NetZro aims to address the huge problem of food waste and the many social, environmental, and economic issues that result from it.  The company’s biotechnology processes recovered food waste, reducing its volume, recapturing water, eliminating bacteria, AND preserving nutrient value. This allows NetZro to turn various food waste streams directly into new products for plant, animal, and human consumption that can be sold profitably. 

Venn’s PRI will help NetZro develop and deploy its first food waste solution at commercial scale.  This first solution would turn spent grain from Twin Cities craft breweries into commercial grade grain and flour.  The project has the potential to divert many tons of spent grain away from landfills, reduce greenhouse gas emissions, and create new high-value products from existing food waste rather than from new resources.
