Manure treatment Sphere

Sustainable dairy farming Lely Sphere is a circular manure-handling system for separating mineral streams and creating value from emissions. The system separates manure and urine and converts nitrogen emissions into valuable fertilisers. You can use these for precision fertilisation. In this way, you improve closing mineral cycles as well as barn climate. Capturing and converting emissions Enzymes in the manure convert urea in the urine into ammonia. This vaporises within a few hours. Any ammonia emissions captured and converted into circular nitrogen fertiliser do not need to be compensated for with purchased fertilisers. Test barns show that reducing ammonia emissions by more than 70%, compared to official standards, is feasible. This resulted in a preliminary emission factor on the RAV list of 3,6 kg NH3 per animal place a year. With this you can ‘harvest’ 10 kg to 20 kg of nitrogen per cow per yea How the system works The Lely Sphere system separates three mineral streams. The urine, containing potassium, the faeces, containing organic nitrogen and phosphate, and fertiliser-grade mineral nitrogen in the acidified solution of the filter system. You can use each type of fertiliser to feed the soil and crops optimally, exactly when and where this is needed. A healthier and safer barn climate The barn has cleaner and fresher air, because the natural ventilation remains and doors to pastures can stay open. Lely Sphere extracts the manure gases. This makes the air healthier and the barn safer, because no gases accumulate under the floor.
