Part B: Advances in gas emission control techniques for anaerobic-based STPs Technical Note 7 – Greenhouse gases emissions and compensations

Abstract

By making it possible to maintain terrestrial temperature at habitable levels, greenhouse gases (GHG) have reached levels of concentration never seen before. Although carbon dioxide (CO2 ) emissions from the decomposition of organic matter are considered neutral, sewage treatment by means of anaerobic process stands out for producing methane (CH4 ), an important GHG included in the carbon footprint concept. Thus, the proper management of gaseous emissions, whether through control and treatment, or through the use of biogas energy, consists of an important mechanism to mitigate, compensate or avoid GHG emissions. To make it easier to estimate the carbon footprint and the recovery energy potential, this technical note (TN) presents an electronic tool that includes the gaseous emissions control techniques addressed in this collection of TN. In view of these arguments, this TN aimed at discussing several topics of interest inherent to GHG and compensations under the context of anaerobic sewage treatment.
