Superfiltration Membrane for Food Waste DigestateA new era for food waste digestate management.

Biogas facilities can achieve lower carbon intensity scores by more sustainably managing digestate, whether through reducing offsite waste hauling, preventing the overloading of nutrients on soil from land application, or achieving wastewater qualities safe for discharge or reuse.

Water reuse, like landscape irrigation or other nearby demand centers, helps offset freshwater consumption to better preserve local water resources.

Filtration solutions that leverage our Superfiltration membranes can recover and concentrate nitrogen, phosphorus, and potassium (NPK) for use as organic fertilizer. Simply store the concentrate over the winter, then use or sell it during the ideal growing seasons.

It’s a sustainable alternative to chemical-based fertilizers, known to be harmful to the environment, plus a new potential revenue stream from what is otherwise a waste stream.

Filtration solutions using ZwitterCo’s membranes are some of the most space-saving and “footprint-flexible” digestate solutions.

Membrane systems can also be entirely fabricated offsite; gone are the days of outward expansion with high upfront capital costs and long onsite construction jobs. This leads to simpler permitting and facility design for new urban biogas projects.
