Rasmus,
Thanks for the wiki contributions. Can you add some info on Pelletized Biochar ?
Our proposed route is continuous charcoal production on a desktop scale by making pellets first, then using them in hydronic stoves to generate heat while producing charcoal in a continuous process. This has great potential for wide adoption because the plant size is reduced significantly, and we'd like to prototype a desktop bioachar maker this year, such that it's a practical part of any home.

- On the note of to crush or not to crush, i think it depends on what the goal is:
- If your goal is Carbon Sequestration / Fill probably not (Although if compacting it a ton, a fine powder may sink less?)
- If your goal is for it to be mixed into the soil well and upgrade that soil to SABE ( Terra Preta ) a fine powder is probably best
- GRANTED citation needed
- In terms of knowns:
- "How Permanent is Pyrogenic Carbon in a Live Soil" is one of the big concerns in Biochar as a Means of Carbon Sequestration , uncertain on the current state of the art on that
- Surface Area is your Friend*
- Only unknow of this is what role coarse debris/rocks would play in a Soil
- Might help stabilize soil/prevent erosion, also do larger chunks hold onto water better?
- The ORIGINAL Amazonian Black Earth Soils also had Terra Cotta / Pottery Sherds so that may be a relevant piece of the puzzle, not powderized charcoal
- Ways to go about it all:
- Pre-Grinding of Waste via a In-Sink Wet Waste Grinder
- Post-Grinding in a Yard Waste Grinder / Consumer Level Electric Woodchipper (Coarser Grind, but low complexity+maintainance concerns)
- Post-Grinding via a Hammermill (Especially with higher Air Classifier integrated models can produce a very fine, consistent mix. Bit of a maintenance / Combustible Dust Explosion + Fugitive Dust Emissions concern
- Also unlike other methods could probably NOT handle Wet Charcoal well due to clumping/clogging concerns
- Post-Grinding in a Ball Mill
- Would probably have to be in a Batch Configuration, and is LOUD, but could be done with Wet Charcoal and get to any desired Particle Size
