Extracted text: 16 Which of the following statement is true about eco-properties of material production? * O co, footprint is the amount of CO, released into the atmosphere per unit mass of produced material. None of them. All of them. Embodied energy is the energy to produce unit mass of usable material. It is not feasible to estimate embodied energy via the thermodynamics of the processes involved in material production because the thermodynamic efficiencies of processes are quite low. The embodied energy can be found by monitoring the total energy input to the production plant and dividing this total by the quantity of usable material shipped out of the plant over a fixed period of time.
