Abstract Strategies for Municipal Solid Waste (MSW) management can be sustainable only because of site-specific analyses and choices that take into account not only financial but also environmental costs. Generally, a correct approach should use different scenarios based on the environmental, social, economic and technological conditions of the specific area and on its expected potential. The aim of this paper is to presents an innovative model for the implementation of integrated MSW management approach which can result extremely useful where the MSW systems have to be refined or even designed such in the case of low-income countries. The proposed approach provides the best solid waste (SW) allocation/distribution among the available treatments and disposal options minimizing at the same time the total cost by means of an optimization procedure. The environmental impacts of potential scenarios are simultaneously estimated by means of a tailored Life Cycle Assessment procedure. The LCA tool in the model focus on the specific impacts from a SW management scenario that makes the model more explicit with respect to traditional LCA application. Additional tools allow, through site-specific numerical models, to provide also a preliminary evaluation of local impacts when required (e.g. atmospheric emissions). Such a model can be useful as a supporting tool in decision making for both governmental and non-governmental institutions involved in the planning of more sustainable eco-friendly strategies for MSW management.

Statement of Novelty The paper presents an innovative holistic model that, based on optimization function, can allocate, in the framework of several scenarios, the optimal fluxes of solid waste to the different treatment/disposal (in operation or in programming) allowing to achieve, at the same time, environmental impact minimization and the optimum reduction of the overall costs. Waste fluxes are optimized on the basis of the minimum cost of the whole system management and a LCA procedure is applied to verify the environmental impact/costs either at local scale (if required) and at the global one. In this way the most sustainable solution can be implemented for a correct management of waste
