LIFE CYCLE ASSESSMENT OF A PASSIVE REMEDIATION SYSTEM FOR ACID MINE DRAINAGE: TOWARDS MORE SUSTAINABLE MINING ACTIVITY
Martinez, N.M., M.D. Basallote, A. Meyer, C.R. Canovas, F. Macias, and P. Schneider.
Journal of Cleaner Production 211:1100-1111(2019)
A life cycle assessment was performed for a dispersed alkaline substrate technology in the Iberian Pyrite Belt to determine the environmental impacts generated throughout its life cycle and the factors controlling its environmental performance. Results indicated that although the construction of the plant initially created significant environmental impacts, they became negligible within 4.5 years. Results also showed that the potential impacts of the plant were closely related to the upstream production chain of the materials employed in this technology. Thus, the replacement of certain material sources and circular usage would lead to a significant decrease in impact values. The replacement of wood chips by forestry waste would reduce emissions by 50%-100%. This study also found evidence for the lower carbon footprint of passive treatment in comparison with other wastewater treatment systems analyzed using life cycle analysis.
