    Wunderbar! Thank you so much for this list. This is the most sensible approach to Biochar deployment. I would like to add one use … Food preservation. I put a mesh bag filled with Biochar pieces in the refrigerator to absorb odors and ethylene gas that fruits and vegetables emit. Ethylene gas will make produce ripen and rot faster so sorbing it keeps the veggies fresh. There is great potential to use this commercially as food spoilage and waste is a huge issue. It is a natural benefit of using Biochar in soil as root crops like carrots and beets are often stored best unwashed. Biochar in soil that adheres to these veggies will help keep them fresh.

    Vielen Dank,

    Thanks Kelpie, that’s a great use of biochar and I will add it to the list with your explanation. We use biochar since long in the fridge against odours and never thought even about this principle that works behind keeping the food longer fresh. I will try it in the bread box too. And I am just thinking of storing apples, carrots and even tomatoes in a bed of biochar. Will try it. Thanks again and also for your great work on biochar and your website: http://www.greenyourhead.com.

    Hello Folks

    This is a good run-down. My only issue is that charcoal used for any application outside of agriculture should not be referred to as biochar. The English language already had words for carbonised material, so using the word biochar for non-agricultural applications confuses the fact that biochar is a charcoal specifically intended for agriculture, not industry. The word biochar should not be used as a catch-all word for any carbonised biomass.

    Charcoal = The catch all word for carbonised biomass. Covers a very wide range of qualities. May used as a fuel, for making activated carbon, as biochar (when prepared properly), or any one of 8000 different uses.

    Biochar = A form of charcoal specially prepared to be “fed” to plants or animals. You should not feed just any grade of charcoal to plants and animals .. if you do not want to make them sick. My personal test of a fresh biochar (with the exception of those made from manures) is that I should be able to put it in my mouth and chew on it. If I can’t do that then it is probably not suitable for plants or animals without additional processing.

    Activated carbon = Carbonised material, which might be from biomass, coal or petrochemcials, which has been prepared with a high surface area (typically more than 400 m2/gram). Sometimes acgivated carbon is used in agriculture, but most of the time it is used in industrial and household applications as an adsorbent. Some biochars have properties similar to a low grade activated carbon, however they should not be called biochar when used for industrial applications.

    Keep up the Great work : ) and than kyou Kelpie for more great ideas : )

    Hi Dolph,
    You are quite right to insist on the meaning of biochar. The problem arises as the article is a translation from German where we use the term « Pflanzenkohle » which means vegetal carbon. In German this is clearly distinguished to Holzkohle (charcoal). For the most of the 55 uses the same quality exigencies that you described for agronomic uses apply (chewing on it with no harm or the EBC-certificat). The whole thing about the 55 uses is that on their dead end they finish charged and enhanced in the soil. The end of fate of all this uses is a soil amendment which is for free as it was paid by all the preceding uses in the biochar cascade.
    Thanks Dolph, as an admirer of your work, I am happy to have you commenting in Ithaka

    Awesome Hans, thank you for that it makes it crystal clear now : )
    I did not even think about translation problems.

    Your entire site is really well done.

    The ultimate value of biochar is in the realization of a complex network of causes and effects in the development and management of sustainable city-regions. This has been the subject of our research for more than thirty years. (For more on this see: « The City as Fulcrum of Global Sustainability, » Ernest J. Yanarella & Richard S. Levine, Anthem Press (UK),2011.) The sustainable city will be powered by renewables – principally solar energy and wind, however these are intermittent sources and it is difficult to store the energy they produce. Pyrolysis of biological materials has two fractions: the gases driven off in the heating process – principally carbon monoxide and hydrogen, and the char, which is left behind. the process may be driven in two different ways: the gases – also called producer gas, which can be stored and which can be substituted for natural gas, may be burned to produce the bio-char, or the biochar can be used as the fuel to pyrolyze the producer gas, or the same process can be used to produce a combination of producer gas and char. At the moment the emphasis is mostly on the production of bio-char using the producer gas fraction to do so. In the current economic situation this doesn’t appear to be very attractive although when long term considerations are taken into account, particulerly the alieviation of global warming through carbon sequestration, the economics couldn’t be better.

    To see how attractive a pyrolysis based local economy will be try this thought experiment: Imagine a small town-region where both agriculture and forestry and value-added industries derived from them are being practiced all centered around a small, but dense urban core. The buildings in this community are all built to the Passivhaus standard greatly reducing their use energy. Production from the land produces a good deal of cellulostic residue and along with human and animal wastes becomes fuel for a pyrolysis process. Wind and photovoltaic collectors provide the great majority of the electricity needed in the town, but as these renewable sources of energy are intermittent (no sun at night and on cloudy days) another source of renewable, but storable energy is required. The pyrolysis process is used to build up a store of producer gas which is used to power a standing engine coupled to a generator to produce all the required electricity when wind energy or solar energy (nights and cloudy days) is not available. When a sufficient store of producer gas has been produced, the pyrolysis process reverses its output to produce bio-char for all its many uses. The waste heat from the pyrolysis process is used to power any industries that are able to use it as well as a district heating system to provide most of the heat necessary to heat the (now reduced energy requirements through the use of the passivhaus standard) homes, factories and other buildings in the town. The town -region is a zero energy, zero unemployment economic ecology as the energy-employment couple becomes self adjusting to accommodate ongoing conditions. The town-region system satisfies the requirements of sustainability as it has the capacity of being the sort of no-growth, balance-seeking, self-provisioning (on a net basis) system that both Ecological Economists and Sustainable City theorists advocate. It also describes a system which is designed for continuous improvement (increasing the bio-char quotient of the soil for one thing), and toward the enrichment of an empowering participatory negotiation process as surpluses continue to accumulate. This is a short sketch of the ultimate value and use of bio-char/pyrolysis processes (for more detail, including the Sustainable Area Budget, see the book or http://www.centerforsustinablecities.com).

    This compendium is really excellent. Thanks for all the thought and work. I will refer people to it.

    I have a question that may be important, based on a report I can no longer find on your site about the results—bad—when you gave urban « hobby gardeners » some char to use. As I remember it, you were puzzled, because the avid urban gardeners who had sought you out in previous years, agitating for char, had in general had EXCELLENT results. You were expecting the same from the hobby gardeners, but even after you supplied them with good live compost (in case that was the problem), their results were ragged. A few had a good increase in yield, but most? many? actually got worse.

    So I wonder… could the hobby gardeners have been using city water, full of chlorine? Most people do, after all, and think nothing of it. It’s what everyone does—water with the water you have. Of course. And if you’re using NPK fertilizers, all might seem to be well. Avid long-time gardeners, on the other hand, would probably have rain barrels, having had an experience like mine described on my website (below), when I finally figured out that city water kills microbes, all right, not only the ones that might make me sick, but the ones that my plants might need.


    This idea makes sense to me because it also makes sense of the works-in-the-tropics factor: those tropical fields are not urban, and the water isn’t treated.

    If this is true, harvesting enough rainwater to fill cities with backyard forest gardens won’t be easy, but at least we’ll know our struggle is not the fault of the char.

    The article you were looking for is here: http://www.ithaka-journal.net/pflanzenkohle-in-kleingarten-resultate-2011?lang=en. Results of biochar have been not too bad with an average increase of more than 10%. However, you are right that chlorine treated water is not beneficial for soil microbes.

    Titre: city water

    Great article. A friend and I were just investigating production of charcoal and there are a lot of ideas for markets we have not thought about.

    As to the problem with city water, the solution is right here in the article – no. 27/28. I also suspect that if chlorine is the culprit, that standing the water for a while before using it to water the plants might help to evaporate the chlorine.

    By the way, I have had amzing results from taking charcoal for a bad belly (cramps, and also nausea). I have used charcoal from my fireplace, but chewing the stuff is not a nice experience. After discovering that you can buy tablets of activated charcoal, I use that instead. Still, the plain old lumps do the trick.

    One other use of charcoal I read about is for lightening up your teeth if they are stained from tobacco, tea or coffee. You grind up charcoal to a powder (those tablets are probably best) and apply it to your teeth, wait for 5 minutes or so and rinse well. If your teeth are naturally dark, it won’t work. Sadly, dark teeth can be a side effect of certain antibiotics taken in childhood. That was particularly prevelant in the 60s for any minor illness.

    Dear Sir,
    I have published a book with Amazon in July 2016 under the title:
    « Nano-Biochar Biochar Charcoal & Coal Based Biochar Design of Pyrolysis Reactors Production Methods & Applications: Strawberry Production in Soilless Culture Using Nano-biochar »
    Part of this book is general information and another parts is about our 10 years experiment with Nano carbon.
    I will be very glad that you inform your membership.
    Thanks and best regards

    Mr. Levine, with your 30 years of experience could you explain how to store production gas? Biochar is new to almost all of us. With any new industry there is a learning curve; for both the manufacturers and consumers. Not all biochar is the same; this is probably why there are occasionally poor results. Char produced at high temperatures will have high pH; as high as 11. This obviously is not good for most soils. Using biochar on very poor soils can have an initial effect on plants; but they usually rebound and outperform the non treated plants. The biochar will absorb the nutrients first before making available to the plant. The tests that have really hit home for me is the improved Cation Exchange Capacity; enabling plants to absorb more nutrients; resulting in bigger stronger more healthy plants that produce more. This has also been proven in livestock.

    In order for biochar to protect against electromagnetic radiation,
    must it be inoculated with microbes or, can it be raw carbon?

    Same question concerning it’s thermal insulative/humidity property.

  15. hps

    the electromagnetic shielding should be independent of microbial interactions as it is a rather physical effect of the biochar quality. Same for insulation and humidty dynamics. However, microbes may to a certain extend effect these properties though rather indirect than direct (means the microbes do not effect these properties itself but their activity might affect the physico-chemical properties of the char… very speculative though)

    Hi there! my daughter is doing a science fair project on Biochar. She is testing 3 different feedstocks to make biochar. We need to make a DIY Kiln. She is having difficulty finding enough research for making a hypothesis. She is making her own Biochar from wood, cornstalks , and grass clippings. She is measuring which biochar will absorb the most nitrates. Can you give any advice? On reasons why she should select one over the other?

  17. hps

    Hi Michelle,
    Please check our article about Kon-Tiki kilns which are the easiest way to make biochar: https://www.biochar-journal.org/en/ct/39 and here http://www.ithaka-institut.org/en/ct/111-Dig-your-own-soil-Kon-Tiki–
    In regard to Nitrate adsorption, differences between feedstocks are minor compared to pyrolysis temperature and post pyrolysis treatment like water vapor impregnation. There are some interesting scientific paper about the subject, some of them you can download here: http://www.ithaka-institut.org/en/publications

    Titre: Biochar on cosmetics and biological filtration

    Hello there,
    It’s an amazing and hugely explanatory article you have there. We are farm that practices natural building, regenerative farming, natural cosmetics, low-technologies etc. Among that we make our own natural cosmetics, we use Reed beds to purify our gray water, we use biodigester toilets and compost ones. Actually the uses biochar could have in our community are inumerous. We are already producing biochar with pyrolysis in a diy system with barrels.
    I was wondering for two things I cannot find online.
    Do we have to activate the char for using it in soaps and toothpastes, and if so with which process and materials?
    After using it in our Reed bed system to purify grey waters (coming from only natural soaps) I guess it is not appropriate for using it in the soil. (As it might contain salts in high quantities). Is this valid, and if so what would you propose for an after use of this biochar?
    Thanks a lot,

  19. hps

    Hi Christos,
    No need to activate the biochar to use it for soaps etc.
    Normally, the biochar from your grey water system should not do any harm to soil and plants. You can try it on a small plot with various plants. If they grow better, you can extend the application.
    Kind regards, hans-peter
