Abstract:
In the current global context, attention is being paid towards the sustainability. Moreover, there are many energy sector challenges, which are getting more critical day by day. In order to overcome from such critical energy issues, different strategies are identified by several researchers in the built environment. One such strategy is use of biogas, which advances waste management and it also helps to reduce the solid waste management issues pertaining in the current society due to lack of waste dumping yards. Hence, this paper aims to present the potential of implementing biogas for the apartment buildings as a sustainable energy and waste management solution. Qualitative approach was followed along with the case study strategy. Seven cases were selected for the study purpose. Solid waste types, source of solid waste, waste management procedure of the apartment buildings were identified. Further, under biogas implementation in apartment buildings, benefits, barriers and strategies to overcome from the identified barriers were discussed. The results suggest that effective implementation of biogas system for apartment buildings is a precise solution not only for waste management issue but also for non-renewable energy issues faced by Sri Lanka
