| dc.description.abstract | The raise in population, technology and infrastructure development is directing the present towards the future of high energy demand. The reduce the consumption of the fossil fuel, renewable energy sector should be boosted for a green and clean future.
Bioelectrochemical system has been proven an effective technology for biogas upgrading. Therefore, it is necessary to conduct life cycle assessment (LCA) studies based on the BES system for biogas upgrading to evaluate the potential for the purpose of commercialization.
In this study, two systematic literature reviews were performed i.e. BES system for biogas upgrading and the LCA of BES system, to understand the fundamental and gap of the BES system for biogas upgrading and LCA. Most of the research papers were found on Scopus and Web of Science using search strings.
The objective of this research is to conduct a life cycle assessment using for the bioelectrochemical system for biogas upgrading. The LCA is performed using OpenLCA software and Database from Eco-invent. The cradle to gate LCA study includes the impact categories such as Global warming potential (100a), Acidification, Eutrophication and Human Toxicity potential using CML-IA baseline method.
It is difficult to evaluate the LCA of lab scale-based experiments due to the small input quantities, therefore the input components were scaled up and normalized the system operation for a year. Platinum showed the major contributor to Global warming potential, acidification, eutrophication and human toxicity. A comparative LCA study was performed in between platinum and nickel contribution to the environmental impacts. Platinum has shown higher contribution to GWP, acidification, eutrophication and HTP as compared to Nickel. | |
