摘要

在斯里兰卡,建筑和拆除废物的管理是一个主要问题,导致环境退化和资源枯竭。本研究旨在通过考察斯里兰卡建筑业实施循环经济战略的情况来解决这些问题。重点是在拆除和重新利用期间,以及建筑项目生命周期的材料回收和生产阶段,减少废物产生,最大限度地提高资源利用率。这些阶段在废物产生和资源消耗方面至关重要。本研究采用定性方法,利用德尔菲技术通过一系列三轮专家访谈收集见解。在第一轮比赛中,有17名专家参与,第二轮比赛有15名专家,最后一轮有12名专家。使用人工内容分析方法对从这些访谈中收集的数据进行了分析。根据研究结果,在斯里兰卡的拆除和重新利用阶段,共发现了14个C&D废物管理(WM)问题。针对每一个问题,都提出了有效克服这些问题的适当战略。此外,该研究考察了在项目管理铁三角的背景下,CE策略对最大限度地减少这些问题的影响。同样,该建筑的材料回收和生产阶段提出了八个C&D WM问题,每个问题都附有相应的解决策略。考虑到项目管理的铁三角关系,本研究还探讨了CE策略在缓解这些问题方面的影响。在拆除和重新利用阶段,CE战略侧重于减少废物产生和优化资源利用。这包括仔细解构建筑,以抢救和回收可重复使用或重新利用的材料。

Circular economy strategies for waste management in Sri Lanka: A focus on demolitions and repurpose and material recovery and production stages.

In Sri Lanka, the management of Construction & Demolition (C&D) waste poses a major problem, leading to environmental degradation and depletion of resources. This study aims to tackle these issues by examining the implementation of Circular Economy (CE) strategies within the construction industry of Sri Lanka. The focus is on reducing waste generation and maximizing resource utilization during the demolitions and repurpose, as well as material recovery and production stages of the building project life cycle. These stages are crucial in terms of waste generation and resource consumption. A qualitative approach was employed in this research, utilizing the Delphi technique to gather insights through a series of three rounds of expert interviews. In the first round, 17 experts were involved, followed by 15 in the second round, and 12 in the final round. The data collected from these interviews were analysed using manual content analysis methods. Based on the research findings, a total of 14 C&D Waste Management (WM) issues were identified specifically in the Demolitions and Repurpose Stage in Sri Lanka. For each issue, suitable strategies were proposed to overcome them effectively. Furthermore, the study examined the impact of CE strategies on minimizing these issues within the context of the project management iron triangle. Similarly, the Material Recovery and Production Stage of the building presented eight C&D WM issues, each accompanied by corresponding strategies to address them. The research also explored the influence of CE strategies in mitigating these issues, considering the project management iron triangle. During the demolitions and repurpose stage, CE strategies focus on reducing waste generation and optimizing resource utilization. This involves carefully deconstructing buildings to salvage and recover materials that can be reused or repurposed.
