1. Related to material and energy inputs table: based on the functional unit how we can calculate the required amounts for all processes /flows. for eg: FU is 60,000 plants annually how we can calculate for infrastructure(steel structure, plastics) because life span will be like 10years and 15 years . suppose if I consider FU as 1 kg of leafy greens; how can I estimate amounts for energy and material inputs?
2. similarly one more doubt is how to give emissions values emitted from different process to air, water, land(how to calculate these values in order to give in outputs in inventories table)
