MATERIAL WASTE MANAGEMENT IN THE TURKISH CONSTRUCTION INDUSTRY: THE CASE STUDIES OF PREFABRICATED AND MODULAR BUILDINGS

Abstract

Construction wastes have been known to generate large and diverse quantities of waste with 37.5%. Material wastes, one of the physical wastes, have a strong impact on the waste generation. The magnitude of material waste in the construction industry also reveals the need to manage material waste. Effective material waste management, starting by preventing waste from occurring, will not only reduce costs but also contribute to environmental sustainability. Therefore, selecting appropriate construction methods and materials before starting a project is important for material waste management. Prefabricated and modular systems, thanks to their production and implementation methods, reduce material losses in the construction industry and significantly reduce waste, especially in the construction process. In this study, two different completed projects, one modular and one prefabricated, are analyzed. These projects are evaluated and compared in terms of material waste during the construction process. It is thought that the findings of this study will contribute to the effectiveness of prefabricated and modular construction perception for the construction industry in terms of material waste generation.
