Waste coffee husk turned into a wonder material key to mitigating climate change
- elbigbad 3y agoThe most woo woo articles somehow get traction outside core hours.
- waiseristy 3y agoI would posit the woo woo just changes flavor outside core hours
- DemocracyFTW2 3y agoNot sure why you call woo woo on what appears to be a practical and promising method to both sequester CO2 and improve soil quality, and all this using a relatively low-tech and cheap technology with material that is already lying around the surface in abundance (crop residues). Nerds need not despair either since one can both just burn collected stalks and husks in a controlled way by piling, incinerating and quenching stuff in a controlled right on the land, or else do the same in a more closely controlled way monitoring temperatures and chemical processes. There's stuff to do for both the bottom-uppers and the top-downers here!
- rcme 3y agoCan biochar be made in a carbon-negative way? The heating process has to release some carbon, no?
- kragen 3y agoit'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
- tourmalinetaco 3y agoAccording 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...

- fisherjeff 3y agoThis is exactly the “drinking more coffee will save the planet” article I have been waiting for
- tomcam 3y agoI’m on the edge of my seat, hoping a similar article will appear featuring Mountain Dew with real sugar
- snapplebobapple 3y agoThat kinda feels like the only positive story would be off a really negative aspect. Something like it kills you quick with a heart attack or stroke in your sixties rather than long and drawn out and medically expensive affair of normal death from old age, saving medicair from insolvency.
