Bio-char, the black charcoal like substance discussed so often in recent days for its miraculous effects on soil and compost - is good for more than just your garden. One of the key materials for a sustainable future of the planet, bio-char has many other uses that can be integrated into new organic systems for farming, building, clothing, electronics and a whole range of consumer products. Bio-char can initiate multiple cascades to optimize and recycle current material, nutrient and energy flows. It turns out that the stable carbon matrix that bio-char is made of has all kinds of interesting properties. This carbon matrix can hold on to things - water, air, metals and organic chemicals. And it also has unique thermal and electrical properties that are still being explored. Finally, the highly porous physical structure of bio-char provides habitat for microorganisms. With so many different properties, bio-char is bound to have a lot of different uses, but one function that all bio-char applications (other than burning it for fuel) share is carbon sequestration. This piece of manuscript searched out/found another technical bridge for value addition to the biomass of castor plant.
