ESTIMATION OF CONSTRUCTION AND DEMOLITION WASTE (C&DW) GENERATION USING DIFFERENT RATIOS OF WASTE PER UNIT AREA OF CONSTRUCTION
In this work, a model is presented for estimating the amounts of construction and demolition waste (C&DW) in Cantabria, a northern Spanish region. The European waste strategy, in the framework of the Sixth Environment Action Programme, considered C&DW to be one of the priority waste streams. Two different methodologies, classical and modern, can be applied for the estimation of C&DW. Classical methodology uses ratios based on population, while modern methodology combines municipal licenses and ratios of waste per unit area of construction, demolition and renovation. In this paper, modern methodology based on municipal licenses and four Spanish ratios from two Regional Associations of Architects, one Institute of Construction and a Regional Plan have been applied and their results were compared. Furthermore, several considerations have been taken into account to homogenize the data sources. The results show that most C&DW generated in Cantabria comes from new building construction, although demolition waste commonly presents the largest ratio of generation per unit area of demolition. On the other hand, the ratio from the Regional Plan shows the highest results. Comparing the calculated waste generation to disposal waste into municipal landfills has revealed a significant difference (around 40％), which could be due to the lack of laws on regulating proper management of C&DW in the past years. The presented methodology based on municipal licenses and four Spanish ratios for the estimation of C&DW can be used for giving useful information to make political and management decisions for this kind of waste in the region.
