4.3 Material Balances The first step is to look at the three basic categories: materials in, materials out and materials stored. Then the materials in each category have to be considered whether they are to be treat-ed as a whole, a gross mass balance, or whether various constituents should be treated sepa-rately and if so what constituents.
