Recycling construction materials in a developing country: four case studies
This study identifies, documents, and assesses the existing levels of awareness and implementation of sustainability practices amongst the different participants in the Lebanese construction industry. The analysis is based on a survey of owners, designers, and contractors supplemented with four case studies illustrating the recycling of construction demolition waste (CDW). The results indicate an acceptable level of awareness, but a mediocre level of implementation of sustainable practices which were limited to green design efforts and uncoordinated attempts at recycling construction demolition materials. The study concludes with recommendations on how to: 1) further improve awareness regarding sustainable practices amongst the various stakeholders in the Lebanese construction industry; 2) overcome some of the obstacles preventing higher recycling rates.
