摘要

埃塞俄比亚经济的快速增长和城市化导致了主要城市的广泛建设活动。众所周知,建筑活动会产生大量的废物,造成严重的环境问题。本文介绍了Mekelle市建筑垃圾管理实践的挑战,并探讨了以更可持续的方式解决问题的适当措施。通过实地观察、问卷调查和对各级公共部门官员的访谈,确定了城市建筑垃圾的来源和管理方案。调查结果显示,大部分受访者认为所属公司已采取不同措施处理建筑废物。调查显示,40%的受访者将非法倾倒作为处理废物的常用方法,其次是再利用和循环再造。很明显,超过75%的建筑产生的废物有潜力回收和再利用,作为道路和建筑物的回填和基础。香港的非法倾倒场地数目增加,显示当局未能妥善控制和实施有效的建筑废物管理。建议在地方一级可持续解决建筑废物管理取决于提高意识和促进建筑废物的再利用和回收。

Assessment of Construction Waste Management Practice in Mekelle, northern Ethiopia: Challenges and Opportunities
The rapid economic growth and urbanization in Ethiopia have led to extensive construction activities in major cities. Construction activities have known to generate large quantities of wastes that pose serious environmental problems. This paper presents the challenges of construction waste management practices in Mekelle city and explores appropriate measures to address the issues in a more sustainable way. Field observation, questionnaire survey, interviewing of public sector officials at different levels was conducted to identify the source and management options of construction waste in the city. The findings showed that the majority of survey participants felt that their firms have taken various measures to manage construction waste. It was revealed that 40% of the respondents exercise illegal dumping as a common method of waste management, which is closely followed by reuse and recycling. It is evident that over 75% of the construction- generated has potential for recycling and reuse as backfilling and base for roads and buildings. The increase in the number of illegal dumping sites in the city represents the failure to properly control and implement effective construction waste management. It was suggested that sustainable solution for construction waste management at local level depends on increasing awareness and promoting reusing and recycling of construction waste.
