Managing construction and demolition (C&D) wastes has challenged many municipalities with diminishing waste disposal capacity. Facing such challenges, the Massachusetts Department of Environmental Protection proposed a policy restricting the landfill disposal of certain C&D waste materials, if unprocessed. This research is to study the potential economic impact of such restriction on construction contractors and C&D waste processors. A spreadsheet-based systems analysis model has been developed to assist the cost-benefit evaluation for various C&D waste management scenarios. The model, developed based on the mass balance principle, is designed to track a C&D waste stream through the various stages of a waste management system, i.e. generation, source separation, processing, recycling, and final disposal. This model, by incorporating the material flow data with the cost/revenue data associated with each management activity, can then provide an economic analysis for a proposed C&D waste management scenario. A case study illustrating the application of this model for Massachusetts is also presented.
管理建筑与拆除（C&D）废物给许多垃圾处理能力不断下降的市政当局带来了挑战。面对这些挑战，马萨诸塞州环境保护部提出了一项政策，限制某些未经处理的C&D废料的填埋处理。本研究旨在探讨这种限制对建筑承包商和C&D废料处理商的潜在经济影响。已开发出一个基于电子表格的系统分析模型，以协助对各种C&D废物管理方案进行成本效益评估。该模型基于质量平衡原理开发，旨在跟踪C&D废物流经废物管理系统的各个阶段，即产生、源头分离、处理、回收和最终处置。通过将物料流数据与每个管理活动相关的成本/收入数据相结合，该模型可以为提议的C&D废物管理方案提供经济分析。还给出了一个说明该模型在马萨诸塞州应用的案例研究。
