FREE FUEL for the wood stove (plus biochar!)

Important reminder that this can be dangerous. So if you aren't going to come at it in a slow, careful, observant and iterative way until you have a feel for the process, don't come at it! Read the description for more details on the 'retort' we use and ideas on how to size and source them.

are there commercially sold heaters like this that reduce the risks and allow for less monitoring, etc?

[@tarinatupanen]

I live in Finland, we have about minus 9 degrees Celsius here right now, that is 15,8 degrees F. We have already had minus 27 C (minus 16,6 F) here this winter. We heat our home mainly with an oven called 'pönttöuuni' in Finnish. We heat it only in the morning right now, twice a day if it gets over minus 15 C. It has been made with bricks and has a metal shell. The bricks keep the warmth in them for hours, so we don't have to heat it constantly. Saves a lot of firewood. You can also buy metal bins that fit inside it from the hardware store, to burn wooden pellets and such in it, quite similar way you do in your oven, but more safely. I recommend googling pönttöuuni, you will get lot of results and pictures.

[@edibleacres]

Looks like a beautiful stove!

[@amatagreen8819]

Brilliant! Have you considered drilling a few small holes in the hotel pans to allow the syngas to escape the pan easier? Additionally, if you dump the biochar out while hot (outside in the snow or somewhere safe), and quench it with water/snow, then you are also causing the biochar to open its pores more, which will bring you greater benefit in the soil. You can also use the biochar anywhere you want to reduce smells like manure piles. I assume when you clean the chicken coop you are taking that inoculated biochar straight out to the field--yes? Wonderful video, love what you're doing. :)

[@fromthehutt9508]

We also use only wood to heat our home and use less than 3 cord of wood per year. Interesting to see a method that could further reduce our consumption and provide charcoal. You do a really great job of using your resources efficiently and reducing your waste stream. Love your ideas, keep up the excellent work.

[@kenyonbissett3512]

Imagine if you could reduce your cord wood down to 2 cords and then burn enough wood chips that the resulting “biochar” pays for the cord wood plus some. Another form of income. Amazing!

[@anonymous-pr2sy]

do you have any issues with creosote buildup in the chimney from running strange fuels in the retort? Ever put pine in the retort?

[@nicolassanmillan8460]

I’ve been doing this for a couple years now since I saw your other videos on the topic. It’s been working absolutely well for me and it just feels right as it reduces emissions and produces such good charcoal (which btw makes great bedding for the worm bin). I’d say the most dangerous moment is when you pull the tray out while it’s burning hot. I use good gloves and protective glasses since the lid could move a little bit and let the hot gases out. Protect your eyes!

[@edibleacres]

The key is to let the fire settle and relax a bit around the retort before it comes out... That gives it a chance to finalize cooking any last gasses that may be in there as well.. Win win.. So glad you like this technique!

[@ericdee2525]

Ive been doing this with the hotel pans since your first video. Its been working well for us. I certainly notice a difference in wood consumption, but getting the char was our main goal. We have been soaking it in worm tea and adding it to our compost. The garden loves it :) Thank you both for the ideas!

Thanks Sean I’ve seen this on a previous video of yours and gave it a go last winter ( summer here in Australia at the moment). Loved the the results - amazing turning bones into charcoal and keeping the same shape. I had fun experimenting with different materials!

It's amazing how things come out perfectly intact. We put in clothing and it comes out where you can see every stitch! Printed paper still has the writing on it, pine cones are a dream :)

[@annehartmann6572]

We tried this after seeing one of your first videos about this - in an old metal pot with a metal lid we didn't use anymore, the lid fits loosely. It is always the last filling of our wood stove each day and we then take it out the next morning, when it is cool to the touch. It is amazing to hear it roaring, while it is heating our home.

[@edibleacres]

Glad it has been working well for you. We don't let it go overnight, I think somehow it feels safest to be in the room or around and awake whenever it is running, but maybe you've figured out a good system that feels reliable and safe for you...

This is EXACTLY what I do... I use a Le Creuset cast iron pan, filled with sawdust or nut shells, which when done, goes in my compost.

I'll see if I can find a small one for our Clearview Vision 500. People need to know this is CARBON SEQUESTRATION, one of the only ways you can reliably take CO2 out of the air 'for ever' if Amazonian 'tera preta' is anything to go by, some is dated at 1000 years old.

So cool to hear you've been working with this basic system, sounds like you've got a great system you've evolved... Yeah, we all have to be super careful with this system!

[@Dontreallycare5]

Good tips for getting dual usage out of making biochar, certainly a lot more practical than using the in-ground methodology. Have you considered adding on a catalytic combustor to your stove setup? The secondary combustion area might actually really benefit from the syngas you are creating from the container materials and step up the cleanness of the burn to another level - I know when I finally convinced my grandfather to install one he had much less chimney cleaning to do every spring because of how much more efficient burn it created.

[@edibleacres]

I'd be open to / interested in the catalytic converter idea but I don't know that our older stove would work with iit... Hmmm...

I have a catalyst in my stove currently, though I'm pretty new to it. Since my catalyst is inside the stove itself, I've been wondering if the flames coming out of the retort are too much too close to the catalyst? As the manual for the stove talks about the catalyst guard being there specifically to keep flames from directly hitting the catalyst. Do you have any experience with this?

Another outstanding video in the woodstove biochar series. I try to get the word out to as many wood heat folks as I can. They are usually a bit skeptical until they see it working. But after that... Well, heating your house with free, easy to obtain fuel is pretty impressive.

[@edibleacres]

I'm fully committed to this approach at this point. I always hope folks, if they decide to try it, are very careful and take baby steps, but once you dial in the work flow based on your own stove and charring material, it feels magical how much heat you get for free with all that amazing char to work with!

[@stonemonkey900]

[@denislosieroutdoors]

An idea I've been playing with for grinding charcoal is awhile back I pickup a used kitchen sink with a garberator that I have set up outside for cleaning veggies from garden and grinding kitchen scraps for my chickens been running bio char thru it into 5 gallon bucket so far works great planning on doing a video on it...

[@edibleacres]

Neat idea, if you already have that setup that makes a ton of sense to use for grinding char too. Should be slightly moist I guess so it doesn't make a ton of gnarly black dust.

[@denislosieroutdoors]

@@edibleacres yeah I run little water and kitchen scraps with the charcoal into a bucket then it all goes to the chickens... eventually it all comes back to the garden...

[@beebob1279]

Great idea and I never saw this before. I think two concerns I would have are. 1. Make absolutely sure the lid is set so that pressure doesn't build up. 2. Make sure when you take out the biochar to place it somewhere that can't catch fire as it cools.

[@edibleacres]

Great notes of safety... 1) The liid on the hotel pans generally 'rests' in a way that is perfect for this process, so long as it is aligned with no weights or other pressures/etc it works exactly right. 2) Should be put on a metal tray to be taken out to cool . Wearing welding gloves is critical and putting it on a dry surface out of the elements to cool gently is perfect. Concrete slab in a garage is ideal.

[@schatzihall6572]

I finally set this set up in my wood stove. I’m using a cast iron pot because I had it. I’m looking for used restaurant pans. I’m cutting up hardwood pallets right now for fuel.

[@edibleacres]

Please be safe and hoping this system provides you a ton of beautiful heat and long lasting charcoal!

[@NS-pf2zc]

Oh this is brilliant! So it creates heat as well? And the gasses emitted are hot enough to burn off before going up the chimney? I only ask for the whole emissions/ chimney build up thing. Sorry for all the questions, but I’ve never seen this, and love it.

[@RagbagMcShag]

I think it should be better to make charcoal with those woodchips and integrate them into compost/soil than just straight up burning them (which would release the CO2 much quicker and would probably not burn the stuff as cleanly). The wood-gas thats released from the chips should also burn quickly and relatively cleanly I would assume.

[@edibleacres]

Creates ample ample heat for about 1-2 hours depending on what is in the container. If run correctly every last bit of gas that comes out of the container is caught on fire and cleaned up. For the most part, the whole process sends up the chimney just about 0 smoke (visible smoke that is). When run properly it is super clean and nice and hot..

[@legrantjorge]

Thank you for the explanation.

[@willmcculloch6907]

I do this, thanks to a video of yours from a few years ago. It’s a great system but PLEASE wait until it’s cooled down completely - I veeeery nearly set my house on fire by not doing so. If in doubt: wait and let it cool more.

[@edibleacres]

So important.. The charcoal doesn't get ruined to sit and relax in the container in the stove even for a day or more... When in doubt, let it mellow and settle in temperature before interacting with it.

[@lindamunroe1431]

Ha ha. Yes cool before lifting the lid or you add oxygen. Best to quench with water when hot as that is the moment you can improve the biochar further. Bit tricky though, not for kids.

I love this hotel pan method , they last a long time. I used one gallon paint cans they have a short life in the fire. Bagged wood pellets are my preferred fuel, uniform size that doesn’t need crushing. I often use the finished product in potting mix.

[@edibleacres]

The only thing with wood pellets is they cost money and have some sort of glue in them, also the plastic bag.. .Hmmm... Maybe it's worth trying some wood chips or other true waste stream feed stock?

[@composthappens1400]

@@edibleacres Most pellets are simply pressed saw dust no binders are used, I can find them for $5 a bag. The ease of having dry feed stock is worth a fiver IMO. I often use the empty vessel as a can liner. I have massive amounts of trash bags from Starbucks coffee grinds most of the time.

Producing heat from the gases, valuable biochar for the garden and preventing waste Win, win, WIN. I even add the old dog bones to the char pot for conversion to valuable bone char. A fabulous sight and sound to hear the pan gas off and produce a ring of fire. Thanks for sharing your pictures and knowledge.

[@edibleacres]

We do batches with dried bones when we have them. They are so incredibly beautiful once charred, aren't they! Amazing how they keep their shape. I like to add one or two into an otherwise nice carbon rich batch otherwise they don't contribute much heat on their own. Thanks for sharing your experience here Linda.

Thanks so much for this share! Permaculture is at its best when open sourced! Question: I have a catalyst in my stove. I wonder if the flames that come out of the retort would be bad for that?

But of course when the retort is in there the flames are high.

[@bensonboys6609]

What’s really cool is this is very carbon negative and produces a useful product at the end. The trees get there energy from the sun and store it by pulling CO2 out of the air. Instead of the wood decomposing and releasing all that carbon back into the atmosphere when it’s metabolized, you burn it through pyrolysis. This decomposes and burns the lighter organic molecules, but leaves a significant portion of carbon behind. This carbon to my knowledge isn’t readily reintegrated into the ecosystem (a good thing), and remain as a carbon sink for quite some time. Instead of the complicated and expensive process of carbon capture, refining, and sequestration, this does all the same, is cheap, and leaves you with an actually useful product at the end. Good on you!

1. Do not handle the pan until it is cold. Be patient. Let it be. 2. Do not cram the pan full. Leave it loose, especially if using material such as dry coffee grounds, which pack pretty tight. Best to leave the material loose so it chars thoroughly. Frustrating to get a batch that only partially "cooks." 3. Question: Do you find you need to leave the stove's air intake wide open for the pan to cook well? Or are you able to throttle it down?

[@edibleacres]

I would encourage you to not use coffee grounds... Whenever you have material that is high in nitrogen it is so much better to feed it directly to your soil or compost... Consider this a tool for making charcoal only from things that are high carbon and quite dry to begin with, it will make the process much nicer. If we have good material in there and a healthy fire it runs hot enough that we have to throttle it down or it can get WAY too hot...

I think it is better to be safe any way and running it hot but not screaming hot has value for safety of the home, etc... The warping we've experienced with the container comes almost entirely from it being 'shocked' by coming out of the stove and going directly onto a very cold surface like the concrete in the garage. Now we put it on a metal tray near the wood stove to release the heat and slowly cool and that seems good. 4+ years with the original containers and they are still intact.

[@edibleacres]

I'd say there is an art to it, something that needs practice based on each stove and material being charred... That said... A healthy bed of coals, one or two smaller pieces of firewood on top and the container slid onto the firewood is a reasonable place to start. A container only filled a little the first few times reduces risk and stress. I can always add a bit more small firewood next to it as needed, way safer than overstuffing!

[@JanColdwater]

@@edibleacres Thank you! I think this is better than doing it in the yard for sure!

[@politicalpartyagnostic268]

Thank you for sharing 🙏🏻🌿🌺

[@HAYChloeDevon]

How are you starting them in the fire? Are you building a fire first and then placing the retort in?

[@edibleacres]

Yes, the retort gets put into an existing fire. Takes practice but I find a 'medium' strength fire with small wood available to keep things going is the perfect time to add a retort. . When in doubt, go with very little material in the container the first few times so it is safer and a shorter run.

[@abigailpip112]

Why don't you keep the pan of cooked charcoal in the house while it cools? It would provide extra heat

[@edibleacres]

I understand the reasoning why you'd want to, BUT I would suggest not in case any last gasses haven't finished burning off, and because it would be a potential burning hazard. Not enough heat to warrant the risk I think.

[@christianlandmark2461]

hey just wondering what material you are burning underneath the hotel pans to ignite whats inside, it looks like hot charcoals

[@edibleacres]

The charcoal making process is driven by standard firewood. If you watch the video closely it is basically a standard fire with the hotel pan on top

[@zachlloyd9392]

I wonder if that would work in an open fireplace? Or would that leave the off gassing to possibly come into the home? Se get really good drafting up the chimney and have never had issues with it wafting out into the room.

[@edibleacres]

I think it is quite reasonable to experiment with that, with a very small 'load' at first to get a feel, but the basic premise is sound. There was a product called 'biocharlie' that was meant for fireplaces. It was basically a section of 6" stovepipe with two ends and just a few holes drilled in. You may want to look at photos for ideas. Be safe!

[@zachlloyd9392]

@@edibleacres Awesome, thanks for the info. I'll look into it more, definaty do not want to blow anything up lol. I might look into a way to extract the gas as well and store for cook tops. Like they do with biogas.

[@zachlloyd9392]

@@edibleacres Well, I tested it with a tin can from dinner, put in a few thin slices of wood, placed the lid cutout down onto the wood, and put it in the fireplace, was amazing to see the gas being burned off coming around the lid in the can, turned out great, I quenched it a bit with some water then overturned the can to cut off oxygen. Only a handful of it was made, but the experiment worked, I could see the flame etc being drawn up the chimney flue. We have carbon monoxide detectors etc in the house so I don't think anything was making it into the house. Now to have everyone over for a big chilli or bean dinner, and I can use the can from the large beans next, or maybe go middle of the road and only go up to a 30oz can next. If we are going to use the fireplace, there is no reason NOT to make some extra. Right now what I have made is going into our compost bin. My wife hasn't complained about the compost since I added it.

[@Amoondar]

So you just add the container with unlit fuel into the already lit fire?

[@edibleacres]

The container is filled with carbon rich, dry material to undergo pyrolysis with heat contained in the wood stove and turned into charcoal

[@Amoondar]

@@edibleacres so amazing! Thank you!

Has any one else noticed a wonderful blue iridescence from bio charring pistachios?

I've seen it on black walnut shells for sure... Crazy blue/purple shine when the char is done, super beautiful.

[@jameskniskern2261]

I've seen it! Some hardwoods do this too.

[@bigal7713]

how long does it take to dry the wood chips and would you recommend using choosing the freshest ones or those aged a bit that already have leaves/needles decomposed?

[@edibleacres]

Ideal is to have a dump load of woodchips from a dead standing and dry tree, sometime in summer, and store them protected from any rain, out of contact with the ground and with air flow. That is ideal! You definitely want to avoid decomposing chips, those are most best in the garden, big, chunky, dry wood chips are the best.

[@annwithaplan9766]

Good idea. So, the stuff on the inside of the pan never catches on fire? Thanks.

[@edibleacres]

It never fully combusts. It goes through pyrolysis at a nice high, clean temperature and all the gasses that have energy stored in it are burnt in the main fire. We normally get near 100% clean charcoal from this.

[@annwithaplan9766]

@@edibleacres - Interesting. I'll have to remember that for when I get a wood stove of my own. Thanks.

[@Beehashe]

Can you use a small cast iron Dutch oven?

[@edibleacres]

I suppose so, but I haven't tried so I can't say for sure. I would suspect it would hold onto the heat incredibly thoroughly so it would need to be handled and placed very carefully.

[@Beehashe]

@@edibleacres thanks👍

[@danweinshenker]

My experience is that they will soon crack, from the heat stress. Stainless steel hotel food service pans are ideal.

[@Indeewoods]

Nice! Where is your air damper setting on the stove while doing this ? I have a Super 27 as well ( great stove) and wondering if you are dampered right low or med or high while burning these.

[@edibleacres]

When we are running the stove with a charcoal retort in there we like to keep it 'open' to get it up to speed and running strong and then throttle the air intake down so that it doesn't get too hot. CRITICAL that you don't add a ton of wood around the retort at first, have a slightly filled container and a gentle fire and learn before you go full on

[@jim2498]

I would recommend you turn on your backup heat source at least once year. Because it's not good for any system to be off for years and to make sure it works. But I like your video.

[@edibleacres]

Good note, thakn you.

[@kerem7546]

what do you mean by "creating" syngas? Are you just describing a clean combustion?

[@edibleacres]

The wood inside the container is being pyrolysized, as in letting go of all volatile gasses contained. That gas is then hitting the main open flame of the stove and combusting in a super clean way... So it is both of what you are describing if that makes sense.

[@kerem7546]

@@edibleacres woh!!! that is so rad!! glad I asked :)

[@13ccasto]

Hey Sean- thanks for the update on this! How do you know when the pan is "done" in the wood stove?

[@edibleacres]

I mention it briefly in the video, but if I think it's done, I can 'test' by opening the wood stove and using a metal tool to lift the containers lid just a little. If I see ANY smoke or any flame come out I know it still has a way to go. Then I would add a little more wood around it to keep it going. Not super complex and once one gets a feel for it is pretty straightforward.

[@13ccasto]

@@edibleacres Very good to know - thank you!!

Can the biochar uses as charcoal to do the barbecue grill? I am sorry English is not my first language an couldn’t get “ can “ or “ can’t”

[@edibleacres]

Yes, you could make the charcoal with larger chunks and use them as charcoal for a BBQ if that is what you wanted to do.

[@heihei4478]

@@edibleacres Thanks a lot. Great information.😀

[@donatolepore3520]

Charcol also taps carbon until it is burned if left in the soil it is just taking carbon from the atmosphere.

[@Lauradicus]

Hmmm, have you even sketched with it? If so do you have an approximate black rating?

[@edibleacres]

I haven't worked with it much, but it is not 'greasy' at all so whatever that would mean as far as use. If you ran a lower heat fire to make it I bet you could modify the finished char to be more 'crispy/dry' (hotter) or 'greasy' (cooler)...

[@Lauradicus]

[@barrypetejr5655]

Asking because I don't know.....so wood burnt all the way to ash....ash does not have the same effect as the charcoal ?? I know a fine layer of ash is very beneficial to the garden.....

[@edibleacres]

Good question. Ash is nice in small doses in the garden to add minerals and change pH. Well made charcoal doesn't change pH much at all and persists as a super nutrient sponge for 100s if not 1000s of years! Well worth searching about 'biochar' to learn more...

[@johnjoseph7490]

Any reason why you can’t use the charcoal in the wood stove?

[@edibleacres]

You could but it would defeat the purpose.... . The point here is to have a very clean, high value product at the end of the process of heating your home. Biochar is super valuable for the soil.

@@edibleacres Thanks! Just needed a point of reference. Useful to know you can make biochar using an ordinary stove. Liked your tip about using restaurant basins, too.

[@mlindsay527]

I love the simplicity, but how cool would a special made stove be that uses the least amount possible of bio gas to start/maintain the wood gas process, sensors to let you know when it is done and ready for refilling! Design it to hold 8 hours of fuel. Add a bunch of thermal mass and insulation so you don’t have to run it at night.

[@edibleacres]

It would be amazing for sure, but I also deeply deeply appreciate that this solution can be done with more or less any stove and with components that are easy to get and already exist :)

[@monicabooth7358]

If you take it out while it's still hot, don't take the lid off. It will burst into flames.
