Can biochar be made in a carbon-negative way? The heating process has to release some carbon, no?

  it's carbon-negative if you include the process of plant growth that produced the biomass basically the carbon-negativity idea is that the charcoal isn't biodegradable so it will stay out of the atmosphere for a long time. also you can burn the gases produced (which actually contain most of the carbon) to keep them from releasing methane

  According to some light research, and as is common in science, the answer is “yes, but…”. The trailing “but” being that it all depends on proper utilization and the project in general. While biochar is carbon-negative, if there is enough carbon-positive emissions in a project it could offset the biochar, for instance. https://www.sciencedirect.com/science/article/abs/pii/S0048969721061362 https://www.sciencedirect.com/science/article/abs/pii/S00489... https://pdfs.semanticscholar.org/fa23/220228abece8782396d287548885f3424dc2.pdf https://pdfs.semanticscholar.org/fa23/220228abece8782396d287...
