ABSTRACT
The construction industry presents the third largest polluter of the environment. One of the significant aspects of environmental pollution is an origin of construction and
demolition waste (C&DW) which present even ⅓ of total waste generation in the
European Union. Given that, the European Union legislation and its subsequent
implementation into the national laws is detailed focused on waste management. The
relevant laws and regulations exactly define the obligations of construction waste
producers (i.e. constructors or construction companies) in the field of C&DW disposal.
One of the integral parts of this procedure is a detailed registry of wastes type and
amount. On the other hand, currently in Slovakia is not any methodology that allows
accurately and clearly determine of origin C&DW quantity and its identification
according the European waste list already during the realization or reconstruction of
buildings. Subsequently, the record system of C&DW is weakly controllable, thus are
creating the area for the reporting of inaccurate (often skewed) data concerning the
waste origin. The submitted paper is focused on the analyses of foreign studies and ICT tools used in the field of C&DW quantification and classification on building sites and the mapping of the facts in the registration C&DW origin in the conditions of Slovak construction. Based on the obtained knowledge and the analysis of legislative requirements in field of waste management is proposal the system for determining of type and amount C&DW from particular construction processes. The key element of presented methodology is the processing of C&DW matrix, which is aimed at identifying the construction processes and type and amount of C&DW during its realization. The proposed matrix of C&DW can present the simple tool for the classification and quantification of C&DW on building site, which clarifies the data in field of C&DW registration. The matrix functionality was verified in several case studies.
