Abstract: While constructed wetlands have proved to be successful in the treatment of various wastewaters, their ability to co-treat wastewaters with different characteristics has not been thoroughly examined. To this end, four pilot-scale horizontal subsurface flow constructed wetlands were used to co-treat secondary cheese whey and hexavalent chromium. Based on the experimental results constructed wetlands proved to be effective in co-treating these two wastewaters as they achieved 100% removal of hexavalent chromium, while mean COD removal ranged between ranged between 50% and 70%.

Abstract: The transport sector is responsible for a significant portion of global emissions of carbon dioxide - CO2. The measurement of such emissions, when held in grams of CO2 per passenger-kilometer, enables more significant results, considering the passenger load. This work aims to analyze CO2 emissions per passenger-kilometer from subway systems, comparing those results with buses and private cars, establishing a methodology for calculating these emissions. The methodology was applied to Rio de Janeiro Subway in Brazil.
