Abstract

Institutions such as university communities can be considered miniature versions of the larger society in which they exist. Nonetheless even though it should be easier to manage waste at an institution, their waste management (WM) programmes are typically lack an overall goal for improving environmental impact and are not optimally structured or operated. In part this is due to a lack of a framework that promotes a goal-oriented WM strategy. For instance, zero waste (ZW) to landfill studies have gained prominence in recent years, but generally there is a lack of clear guidance on how to carry out ZW strategies effectively at either, municipal or institutional levels. To fill this gap, this study aims to provide a framework that enables institutions to develop a goal-oriented WM strategy applying the principles of material flow analysis and life cycle assessment. The framework assumes that no prior data are available, and a study will therefore begin by collecting primary data followed by secondary data. The case study is presented in this article, along with the introduction of the framework, using ZW management scenarios in the Istanbul Technical University Ayazağa Campus. The results of the case study show that, it is not possible to achieve ZW to landfill on university campuses. And simply diverting waste from landfill (min 74% to max ~100%) does not necessarily lead to circularity (min 20% to max ~66%) or directly address public attitudes towards ZW goals.

以目标为导向的废物管理研究的 MFA-LCA 框架:机构的 "零废物填埋 "战略。
大学社区等机构可被视为其所处大社会的缩影。然而,尽管机构内的废物管理应该更加容易,但其废物管理(WM)计划通常缺乏改善环境影响的总体目标,结构或运作也不尽人意。部分原因在于缺乏一个促进以目标为导向的废物管理战略的框架。例如,零废弃物填埋(ZW)研究近年来日益突出,但总体而言,对于如何在城市或机构层面有效实施零废弃物填埋战略缺乏明确的指导。为了填补这一空白,本研究旨在提供一个框架,使各机构能够应用物质流分析和生命周期评估的原则,制定以目标为导向的可再生资源战略。该框架假定之前没有可用数据,因此研究将首先收集原始数据,然后收集二手数据。本文在介绍该框架的同时,还介绍了伊斯坦布尔技术大学 Ayazağa 校区零排放管理情景的案例研究。案例研究结果表明,大学校园不可能实现垃圾零填埋。简单地将垃圾从填埋场转移(最小 74%,最大 ~100%)并不一定能实现循环(最小 20%,最大 ~66%),也不能直接解决公众对零废弃目标的态度问题。
