Construction industries are bulk generators of waste globally; improper management leads to environmental catastrophes. This paper identifies the significant factors through exploratory factor analysis and presents a novel approach to determining the causal relationships of various factors that lead to waste generation at construction sites by structural equation modelling. The analysis identifies maintaining and managing a site waste-management plan (SMP) as the top factor, with a path coefficient of 0·96. The impacts on waste generation of factors such as the operation stage (0·91), ordering and purchasing stage (0·84), hauling and handling stage (0·76), material handling stage (0·73), documentation (0·60) and culture (0·46) are quantified. Appropriate documentation provides the framework for SMP, on the basis of which other mitigation measures may be enforced, thus reinforcing the analysis results of SMP variables. Standardised documentation procedures for SMP need to be initiated and incentivised within existing green building performance rating frameworks, such as Green Rating for Integrated Habitat Assessment and Leadership in Energy and Environmental Design–India.

印度的建筑垃圾：识别原因的结构方程模型

建筑行业在全球范围内是大量的废物产生者。管理不当会导致环境灾难。本文通过探索性因素分析确定了重要因素，并提出了一种新颖的方法来通过结构方程模型确定导致建筑工地产生废物的各种因素之间的因果关系。该分析将维护和管理站点废物管理计划（SMP）列为首要因素，路径系数为0·96。操作阶段（0·91），订购和采购阶段（0·84），运输和处理阶段（0·76），物料处理阶段（0·73），文档编制（0）对废物产生的影响·60）和文化（0·46）被量化。适当的文档提供了SMP的框架，在此基础上可以实施其他缓解措施，从而加强SMP变量的分析结果。需要在现有的绿色建筑性能评级框架（例如，“综合栖息地评估和印度能源与环境设计领导地位”的绿色评级）框架内启动和激励SMP的标准化文件编制程序。
