6. Also, is what is washed from dung better, same, or worse for energy content than what is left in the washed dung? This has probably been studied, but I do not know that answer. Anybody? [*] From my dung washing experience (along with compost, AD digestate etc.) what is real important is how the material is handled. If it is allowed to pick up dirt and sand (does so very easily) and if that remains on the screen could greatly lower the energy value. Compost typically has 50% ash and most of that is dirt and stones. Dung can have much more. Also the amount loss during washing depends on what the animal eats and its digestion system. Cow will mostly get washed out where horse will have a lot left for use. I think handling is most important as to final quality.
