Biochar is a kind of charcoal that removes CO2 from the atmosphere, helping yield healthy crops and even producing abundant renewable energy in the form of electricity as it's made. This exciting climate change fighter is ready for scaling now. Entrepreneur Axel Reinaud outlines three ways to make this material more accessible to farmers -- so that our food system, energy grid and the climate can all reap the benefits.

All those branches and twigs from plants hold a lot of empty air bubbles when transporting and transport is expensive. However the process of torrefaction and compression to briquettes afterwards is a solution for this. Torrefaction can be done locally (even with microwaves) and is not high tech. But a good pyrolysis oven is high tech if we want it to produce methanol or sulfur poor fuel..next to biochar.

@timothyblazer1749 2 жыл бұрын

Look up "rogue biochar". Thing is, you should add small terra cotta beads as well. I'd say about 10% by volume. Plus, to activate your biochar, you can do it anerobically, by covering with hot material ( green or manure material ) Plus a bit of flour and water ( 50% water by volume) in a sealed container. Make sure there is a small, cloth covered vent though! After a month, mix that nasty mess 50/50 with your Texas clay dirt, and dump it into the pit you dug to get it. :-) save the liquid for fertilization. Apply it daily until it's exhausted. Then plant the bed, after letting it rest for at least a few days. If it still smells nasty, wait until it doesn't. The CO2 thing is BS marketing. It's just great for your soil.

It’s actually commercially available. You can make your own, then dump it in your compost pile, then use it in your plot of land.

@ChristianPanero 2 жыл бұрын

Usually in a pyrolysis plant a fraction of the biomass is burned to produce heat, or another fraction can be gasified to produce a syngas. Both the exhaust gases from the burner and the syngas produced by gasification do not contain oxygen and they are hot. So they can be used to heat up the biomass to produce char.

Let's have the presenter identify specific ways to create 'sustainable' charcoal and how to properly integrate it into soil for increased food production. This is imperative, or there is no point. He speaks of what can be done. I want to hear how specifically it is to be done and if it's even applicable to be done per soil type. Half truths are often a great lie. I think, true biochar in the right environment can be significant to soil improvement but burning a buch of stuff for the sake of burning stuff with with no foresight is a fallacy. How is this suposed to work?

@TheEmbrio Жыл бұрын

Continue your research even just right here on youtube for exactly how low tech or high tech the process can be. And how to soak it to be full of good biology and how to integrate it is compost and soils.

Reduction is imperative, but we’re at the point where we need to take a lot out of the atmosphere, the ocans have already acidified, the temps are 1 celsius above 1975

@davidhunter5062 Жыл бұрын

The key is to take biological refuse (think fallen trees in a hurricane, wood chips from tree removal companies and utility work, yard waste, etc) and change it into pure physical carbon (char) rather than CO2. CO2 occurs naturally when you burn it to ash or let it lie on the ground to decay. The carbon is “captured (not released)” when you turn it into char through a process called pyrolysis. All that carbon is locked in the char…and cannot combine with oxygen to form CO2 (CARBON dioxide!!!)

Um, how is this any better than just mulching or composting dead plants? How is generating _more_ heat a good thing? Lots of other things already generate heat (eg electronics), why not try to capture or divert those unavoidable sources of heat instead of making more? If you want to burn plants (hopefully already dead), then at least try to find ways to reduce how much heat other stuff (like lighting and transportation) generate.

@@fairlanemuscle Can I ask you to consider the vast volume of water the oceans would have had to swallow, given any sea ice does not add to the level in the same way melting ice does not brim a glass if it melts, so all those mega kilometers of water volume can only have occupied the most northern and southern land masses (lets give it a generous half the total land mass @5% total area) so we need to explain a 95-5 volumetric increase ie; 90% of the planet rose by hundreds of meters with a volume ONLY drawn from 5% of its surface!
