RT info:eu-repo/semantics/article T1 Monetary valuation of unsorted waste: A shadow price approach A1 Sala Garrido, Ramón A1 Mocholi Arce, Manuel A1 Molinos Senante, María A1 Maziotis, Alexandros K1 Eco-efficiency K1 Ecoeficiencia K1 Circular economy K1 Economía circular K1 Waste management K1 Gestión de residuos AB Improving the management of municipal solid waste (MSW) is fundamental to promote circular economy and sustainability. Unsorted waste involves negative environmental impacts which often are ignored in economic feasibility studies due to its difficult valuation. In this study the shadow price of unsorted waste using the directional distance function was estimated. This methodological approach also allowed us to compute eco-efficiency scores of a set of municipalities in the provision of MSW services. The empirical application focused on a sample of 119 Chilean municipalities. The results showed that the average shadow price of unsorted waste was 297.66 €/ton which means that the environmental cost of left waste as unsorted was 297.66 € per ton. A regression tree model illustrated that population density, tourism intensity and the generation of waste per capita significantly influenced the shadow price of unsorted waste. Moreover, it was illustrated that Chilean municipalities were very inefficient in the management of MSW since the average eco-efficiency score was 0.272. The findings from this study reveal that additional and alternative policies should be adopted to improve the management of MSW and increase its recycling rate.
