Beyond Renewable Natural Gas (RNG)
New membrane technology is at the heart of nutrient recovery. The leading digestate management solutions create value from the leftover water and nutrients after RNG production.
ZwitterCo’s superfiltration membranes help transition away from hauling and land application, paving a path to the future of sustainable digestate management.
Benefits of ZwitterCo Superfiltration Membranes
Reduce off-site hauling
Reduce digestate volumes and transportation costs by 50-70% with membrane-based solutions
Recover and concentrate nutrients
Our membranes concentrate NPK for organic fertilizer, The small volume of concentrate allows for easy winter storage and resale over ideal growing seasons
Improve permitting and compliance
ZwitterCo’s Unique Technology
ZwitterCo provides a core technology within the world’s leading integrated solutions for digestate management. Our membranes extract tough-to-treat compounds from digestate so that downstream desalination and nutrient recovery technologies operate efficiently, making it affordable to produce organic fertilizers and reusable water.
