Life cycle assessment of biodiesel production using alkali, soluble and immobilized enzyme catalyst processes

► Life Cycle Assessment (LCA) of catalytic processes such as immobilized, soluble biocatalyst and alkali catalyst. ► Biodiesel production using immobilized biocatalyst has less environmental impact compared to alkali and soluble biocatalyst. ► The environmental impact of the immobilized biocatalyst depends on the reusability factor.
