Treat Food Waste Digestate
Turn Waste Streams into Revenue
ZwitterCo’s superfiltration membranes enable concentration of food waste digestate.
Concentrating liquid digestate allows you to generate valuable fertilizer as a saleable product. Additionally, the concentration process can reduce hauling by >50% and saves water by providing opportunities for water reuse.
Our membranes extract tough-to-treat compounds from food waste digestate so that downstream desalination and nutrient recovery technologies operate efficiently.
