Respected Sir/Madam,
My name is Santanu Mukherjee. I am an aspirant for doing research in biochar & a research scholar in Ag.science.,But, please inform me the followings--

1) we are producing biochar from carbonaceous materials mainly from woody substances or any decomposed litter. here destruction of forest is obvious .then how it would be eco-friendly & cost-effective?


2) Biochar is produced in very little amount but for field experiments it requires in very large amounts (mainly in tons ) then how it can mitigate the large scale demands?

please reply .

your's faithfully

santanu mukherjee

For example, by using wild, inedible seaweeds where possible, and overgrowth vegetations, like water hyacinths, at overgrown waters:

Above link has instructions on how to make small cheap pyrolysis charcoaler from used small barrels. Main use of that Holon-model is that it shows how this pyrolysis works, so that people who have seen and studied it's use in one cooking, can then build different sized, and varied, versions of the same simple, smokeless principle. Many households using such, can together give greater quantities. This is a matter of organising such locally, whether by incentives for local and growing businesses providing biomass to area's households and gathering the biochar, or by peoples self organized projects.

If needing larger facilities than can be locally constructed, there are companies that deliver larger scale biomass pyrolysers, from which also the pyrolysis heat energy can be utilized. (for such I know one company that delivers globally... Preseco. Is it the best ? Is it with moth economic prices ? I do not know... I know of it because I live nearby it's offices and facilities and have followed some of it's doings and deals... so I'd assume there to be others as well).
 

please reply .

ok....

Question: "1) we are producing biochar from carbonaceous materials mainly from woody substances or any decomposed litter. here destruction of forest is obvious .then how it would be eco-friendly & cost-effective?"

Using trees as source for biomass for charcoal parts: That might not be ecological at all. Thus... instead plant mass from waterways can be used, especially from such waterways that have been chocked with too many nutrients leaking to them, and full of such plants like Water Hyacinths. Removing excess nutrients from places where they prevent diverse local ecosystem life functions from existing... and then in form of nutrient saturated charcoal powder, replacing them to such land areas that have been depleted and desertified by excess farming, logging, or unsuccessful land life management. That should be ecological, and instead of causing harm, healing and fixing the previously caused damages.

Question: "2) Biochar is produced in very little amount but for field experiments it requires in very large amounts (mainly in tons ) then how it can mitigate the large scale demands?"
Biochar, (and terra preta -type mixtures) can be produced in larger scales. I referred to two possible and available ways to accomplish this: 1. larger amounts of local small households each using a small self-doable charcoaling stoves for cooking and heating (with special attention: carbon monoxide is very dangerous indoors if, and when, it leaks... so yard/street-side/field operation preferred), gather their resulting charcoal amounts together, for example, once per week or month, and thus larger amount of charcoal has been collected for use in land. 2. Some facilities that turn biomasses into charcoal (while extracting the resulting heat for use as energy) are industrial scale powerplants, and they do produce larger amounts of charcoals. I mentioned that one company as example, that such medium scale powerplants are available already.

And the link I provided as practical Do It Yourself -type instructions, on how to physically do and test these (small scale versions) methods, and thus observe in physical reality, how effective they are, and in which ways, in particular area... and are they applicable at all therein.

Dear Santanu,

                    I feel very happy to reply you.

1.Regarding your first question, biochar can be produced not only from forest trees but it also can be produced from any type of biomass which include residues of all crops, tree liters and etc., we need not cut the use full trees which is grown near rode side and in forest areas and  but we can cut the unwanted trees which is grown in our agricultural lands viz., prosofis juliflora and etc.

   
2. regarding your second question, you are absolutely correct but we should promote the rural peaople to produce biochar in large quantity.

In addition i enclose herewith my power point presentation for your kind references.

If you want further details please call me at 09994853859.

with regards,

Respected Sir,
                     Thank you for your kind reply & help. Yes, sir I feel also very happy to hear from you. But, the unwanted trees like you are saying prosopsis sp. is not necessary to maintain genetic biodiversity?
 
please reply .
 
your's faithfully
