Explanation:
Detailed explanation-1: -3 Calorific Value/Heating Value. The calorific value of LFG can be defined as the amount of heat produced on combusting a unit volume of gas and can be expressed in kcal/m3, kJ/m3, or BTU/ft3.
Detailed explanation-2: -the calorific value can be calculated. For other foods (e.g. meat products), it is measured using a device called a “bomb calorimiter". Essentially, you put the food in a chamber filled with pure oxygen and burn it, measuring the amount of heat (i.e. energy) that is generated.
