today, with rapid advancement of industry and technology, many concerns about the adverse consequences threaten human life. The objective of this research is to investigate environmental education as an implement to reduce and evaluate the environmental consequences of petrochemical products based on the hierarchical analysis. The methodology was a survey of a statistical group involving 30 managers and experts in the petrochemical industry. The tool for the survey has consisted of a questionnaire with a pair scale-single response. In this model, the validity of the research was confirmed by the Delphi method and obtaining the opinion of experts in the field of occupational health and reliability of the questionnaire calculated by the inconsistency rate (less than 0.1). First, three criteria including environmental impact, destruction of the natural environment, impacts on individual health, and the most important harmful effects of each criterion were identified. Among the three main criteria, the most influential factor is the environmental impact criterion with a relative weight of 0.670. The criteria for the destruction of the natural environment and health effect of petrochemical workers with a relative weight of 0.260 and 0.699, respectively, are in the next priority. The water pollution parameter with a relative weight of 0.602 is the most important among the 5 sub-criteria. The parameter of effects on the biological environment with a relative weight of 0.373 among the 3 sub-criteria, and the parameter of the respiratory system with a relative weight of 0.417 among the 5 sub-criteria have the greatest effect, respectively

Consumerism is a new phenomenon created in the 21st century that can play a substantial role in the destruction of national resources of any country. Nowadays, concerning the ever-increasing improvement of fashion in the world, consumerism in the field of textiles and clothing is raised more than ever. Considering the wasteful consumption of products may bring about remarkable damages to the environment, presently certain methods such as no waste clothes production with a sustainability approach are under attention and survey. Researches accomplished in this regard resulted in the initiation of methods that are used by designers around the world as leading methods. Since this approach is an unprecedented opinion that is still in the route of extension and expansion, just a few studies have been conducted regarding the results obtained so far from designing zero-waste clothes and the experiences of consumers' awareness of this approach. The present research, regarding its objective, is of applied type based on descriptive-analytical method and procedure. Data collection is achieved by library method, relying on documents, written sources, and the internet. It challenges the discovery of the roots in this being formed field using the point of view proposed by Keith Fletcher. By explaining the experiences of this researcher in holding workshops related to this opinion, the out comings are surveyed. The obtained results confirm the application of various techniques such as digital printing patterns and the use of updated universal technology for the elimination of wastes.
