How is our Biochar made?
The feed stock is plantation Pine and Douglas Fir; the Fir is only about 10%. It is mainly wood waste with a bit of bark residue, hence the presence of clunker.
The boilers run at 700 degrees. The biomass is heated in the chamber and the gases are burnt and the particles flare; and once it exits the combustion chamber it is quenched and creates the char. There are two boilers one produces a higher carbon content than the other.
Biochar is great for vege gardens (spread one heaped handful per m2). This Biochar has not been activated/inoculated so best not to spread too much at any one time. Biochar has a liming effect on soil so good for sweetening acid soil and breaking down heavy clays. Biochar can be used as a mulch, mixed with compost, worked into the soil or spread on paddocks.
Biochar is available in 40 litre bags.
