[biochar!](https://extension.usu.edu/planthealth/research/biochar)
Its basically just making charcoal from woody wastes(i use my pruning from my garden).
[making biochar using a pit.](https://youtu.be/ROgHuYMfyoU) the wood becomes stable carbon and lasts hundreds of years. I grind it and put it in my compost then add the compost+biochar into my garden.

Biochar is cool and all, but it's still not as good as preserving the wood completely intact. The article you cited itself says "it is predicted that at least 50% of the carbon in any piece of waste turned into biochar becomes stable," which is quite a bit less than 100%. I suppose it's good for the twigs and other leftovers that aren't even good enough to be made into OSB or MDF panels.
