Biointensive Growing in a Permaculture System
Before I found out about permaculture, I was studying up on the bio-intensive method of growing food, and was about to dedicate the whole property to a biointensive farming system. As it happened, permaculture swept me off my feet and into a swirl of fascinating ideas and possible directions. As the dust settles now – as my head drifts gently out of the clouds, the bio-intensive idea is still glowing, but not as something separate from permaculture, but as a potentially integral part of it.

- Mulch is loaded into an old beer keg
“Biochar can be made cleanly and effectively on a home-scale, using a biochar retort.”
Biochar is a desirable material for anyone looking to improve their soil. Buried, it acts as a water retainer, nutrient trapper, and home for beneficial bacteria and plant roots, and it continues to support life and fertility for thousands of years! On a home-scale, biochar can be made from waste wood or mulch, using a biochar retort.
- Produces biochar – a permanent soil amendment
- Burns clean and hot
- Can be used for heating or cooking
- Can be fuelled with waste materials
- Close the gas-out valve on the digester
- Open the gas-out valve on the collector
What do I think it is?
Permaculture is a vector through which people can learn and apply themselves to affect change in a landscape toward a regenerative, life-supporting food forest system. Well at least that’s how I see it. It is a set of principles and techniques that is freely available to read about on the internet, and courses are run all around the world to disseminate its message.
But what is it really?
“Biogas is the perfect solution to modern sustainable cooking.”
Biogas is a mixture of gasses that are produced as anaerobic bacteria break down organic matter. It is flammable, capable of producing a clean flame for cooking and heating, and it can be derived from as simple a feedstock as your kitchen rinse water.
A biogas digester is a container holding water and bacteria, which can be ‘fed’ organic matter to be broken down, and which collects the resultant biogas, to be tapped off either to a collector for storage, or directly for burning.

- Creates fertiliser
- Runs on kitchen rinse water
