Hello Kim, It's a nice opportunity in the field of biochar. We found in research that sewage sludge biochar producing in pyrolysis temperature 320 ℃ is the highest container of available phosphorus. B

All, Beef production using feedlots is growing fastest in developing countries. Research in the US is ongoing on how to fix the CH4 and N2O emissions. Sounds like an opportunity for biochar. Kim From

There are also other situations, such as windy days that whisk air away from a field, but the really crucial point is whether feeding charcoal to cows removes part or all of the methane and as another

#methane #cow

The photooxidation won't happen at night. Methane (emitted from soil or livestock) is lighter than N2 or O2, so even if daytime photooxidation is rapid enough to remove methane, nighttime emissions wi

Hello all The attached “declaration” by Walter Jehne, Healthy Soils Australia is maybe available online on some website ? I would like to repost it on our web and social media sites If it’s not alread

Robert, No, What mainly led me conceptually to develop the Winwick drillhole technology was the need to process the microalgae that would be grown in my cost-effective Winwick bioreactors. When I saw

Sev, Thanks for continuing the discourse. I haven't been so fascinated by a technology since I went through the Navy's nuclear power training program. I would love to delve into supercritical reaction

Hi Trevor, Possibly, but seaweed-derived food, fodder and chemicals have a much higher value use than as biochar. Apart from simply drying and pulverising the seaweed for these markets, the valuable n

Robert. Thanks for your observations. Yes, depending on the rate of pumping, each drillhole reactor could produce up to hundreds of tonnes per day of biochar. Because of forest waste biomass collectio

Sev, I read more of your paper and think your concept is awesome. It seems you could make many tons of biochar per day with one of these. Finding existing infrastructure to demonstrate and optimize th

Hi Robert, To reach close to the supercritical water conditions, 220atm and 374C, needful to transform biomass into biochar, water and some CO2, an aqueous slurry-filled drillhole reactor needs to be

#hydrothermalcarbonization #methane

Hello Sev, Without reading everything, I was hoping perhaps you can offer a few key details. The drillhole reactors, which are miles deep perhaps, have material loaded into small tubes for charring? I

Thanks, Robert. Nice to be so welcomed. Regarding new ways of producing biochar, would some in the group care to assess my Winwick Hydrothermal Carbonization (WHC) method of producing industrial-scale

sevclarke, Welcome to the group. I hope you will stick around and provide more of your out-of-the-box systems-level ideas. There are so many potential uses of biochar. New ways of producing and modify

Tomaso, Further to my reply, should your source of natural gas have a substantial carbon dioxide content, you might care to use NovoNutrients technology that ferments CO2 and hydrogen to produce bacte

Hi Tomaso, It is not my website. As far as I am aware, MM has not considered the use of its technology to provide carbon-negative natural gas. There are also other methods of splitting methane. You wo

As a newbie, could I ask whether anyone has done, or would be prepared to make, the assumptions and calculations regarding what percentage of the geochar/biochar/carbon black (produced using plasma po

The calculation of CO2 e is complex and best left to IPCC reports. The IPCC 4th assessment provided CO2e for 10-year, 20-year, 100-yr, and 500-year. The CH4 and N2O CO2 e values in IPCC 4 were: Specie
