**4. Conclusion**

The two processes described here, the NH3 and the protein recovery process from manure digestate, have shown the high recovery rates. Our processes can be directly applied to the current practice of the solid-liquid separation of manure digestate from which both solid and liquid are otherwise sprayed on lands. The protein recovery process can be applied to the solid, while the NH3 recovery process can recover NH3 from the liquid, with the solid and liquid coming from ADs which are rapidly being
