Using Biochar to Improve Water Quality #water

Tom Miles
 

Using the example of our state of Oregon, how can biochars be used to:

·        Helped producers implement conservation

·        Reduce sediment loss

·        Reduce phosphorous loss

·        Reduce nitrogen loss

What cost effective practices can be implemented on farms or in forests?

See:

USDA Announces 2021 Priority Watersheds for Water Quality in Oregon:           http://www.nrcs.usda.gov/wps/portal/nrcs/detail/or/newsroom/releases/?cid=NRCSEPRD1677414

NRCS encourages state partners to begin collaboration on NWQI priorities for Federal Fiscal Year 2022, which begins on October 1, 2021. See the NRCS website for a list of the watersheds for NWQI.

Water quality is improving in NWQI watersheds. State water-quality agency partners report that 27% of NWQI monitoring watersheds show an improvement in water quality in at least one of the NWQI-monitored pollutants (based on 2016 data). Further, 81% of these improvements can be attributed to or associated with agricultural conservation practices implemented by farmers and ranchers.

 


Update on RoCC barrel kiln progress #pyrolysis #technology

Paul S Anderson
 

Biocharists,

 

I promised an update and reveal by the end of this week.   There is much progress, but also some lessons and business thoughts to present here.

 

The topic is a barrel-sized or slightly larger biochar maker (and biomass disposer) based on the RoCC concepts of covered flame-cap pyrolysis with mixing capabilities, but rather inexpensive (mainly DIY) and user friendly (IMO) for use by one adult.

 

1.  I made at least three significant variations that have resulted in firm designs and decisions for moving forward.   But I can already see further improvements, so today’s information is outdated.

 

2.  My work is in my garage and I use “scrap” when appropriate.   The result is wonderfully functional but not very pretty and not what should be built (direct replication) by others, or certainly not built for being sold to others.   Eventually (in 2021 I expect) to be a product.

 

3.  In addition to the fabrication, it takes time to properly test each unit.   One test with one fuel is not sufficient for releasing all of the information at this time.

 

THEREFORE,

 

a.  I am delaying for a few weeks the release TO THE GENERAL PUBLIC which would be the case of a posting on my website or via this listserv.   I am now shooting  for release of info during the USA National Biochar Week  of 7 to 11 December.   Info about that event is at:

https://docs.google.com/forms/d/e/1FAIpQLSfhqVkUZLQd-GVLKYR2ZdXDWrBjlyRLmRYLMkMZ9l30JRaovQ/viewform    

 

b.  I will receive and review any requests for personal private viewing of my current written materials and access to me for guidance.   This would be mainly from persons  who would  privately fabricate a unit based on my design AND incorporate differences to determine if there are improvements to be shared with others.  Accepted persons would be in the “inner circle” for development.

 

c.  So, if you really want to build (at your own expense) and you can work from photos and comments (but lacking detailed instructions or drawings), please write to me at    psanders@...      Include details that would be useful for me to assess your possible participation.

 

d. BUSINESS:   If you have business interests and/or a funded (fundable) project for biomass disposal via pyrolysis producing biochar, please do write to me.   Your geographic location could be to your advantage because I seek eventual wide-spread activities.

Hi Nicolas,

First, apologies for calling you by your surname previously.

Also, for suggesting your stove looked similar to an “Anita” stove. Auto-correct didn’t know the word Anila, and changed it on me!

Stoves like Edward Revill’s pipe TLUD and Paul Anderson’s FAB Stove in Africa(I can’t remember which country) both have the adjustable fan unit and pot stand separate to the fuel chamber/primary combustion unit. These units can be made with two fuel chambers, so you can empty and refill one, while using the other, thus making the recharge a little smoother.

If you need multiple stoves, I recall watching somewhere a YouTube video on TLUD planchas. Or a two pot system.

Maybe you could also have the rocket stove there for the larger, longer cooking pot?

Thinking on the run...

Thank you very much for all your responses!

It is true that TLUD is the best way to produce biochar. 3 years ago

we contacted Art Donnelly and made a FINCA type TLUD running on cow dung: 




However, when we tested in the field, we had several criticisms: that traditional houses need 3 burners at the same time and that the kitchen has the capacity to operate several hours in particular for large stock pot kitchens.
They also told us that it was quite "complex" to turn on the TLUD and that it could not be recharged while it was working.

Since then I stopped working on this issue and I became interested in bioclimatic construction in adobe.
The pandemic was an impulsive factor and a month ago, I  bought with several friends of mine a piece of land in the Sacred Valley in Cusco PERU and we are building bioclimatic houses in adobe.
I started to build a rocket stove with clay and tiles to cook our meals: 




Several neighbors saw this rocket and were very interested in building it. Then I remembered Edward Revill and his videos on his biochar rocket stove. The use of biochar has a lot of potential because the soils in the area are very compact and poor (very clayey and rocky). In the valley there was a lot of deforestation and they planted many eucalyptus.

I did some more research and found that video from which I was inspired to make the plans I sent you: 




It is true that in the video it looks like a cut and I suspect that it was not as easy as it seems. Surely an isolation would help a lot. I planned to make it with mud and straw to save costs.

Personally, I am going to build a new TLUD like the "finca" model I think and I will incorporate a water heater (see annex) We did a test  3 years ago and it works quite well.

In summary:

- I am interested in the development of a stove that allows cooking and producing biochar (that can be recharged and ideally has 2 burners)

- Produce biochar on a medium scale with house construction waste (mainly eucalyptus)
Thank you very much again for your precious comments!

Anila stove
The stove was designed by Professor RV Ravikumar, of the University of Mysore in India, and it can produce biochar on a household level. It is a TLUD with a double chamber design, which produces biochar and does not allow the biochar to be fully combusted in the unit.

In my opinion, forget about the Anila stove for serious  making of biochar.  It is an inside out retort with lots of external surface area to prevent the adequate heating to pyrolysis temperatures of the biomass that is too far from the heat source in the center.  And it is not a particularly good cookstove.    Maybe it is a learning tool to see what is important for making char and how not to do it.

I am applying for a grant to construct filters for stormwater management in environmentally sensitive locations. 

According to published studies, effective water filters can be made with biochar and various elements. For example, certain biochars have been demonstrated to filter phosphorous effectively (for one example) using a lanthanum zeolite compound in connections with specific feedstock, pyrolysis temperature, etc. - 

Is there a business (or research facility?) already in existence that can make filtration compounds to match the specifications of a scientific study and produce them at a reasonable price, in a real-world volume?  

If not, might this represent a good business opportunity?

Hello Kim,
It's a nice opportunity in the field of biochar. We found in research that sewage sludge biochar producing in pyrolysis temperature 320 ℃ is the highest container of available phosphorus. But the C-N ratio was higher in high-temperature biochar (520 and 620 ℃).

Re: New paper on water saving benefits of biochsr #irrigation #water

Group, I view one of the great values of biochar is that it facilitates the leaching of sodium salts from sodic soils (which contain clay).  

Sodic soils are those where the clay structure has been degraded from sodium salt. 
Sodium (+1) kicks out Magnesium (+2) and Calcium (+2), which causes the air filled porosity of the soil to degrade, making it hard for the microbes to respire. 

Please see the attached Ph.D. thesis from UC Riverside explaining these results. 
Biochar accelerates sodium leaching. Biochar works best in this role when it is accompanied by compost. 
What is interesting is that it is microbiome from the compost that is given credit for much of the benefit.  Sterilize the soil and the benefits diminish. 

I've leached sodic clay soils with this combination of biochar and compost.  Many times.

Re: Forest biochar rocket stove #stoves

Daniel Pidgeon
 

Hi Nicolas,

Gustavo Pena has posted on this group regarding his plancha. It looks good!


Regarding the minimal take-up of the stoves in your field trials, I like Kevin McLean's work with simply and cheaply tweaking existing used methods, using a bed of pebbles and a basic clay grate to get more air into the middle of the fire, making things more efficient and cleaner, at almost no cost. I looked for his posts on the group site, and the old site, but could not find them. This is a picture I found in an email of a set up that was created for demonstration, but that shows the simplicity of it. This is for a basic open fire, a three stone fire, but the concept of a grate to get more oxygen into the burn zone can be used on most, older style, wood fired cooking devices. With minimal changes to the user. One to keep in mind for the community at large, who are generally resistant to change...

Hi Nicolas,

First, apologies for calling you by your surname previously.

Also, for suggesting your stove looked similar to an “Anita” stove. Auto-correct didn’t know the word Anila, and changed it on me!

Stoves like Edward Revill’s pipe TLUD and Paul Anderson’s FAB Stove in Africa(I can’t remember which country) both have the adjustable fan unit and pot stand separate to the fuel chamber/primary combustion unit. These units can be made with two fuel chambers, so you can empty and refill one, while using the other, thus making the recharge a little smoother.

If you need multiple stoves, I recall watching somewhere a YouTube video on TLUD planchas. Or a two pot system.

Maybe you could also have the rocket stove there for the larger, longer cooking pot?

Thinking on the run...

Thank you very much for all your responses!

It is true that TLUD is the best way to produce biochar. 3 years ago

we contacted Art Donnelly and made a FINCA type TLUD running on cow dung: 




However, when we tested in the field, we had several criticisms: that traditional houses need 3 burners at the same time and that the kitchen has the capacity to operate several hours in particular for large stock pot kitchens.
They also told us that it was quite "complex" to turn on the TLUD and that it could not be recharged while it was working.

Since then I stopped working on this issue and I became interested in bioclimatic construction in adobe.
The pandemic was an impulsive factor and a month ago, I  bought with several friends of mine a piece of land in the Sacred Valley in Cusco PERU and we are building bioclimatic houses in adobe.
I started to build a rocket stove with clay and tiles to cook our meals: 




Several neighbors saw this rocket and were very interested in building it. Then I remembered Edward Revill and his videos on his biochar rocket stove. The use of biochar has a lot of potential because the soils in the area are very compact and poor (very clayey and rocky). In the valley there was a lot of deforestation and they planted many eucalyptus.

I did some more research and found that video from which I was inspired to make the plans I sent you: 




It is true that in the video it looks like a cut and I suspect that it was not as easy as it seems. Surely an isolation would help a lot. I planned to make it with mud and straw to save costs.

Personally, I am going to build a new TLUD like the "finca" model I think and I will incorporate a water heater (see annex) We did a test  3 years ago and it works quite well.

In summary:

- I am interested in the development of a stove that allows cooking and producing biochar (that can be recharged and ideally has 2 burners)

- Produce biochar on a medium scale with house construction waste (mainly eucalyptus)
Thank you very much again for your precious comments!

The stove was designed by Professor RV Ravikumar, of the University of Mysore in India, and it can produce biochar on a household level. It is a TLUD with a double chamber design, which produces biochar and does not allow the biochar to be fully combusted in the unit.

In my opinion, forget about the Anila stove for serious  making of biochar.  It is an inside out retort with lots of external surface area to prevent the adequate heating to pyrolysis temperatures of the biomass that is too far from the heat source in the center.  And it is not a particularly good cookstove.    Maybe it is a learning tool to see what is important for making char and how not to do it.

Re: New paper on water saving benefits of biochsr #irrigation #water

David Yarrow
 

biochar and clay have distinctly different water hold strategies.

my impression from field observations is that they complement and need each other.  the idea they compete is an error of insight; they form a partnership that can boost water retention beyond either alone.

biochar retains water in its micropore sponge structure, sucking water in largely thru simple capillary action.  biochar's electric charge sites on its surfaces enhance this capillary action by increasing the forces that pull water inwards, and then hang onto it once inside, but loosely.  

biochar has far fewer electric charges on its surfaces than clay, and thus, the water is not so tightly held.  thus, biochar rather rapidly dries out once exposed to atmosphere or heated.  a pile of biochar will develop a thin dry surface layer, while remaining moist inside.  and being black, char exposed to sunshine & atmosphere will heat up and dry out even faster.

however, biochar inside soil, in full contact with soil particles, will safely retain the water it absorbs into its hollow sponge spaces.

clay forms much more intimate bonds with water molecules.  its thick abundance of negative charge sites grab and hold those water molecules more tenaciously, and assembles water into clay-water complexes – hydrates.  thus, clay will stay wet longer than biochar.  however, clay also absorbs and retains water much more slowly, and clay is slower to allow water to pass thru and percolate deeper into it. 

on the other side, clay resist water absorption, in part because it is so fine, with tightly stacked & packed microplates, and narrow spaces in between.  further, as clay absorbs water and forms its hydrate complexes, it swells up, further reducing those spaces between its tiny particles.  so clay tends to shed water after its surface layer gets wet, and water is slow to penetrate deeply.  fortunately, as clay dries out , it shrinks and opens large cracks that will allow water to rush in deeper.

my impression is if biochar – or many other ultrafine carbon, like humic & fulvic acid – is added to clay, the carbon swarms & surrounds clay's strong electric charges, to isolate & insulate them, reducing their polar attractions and reducing stickiness.  this allows the mass of clay to relax and become more open.  this happens, too, in a different way, with larger pieces of biochar, further loosening, relaxing and opening the clay.  this means water can into penetrate into clay easier, faster, deeper.  so, while biochar slows water movement thru sand, biochar increases water movement thru & into clay.

so, what i like to do it blend biochar and clay together.  usually this means adding fine clay powder to biochar, so the grains of biochar are coated by the dust, and deployed into soil already in an intimate association, ready to work together to manage water and nutrients.  the biochar & clay don't just fall together, they become organized into complex structures that seem to serve functional purposes.  likely stephen joseph et al have research and microscopic views that reveal this structured partnership.

below is my slide for talking about water & biochar:

Maybe others on this list can add to the number of papers they could use - now mostly in the sandy corner of their soil triangle.  They couldn’t use some other potentially useful water saving papers because those didn’t provide all the possibly important explanatory variables.

Below is one view of the data set they used (lots more numbers in the Supplemental).   Anyone able to add points in the clay area?   The authors state that biochar is known to work well there also - but no data yet.
