GRASSA – Building a greener, more resilient food system.

Local leaves.
Global impact.

About
Grassa

At Grassa, we’re building a greener, more resilient food system from farm to fork. We unlock the full potential of grass, the world’s most abundant and protein-rich crop, transforming it into high-value ingredients for animal feed today and human food tomorrow.

Developed in collaboration with Wageningen University & Research, our technology enables farmers to create more value locally while reducing the environmental footprint of feed and food production.

Local leaves, global impact — that is our vision: use what grows abundantly around us to nourish a growing world, sustainably, affordably, and locally.

Why
Grass?

Grass is the world’s most widely cultivated crop, yet most of its most valuable nutrients remain underused. It delivers one of the highest protein yields per hectare, grows across seasons, and is supported widely by a fully established agricultural system, from harvesting machinery to logistics and on-farm expertise.

The Grassa processs

Grassa is not building a new food system from scratch.  We are upgrading the one that already exists.  

Our solution integrates directly into current dairy farming operations, making implementation practical, low-risk and immediately scalable. No new land. No complex restructuring. Just a more efficient way to use what farmers already grow.

  Freshly cut grass is taken to a nearby press and separated into two streams: protein-reduced fibre returns to the farmer as optimized feed, while the juice is centrally refined into functional ingredients, turning one harvest into multiple value streams. 

Scale-up timeline

Founded in 2014, Grassa spent a decade researching and refining the technology that makes grass-based ingredient extraction practical and scalable. That groundwork led to our first pilot press in 2024, and our demo press, opening spring 2026, is the next step.

Our model is simple and repeatable: local presses close to farms, feeding into a central refinery for ingredient production. Decentralised where it matters, centralised where it scales.
