This site has been created to facilitate the establishment of a South East Asian biochar interest group. BIG-SEA could provide communication and linkage between biochar researchers, farmers, related industry and supporting organisations, interested in tropically focused biochar industry development. Please get in touch if you are interested in supporting or participating in this effort.
where does food waste best fit in a waste hierarchy? does it have better utility as animal feed or in a localised BSF industry
what sort of H&MB numbers are going to work at scale, with all that water to remove? is hydrothermal carbonisation a better path for this type of waste stream
recovering P from our industrial food and sewage systems is important... is biochar production going to become a key player?

Abstract
The disposal of a large amount of biogas residue
from anaerobically digested food waste is a burden for biogas
production. The aim of this work was to investigate biogas residue as a
potential feedstock, by preparing biochar at a broad pyrolysis
temperature range of 400–900 °C. The properties required for phosphorus
recovery and soil amendment application were evaluated. Biogas residue
collected from an urban food waste treatment plant was pyrolyzed in a
laboratory scale reactor. It was found that by increasing the pyrolysis
temperature, the yield of biochar decreased and the pH, electrical
conductivity and Brunauer–Emmett–Teller surface area increased. The
amount of phosphorus adsorbed onto the biogas residue-derived biochar
(BRB) at 900 °C was larger than that of other kinds of biochar. The
kinetics of phosphorus (P) adsorption on BRB could be described by the
pseudo-second-order equation. The pot experiments showed that the
resulting biochar is beneficial for the growth of cabbage. Overall,
turning solid residue from the anaerobic digestion of food waste for
biogas production into biochar shows good prospects as a means of
solving the disposal problem, while creating new markets for food waste
biogas residue.

"Lots of people expressed interest in the post-trough, post-Kontiki, tench solution to making char in the field without water. Here's a really simple, two minute video shot using our original test trench. In a few months when the corn harvest is in, I'll shoot a more real one up in the mountains. For now, this will have to serve. It is not, as you will see, rocket science, and as long as you dig the trench during the rainy season, there's not much work involved."

From: Paul Olivier Date: Mon, 12 Nov 2018 at 17:26 Subject: street kitchens in Vietnam
A street kitchen in Vietnam is generally a grave threat to human health and the environment. A street kitchen typically burns coal, charcoal or firewood. The lighting of these solid fuels usually emits a cloud of black smoke. When these solids fuels are combusted, high levels of benzene, particulate matter and CO stream forth in all directions. But perhaps, still worse, are the highly carcinogenic cooking oil fuels.
Near the University of Dalat, there are several street kitchens close to one another. They emit large quantities of cooking oil fumes. These cooking oil fumes combine with particulate matter and nitrogen compounds (emitted by sewage lines), and when these pollutants enter the human lung, they stick there and do not come out. People get sick, and people die.
Here you see jpegs of a 150 gasifier equipped with a 3-sided wind shield, a 40-liter biochar filter, a hood and a fan.
The 150 gasifier emits levels of benzene, particulate matter and CO well within the norms specified by the World Health Organization. When cooking oil fumes are pulled through the biochar filter by means of a small fan above the round hood, they stick to the biochar and not to the human lung.
The solid fuels typically used by street kitchens are costly. But with a gasifier, one has high-grade heat at a profit, since the biochar pellets produced in the gasifier have a greater value than the raw pellets from which they are derived. In other words, one has high-grade heat at a profit.
When biochar is produced in a gasifier, dirty and highly-polluting biochar kilns are not needed. In Dalat I have seen biochar kilns that emit, day after day, huge clouds of smoke.
Gasifiers can be powered almost entirely by agricultural waste biomass, such as rice hulls and rice straw. To the extent that such waste biomass would be pelleted and used as gasifier fuel, the useless burning of this waste would not take place.

IBI Educational Webinar Series: Biochar for Sustainable Soils (B4SS)
11/29/2018Presented by Ruy Anaya de la Rosa Biochar
projects spanning multiple countries are still relatively few and far
between. There is much to learn from these types of multinational
projects. IBI has invited Ruy Anaya de la Rosa, the Project Director
from the recently concluded Biochar for Sustainable Soils
(B4SS) to discuss lessons learned, challenges and best practices from
his experiences collaborating biochar projects teams in China, Ethiopia,
Indonesia, Kenya, Peru and Vietnam.
B4SS was funded by the Global
Environment Facility (GEF) under the Land Degradation Focal Area in the
GEF-5 Strategies. The objective of the B4SS was to demonstrate and
promote the adoption of sustainable land management practices involving
the use of innovative organic amendments, based on biochar, that improve
the capture and efficient use of nutrients, and enhance productivity,
improve climate resilience, support rural livelihoods, and contribute to
watershed management. A key goal was to promote the diffusion and
successful adoption of biochar techniques among B4SS partner countries
and beyond.
The project was focused on collating knowledge
generated through the implementation of the targeted biochar
demonstration projects. Awareness and improved understanding amongst
smallholders, including women’s groups, and resource managers about the
most effective biochar formulations and application rates to improve
soil functions and reduce land degradation, will be created and shared
among stakeholders. This integrated global approach to advance the
knowledge on the use of biochar for SLM also conveyed other messages to
farming communities mainly interested in soil improvement.

The efficiency of phosphorus uptake by
plants in an Ultisol soil is very low because most of soil phosphorus is
precipitated by Al and Fe. Oil palm empty fruit bunches can be used as
basic materials of biochar and compost, and as sources of isolates of
phosphate solubilizing fungi. This study was aimed to elucidate the
effect of application of phosphate solubilizing fungi with biochar and
compost generated from oil palm empty fruit bunches on growth and yield
of maize an Ultisol of Central Kalimantan. This study consisted of two
experiments. The first experiment was inoculation of four isolates of
phosphate solubilizing fungi isolated from of oil palm empty fruit
bunches, i.e. Acremonium (TB1), Aspergillus (TM7), Hymenella (TM1) and
Neosartorya (TM8) to 'biocom' media (mixture of biochar and compost
generated from oil palm empty fruit bunches) to obtain phosphate
solubilizing fungi that can adapt to the media. In the second
experiment, the best results in the first experiment were applied to an
Ultisol soil planted with maize. The results showed that isolates that
were best adapted to biocom media were Aspergillus-TB7 with 60:40
proportion (60% biochar + 40% compost) and Neosartorya-TM8 with 70:30
proportions (60% biochar + 40% compost). The application of the first
experiment results to the second experiment showed that the application
of biocom plus Neosartorya-TM8 (BTM) on an Ultisol soil significantly
improved growth and yield of maize, as well as phosphorus uptake and
efficiency of phosphorus uptake by maize.

Subject: [Stoves] Short Documentary on TLUD and Biochar in Bangladesh (in Bangla)
Hi folks;
Here is a short doc on TLUDs and biochar in Bangladesh. It is in Bangla,
but I am sure we can all understand the body language for 'migrating
pyrolytic front', 'cation exchange capacity', and 'sodium chloride'.
The significance of this video is that Bangladesh is a nascent hot-spot of
TLUD and biochar research, because it is probably the most ideal country in
the World for these technologies: 3 crops per year, low organic matter
soils, 80% of population cooking with biomass, >1000 people / km?,
impending loss of land to sea level rise, and plenty of scientists.
It is great the way this video includes both the university professors,
farmers and lots of women. The CCDB project has collected data showing
that university professors increase the self-esteem of women TLUD users, so
it is recommended that professors should be applied liberally in the
countryside to increase cookstove acceptance.
I hope subtitles in English are forthcoming.
Cheers,
Julien.

Dear Friends of Ithaka,
The prospects of climate change are so increasingly dire that there
are times when it may seem inappropriate to celebrate a promising
scientific advance or any other good news. Good news, however, is
exactly what humanity needs at moments like this. And to produce good
news, it helps to share them and to create examples that others might
replicate.
One such bright spot in the dark is the inclusion of biochar and
pyrogenic carbon capture & storage (PyCCS) into the recent IPCC
special report. It took more than ten years of global biochar science,
technology development and practice before it finally appeared serious
and convincing enough to the world’s leading climate scientists to
mention biochar-based carbon sequestration as a technology to consider.
It may take another five years until policy makers discover and discuss
this most promising solution to keep global warming in a range that may
still sustain civilization in all regions where human culture prospered
during the last millennia. Five more years for us to prepare the
groundwork with sophisticated technology, understanding of mechanisms,
sustainable certification, and valuable biochar based products. See
linked below our extended comments and the decisive, biochar related
passages from the new IPCC special report.
At Ithaka we have been hard at work on various other positive
developments which we hope will provide inspiring examples such as the
forest gardens with organic biochar-based fertilization that we set-up
in Nepal. A local journalist, Abhaya Raj Joshi, recently visited one of
the villages where more than 50,000 trees were planted and have been
linked to a global carbon subscription model since 2015. He interviewed
villagers on how the new climate farming methods have changed their
lives and the village.
And last but not least, Kathleen’s new, updated white paper on using
biochar in coffee production with lots of new success stories about
using biochar in coffee production and processing from three different
continents. Thanks to funding received by the Biochar for Sustainable
Soils project, you can enjoy the complete white paper with open access.
The Ithaka team will be traveling to Cuba, India, China and the UN
climate conference in Poland over the next months to continue with
education, research, collaboration and in-field biochar initiatives. As
always, we will share with you what we learn and what we believe may be
of service to others. We always appreciate hearing about successes and
lessons learned by others working collaboratively on biochar projects
around the globe, please feel invited to share these with us.
Yours Hans-Peter and Kathleen
Biochar and PyCCS included as negative emission technology by the IPCC
by Hans-Peter Schmidt
Biochar was included for the first time as a promising negative
emission technology (NET) in the new IPCC special report. While the
special report’s overall message was alarming, the inclusion of biochar
is an important milestone for mitigating climate change and fostering
research on pyrogenic carbon. We provide here a short summary on
pyrogenic carbon capture and storage (PyCCS) and relevant excerpts from
the new IPCC special report with regards to PyCCS and biochar. ... mehr
Carbon sequestration to rejuvenate land, water and economy in Nepal
by Abhaya Raj Joshi
Three years after the first 10,000 forest garden trees were
planted in a Nepali mountain village and were linked to a new type of
private carbon trading scheme, the village received the visit of a young
journalist from a national newspaper. His particular insights into the
Nepali way of life and policy, make his report about this acclaimed
pilot project combining organic biochar based fertilization, mixed tree
garden plantation, water retenition, soil conservation, and crop value
chain creation a passionate critic. ... mehr
Pyrogenic carbon capture and storage
In this review, we show that pyrolytic carbon capture and storage
(PyCCS) can aspire for carbon sequestration efficiencies of >70%,
which is shown to be an important threshold to allow PyCCS to become a
relevant negative emission technology. Prolonged residence times of
pyrogenic carbon can be generated (a) within the terrestrial biosphere
including the agricultural use of biochar; (b) within advanced bio‐based
materials as long as they are not oxidized (biochar, bio‐oil); and (c)
within suitable geological deposits (bio‐oil and CO2 from permanent
pyrogas oxidation). ... mehr
Biochar & Coffee White Paper
by Kathleen Draper
An increasing number of coffee growers use biochar to improve
soil fertility and resiliency, reduce dependence on fertilizers, achieve
better survival rates for young plants, increase disease resistance and
optimize residue management. New peer reviewed information on how
biochar can help mitigate coffee rust (roya) and other diseases is
presented in addition to benefits related to soil fertility, composting,
effluent filtration, renewable energy production, residue management
and reduction of greenhouse gas emissions across the entire coffee
supply chain. ... mehr (<
• Biochar has potential to be the best management practice for low fertility soils.
• Biochar coating with organic materials can result in enhanced crop nutrient supply.
• Biochar may accelerate the composting process and improve the end-product quality.
• The influence of biochar varies strongly according to the types of feedstock/soil.
Abstract
Rapid
industrial development and human activities have caused a degradation
of soil quality and fertility. There is increasing interest in
rehabilitating low fertility soils to improve crop yield and sustainability. Biochar, a carbonaceous material
intentionally produced from biomass, is widely used as an amendment to
improve soil fertility by retaining nutrients and, potentially,
enhancing nutrient bioavailability. But, biochar is not a simple carbon material with uniform properties, so appropriate biochar selection must consider soil type
and target crop. In this respect, many recent studies have evaluated
several modification methods to maximize the effectiveness of biochar
such as optimizing the pyrolysis process, mixing with other soil amendments, composting with other additives, activating by physicochemical processes,
and coating with other organic materials. However, the economic
feasibility of biochar application cannot be neglected. Strategies for
reducing biochar losses and its application costs, and increasing its
use efficiency need to be developed. This review synthesized current
understanding and introduces holistic and practical approaches for
biochar application to low fertility soils, with consideration of
economic aspects.
NCAT’s own Jeff Schahczenski, agriculture and economics
specialist, published an article about biochar and organic agriculture
that was featured in the Organic Farmer magazine. Jeff writes
that biochar in agriculture has become a “movement” but points out the
difficulties in even establishing a definition for it.
“The range of topics and issues surrounding biochar are immense and
unwieldy,” Jeff says. “If you don’t believe me, just check out the 2015
second edition of the book, Biochar for Environmental Management: Science, Technology and Implementation,
edited by biochar leaders Johannes Lehmann and Stephen Joseph. This
928-page tome is only the tip of the iceberg on the many, many topics
related to biochar. “
