Abstarct: Abstract Today, among the synthetic materials whose production is increasing day by day in different types and applications, is plastic and plastic compounds. These plastics have been used in the production of various industrial products, and these materials have created complex environmental challenges as waste resistant to microbial decomposition. To solve this challenge, researchers are looking for the production of biodegradable plastics (they are easily decomposed by living organisms or their microstructures and do not remain in the environment). The main goal of the current research is to identify and evaluate the barriers to the production of biodegradable disposable containers with the help of multi-criteria decision making techniques in the environment of z numbers. According to the nature of the problem, the current research is a descxriptive-analytical research. The statistical population of the research includes the specialists and experts in the production of disposable biodegradable containers in the factories (Be Zeit Tehran, Zeit Behod Pars, Zarin Shimi, MG Plast, Kimia Samane Sabz, Navad Tabriz, Pars Plastic Khuzestan, Shiraz Sabz, Mehr Parsa, Adina plastic). Sampling of experts was done until reaching theoretical saturation, and the sample size of 10 tons of factory experts was selected; The method of collecting information was library and field (questionnaire tool). Descxriptive statistics (mean) and multi-criteria decision-making techniques have been used for data analysis in the environment of z numbers. The findings from the data analysis show that among the economic challenges; The challenge of the cost of raw materials for the production of degradable plastics of the highest rank; Among the technological challenges, the challenge of not having access to global markets to update new production technologies is in the first place, and among the legal challenges, the challenge of not implementing the production of biodegradable containers with the rules and regulations governing environmental policies are in the first place. The results of the current research show that the most challenges are related to the financial dimension, then the economic dimension, and finally the legal dimension.
