You have to carry out a Life Cycle Assessment of the "Production
of ammonium nitrate from Natural gas"to calculate the total energy consumption of the process and
make a poster for the same. System Boundaries are from Cradle to gate i.e.
from raw material production to factory gate, and does not include the impacts
of further supply chain or distribution mechanism. You have to estimate "energy
consumption per unit production" that have incurred (directly or
indirectly) during the process.
