  7. Abstract:
  8. Construction is a vast industry. It is one of the vital and important industries in each country because of high financial turn over, creating many job opportunities and developments. Development has always been a great challenge to the environment due to using much of natural materials and resources. Studies show that construction projects produce the highest amount of waste among other industries. By continuing current situation and increasing rate of production of construction waste, nations and human beings will face a lot of problems in the future. Recently, an increasing attention has been focused worldwide to limit using natural resources in order to conserve the environment.
    Construction waste management has become more essential and of great concern considering significantly the large amounts of construction waste production and increasing importance of environment. Nowadays, improving activities is one of the construction industry’s concerns in order to mitigate environmental impacts. Reducing construction waste will directly reduce adverse environmental impact. Appropriate policies need to be implemented in order to reduce and manage construction waste on the whole life cycle of a project. Setting policies in this area needs making appropriate and essential decisions. Thus in this research, we aim to identify more important factors in construction waste management and minimization on the whole life cycle of project by doing field study and introduce them to decision and policy makers in the construction industry. A hybrid research methodology is applied to identify significant factors in construction waste management and minimization, then final factors are ranked by liker scale. According to the research findings, the most important factors of construction waste minimization are: applying low waste technologies, training, selecting low quality materials, implementation waste minimization supervision, inadequate work experiences of constructing agents, use of standard dimensions and units (modular design) and etc. By applying waste minimization policies and also reusing of materials, much amount of natural resources will be saved due to decreasing material usage and this help to improvement of built environment. In this regard, a framework is offered to building constructions with the approach of reducing waste on the whole life cycle of project. At last, the new concept of virtual design, construction and deconstruction (VDCD) is presented to minimize and manage waste better.
