Weba. For example, in some regions, wet and hence low calorific food waste may be source segregated while in other regions not. Where not pre-segregated, then this will lower the calorific value of the waste stream and hence impact the ACT’s efficiency. An ACT in one region may end up with a different efficiency to an identical plant in another. 2. WebSome of the data required to determine the heating value of a fuel have been previously determined.
