring one. The different scenarios of kerbside system are comparable in terms of damage on the impact categories, while the bring system is the worst one, in terms of damage on human health, in the consumption of resources and also for the total damage score.
