Plastic pollution is among the many socio-economic and environmental dilemmas that have engulfed Pakistan. The exponentially increasing consumption of plastic and the difficulty of dealing with its waste has compelled the government to impose a ban on the use of non-biodegradable plastics. This ban has made Pakistan the 128th country to curb plastic usage through punitive measures. However, the country lacks cheap and sustainable alternatives for plastic bags and bottles, which form the most significant chunk of plastic waste. This research study aims to analyze and propose alternatives that can replace these plastic bags and bottles without compromising the lifestyle of citizens. The aim of this study is two-fold; first, it employs Fuzzy VIKOR, a Multi-Criteria Decision-Making technique for comparison and prioritization of alternatives, i.e., Conventional Plastic bags, Paper bags, and Bioplastic bags, with respect to multiple aspects of sustainability. Secondly, it performs a cost–benefit analysis of a Bioplastic plant, with a focus on the production of biodegradable plastic bottles. The MCDM analysis prioritized the bioplastic bags, followed by paper bags and the least preferable alternative turned out to be conventional plastic bags. The cost–benefit analysis indicated that although the production of bioplastic bottles instead of conventional plastic bottles would lead to the reduction of detrimental environmental impacts, however, currently it is not financially profitable for the industrialists to switch to bioplastics. Therefore, it is recommended that government authorities should incorporate carbon taxes and subsidize the sustainable development sector, which would, in turn, lead to the reduction of plastic consumption and waste in society.

塑料污染是席卷巴基斯坦的众多社会经济和环境困境之一。塑料消费呈指数级增长以及处理其废物的困难迫使政府禁止使用不可生物降解的塑料。这项禁令使巴基斯坦成为第 128 个通过惩罚措施遏制塑料使用的国家。然而，该国缺乏廉价且可持续的塑料袋和塑料瓶替代品，塑料袋和塑料瓶是塑料垃圾中最重要的一部分。这项研究旨在分析和提出替代方案，以在不影响市民生活方式的情况下替代这些塑料袋和塑料瓶。本研究的目的有两个；首先，它采用模糊 VIKOR，这是一种多标准决策技术，用于比较和确定备选方案的优先级，即，传统塑料袋、纸袋和生物塑料袋，涉及可持续性的多个方面。其次，它对生物塑料工厂进行成本效益分析，重点是可生物降解塑料瓶的生产。MCDM 分析优先考虑生物塑料袋，其次是纸袋，结果证明最不受欢迎的替代品是传统塑料袋。成本效益分析表明，虽然生产生物塑料瓶代替传统塑料瓶会减少对环境的不利影响，但是，目前工业家转向生物塑料在经济上并不有利可图。因此，建议政府当局应纳入碳税并补贴可持续发展部门，这将反过来，
