Methodology for estimating biowaste generation using municipal rurality indexes


 The separate collection and management of biowaste (BW) must be implemented in next years in the European countries. In order to define a properly BW strategy, it is necessary to estimate the generation at a municipal level, since depending on the amount to be treated, the strategy may notably vary. The aim of this study is to develop a methodology to estimate the BW generation at municipal level, taking into account the characteristics of the region, the Municipal Solid Waste (MSW) management applied, and different socio-economic variables that define the level of rurality of a municipality. A model to estimate the BW generation for each type of municipality has been developed using Multiple Linear Regression Analysis. As input data has been used, on the one hand, results from a Waste Compositional Analysis used for estimating the BW fraction of the mixed waste collected; and on the other hand, data of socioeconomic variables that have demonstrated to influence the generation of waste. Significant influence of socioeconomic variables on the level of BW generated is observed for the rural municipalities.
