In this paper, the Life Cycle Assessment (LCA) method was applied to investigate the environmental impact of the electrification of the urban bus fleet. Public bus transport in large urban agglomerations is one of the main sources of pollution. To reduce the generation of pollution, electrification of the bus fleet is considered as one of the potential solutions.

This is because of the fact that CO is more strongly adsorbed and also diffuses faster compared to methane in these materials. Therefore, the present study aimed to test alternative carbonaceous materials for the gas separation process with the purpose of enriching biogas in biomethane and to compare them with the commercial one.
