This work aims at proposing a combination of renewable technologies to partially decarbonize the process of four Indian factories that produce plastic closures in 2030. The first part is dedicated to the study of the closure process and the related input energy vectors. The energy consumption and the emissions are normalized to the production for each factory to have a comparison and to detect which factories require a strong emission reduction. Chosen the factories and basing to the location (India), photovoltaic panels and Proton-Exchange Membrane technologies are proposed, together with a suitable storage system, and their productivity is studied using formulas and parameters taken from literature.
