Couple of photos 6 weeks apart. Bucket is 20 litres. Added
to the water has been some pee, cow poo and a tablespoon of molasses.
First photo was 2 weeks after adding the char, second is 6
weeks later.

Approx 80% of the char has now sunk. The rest looks like sinking in another fortnight.
The sunken char is much easier to break (in one hand) than the material still in dry storage.

This char was produced at high temp

This site www.biogasworks.com is the portal for the carbon cycle activities of Chaotech Pty Ltd.

Our slow carbonization pilot plant is now rated 40 to 60kg charcoal per hour for lightweight feed such as sawdust. The specification particle size limit is 8mm largest dimension. Process simulations have produced a yield of ~40% char on a dry mass basis with ~80% total carbon content in the char.

I was surprised that there were no how to's for charcoal productions without the need for kilns, drums etc, so thought this might be of interest to some as a trial technique. It is not very efficient by way of volume of charcoal to volume of biomass to start, but can be useful if you have quantities of garden waste such as prunings, bark, leaves etc. This type of stuff normally goes into green waste, or needs chipping to compost or use as mulch as it is too big for compost bin.

This is a process I have used which requires only an open fire or fire pit, shovel or rake and water (hose or steel buckets with water). It is a minor modification of the techniques used when cooking using the camp oven - which only uses coals instead of flame. Instead of transferring the coals to the oven pit, they are wetted down to stop burning, and create charcoal.
