About Grainstone

A better future,
grown from here.

Australian ingenuity. Partnerships. Greater value from every harvest. Exporting to the world.

Our Mission

Making more of what we grow.

Grainstone began with a simple question: how can we get more value from the crops we already grow to help solve growing global problems? Australia produces exceptional cereal grains, yet valuable plant resources remain under-utilised. We see an opportunity to connect agriculture, science and industry to do more with less.

Our work in fully integrated advanced manufacturing biorefineries — creating valuable products from grain and straw drives towards sustainable intensification of agriculture and designing waste out of the system along the whole value chain.

We are developing pathways to food ingredients, renewable fuels and recovered nutrients. The goal is practical sustainability: products that meet real needs, economics that support adoption, and lasting value for growers and regional communities.

Founder’s perspective

An idea is only
the beginning.

Fossil oil refinery technology solved mega problems of last century.

Grainstone biorefinery technology helps solve mega problems of this century, leveraging Australia’s global advantages in cereal grain production.

Our story

Making more of what we grow.

Grainstone began with a simple question: how can we get more value from the crops we already grow? Australia produces exceptional cereal grains, yet valuable plant resources remain underutilised. We see an opportunity to connect agriculture, science and industry to do more with less.

Our work has grown from food and ingredient innovation into a broader vision for integrated biorefineries — creating valuable products from grain and straw while designing waste out of the system.

We are developing pathways to food ingredients, renewable fuels and recovered nutrients. The goal is practical sustainability: products that meet real needs, economics that support adoption, and lasting value for growers and regional communities.
