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.
