VunaNexus uses a patented technology to transform human and livestock urine into two valuable products: a fertiliser free of all dangerous pollutants and water that can be reused, this while drastically reducing ammonia emissions and water pollution. The main product is a turn-key solution for onsite urine treatment and recovery replicating biological processes. This is the only technology on the market allowing for efficient treatment and recovery of high quantities of separated urine. Secondly we provide support with the planning and maintenance of the system. Our process allows the direct production of a hygienically safe, certified and marketable fertiliser called Aurin without the need of any chemical input. It is the world's first officially approved urine-derived fertiliser.
