Striking a perfect balance between these three factors will help determine which are the most efficient when it comes to calorific value. Typically, the higher the calorific value of a product, the easier it will burn but not all are safe to burn, and not all will produce a high amount of energy. Soil, for example, has a very low calorific value.
