Abstract

The environmental and construction legislations are not modernized to control the adverse impacts of construction activities in Bangladesh. A large volume of Construction and Demolition (C&D) waste and carbon are annually released from this sector. This research was undertaken to investigate the Green Supply Chain Management (GSCM) practices and its implications during the implementation in constructions. Three construction industries and three related material manufacturers were selected for case study, and thirty industries combing both categories were investigated through questionnaire survey to unravel current GSCM practices, and its challenges and effect on constructions. Results revealed that market (76.67%) and supplier (91.03%) pressures promoted GSCM practices in construction industries, additionally internal factors played significant role (74.44%), whereas 60% regulations as external pressure. As GSCM elements, green manufacturing (90.83%), green purchasing (85.83%), internal environmental management (82.5%), investment recovery (86.66), and eco-design (93.33%) respondents agreed to improve the construction industry to reduce C&D waste and carbon emission. About 89% and 79% respondents acknowledged the environmental and economic performances, respectively improved by GSCM practices. Furthermore, 70–90% respondents opined financial/technical/human application as key barriers in GSCM practices. Finally, the GSCM practices reduced C&D waste and carbon emissions; however, it was not maintained regularly and strictly.

绿色供应链管理实践对减少孟加拉国建筑垃圾和碳排放的影响

孟加拉国的环境和建筑立法尚未现代化，无法控制建筑活动的不利影响。该行业每年都会产生大量的建筑和拆除（C&D）废物和碳排放。本研究旨在调查绿色供应链管理（GSCM）实践及其在建筑业实施过程中的影响。本研究选取了三个建筑行业和三个相关材料制造商作为案例研究对象，通过问卷调查的方式对这两个行业的三十个行业进行了调查，以了解当前的绿色供应链管理实践及其挑战和对建筑业的影响。结果显示，市场压力（76.67%）和供应商压力（91.03%）促进了建筑行业的 GSCM 实践，此外，内部因素也发挥了重要作用（74.44%），而 60% 的法规则是外部压力。作为 GSCM 的要素，绿色制造（90.83%）、绿色采购（85.83%）、内部环境管理（82.5%）、投资回收（86.66）和生态设计（93.33%）受访者同意改善建筑行业以减少建筑废弃物和碳排放。分别有 89% 和 79% 的受访者认为，通过实施《建筑业质量管理规范》，环境和经济效益均有所改善。此外，70-90% 的受访者认为资金/技术/人力应用是 GSCM 实践的主要障碍。最后，GSCM 实践减少了 C&D 废物和碳排放，但没有得到定期和严格的维护。

期刊介绍： The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
