Hi Ron -  is there a link to the webinar? (Elias helped with some of the Stockholm study tour logistics so I could reach out to him if there isn't one.)

There is a lot going on in Sweden, Finland and Norway when it comes to biochar. The 2021 biochar study tour may be to Norway if things go as planned. They have a very organized biochar association there that is keen to host.

Cheers

Happy new  year to all. 
Much has been written on biochar. In this group the talk seems to be mainly about making biochar, but how exactly it works in the soil and on plants is still a mystery to me. Since it is applied to the soil, it must be 1.making more minerals available to plants 2.bettering the soil structure, 3. increasing water supply to the plants 4. offering shelter to beneficial soil microbes 5 all of the above. Since carbon does not dissolve in water and also does not biodegrade, the contribution of biochar might be due to its physical structure. Has anybody compared the effect of biochar with any other material having similar physical characteristics, e.g. broken pieces of terra cotta pottery, pumice, wood chips etc. In my own trials I found that application of raw, non-composted sugarcane bagasse to the soil also causes yield increase in crops, but I did not compare it with biochar, because our soils are extremely alkaline (pH above 8.5) and biochar does not work here. Bagasse is light and porous, it degrades rather slowly in the soil because the cellulose is tightly bonded to lignin. Bagasse is a leftover product of sugarcane after the juice has been extracted from it. Due to the rigorous way in which the juice extraction takes place, almost no water soluble material is left in it. It also has practically no minerals of use to plants in it except for potassium silicate.

Merry Christmas All,

Thought I'd drop a lump of hi-tech coal in your stockings. Carbon foam looks like a high-quality biochar from the description by the USFS. The recent winners of the Keeling Curve prize may be using it as a substrate to form catalysts for CO2 capture (see paper by Ma et al. under References). Biochar may yet end up being the biggest solution to global warming, but under a different moniker and in a way most did not anticipate.

Hello Tom & Robert,
Thanks for this shared exchange of considerations about planning, responsible, sustainable, optimum projects.
Thermal energy is the key where pyrolysis & gasification will have their strength in co-generation of chars / Biochar, Feedchar, Filtrationchar, Constructionchar, Designerchars …
Mobility is another consideration of scale. Feedstock logistics and availability over time throughout the year and the time over the whole estimated lifetime of the project.
Ideally thermal energy clusters involving various organic waste streams in a local  industry area and possibly neighbouring domestic community interests, the shared needs for thermal energy are very interesting and projects with great potential of success. This is where a multi service provider with expertise in Biochar and reliable Industrial Service could find real shared success opportunities.
Every industrial scale project involving employees etc. will need to be planned with the full mind mapped out and examined by all stakeholders involved.
Co-operative models as they are successfully operating in some countries are based on a shared cultural, intergenerational commitment.
I would love to see this happen here in Tasmania ‘under Down Under’.
Maybe 2020 is the time when things come together, let’s keep exploring and build the shared understanding of what makes total sense.
Cheers from a very hot (~  +40°C
) December

Rob,

 

I am sure there are recent life cycle cost assessments of small scale biomass power plants since they are required for most public projects. The challenge with most small scale power plants is that the cost of the equipment and labor often outweigh fuel savings from renewable fuels.

 

If I recall there is a small turbine at the VA hospital in White River Junction. Small backpressure turbines require large heat demand. An example of small power generation with large heat demand is a small 500 kWe turbine at a sawmill right there across the river in New Hampshire which heats a very large number of wood dry kilns. I think it was installed in about 2000. Organic Rankine Cycle (ORC) systems are often suggested but they also have very large low quality waste heat effluent that must be justified economically. They are best applied is you already have a hot oil boiler with excess heat capacity.

 

We looked at a small, 500 kWe, gasifier with an internal combustion engine recently but the low cost of heat and power did not make it feasible, even with biochar as a co-product.

Thank you, Tom, for your informative reply. 

I am involved in a project with a VT campus, where a new power plant needs to be installed to replace an old one being decommissioned. I have presented a woodchip plant and they liked it. The issue needs to be decided by the State Building & Grounds department, who operate under a State Law that says: 

"life-cycle costs" shall mean the present value purchase price of an item, plus the replacement cost, plus or minus the salvage value, plus the present value of operation and maintenance costs, plus the energy and environmental externalities' costs or benefits. Where reliable data enables the Department of Buildings and General Services to establish these additional environmental externalities' costs or benefits with respect to a particular purchasing decision or category of purchasing decisions, that is energy related, the Department may recommend the addition or subtraction of an additional price factor. All State agencies shall consider the price factor and environmental considerations set by the Department when examining life-cycle costs for purchasing decisions."

Are there examples of Life Cycle Assessments available for review, so that I can prepare to present this to Buildings & Grounds?  If I can prove that a modern biomass plant has a competitive result, it may open the doors to other state facilities.


Happy new year to you all. 


Re: Biochar and Stormwater Runoff #stormwater #green infrastructure #stormwater #green

We see good market potential in stormwater. Biochars are currently being used in several commercial stormwater applications. Companies like Gulleywasher and Stormwaterbiochar.com have been using biochar in filtration systems for more than 10 years. Biological Carbon LLC, Rexius and others sell biochar media for stormwater systems and filtration hardware. Biochars and biochar based products are excellent for capturing and remediating metals and bacteria. Civil engineers are finding cost benefits compared with activated carbon in some applications.  Large scale “facilities” (stormwater structures, filters, swales ) incorporating biochar have been in place for several years. Biochar has been included in at least one state stormwater manual. It needs to be included in more state and national design guides for Best Management Practices (BMPs) for landscaping (ASLA), and civial engineering so that it can be specified as an approved media for stormwater. Biochar and media suppliers tell us that public contractors allow “approved equal” so that contractors sometimes find cheaper alternatives to more expensive biochars.  

 

Several university groups working on stormwater have reported on their progress each year at biochar and stormwater conferences. Dupont reported n their use of biochar to remediate mercury using products from BiocharNow.  A consortium of universities (UC Berkeley, Stanford, Colorado School of Mines) has been working on biochar and stormwater for several years. They recently installed a system for cleaning water to recharge an aquifer using biochar from Oregon Biochar Solutions. University of Idaho Cool Terra biochar in a prize winning phosphorous removal system. Several universities (e.g. University of Florida) have developed biochar based media for metals removal.

 

Several companies have developed biochar based biotic soil amendments for erosion control and revegetation. Permamatrix was an early entry. It quickly joined Profile Products and their Proganics products. Mirimichi Green incorporates their CarbonPN product. They supply a well-known fertilizer company, LESCO, which introduced their granulated and liquid biotic soil amendments called CarbonPro at this year’s Golf Superintendent Associationof America conference. They distribute through a company that distributes to stormwater, erosion control and landscape contractors nationwide.  

 

If it depended just on compliance with EPA NPDES water discharge permits the market would be limited but green infrastructure for water quality is growing and the household, local, state and regional level.

Densified wood & biochar #densification

I liked Hans Peter's email received today and the corresponding article on densified wood finishes with a mantra for the new decade Transforming industrial products into biogenic carbon sinks. https://www.biochar-journal.org/en/ct/101-Carbon-Sink-Products

This got me thinking about the esteemed Macadamia NutShell, claiming to be the densest biomass on earth and it potential recycling into all sorts of products including the body of a car instead of being burnt to ash in boilers for energy as it is in Australia.

Biochar at the Transportation Research Board Annual Meeting, Washington DC, January 12-16, 2020

 

Reducing Stormwater Runoff Volumes with Biochar Addition to Highway Soils

Final report, December 2019

 

Stormwater runoff from roadways is a major source of pollution, but current stormwater treatment technologies, such as bioretention cells, do not efficiently remove contaminants. New technologies are needed that can both remove more pollutants and reduce the volume of stormwater discharge. Such technologies will not only improve water quality but result in significant cost savings for state departments of transportation. Biochar, made by pyrolyzing biological material such as wood chips, may increase water infiltration when used as an amendment in stormwater bioretention cells. Here, the authors examined how biochar contributes to soil aggregation, which in turn improves water infiltration in soil. The authors show that biochar changes production of adhesive macromolecules (proteins and polysaccharides), and that particles in biochar-amended soil are, on average, larger in diameter than those in un-amended soil. These macroaggregates likely form on time scales of months to years, suggesting that biochar may be an amendment that increases in effectiveness over time.

I spoke with the scientist who is developing this project. It looks amazing but very complex. He was thrilled that somebody had noticed his work and called to discuss it. When I mentioned pyrolysis, it was like we were cousins.

I can think of dozens of uses -- but development is hampered by the scientist's access to tools and equipment. The sample shown in the story is 6" X 6" which is the largest sample they can make in the oven they use. As a courtesy, I asked him to elaborate on the specifications for the oven, so I might reach out to our community to see if there is a larger unit he could use to accelerate testing. Maybe there is a university that could work on the project to move it along to commercialization faster. 

The product is patent pending, and I tracked down the office which licenses it. If anyone is interested, I can respond to further inquiries about that.

Hi Rob,
thanks for the questions, I’ll try to answer best I can.
I’m also just about to run another burn as material is piling up, I’ll be able to share more pictures, what is the best way to do that?
[RWL:   Doing same is fine by me.

I’m sharing land with an organic market gardener, and waste cardboard seem to be an abundant resource.

in terms of your questions:
1. The picture with the bones at the bottom was aimed at showing the bottom of the kiln, I don’t tend to place the bones at the bottom as it’s the place receiving least heat, and bones do not seem to char well there.
[RWL:   Gotcha.  See note below on possible BLDD to replace TLUD operation - which would keep the bones low.

2. I usually start with a bottom layer of sticks, to make sure that the flatness of paper does not block any air intake, the sticks allow even distribution of air. The picture showing the sticks also shows the next layer up of rolled cardboard, starting the stacking from the outside and not yet complete in the center, the sticks are only at the bottom layer.
      [RWL:  I thought I was looking at topmost layer.  Thanks for noting this.

3. Stacking the rolls of cardboard, paper, newspaper works well, and does not seem to matter upright or horizontal.

4. Nut shells or tree bark when available work well as a complete layer.
[RWL:   Intresting that you think in terms of layers.  I have not previously heard that.

5. Bones, egg shells, fruit stones, avocado skins and other such material seem to char best scattered evenly through the paper/ cardboard mass in the top part of the drum.

6. In terms of the design of the kiln, I have seen ‘aqueous solutions’ using both of the approaches, the 2nd drum as a chimney or a third of a drum attached to a flue as a chimney, I chose the later as I had the flue and it seemed lighter and easier to remove at the end of the burn.
i followed their design exactly, and I am very happy with it, I have used TLUDs before, and this one is the cleanest burn homemade TLUD I have constructed and used.

7. Regarding the question about my satisfaction with the resulted char... I’m not sure, which is why I shared this material to start with.
its all charred right through, including the bones, has no smell or taste, washes off easily with a bit of water, soaks up liquid well, and powders without effort, but I had not managed to find any information on the structural characteristics of paper/cardboard char, and I had not run any field trials.

i have been using that char in 2 main ways:
1. Mixed with grass clippings or wood shavings in our composting toilets, so every time someone does their thing they add a handful of the mix into the chamber, once full it sits for six months to decompose, red worms are abundant in the chamber too, after six months the compost is used in the garden or as part of seed raising mix.

2. Our family lives from the farm animals and our garden, and urine is an important resource.
my understanding is that each liter of urine has approximately 10ml of N, and that bacteria consumes approximately 5:1 C:N, so I either mix 50ml of humates with every liter of urine, and that’s spread onto the garden / forest garden (diluted).
Or the urine goes into the dry paper and co. biochar to soak for a few days, then the liquid (black urine) is watered into the garden, and the saturated biochar is forked into the garden soil.

i should run some simple field tests.
[RWL:  Looks like you are doing everything right.  I look forward to hearing what happens as you compare different amounts vs a control. 

as well, I read somewhere about a characterisation project? Aiming to link feedstock, pyrolysis method and resulted biochar?
I had not managed to find the database, is this in existence? Common knowledge to this list? How would one get access to the information?
[RWL:   There is a H-P Schmidt paper on this I’ll try to find.  Also compares good (seasoned) and bad (raw) char.

And has anyone seen some info on the structural characteristics of paper/cardboard biochar?
[RWL:  I’ll try to look tomorrow   I don’t recall any.


hope I clarified a few points.. :-)
[RWL:  Yup.   You’re really on to something new I think.  New and likely important.

Re the BLDD idea - I will try to send more - but the basic idea is to use your existing 200 liter barrel exactly as is - but light at the bottom.  Open (cold top).  The needed downdraft supplied by the existing tall (small diameter) chimney a few feet away.  Flames to travel horizontally those few feet in a trench in the ground - covered by a piece of steel (on which you could cook/boil something (sort of like a Plancha).  I’m claiming not much new equipment needed except the flat horizontal steel plate.

The probable main new problem is getting a fire stated at the base.  Second need is for a way to regulate the needed secondary air.

A proposed advantage over TLUD operation is early being able to start with small height of fuel (better draft) and keep adding fuel until the barrel is totally full rather than half(?) full.

I don’t know of this ever being tried.  For most of us a major difficulty - but you have most of the gear already.

Again - thanks for doing what you are doing.  

Ron. (Not Rob)

Biochar Friday 2020    (The attachment is exactly like the message below, but is in  .docx   format.)

 

Dear all      (but directed to those who deal with Biochar issues and/or who could be attending the ETHOS meeting in Kirkland, Washington on 24 – 26 January 2020),

 

Within the regular attendees of ETHOS there is a “mini-sub-group” with an interest in biochar, especially the production of biochar such as with TLUD cookstoves and barrels and other small pyrolysis devices.  Because we are together each year, it is proposed that we have a separate (but coordinated) meeting about biochar on the Friday (24 January this year) before ETHOS starts. 

 

After some few comments from others via email, I have made the following arrangements for the Biochar Friday group:

 

1.  The Biochar Friday group is to have its first gathering on 24 January 2020. 

 

2.  The meeting room of the Kirkland Inn (connected to the breakfast room) has been reserved for the morning of 24 January.   ETHOS controls that meeting room from noon onward.   (There is no option to meet at Shari’s restaurant.)

 

3.  We will gather at 8:00 AM, with an on-time official start at 9:00 AM.   Tom Miles has offered to provide a summary of the status of international (and USA/North America) biochar activities (not just about the organizations called “Biochar Initiatives.”)   How much time he has will be determined after others have had a chance to make proposals for the use of the time.   One additional topic could be the role of PyCC (Pyrolytic Carbon Capture) to assist the battle against climate change.   Perhaps there will be some panel discussions, depending on who attends.   It will NOT be with academic presentations.   The focus is NOT on the agricultural / soil / micro-fauna / etc. aspects of biochar, but such can be mentioned. 

 

4.  We will ask ETHOS leadership if we can extend our time past noon, up to the time when ETHOS will have its use of the room (usually starting at 1:00 or 1:30 PM).  

 

5.  Because the Woodgas TLUD stoves are makers of charcoal / biochar, they could be featured in the afternoon time reserved for ETHOS, but that is up for discussion.  

 

6.  Upon expiration of any time for Biochar topics in the room, the Biochar Friday group is at liberty to move to another location (not defined).  If the group is small, that will be easy.   If numerous, we can be creative with specialty groups or focus groups. 

 

***************

So, the Biochar Friday event is now official.  It is open to everyone.  You can make your travel arrangements to allow your presence at the event.  Remember to register for the ETHOS meeting (at   www.ethoscon.com    , and to reserve your room at the Baymont Inn at Seattle/Kirkland:   425-947-1030  (and say that you are with ETHOS.)

 

There is no charge for Biochar Friday but donations to cover the room rental (AM only) will be accepted at the event (unless we find a sponsor).  

 

This announcement is going to three (3) Listservs but could be forward to others by you:  Biochar group, Stoves Listserv, tluds Listserv.    And ETHOS could send it to its mailing list.   Please reply to your respective listservs, but know that not everyone will see your replies.   Especially if you expect to attend the Biochar Friday, be sure that I receive notification  (  psanders@...  ).  

 

I (we) are looking for some volunteers, but not sure what duties there are to be undertaken.

Re: Waste cardboard, paper, newspaper, as feedstock #feedstock

Shaked From
 

Hi Rob,
thanks for the questions, I’ll try to answer best I can.
I’m also just about to run another burn as material is piling up, I’ll be able to share more pictures, what is the best way to do that?
I’m sharing land with an organic market gardener, and waste cardboard seem to be an abundant resource.

in terms of your questions:
1. The picture with the bones at the bottom was aimed at showing the bottom of the kiln, I don’t tend to place the bones at the bottom as it’s the place receiving least heat, and bones do not seem to char well there.

2. I usually start with a bottom layer of sticks, to make sure that the flatness of paper does not block any air intake, the sticks allow even distribution of air. The picture showing the sticks also shows the next layer up of rolled cardboard, starting the stacking from the outside and not yet complete in the center, the sticks are only at the bottom layer.

3. Stacking the rolls of cardboard, paper, newspaper works well, and does not seem to matter upright or horizontal.

4. Nut shells or tree bark when available work well as a complete layer.

5. Bones, egg shells, fruit stones, avocado skins and other such material seem to char best scattered evenly through the paper/ cardboard mass in the top part of the drum.

6. In terms of the design of the kiln, I have seen ‘aqueous solutions’ using both of the approaches, the 2nd drum as a chimney or a third of a drum attached to a flue as a chimney, I chose the later as I had the flue and it seemed lighter and easier to remove at the end of the burn.
i followed their design exactly, and I am very happy with it, I have used TLUDs before, and this one is the cleanest burn homemade TLUD I have constructed and used.

7. Regarding the question about my satisfaction with the resulted char... I’m not sure, which is why I shared this material to start with.
its all charred right through, including the bones, has no smell or taste, washes off easily with a bit of water, soaks up liquid well, and powders without effort, but I had not managed to find any information on the structural characteristics of paper/cardboard char, and I had not run any field trials.

i have been using that char in 2 main ways:
1. Mixed with grass clippings or wood shavings in our composting toilets, so every time someone does their thing they add a handful of the mix into the chamber, once full it sits for six months to decompose, red worms are abundant in the chamber too, after six months the compost is used in the garden or as part of seed raising mix.

2. Our family lives from the farm animals and our garden, and urine is an important resource.
my understanding is that each liter of urine has approximately 10ml of N, and that bacteria consumes approximately 5:1 C:N, so I either mix 50ml of humates with every liter of urine, and that’s spread onto the garden / forest garden (diluted).
Or the urine goes into the dry paper and co. biochar to soak for a few days, then the liquid (black urine) is watered into the garden, and the saturated biochar is forked into the garden soil.

i should run some simple field tests.

as well, I read somewhere about a characterisation project? Aiming to link feedstock, pyrolysis method and resulted biochar?
I had not managed to find the database, is this in existence? Common knowledge to this list? How would one get access to the information? And has anyone seen some info on the structural characteristics of paper/cardboard biochar?

hope I clarified a few points.. :-)

happy celebrations
which ever you carry
