JUSTIFICATION: We have seen from the above two tables that is EE OF THE MATERIALS USED TO BUILD PROTOTYPE and Embodied energy calculation after using the recycled materials is 405.19 and 68.05 MJ respectively. The difference between the two tables energies is 337.14 MJ. As the embodied energy decreases due to reused components so we have used these as our new replaced products.
