One of the challenging issues of any country's agenda today is the management of solid waste in the circular economy and eco-efficiency perspective. In this context, there has been much debate about the disposal of diapers, but the current research lacks data for developing countries. Furthermore, the research lacks quantification of data, in terms of output products generated through sustainable waste management practices particularly for diapers. Thus, this research aims to develop a quantitative study based on Life Cycle Assessment (LCA) and Life Cycle Costing Analysis (LCCA) which help to evaluate the overall eco-efficiency of various disposal methods by taking into account their net input and resultant monetary value, in the context of Pakistan. To cover limitations of LCA approach, results have been compared along with the expert's opinion using the well-known multi-criteria method Fuzzy logic and Technique for Order of preference by similarity to ideal solution (TOPSIS) technique. Human health and environment have been used as end-point indicators. The main research result points out that incorporating small scale incineration plants along with recycling using Thermal Pyrolysis Hydrolysis (TPH) plants can help to sustainably dispose-off diapers. The results also indicate the importance for policy makers and industrial sector to find solutions to facilitate implementation of circular economy principles for diapers. In fact, the recycling of diapers using waste-to-energy technologies is a significantly eco-efficient alternative for the Pakistani market, which can be pivotal for Sustainable development and initiation of a circular economy model.
当今任何国家议程上的一个挑战问题是在循环经济和生态效率的角度管理固体废物。在这种情况下,关于尿布的处理已经有了很多争论,但目前的研究缺乏发展中国家的数据。此外,研究缺乏数据的量化,就通过可持续废物管理实践产生的输出产品而言,特别是对于尿布。因此,本研究旨在基于生命周期评估(LCA)和生命周期成本分析(LCCA)进行定量研究,通过考虑其净投入和由此产生的货币价值,来评估各种处理方法的整体生态效率,特别是在巴基斯坦。为了弥补 LCA 方法的局限性,使用众所周知的多标准方法模糊逻辑和与理想解相似的偏好顺序技术(TOPSIS 技术),将结果与专家意见进行了比较。人类健康和环境被用作终点指标。主要研究结果指出,将小型焚烧厂与使用热解水解(TPH)工厂的回收相结合,可以帮助可持续地处理尿布。结果还表明,决策者和工业部门必须找到解决方案,为在巴基斯坦实施循环经济原则提供便利。事实上,利用废物转化能源技术对巴基斯坦市场进行尿布回收是一种非常生态有效的替代方案,这对于可持续发展和启动循环经济模式至关重要。
