The aim of the article is to analyze existing foreign experiences presented in the literature in the field of estimating demolition waste and their applicability in Poland condition. Using the case study method for more than a dozen objects, the authors prove the necessity to verify the suitability of the proposed models in relation to regional conditions (e.g. climatic conditions, local technologies, etc.). The amount of concrete waste from demolition of objects made in the analyzed technology is characterized by a low coefficient of variation, especially in the case of public facilities and is only 10%. However, in the case of residential buildings, the volatility was 16,7%. The calculated average index of concrete waste was compared with the two literature models. The results obtained differ from the values obtained from the models. Based on an analysis of the advantages and disadvantages of the selected models and their assumptions, a proposal has been formulated for the development of an effective tool for estimating demolition waste taking into account regional specific conditions together with the concept of sustainable construction. The focus was on waste from demolition of concrete objects.
