Solid Waste Treatment

The aim of this study was to assess the economic and environmental advantages of implementing reverse logistics to recycle solid waste from construction companies. The adopted research method was based on a systematic literature review and two case studies. For the economic assessment, the return on investment, the internal rate of return, and the discounted payback factors were considered, while the material intensity factor was used for the environmental impact assessment. This study shows that there are economic and environmental advantages associated with the use of reverse logistics for solid waste treatment and recycling. In 2016, the purchase of recycled blocks resulted in a profit of over US$45,000 for one company, and another company earned almost US$250,000 in the same year by recycling solid waste from manufacturing blocks and selling iron, wood, paper, and plastics. Furthermore, the environmental impact was reduced. This paper contributes to the dissemination of knowledge regarding the advantages of adopting reverse logistics for recycling construction and demolition waste, and creates new opportunities for companies.
