How we’re guided

The 12 Haller principles

We’re guided by Dr. Haller’s journey of innovation that defined his revolutionary work. They form the basis of The Haller Model: our blueprint for a sustainable ecological and economical future, and you can see them all below.

1. Have Passion & Belief

Live your passion and believe in what you do.

2. Think Big, Start Small

Test your actions and learn from your mistakes on a small scale without risking great damage.

3. Create Self-sustaining ecosystems

Plants, animals & technologies should be interdependent and self-sustaining.

4. Waste Nothing

In nature there is no waste - it is man’s invention; so when you see it, use it or reduce it.

5. Think Biological, not Chemical

Use biological systems not chemical ones; use natural solutions.

6. Use Animal & Plant Perspectives

Look at problems from their perspective; imagine what is needed to make them grow and flourish.

7. Seek the Indigenous

Try to use indigenous plants and animals - foreign ones are likely to import problems.

8. Be Inventive

Be prepared to come up with and try out new ideas.

9. Use Local Knowledge

Learn from their wisdom, consult and involve them whenever possible.

10. Create Incentives

Provide incentives for people to do the right thing.

11. Think Local

It makes sense to have production close to the source of the material.

12. Make Economic Sense

Sometimes one project on its own won’t pay back but in conjunction with other projects it will.
