Dynamic energy LCA-based assessment approach to evaluate energy intensity and related impact for the biogas CHP plant as the basis of the environmental view of sustainability

The aim of the paper is to evaluate the energy intensity of a biogas CHP system, based on energy flow and estimated associated costs. This paper provides the energy requirements in the plant identify the critical point of the digestion process and estimate the amount of CO2 associated with the energy. The results of the study assist in 20% of heat reduction. For companies, energy LCA primarily serves to assist decision-making with a view to environmental sustainability.
