Question

List three major factors influencing the amount of ghg emissions

Answer 1

Global energy intensity measured has the amount of primary energy demand needed to produce 1 unit of gross domestic product gpd fell by 1.8% in 2016 this improvement in energy intensity is the main reason why Global energy related every green gas emission have lived off since 2040 low energy intensity was responsible for of setting three quarters of the increase in emission due to the gpd grow them with the ship to renewables and other no emissions use of setting The Other quarter

Answer 2

Answer:

The operation of wastewater treatment plants results in direct emissions, from the biological processes, of greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as indirect emissions resulting from energy generation. In this study, three possible ways to reduce these emissions are discussed and analyzed:  minimization through the change of operational conditions,  treatment of the gaseous streams, and  prevention by applying new configurations and processes to remove both organic matter and pollutants. In current WWTPs, to modify the operational conditions of existing units reveals itself as possibly the most economical way to decrease N2O and CO2 emissions without deterioration of effluent quality. Nowadays the treatment of the gaseous streams containing the GHG seems to be a not suitable option due to the high capital costs of systems involved to capture and clean them. The change of WWTP configuration by using microalgae or partial nitritation-Anammox processes to remove ammonia from wastewater, instead of conventional nitrification-denitrification processes, can significantly reduce the GHG emissions and the energy consumed. However, the area required in the case of microalgae systems and the current lack of information about stability of partial nitritation-Anammox processes operating in the main stream of the WWTP are factors to be considered.
