Biochar Interesting study on biochar. Thinking outside the box is potentially going to revolutionize the mining bizz. Mark and the team are ahead of the game here IMO.
“Biochar can draw down carbon from the atmosphere into the soil and store it for hundreds to thousands of years,” lead author Stephen Joseph, visiting professor in the School of Materials Science and Engineering at UNSW Science, said. “This study also found that biochar helps build organic carbon in soil by up to 20 per cent (average 3.8 per cent) and can reduce nitrous oxide emissions from soil by 12 to 50 per cent, which increases the climate change mitigation benefits of biochar.”
The global biochar market accounted for US$1.5 billion in 2019 and is expected to reach US$3.7 billion by 2026. But we need to produce more biochar—and use it wisely—to take advantage of all the benefits outlined in this fascinating study. Governments and authorities need to step up and take note of this useful negative emissions technology. https://www.treehugger.com/biochar-study-efficacy-global-drawdown-5197282
