Environmental impacts and greenhouse gas emissions assessment for energy recovery and material recycle of the wastewater treatment plant
Environmental impacts and greenhouse gas emissions assessment for energy recovery and material recycle of the wastewater treatment plant
- Science of the Total Environment, 784, p.147135, 2021 .
This study investigated the environmental burdens concerning the recycling/recovery process of a wastewater treatment plant's construction material waste and biogas. Detailed data inventories of case studies were employed in several scenarios to explore the role of end-of-life treatment methods. The ReCiPe 2016 and the Greenhouse gas Protocol life cycle impact methods were conducted to measure the impact categories. The construction and demolition phaseswere considered for recycling potential assessment,while the operational phase was examined for assessing the advantages of energy recovery. Metal and concrete recycling showenvironmental benefits. Increasing the reprocessing rate requiresmorewater consumption but results in: firstly, a decrease of 18.8
