AllTrials Campaign for Biochar

AllTrialsBen Goldacre, a UK physician, writer and bad science debunker, has helped found an excellent initiative called the AllTrials Campaign. The aim of the campaign is to correct many of the funding inefficiencies as well as much of the mis-(or dis-)information related to drug trial data around the globe. I think the world of biochar could use something similar. The basic ideas behind the AllTrials Campaign that could benefit the biochar world include:

  1. Pre-Trial Registration – one of the shady elements of drug trials is that apparently the methods or measurements get shifted around during the trial to better highlight the positive aspects and/or conceal the less attractive outcomes. Pre-registration of the trial and methods precludes this type of shenanigans.
  2. Demonstration project funding necessitates trial registration – any funding for trials provided by government, NGOs, commercial enterprises or academia, etc. would require registration of the trial and reporting of the results.
  3. Negative findings more likely to be published. Biochar can help in many different scenarios but not all. Publishing ALL findings, including those that don’t have great results, will help understand which biochars work best in given situations.
  4. Reduced Conflict of interest. Biochar production companies may have a conflict of interest in terms of not disclosing less than positive results.
  5. Facilitation of follow up.  As researchers must list their contact details, others are able to follow up more easily to ask for further information.

Providing a basic template for information to be collected for trials such as biochar production parameters (i.e. technology, highest heat, hang time) plus pre and post treatment of biochar, application methods, amounts, depth, etc. would be very beneficial to facilitate apples to apples comparisons as well as replication of best practices.

So biochar industry, what say you?  Shall we join the transparency revolution?

 

 

Could the next biochar frontier be ‘Sea-questration’?

reef balls

Taking up reef ball residence source: The economist

Sadly it’s been a long while since I read The Economist but I was unable to resist this week’s cover on the battle of the junkyard dogs (aka oil sheikhs vs fracksters). My m.o. when reading this particular magazine is to quickly scan the whole thing and see what grabs my attention first, read that, then read the entire (OK most of it) thing later. A picture labeled ‘Taking up reef ball residence’ was the first prize winner and was soon devoured by my eager eyes.

The reason this perked my interest is that I have long thought that artificial reefs made out of biochar plaster might be a very interesting area of research. It might just prove to be the next frontier in multi-beneficial carbon ‘sea-questration’! There were a few particularly relevant things I learned from the article. First concrete seems to be the material of choice for reef balls but they need to be treated to reduce acidity. Also when casting the balls in fiberglass molds, they are sprayed to promote the creation of tiny hollows to promote coral growth. Enter the biochar alternative. Biochar is usually alkaline so no treatment required. Also concrete carries with it a very heavy carbon footprint, whereas biochar could safely bury carbon in a beneficial manner. And as readers of this blog will know, tiny holes are what define biochar, so I would think that coral would glom on to it in a big way.

The other fascinating bit of serendipity is that Thomas Goreau, head of the Global Coral Reef Alliance who is heavily quoted in the article, presented at the 2013 NA Biochar conference last year. His topic was on something completely different than reef-covery operations, but it was encouraging to think about the possibilities of connecting the carbon dots and potentially testing some biochar reef balls in the not too distant future!

So for those of you that would like to offset your carbon footprint in the most memorable and beneficial way possible, perhaps you could sponsor a biochar reef ball for your favorite (but ailing) dive spot or mangrove.  These new biochar reefs, perhaps we should call them ‘sea-mentaries’, might just be able to help bring back dead zones!

Biochar: Enabling the ‘F’ word

Fracking

Not all uses of biochar are as righteous as others…

No not that ‘F’ word. I’m talking about Fracking. Recently yet another person I really respect in the biochar world has been talking about optimizing biochar to mitigate the harm created by fracking. This is one of those uses of biochar that makes the idealist in me cringe, but the pragmatist in me understand that fracking is happening at an ever increasing rate and the environment surrounding fracking wells is suffering. Badly.

Articles such as this one, which talks about using biochar to treat the enormous amounts of flowback water contaminated during fracking show there is a lot of ‘promise’, if that is the right word, in using biochar to filter out these unnamed toxins. What they fail to address though is what to do with that biochar once it has adsorbed the toxins. It’s not exactly a desirable commodity that could be sold. Perhaps the chemical filled char could be cleaned similar to how activated charcoal is, but that is both costly and complicated and most assuredly would negate any potential carbon negative aspects of using biochar. Perhaps it could be injected down old oil wells or old mines where it is unlikely to come into contact with food growing land or ground water. But in all likelihood it is likely to be managed as hazardous material, which just means one more headache to be solved in the fracking formula. This just kicks the can down the road a bit longer.

While the market for biochar is still at the neophyte stage and production has, for now, outpaced demand, I suspect that more and more biochar will find its way to uses such as this one. We shall, or I suppose I should say we ‘shale’ see what the future brings.

Giving Thanks to Biochar’s Sherpas, Shamans & Scientists

Thanks

A charred turkey homage to biochar’s sherpas, shamans & scientists.

When the biochar industry does finally take off, it will be in no small part due to biochar’s Sherpas, Shamans and Scientists. The Sherpas include not only those with enough foresight and fortitude (not to mention cash) to invest in the early life cycle of biochar production, but also those willing to endlessly carry the biochar flag hither and yon. The Shamons include a select few individuals that somehow seem to be uncommonly tapped into nature’s mysteries and intuitively understand how biochar best interacts with it. The Scientists include an increasing number of researchers from an ever expanding set of academic disciplines. No longer just basic and applied agronomy, academics involved in engineering, waste management, renewable energies and more are focusing on biochar and the number of peer reviewed articles has been increasing exponentially which is exciting and daunting all at the same time.

Though these three disparate groups of biochar supporters rarely get together to break bread, eat turkey or talk biochar around the same table, conference or even on the same social media forum, I’m still thankful to know many different individuals in each camp. They each have their own perspective and role to play in launching the biochar soil’ution.

Hey Preppers meet your new best friend: Biochar

Here's why biochar just might be the most important par.t of a Survivor's Toolkit

Here’s why biochar just might be the most important par.t of a Survivor’s Toolkit

Attention all Preppers: what single item is the most valuable and versatile in a survival kit? Allow me to make the case for an item that can be made by just about anyone, anywhere: biochar (or charcoal). I am far from what you’d call a Prepper but I recently attended one of NY State’s Preparedness Training classes which got me thinking of the various ways that biochar could be of value to individuals after an emergency. Here is my top 10 list of reasons why biochar ought to be on every Preppers ‘Must Have’ list:

  1. Water Filtration – while not as high tech as some of the gadgets out there, biochar can do a pretty good job of getting toxins out of water. (If you’ve got kids and want to show them how it works, put some food coloring in a glass of water and then add a chuck of charcoal to it. By the next day the water should be clear.)
  2. First Aid – Charcoal has long been used as a means of riding the body of toxins when ingested but can also help on things like bee stings and poison ivy when used in a salve.
  3. Sanitation – let’s face it, toilets when you are roughing it can be kinda gross. Put your biochar to work and you can not only clean it up but you are making a nice fertilizer while doing so. You could even use if for kitty litter!
  4. Extended Food Storage – have some fruits and veggies that you’d like to last a bit longer? Bury them in biochar to keep them from spoiling.
  5. Fire Starter – (this is where the real difference between biochar and charcoal comes in) – this will hopefully not come as a shock to anyone, but charcoal catches fire pretty easily so you can always use it to get your fire on.
  6. Cooking Fuel – not only can you start a fire with charcoal, you could use it for the fuel to cook with if you can’t find any other dry stuff to burn.
  7. Deodorizer – Survival situations sometimes involve some stink, like if the sewage systems overflow like they did during Sandy and Irene. Use some biochar to help get rid of the smell and some of the humidity too.
  8. Cosmetics – biochar can be made in to soap, exfolient, tooth paste, heck I have even used it as a mouth waste to get rid of mouth bacteria.  And for those of you that want to  glam it up, there is always the eye liner usage.
  9. Emergency Writing tool – Once the ink runs out of your fancy pen, grab a hunk of char to jot down your inner most thoughts, or at least use it for emergency communications as I did in my fancy sign above.  (Warning it is messy and will not stand up to rain.)
  10. Perhaps best of all it’s FREE and you can make it yourself. What’s not to like about that! If you do it with the right gear (as I talked about here) you can even generate enough electricity to charge your cell phone, a fan, or a radio while you are making more biochar!

 

 

Sparking a Fire

Sparking a fire

In math the inflection point is the point on a curve where the sign of the curve changes. In business the strategic inflection point is when massive change occurs or as Andy Grove, Intel’s co-founder has said, it is “an event that changes the way we think and act”. It could be positive and lead to that dreamed of rocket ride to success or it could just as easily be negative leading to a company’s demise.

When I first learned about biochar, I was convinced that its ability to sequester carbon was going to be what caused people to sit up and take notice of biochar in droves. That hasn’t happened yet for a lot of different reasons. As I became entrenched in the biochar industry I became convinced that its ability to improve yield and soil fertility was really what was going to cause people to sit up and take notice of biochar in droves. That hasn’t happened yet either for a lot of different reasons. Both of those might still be inflection point triggers for biochar if regulatory changes occur in carbon markets or if food security continues to be challenged by climate change and low soil fertility.

But recently I’ve begun to see that there might actually be other triggers which had never occurred to me until I began doing some investigative reporting for a few upcoming articles for the Biochar Journal. Lately I have been talking to people that live in far flung places in Asia and Latin America where agricultural practices are very, very different from the norm in my neck of the woods. What I’ve started to see is that pollution may be a critical trigger, and not that gaseous pollution that is causing climate change either. I’m talking basic air and water pollution.

Burning crop residues is something rarely seen in Western New York but it is apparently very common elsewhere in the US as well as in many other parts of the world. Particulate emissions from burning causes horrendous air pollution which has a significant impact on human health – not to mention the complete waste of nutrients! To allow locals to breathe easier, regulations are beginning to be drafted and enforced to prevent the burning of crop residues which means farmers will need alternative ways to manage them. Charring these wastes in the right type of pyrolysis or gasification equipment will not only mean reduced pollution, but it can also mean renewable energy and of course biochar.

In other pollution news, dumping crop residues is the guilty party behind massive water pollution. Since clean water is becoming scarce and increasingly expensive, more attention is being focused on reducing point source pollution. Here again biochar could play an important role in averting pollution, generating renewable distributed energy and of course biochar.

Sometimes it only takes one spark to light a fire, but I am beginning to realize that that spark may be caused by different particles when it comes to biochar!

Upcycling Halloween

pumkins & biochar

Fall is a gorgeous time of year in the Finger Lakes. One of the prettiest things to see, besides the stunning fall foliage, is the site of so many pumpkin patches dotting the landscape. Generally one of the top five producers of pumpkins in the US, New York harvests roughly 50,000 tons of mostly ornamental pumpkins from 7,000 acres which nets farmers a chilling $25M. On a micro scale that translates to: ~7 t/acre at $500/t or $3,500/t per acre.  Not a bad revenue per acre for an annual crop! On a macro scale, Americans grow 1.5 BILLION pounds of pumpkins per year.

Rarely have I given much thought to the afterlife of pumpkins but now that I’ve become such a waste hunter, I always seem to be pondering what heaven looks like for various types of biomass. For pumpkins it seems that come All Souls Day, the fate for most of those lovingly carved globes is a rather unglamorous trip to the local landfill.   Yep, that’s right. Unlike their tasty cousins grown in Illinois which are destined for pumpkin pies, the ornamentals get chucked in the dump where they turn into something far scarier…methane! If you bury pumpkins and starve them of oxygen, their gaseous ghosts will continue to haunt us all long past their prime.

Although there are ways to delay the trek to the dump what I wanted to know is this: could all that pumpkin waste be used as a feedstock for biochar? Given that the moisture content of pumpkin guts (ok if you want to get technical, the shell, pulp or fibrous strands) is really high (probably ~90%), that part of the pumpkin is, unfortunately, not really a likely target for biochar unless you dehydrate it, which is normally a fairly energy intensive process. But hey, maybe California could collect and ‘squash’ all those discarded pumpkins to recycle all that water for irrigation! With 1.5 Billion pounds * 90% water we are talking a LOT of water!!

Not one to give up on any biomass as a biochar prospect, I came across some articles that claim that the stems or seeds of pumpkins have been turned into activated carbon which is useful as an absorbent for toxins. This of course leads me to think that biochar made from certain pumpkin parts might not be a bad idea. But really who is going to go out separating all those stems from all those pumpkins? Perhaps this is a job for the headless horseman but not for me!

As I was trying to think up a ‘Boo-char’ experiment for this year, I settled on this: why not fill up a pumpkin that has had its innards outed (so I can toast the seeds and maybe, just maybe, char a few) with biochar and see what happens over the winter to the char-filled pumpkin. Maybe it will act as a desiccant and dry it out. Maybe it will prevent it from molding. Or maybe it will turn it into black cauldron!  We shall see..

Reimagining PlastiCulture

Reimagining Plasticulture

Some words should just never have been invented. Plasticulture is one of those kinds of words. Apparently someone felt the need to put a name to all this plastic that is now covering soils, crops, trees, greenhouses, etc. and thus the word plasticulture was born. While it’s supposedly a word smush of plastic + agriculture, that is not the first thing that comes to mind. It sounds more like ‘plastic culture’. Culture has many different definitions, one of which relates to excellence in some area (arts, manners, etc.).   Perhaps some think we’ve reached plastic nirvana but I definitely don’t count myself among them. Another meaning of culture is a ‘stage of civilization’. Sadly this one seems to make more sense. We certainly seem like we have reach a point in time where plastic is the answer to nearly everything. Plastics in agriculture was invented to solve certain problems (i.e. weed control, improved water management, prolonged shelf life, etc) yet it has introduced a whole host of new problems.

While creating a certain dependency on finite fossil fuel based materials  is perhaps a tad short sighted, that is not the worst part of getting farmers hooked on plastics. The ‘assembly-line’ mentality behind the product is much more detrimental. By that I mean, once the product leaves the factory, it enters the land of ‘not my problem anymore’ (can we get some extended producer responsibility on this subject please?). Farmers use the plastic for a growing season or a winter to wrap their rolled bales of hay into giant marshmallows or cover their silage, strawberries or greenhouse or all sorts of other uses. After that is enters the land of ‘hmmm… what do I do with this mountain of plastic’. Burial or burning seem to be the most common solutions; yet one is not good for the land, the other horrendous for the air.

What if we were to reimagine the whole notion of plasticulture and displace plastic with, say, I don’t know, maybe biochar and move towards Charculture, perhaps? Before any eye rolling, let me assure you that it isn’t really that far out of a notion. Fabric made from activated carbon (AC) already exists. It’s not nearly as cheap as plastic but perhaps swapping biochar for the more expensive AC will help reduce the cost. Color-wise char fabric would be fine as a lot of plastic couture is already black. Functionally it should be able to block weeds, help retain moisture and perhaps aid in fermentation as plastic does. But the real triumph would be that the notion of disposal, especially disposals with detrimental effect, would all but disappear. Char fabric could be used for all sorts of secondary purposes once its first life is over; from enriching the soil, to building buffer zones around water bodies, to filtering waste water, not to mention all that sequestration potential…

Preaching beyond the Biochar Choir

What is Biochar

Much as I like attending biochar related conferences to keep up-to-date on what is going on in the industry, I also like attending meetings with a broader sustainability orientation. Not too surprisingly few of the broader context conferences have biochar on the agenda. Such was the case for the NYS Conference on the Environment held last week in Binghamton, until, that is, I contacted the organizers and (rather brazenly) asked at the 11th hour if they might have any speaker cancellations and need someone to fill in. Serendipitously they did so off I went to preach the gospel of biochar to an all new audience.

I arrived just in time to hear them mention the word biochar in the first General Session. Minutes later a brave woman in the audience raised her hand to ask “What is bio-char?” in that tone one often hears when one is trying out a whole new word and can’t quite figure out where to put the accent. I smiled, waiting to hear the response. The Climate Change panel organizer, a Climate Change Analyst from the NY DEC, gave an answer that made me really happy I pushed to get on the agenda. He said something to the effect that biochar seemed to be a very promising technology but that it hasn’t yet realized the potential that some have claimed it has, and that he was really looking forward to learning more about it. Then he said he sure hoped the presenter was in the audience and could shed more light on the subject.

So “What is biochar?” I have really come to love that question. There are so many possible ways to answer it. Not one of which should be a canned, never to be changed, 30 second elevator speech. Biochar cannot be so easily squashed into such a tiny immobile box. I think it is really important to figure out who is asking the question, what will most resonate with them and then provide an answer that will inspire them to want to know more about biochar. Are they environmentalists looking for some technology to give them hope that it might be possible to somehow mitigate the looming climate chaos? Are they farmers that care about the bottom line but want to be sustainable? Are they climate skeptics that will be turned off the minute you mention carbon sequestration? Are they investors looking to make a quick buck on the next big trend? Often it is some combination.  Often you may not know. Fortunately for me the conference context gave me a pretty big hint as to the type of folks likely to be asking that question!

There are many, many different ways to talk about biochar. The framework I use is outlined in the picture above. The rest of my presentation at the NYS Conference on the Environment can be found here

Dispatches from Down Under #2

Australia #2

Farm-scale biochar production equipment from that land of Oz.

Farm Scale Biochar Production Technology in the US has been a bit hard to find if you want something more than a typical TLUD (top lit updraft). (Although I was happy to see this current kickstarter looking for funding to build an interesting model!) I’ve read about different technologies available in Australia so I was really happy to get a chance to see some of these up close or at least talk to some of the developers of certain units. Here is a quick glance at a few of the options from down under.

Big & Little Roo – I saw both of these in operation at the Living Community Festival. The Little Roo is a nifty little machine that can be placed over biomass such as a bale of straw. After carbonization the machine is lifted and the biomass quenched with a hose. Big Roo can char a whole lot more biomass which is put into what is basically a metal cage then inserted into a closed environment. Bamboo, coco nuts and more where carbonized in under 2 hours and then quenched with a hose when charring was complete. There looks to be lots of controls for temperature on this machine.

The Kon-Tiki Tas is a variation on the Japanese cone Kiln as well as a variation on the Kon-Tiki Kiln which has been developed by the Ithaka Institute (full disclosure and happy confession – I work with/for Ithaka!). This kiln is an open fire burning process which allows for easy charring of feedstocks which can sometimes be difficult to handle such as vineyard waste or gorse, a prickly evergreen shrub which is hugely invasive and now covers more than 100K hectares on Tasmania alone and is generally just burned in situ (more on that topic in a future post). After charring, the burn is quenched from below which makes for a very efficient dousing. The quench water, which has a high pH, can be saved and used on fields.

The other two units pictured were not at the conference due to the long distance, but I had chats with the developers about them. James Joyce is the brain behind BIGchar, made by Black Is Green, and Euan Beaumont talked to me about his mobile unit called the Puffing Billy. Both look to be efficient ways for farmers to upcycle underutilized biomass and turn it in to biochar. Not only does this help create closed loop biochar production and use scenarios, but they would definitely help make biochar more affordable and attractive to the agricultural community.  More win-finity!
