Before I roasted coffee for the first time, I had never seen green beans before. They were smaller than I expected, heavier too, and they didn’t smell like coffee.
“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
“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 flammable gas
- Creates fertiliser
- Runs on kitchen rinse water
- Safe and Clean
