A process-level LCA for evaluating the contribution of digitalization in the greening of a manufacturing system

Life Cycle Assessment (LCA) methodology is usually applied to products’ lifecycle and value chains to identify their environmental performance and identify circular economy strategies and options. As a result, different product configurations and strategies may be evaluated and compared, ensuring a positive environmental balance. However, LCA is not usually focused on a manufacturing process level. In this study, LCA is performed at a process level to assess the correlation between digitalization and green manufacturing. The GaBi professional database was used for assessing the manufacturing gate-to-gate processes.
