It's an added benefit.

Yes! And adding an acid wash step (to decrease the pH) can increase the sorption even more!

Makes sense. One should probably think about the Ph level in one's soil, though.  We have very acidic soils naturally here, as do you, probably, in Seattle.

Totally agree - and knowing what the various plants want for pH too!

That's very exciting! I heard people once advocating for sinking logs under Antarctica, presumably to brute force carbon sequestration, but I love the idea of getting both the direct agricultural and carbon related benefits from turning to biochar production. Admittedly, I am posting while partway through reading this article, but I love peeking inside this matter of food waste digestate and issues at scale. It's stuff I simply never knew of before this!

Hugel culture works that way. So does putting rotting wood in the soil when you plant a tree. They are good for building the fungal content of the soil, which trees need.  However, in the carbon cycle, the wood will soon gas off into CO2.  One of the great things about biochar is that it's so stable in the soil. It sinks carbon for thousands of years.   Great for climate change that way.
