Wondering if anyone has tried to make charcoal from coconut husks in the DR? Here is a method:

Hello fellow smoker/bbq/grillers! Here is the recipe, as requested, to make your own Lump Wood Charcoal (thereby saving yourself tons of cash, and successfully robbing the "Kingsford Mafia".) To make 30-40 lb of charcoal, you will need:

A clean 55 gallon metal drum with the lid cut off roughly (you will be able to reuse this drum many, many times)
Enough dry coconut husks/shells to fill said drum
A bag of sand
3 or 4 bricks
A case of beer(optional)
Time and patience
Start by punching/cutting 5 holes in the bottom of the drum which are each 2" square. Try to keep them towards the center. Put the drum down on the bricks, placed so it is off the ground and fill it with the wood. Start a fire in the drum. When it is going well, put the top back on to reflect back the heat. Since it was cut off roughly, there will be slight gaps to allow the a draft.
Now, turn the whole thing over, placing it back onto the bricks. (This is where you might need the case of beer to convince several men to help you lift the sucker. It will be heavy. And mind the lid doesn't fall off!) Wait, consuming the beer as necessary. The smoke will start out white. This is the water vapor burning off. Next the smoke will go blue/grey which is the alcohols and phenols burning off. Then the smoke appears yellow, which is the tar burning off. Finally the smoke will clear and you will just see waves of heat. When this happens, Carefully remove the bricks out from underneith. Take the sand and make a pile around the bottom lid, plugging up the bottom draft. Also, cover the top with either a piece of turf or a large piece of metal. Use the sand to seal around the turf/metal so no air can get into the drum. We are trying for a closed system here. If air/oxygen/fire-fuel DOES get into the drum, the charcoal will just burn up. Not what we want. Also, try not to let the sand fall down into the drum through the holes. Allow the drum to cool (2-3 hours). Then turn back over, pry off the top and remove your charcoal. If there is a spark, the charcoal may "catch", but just douse it with some water. The charcoal will still be hot enough to dry out. Repeat above process as necessary.

That's allot of work when you can just buy charcoal in the stores.

Interesteng though

That photo is of Richard Johnson's (Kamado) charcoal, correct? It looks like his earlier, better quality Indonesian stuff. I still have a few boxes left over from a bulk purchase a long time ago. Subsequent incarnations weren't as successful as the earlier production due to a fall in burn quality, BTU output, ash production, etc. You can read all about it on the Naked Whiz' site. (Google it)

I have posed the same question before - Why isn't a similar product manufactured in the DR? I think the answer is simple in that the right entrepreneur just hasn't arrived yet. It is a perfect idea for the DR as the demand is there as is the raw material, and it's very "enviro-friendly" in that no trees are cut to make charcoal.

Why not just buy charcoal? It's usually produced illegally or imported from Haiti which is now nearly completely deforested. If they could porduce charcoal exclusively from coconut husks, you would have a sustainable source of cooking fuel for the rural population and eliminate the demand to import charcoal. Things are so bad now in Haiti that in certain areas they are mining tree roots.

This is an industry that could work for an inverstor. It would have to start in the DR because it's unlikely that there would be a supply of husks in Haiti yet.

The photo btw is from Indonesia I think. There are a lot cottage industries making it now in all shapes and sizes. Thanks for the link info...

I looked into Bamboo, but it has to be five years old to be usable. Coconut is good because it is a waste product and you get coconuts as well. They also make charcoal briquettes from jatropa waste, but I don't think they do it on the island yet. I think the idea fuel would leucania since it can be coppiced annually, but in Haiti the trees were inevitably cut down and stolen for firewood.

This is the kind of technology that is desperately needed in the DR and Haiti, but doesn't attract foreign investors because there is no export market for it. One issue could also be transporation costs to where the demand is.

Some numbers on coconut charcoal when sold as activated charcoal:

Processing of Coconut Shell into Activated Carbon/Charcoal

"Generally, coconut production at farmer level is

1 ton/ha, with coconut shell by-products of 0.9 ton, which in turn can yield 0.36 ton of activated charcoal. Price of activated charcoal US$440.00, income obtained is US$158.00"

It could then be pressed into briquettes which maybe sells for $100/ton, maybe more. That would be a nice bonus to someone who already has a coconut plantation.

It's not exactly high tech or expensive equipment. Just a 55 gallon drum and something to grind the charcoal and they can make the briquettes by hand.
