I am wondering how the folks here feel about charcoal as a renewable fule. I realize that it makes co2 and can contribute to deforestation and loss of humus in soil if over done.
What about charcoal production in a managed food forest. Thank you for your oppinion

Well Im not using the charcoal for fuel, but Im setting up part of my forest for the production of future charcoal for terra preta/biochar and hugelkulter beds. (probably spelling that wrong)

  Im going to use honest locust, as Ive read that once established you can continually harvest branches and have desirable fire wood, so Im sure it makes a good charcoal as well. they grow pretty good here also.

  Im not sure how efficient of a fuel source it is, so I cant comment there, but in the soil its effects are profound and last 1000s of years. also sequestering carbon. In my dry heavy soils it has an amazing impact....

managed appropriately, I don't see any problems with charcoal production that can't be rectified.  if coppice is harvested on a good rotation, all the carbon that is released is taken up again as the trees grow back.

but, like you mentioned, there are plenty of examples of folks going about it all wrong and causing all sorts of damage and degradation.  approach it with wisdom, knowledge, and respect, though, and charcoal production on an appropriate scale should work out fine.

I think I should have called this topic (growing yor own fule) because its realy a wider discusion (bio deasel, ethanol ect.).

Charcoal is not renewable, biochar is.

Charcoal is made from wood.  Wood is a renewable resource with responsible management.  Most forests would benefit from a 10% clearing of weak, sick growth.

Your right, but I disagree about the most forests part.  I forgot my ink making lessons regarding sumi.  Many around here are monoculture deserts.

So based on what most of you have said, making charcoal on a sustainable scale could be considered part of a permaculture system. It is definatly better than ethonol and some seem to be justifying even that.

Charcoal, ethanol, and plain old fire wood are renewable resources.  They cannot be raised in every climate or region, but in areas where they do grow abundantly, I feel that we must utilize them in preference to non-renewable fuels until technology brings us more economical PV panels.  I cannot justify putting $30,000 onto my roof to save me $500 per year.

well, charcoal done badly would easily be worse than ethanol done well.  either of those done badly would probably be worse than fossil fuels.  done really well, though, both charcoal and ethanol could be produced as part of excellent regenerative systems.  and, as John Polk pointed out, firewood can be used wisely, too.

sadly, the vast majority of all fuel use and production to date has been done in short-sighted fashion with extremely negative consequences.

Wood is an excellent source of fuel. We can grow it locally. No need to import it from terrorist corporations. You can even just use the dead wood on your land, the trimmings. The trees grow and sequester CO2. Wood releases it so they can use it again. CO2 is good. Without it there would be death - no plants.

Well, it hasn't worked out so well for Haiti or North Africa, but one could make the case that it could have if they had coppiced or at least replanted instead of just cutting and burning.

Charcoal is something I want to try making probably later this summer.

Ecologically, it seems to me that the emissions it makes as it goes from wood to charcoal would be significant and create a local nuisance. Of course, some of that could be burned off, but that would require more advanced equipment like installing a rocket stove afterburner.

It has the distinct advantage of being a local and renewable resource that is easily produced with the simplest of technology in most habitable parts of the world.

The reason it failed so miserably in Haiti is pure economics (or, rather, lack of economics).
Even though Haiti is a warm sub-tropical area, wood is the only source of cooking fuel for the poor.  They are so poor that they will keep the cook fire burning 24/7 because they cannot afford to buy a box of matches!  It is true that you can fly over Hispanola and SEE the Haitian/Dominican border...it is where the vegetation STOPS.  Obviously. soil erosion has also been a major problem.

Just asking for a clarification:

What is the advantage of good charcoal vs good wood for your intended use?

As an example, in a forge or a foundry, charcoal has definite advantages.  To heat a house with a woodstove, it would have definite disadvantages, haven already given up a significant percentage of its energy content.

Thanks in advance,

troy

What has happened in Haiti and other places is what is described as the “tragedy of the commons.” If a resource such as a forest or pasture land is considered common property to everyone, then everyone will try to get the biggest chunk they can. Sort of like everyone with the federal budget.
Now if you own your own land and are being a steward of the land then charcoal as a product of the land is not different then selling apples or any other product of the land.  Personally though I feel charcoal is a waste of effort as a fuel when a rocket stove would deliver the full heat of the wood. With charcoal a good portion of the energy is lost from the wood to produce the charcoal. If you have a need to transport the energy or have a market for the value added product that charcoal is then there may be justification.
The main advantage of charcoal is it is concentrated energy that is lighter per BTU than wood so is easier to transport.
Sort of like whiskey is easier to transport than the amount of corn it took to produce it.

If you're making lump charcoal from logs, branches and the like I feel it is a waste of heat, especially for cooking.  You can make charcoal out of corn cobs which is still a waste of heat but at least you're not using a tree. I'd rather turn a tree into a board,then use the left over’s for heating, cooking or compost.
IMO the best thing to come along are the wood pellets and bricks. They take sawdust or another bio-mass waste, for lack of a better word and use it for fuel. (also use sawdust for charcoal)
I saw cherry pits for sale this past winter to be used in wood stoves.

You don't use charcoal in a foundry or forge it doesn't maintain the heat you need. You use Coal and then different types of coal are used for different applications.

I see guys cutting down trees all summer long from hunting property to use as heat in their homes. I tell them, why don't you buy a ton of coal? Save your trees for lumber. They reply the trees are free. Oh really, your time & the saw alone are worth more than the price of a ton of coal, year after year.

  I work in the HVAC field and I'm a licensed Stationary Engr., I.E. Power plant operator. I see so much waste in the ECO green movement. All most of it is, is our tax dollars funding another study or equipment re-commissioning that should have been installed correctly in the first place.

I suppose if you ran a meat smoking process you could use the excess heat from the charcoal to heat water for some sort of hydronics heat letting the smoke cure your product.
Then you'd have an excuse for the charcoal as it would be a by-product of 2 or 3 processes.

You have to get as much work as possible out of a product/process as possible to make it cost effective.

Yes I know my wife told me duck is $2.99 a per pound at Aldi’s. I could have purchased 50 for what I have in the 10 ah 7 left that the fox hasn’t killed off yet.
Well that is unless you’re doing it for fun, then it a hobby. $$$

Is charcoal ethical? Not if it's lump charcoal.

I fail to see where the pellets are a 'greener' product.  Most of it is still being made by taking branches and logs and converting them into sawdust.  It is still wood, but not necessarily "waste" wood.

The pulp wood industry is often criticized, but quite often they have utilized the turpentine, which is a byproduct, to fuel their operations.

I've tried to make boards and its not easy, not with the saw I have anyway. But imo wood is still best left to rot and support more life in the soil

Correct, what use to be left behind laying on the ground is now used. Stumps are another portion that should be used as well. I have walked through plenty of NY's woodlots after a logging operation and the amount of stumps and branches left behind are a staggering amount.

Wood fuels are the only carbon neutral fuels that can even go carbon negative in the amount of sequestration they put in the soils of the managed wood lots.

Every other fuel we use is not and can not come close to wood as a fuel.

I'm planting more trees and planning wood fired bread ovens and pizza ovens now

Cheers,

not only do the stumps need to be left the slash either needs to be left on the ground or chipped in order to keep up the soil heath for the next growing cycle

Really?  Don't tell the many many primitive blacksmiths in africa.  They use what they can get, which is usually charcoal.  Also, don't tell all the shoestring, do-it-yourself casting/foundry/forge guys in this country who have used charcoal instead of "proper" coal, either because it's unavailable, or expensive, or they want to do it all themselves, or whatever.

I merely sited that as an example of why charcoal might make sense in some situations.

My foundry currently runs on propane, which I am trying to get away from.  My next design will run on used soybean oil, not coal.

Finest regards,

troy

prior to "fossil" fuels, biofuels were extensively grown on farms.
Some farms were solely biofuel farms.
the fuels were pasture, hay and oats to feed horses.
a hugh market was supplying feed to "city" horses.
with the advent of motor vehicles, (cars, trucks, tractors) a lot of farms went out of business due to the loss of their market

For years I used my own charcoal for blacksmithing.  Each morning I would harvest the charcoal from my wood stove, getting about a gallon per day.  Took about 3 days to get enough to complete a project.

You can actually use raw wood in a forge or foundry, with some qualifications: it is a good idea to have charcoal for forge welding, and you can only melt low temp metals up to aluminum easily with a wood fire. But if you are in a sustainability situations, you should be aware that you can work metal over a wood fire.

Charcoal = biochar, except some people would say it's charcoal till it's charged. Charging is done with some nutrient (especially nitrogen) rich liquid, like compost tea or urine. And generally, if you are using it for fuel you want the chunks bigger. Though I'm lazy, and don't crush it much. But then, I'm not against a slow approach, and will mulch with char as well. Eventually it will do its job.
