- Making Biochar using dry mulch
- 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
- Turn off the gas-out valve
- Fit the effluent bucket securely
A Brief History
It’s been two years since I began work on the backyard, and it’s been a chaotic process of trial and error and learning. My aim has always been to grow lots of food, but the ideas and ideology driving me have evolved at the same rate as the backyard.
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
