- Demonstration on how to make charcoal briquettes, by Amy Smith of D-Lab, MIT (web.mit.edu/d-l.... For more information, please contact charcoal@mit.edu. The charcoal is made from agricultural waste materials using an oil drum. In this case maize stalks were used. The charcoal is compressed to briquettes using a simple hand-operated press. The demonstration was held during the IPIDAT 2009 meeting.

I know that this is an old video, but in my years of searching for ideas on making briquettes this has been by far the best one I have seen. Thank you
2022 and the simplicity of it is still relevant.
Lol I saw this done by village people in east Asia. Here's a professor from MIT to demonstrate... Wow, just how much education has brought us to.
***** bla bla bla indeed, this person thinks she made a invention that changes the world. well she didnt
Love the video and the kind lady in it explaining things in a nice and simple way. Thank you for posting this video. I will try making it at some point.
Making your mold a long tube would require about the same number of hammer strokes as making a single briquette but would yield a briquette bar that could be cut into many briquettes. Another idea would be to make a sheet to the correct thickness, then cut the briquettes out like biscuits.
it is December 12 2019 folks and this is still a good video :) Thumbs Up!!!
Wow. So simplified and effective. You’re a genius ma’am
@Thetruthishere11 The idea is to make use of a material that normally would be wasted and just rot on the field. Wood means trees, and the whole idea is to spare trees.
The casava porrage acts as a binder (glue). I've just been looking at some other ideas and they use clay type soils/water, flour/water, or paper/water mush. Its basically anything starchy or gloopy that will bind it together when dry. The mix tends to be 1/4 to 1/3 binder to charcoal, but thats for experimenting with.The plus sides of burning charcoal to cook on in the home is the lack of fumes and smoke which causes no end of respiratory problems all over the third world. Another plus is it uses what would be waste biomass. Ok, that should be composted and returned to the land but it won't be and it is better than chopping down forest. Yes, "it's bleedin obvious" once you have watched it but the point is she is sharing it. Getting the thought process out there. There are utube examples of womens groups setting up small co'ops and doing this to supplement the family income and cut down on imported fuels/LPG, giving them bussiness skills and developing community. All good in my book.
brilliant work, I live in Africa where his kind of work is very much needed.
We have more advanced machines charcoalmachines.com
As usual, westerners copy what is already done in Africa. Watch this: ua-cam.com/video/wc1gbfyEpOs/v-deo.html
cassiva is a plant commonly grown by subsitance farmers in tropical regions, it's the plant that makes tapioca- so it produces a lot of starch.
Pretty much any starchy binder would work. It just depends on your area. Look for whatever is cheap to make gravy or puddings in your area- cornstarch would work well, anything that makes things thicker or stick together.
Simply beautiful. Excellent works
I live in Mexico and I use leftover tortillas to make porridge for charcoal briquettes, but I boil newspaper in the porridge to make more shock resistant briquettes. If you have clay, then you should use it to make a reusable charcoal mound like Primitive Technology. Btw, I just made a hydraulic briquette press, reducing unnecessary splashing and messy work.
Instead of mixing it with cassava porridge, mix it with the isopropyl- calcium acetate jelly stuff made in Nurdrage's video ( flaming jelly). This will not only act as a binding agent, but will also let you easily light the charcoal briquette on fire without having to dry it out.
Your really a good teacher
Brilliant!!! Far more sustainable for those without infrastructure. Bravo!
Congratulations from Romania! Well done Dr. Smith!
This is fascinating stuff. It's simple yet can be used for economic development in some places. Great video!
Thank you for this beautiful carbonization process revealed!!!
Wonderful work. I want to try this in Haiti especially using the little cube stoves. The briquettes can be dried using the small family-size solar ovens and the big Villager, oven from Sun Ovens International, too. Perfect for small microenterprises involving cooking, bakery goods, soups,...any cooked food without using charcoal from wood. Keep up this work. It is affordable and we intend to try it! WE have 3 Villager Ovens and many small Sun Ovens in Haiti and plan to establish an extension of our bakery program. Exciting.! Will write for drawing and more information for large press to assembly line. Hey...new jobs for the villagers!
Charcoal can be stored for decades, will not rot, lighter by volume than the original material and burns hot. Ideal for small buisness/familys to make charcoal briquettes out of what is considered waste. To cook food even after the stalks would have rotted away, to make money. A large part of humanity cooks their food with wood or charcoal.
This is one of the best way to make biochar of agriculture wastes and its best managment to use in naturaral farming to save our climet and human civilization.
Simplicity = brilliance.
As Einstein said: Make everything as simple as possible, but no simpler.
A few points, Brian. 1. I'm a woman. That might alter your argument. 2. Mental attraction can happen before physical- ever heard of online dating? 3. I see no reason to insult Dr. Smith. Just because she doesn't do it FOR YOU is no reason to be nasty to her. While I think she's hot, you not finding her attractive is no reason to be cruel to ANYONE. Everyone has different things they find appealing- thank God, because that makes the world so much more interesting.
@pilebut The idea is that you use agricultural waste, which otherwise would rot on the field. I agree of course that using trees to make charcoal is one of the main reasons for deforestation.
@UnknownNewDisease cassava porridge is starch paste, potato paste or other starches what we used to used to stick wallpaper with until we refined it and called it cellulose paste same stuff fancy name,when you next cook pasta and are left with slimy water its starch or calories take your pick
Excellent Demonstration 👍
Interesting video.... well demonstrated and explanation on how to...but 1 key item left out was why? why are you making these charcoal briquettes? As a fire starter? Any tinder? I don't understand why you would go through so much hassle.... please explain.
wow im very impressed with what you guys built
I could be rude and say "Google it" but I won´t, but I did so cassava/maniok/arrow root/tapioka is rich in starch, my mother swore by arrowroot as thickening for clear sauces and for fruitdishes like Danish Rødgrød or Russian Kissel or Compote or Chinese food. In Sweden we make "kräm"and "saftkräm", Rheubarb is popular in summer, eat it with milk, it´s tasty and neutralize the otherwise strong acid in rheubarb which could be bad for your teeth."Rabarberkräm". PS Lignin ought to work.
she should get a Nobel prize.because what she does can safe, at first millions of cm3 of wood that will be chopped down to make cooking fires... and make life easier for millions of people BUT also give work to people who will make these brickets.excellent done Doktor!
-keep it simple stupid- ( no offence to the Doctor) indeed works and works well!!!!
Only this is nothing new. People have been making charcoal for thousands of years my friend. This professor is just so pleased with herself for having stumbled on a skill that uneducated peasants perfected and use on a regular basis. She acts like she invented the wheel.
austrorus noobelprice!??! whattt??? NO way!! this is just some old bullshit. if this is worthy of getting a nobelprice I should have got 10 by now.
Nice vid Amy. I have been experimenting with making charcoal for my smoker and was having a hard time figuring out "when" to seal it up, good information. Thanks :)
I just did a charcoal training last week, after many years away from the project, it was great. And what I found is that people tend to want to cover the drum too soon. Patience!! It is better to have a slightly lower yield, with everything carbonized than to have incomplete carbonization, which leads to lower quality briquettes, and more difficult handling of the material...
@Thetruthishere11 I agree that something like a rocket stove would also work. However:
1) they are much larger / more complicated / more expensive than most regular cooking stoves that people have, which are basically small improvements over an open fire
2) making the charcoal briquettes in the field reduces the volume to be transported and adds value, which can help build small enterprises
3) making the charcoal in the field gets rid of polluting substances away from where people live.
2)
You do this on a beach???
that professor is so knowledgeable and informative
Beige Velivo shes the kind of person who's not smart enough to do the real stuff, she takes credit from other peoples inventions who invented this decades ago. those inventers moved on and are building rockets by now. shes 50 and still has nothing better to tell than this.
Being fairly academical myself, and coming from a family who have all a high level of academics, i can wholeheartedly agree with that!
that's very interesting, thanks for the suggestion! I didn't know it, and will pass it on also to Amy Smith of MIT.
Not sure if you are interested but when you sho the square stock, instead of welding the bars on the bottom just leave open and use a slightly thicker base, that way the outside just sits over the base and no welding other than for the tamper. Neat ideas though.
I enjoyed watching the video clip.
Thank you for sharing.
God bless.
Yea, we need more info on alternative binders.
This is both science and art...science is precise ..and art allows for environmental variables ...tis is a great way for people living in underdeveloped nations to be self sufficient. And juat because in USA we have modern convenience's doest make it best...independence is best!
good technology that is sustainable to small holders' farmers.
Someone mentioned using a large pan instead to make multiple bricks. That would work, & the top to the pan can be made to press & cut the bricketts at the same time!
that was amazing ! best thing ive seen for a good while.well impressed thanx
Thank you so much dear muzungu.
Super leuke video. Wat doen jullie mooie projecten. Inspirerende!
Leuk he om videos te maken. Vind ik zelf ook altijd mega gaaf om te doen.
Heel veel succes met alle komende video's!!
Amazing video and so simple. Looks like fun to.
4:50 when you see wood turn red glowing eye ball it with a bigest stick and flames get smaller they turn glowin red if you put the lead turn black if you keep it glowing turn to white ashes
"It's remarkable how common sense comes from the field, not from academia." Aint that the truth!
And that was from a professor.
Cassava is a starchy crop. When you grate it, it becomes a sticky mass, that is a quite efficient glue.
A little confused about how is closing the bottom and covering the top does not smother out the fire inside the drum. Does the drum have other holes that are left open so air can get in and continue the burning process?
Italians in the southern mountain regions have been making charcoal this way for centuries! Until 1862, Italy was no more than a collection of City-State Plantations owned by whom ever was in favor of the Vatican. Countries from all over the Med. had their hands in these provinces, one of the reasons why regional cooking differences so greatly in Italy today.
Yeah i got you...Cassava porridge..searching and patience makes you success..problem solve..good idea for business too...thank you
In making charcoal there is actually supposed to be as little air flow as possible.
I wish I were able to make charcoal that way in my backyard without my neighbors freaking out.
@realjoefriday thanks for the suggestion!
Nice demo, thanks
Amazing I'will try it.
this video is amazing. makes me wanna make my own charcoal
Bridges are not only cassava, but also seaweed and maize are okay.
nice video, thanks for sharing. Wouldn't you rather design your bricket form to have facets like the charcoal you buy for bbq because of the radiant properties?
Thank you
thank you I`ll try it soon
TLUD design by the looks of it.
Works best when lit from the top.
Very helpful, thanks! :D
would be grateful if someone could share research papers on the methodology please
lost me at the binder, what is cassava porridge, and/or what would be an easy alternative?
Thanks so much
in that case, just use dirt to plug up the holes. in my opinion, there's no reason the elevate the barrel at all, no point in risking the barrel toppling over in the middle of a burn. just make a base from dirt or sand and make the depression and air channel and fill the channel when the smoke changes. you can also replace the air channel with a steel pipe, a 90 degree bend and a cap, having the bend under the barrel and having the opposite end ready to take the cap.
@lucasmorter you are right of course that fields need nutrients and fiber to stay healthy. you could also use manure or fertilizer to accomplish this, or leave the land lay fallow one year in three or four. Another option is to use the plant matter to make briquettes, and return the ash to the soil. Most of the nutrients are in the ash. In any case, mother nature probably didn't intent to have large fields with a single crop :-)
can probalby curve a water pipe around that barrel a few times to heat up some water for a hot shower.
@ 8:25, do you even need the bar stock across the bottom? Just a short section of square tube, the back plate on its post, and the presser plate with the whacking end.
Having the bar stock across the end means being able to scoop and fill more easily, but it isn't crucial. And if the users don't have access to welding, cut the square tube with a hacksaw but leave a couple of flaps to fold over. Those become the back.
I tried making charcoal briquettes using rice straw but it doesn’t burn well. It dies off before burning completely. I made it with carbonized woods and it works perfectly. Do you think the problem is with the rice straws?
@lucasmorter Although wood is a great fuel, the trouble is that in many of these countries extensive deforestation has happened, and therefore firewood is not readily available. In Nepal, woman already spend 3 hours a day on average collecting firewood.
I have a burn setup that diverts waste gases to the fire, thus reducing the fuel I need to char a barrel of wood.
BUT CAN SOMEONE TELL ME OF A COMMON BINDER I CAN USE TO MAKE BRIQUETTS? I live in BC and don't have cassavas.
Cassava plant is a root vegetable. Looking at the paste that she had in the video, I am going to take a guess that it's just intended as a binder for the carbon. So maybe shredded paper and water soaked for a long time in high concentration to make a porridge may achieve the same thing? Paper and water are the two of three ingredient in other biomass briquette so it might work here as well? You probably just won't end up with charcoal per se but biomass briquettes. Would love to try this.
facinating
I love this, simple and accessible. The one question I have is the binding agent, what kind of proportions do you use or is it just a case of trial and error?
what is the ratio and proportion of the burnt material: cassava porridge? is it 1:1 ?thanks.
neat, but seems to be a lot of work for 12 brinks a minute...couln't you make a whole pan (say 12"x12") and then cut is with a large makeshift knife?
I want to make my own square shaped briquette press which is medium sized; this is therefore, I earnestly request you to send me the dimensions of the briquette mold and the other required dimensions of the briquette press.
Have you tried the press without a bottom plate - just against the wood block?
Does anyone here know about TERRA PRETA?? These briquettes look perfect for spreading over fields, they will break down really well!!
@feltwiener69 Any kind of starchy material usually works, at least, if you can 'bake' the brickets afterwards to firm them up. Otherwise, you will need some kind of natural glue, I suppose.
Compared to Kingsford they won't compare Since Kingsford uses hardwoods and chemicals to make the briquettes last longer and burn hotter. This process though sounds great it uses up a lot of waste to make something more useful.
it's a lot easier to just make a depression or hole under the barrel and make a air channel than using rocks to elevate it. with the rocks you need to kick them out without toppling the barrel and you need to handle the barrel to prevent it from toppling over, with a depression under the barrel with a air channel, you just need to seal the top and throw a couple shovel fulls of sand into the air channel and it snuffs it out.
Great video! I like the dog in the background. I am testing your application using my Weber BBQ and OAK flooring from a house next door. The wax and paint on the OAK act as an accelerater. I have not go the timing right yet. This wood is about 5/8" x 3" x 6". Do you have anythoughs?
Can we use normal glue, such as white glue instead of the 'casava porige'?
Thanks for this video Amy... I could certainly apply some if not all the information you provided in here to teach my people back home.... would you be so kind to post a video of the "production line" which you mentioned towards the end of your video. thank you for sharing your ideas.
Amazing!
Yea its the way to go
In Manila, one guy was selling "green charcoal " which is ver similar to this. However people say that the charcoal doesnt produce smoke if used. Can you give us the "recipe?"
Thanks for this! I'm wondering how this could be applied to a diy incinerator toilet build. I am looking for a low-tech solution to expensive commercial incinerator toilets for a shipping container house project for people in need.
How musk is made and how to combine cassava porrage
Estimada Dama , podria explicarlo en español .. o indicarme con que mezclo el carbon antes de prensarlo ?
Dear Lady, could explain or point me in Spanish .. I mix with charcoal before pressing it?
@lucasmorter was this intended humourously? this obviously is not intended for use in western countries, but for developing countries, where you can't buy 'kingsford'.
Похоже что есть проблемма по приобретению каменного угля, впрочем мне так нужен этот материал что слов нет. Теперь здесь выражаю всем вам благодарность за показ способа создания активированного угля из древесины в закрытой системе. Правда немецкого языка не усвоил но видео помогло.
Very, very intersting!!!
could these charcoal briquettes be used to filter water through?
Thats a great Idea,... and save.
But either way I would mould me a forge, so I can make the design as ergonomic and save as possible for plenty of differant settups.
Greets
so I guess they have arc welders in these countries to weld tabs on ram blocks and post charcoal is a great way of storing seasonal energy or compost the smoke produce is what we don't see its done by some one else miles away so it we don't see it ,this coal made from waste not from mining , like no pollution from mining.
Good job
The good thing about this is if you bury more of the briquettes than you burn, you have a carbon neutral source.
