1649 manufacture of products and are discarded after end of use as waste. The model is also called the end-of-thepipe. We must first replace this model with the Urban Mining model in which it is also includes the re-use of end-of-life products, buildings/facilities and waste, which stand out from the end-of-pipe model and upgrade it by their integration into the circular model. The Urban Mining model, makes it easier to leave the old linear model, so-called. model of "dredging in waste", but before entering into the Circular model, it is necessary to develop a systemic approach and to follow the principles of Industrial Ecology in the implementation of various activities for the extraction and reuse of waste/secondary materials. The goals followed by the Urban Mining model relate primarily to the extraction of the secondary raw materials, energy recovery, remediation of environmental burdens and damages, rehabilitation and reuse of land with deposited wastes for other purposes, reduction of maintenance costs and costs of institutional control of closed landfills as well as the implementation of mining works in an urban areas with less impact on the environment. 2. URBAN MINING MODEL The definition of the Urban Mining model, mainly due to different interpretations, is not yet final. Some understand a model to describe the recycling of resources from old landfills, others use it to explain traditional waste recycling schemes, such as, for example, construction waste, scrap iron, waste plastic or glass, and thirdly, it is understood as the development of more environmentally friendly mining methods and techniques for the exploitation of mineral resources in the vicinity of urban areas. Urban Mining model denotes a new systematic approach to the re-use of anthropogenic substances from urban environments and is based primarily on the fact that, in addition to geological environments, large quantities of different materials are located in urban areas, not only in buildings and infrastructure, but mainly in used products and wastes in landfills. These deposited secondary materials represent a large potential source, which after the end of their life or after cessation of their use, are mainly the possibility of re-use. The Urban Mining model is essentially a new approach towards the implementation of material and energy recycling. Figure 1 - Principle of Urban Mining model [9,10]. Before implement of the Urban Mining model, the principle you can see in Figure 1., we must first obtain foremost reliable and credible data on material mass flows and waste quantities. Similar to the exploitation of primary (non-renewable) mineral resources, we must know the waste characteristics, such as
