UTAR Agricluture Science Journal: Biochar - reversing the flow of carbon

http://uasj.utar.edu.my/uasj/index.jsp?fcatid=18858

HERE is a link to an article on biochar that I've had published in the inaugural issue of the above journal (click on image above for link to the journal).


This is a general introduction to biochar with a focus on history, applications, climate change and carbon sequestration. I hope to say more about biochar production and industry development in SEA in a followup article.

Campfire Lessons: Breaking Down the Combustion Process to Understand Biochar Production

This new article from The Biochar Journal is another great introduction to biochar production and application...

By Mark R. Fuchs, M. Garcia-Perez, P. Small and G. Flora

“Campfires were the first step in the evolution of slow pyrolysis reactors. Observing the play of the flames while sitting around a campfire is still one of the best possible lessons to understand the main principles of pyrolysis. Mark Fuchs and colleagues bring the different natural phenomenon of the fire into context of modern pyrolysis.” …

Reviewer comment

Catherine Brewer:
One of the frequent challenges experienced by members of the biochar community is figuring out how to explain biochar and biomass thermochemical processes to friends and family members. The authors’ use of the campfire illustration is so helpful because it is familiar to a wide audience and scientifically accurate at the same time. After hearing this illustration the first time myself, I remember thinking, “I will never again see just a campfire.”

Estero clean-up project in UP community - Philippines

I assume estero is estuary but I've not had luck finding a translation...
http://manilastandardtoday.com/2015/01/03/estero-clean-up-project-in-up-community/

"The estero running through Block 5 in Daang Tubo (a community inside the UP Campus) is on its way to being clean.
GMA Network and its partners, the Philippine Mine Safety and Environment Association, the Philippine Biochar Association and the Sagip Ilog Pilipinas, collaborated on the Clean River Zone Biochar Community initiative.
The Kapuso Network and its partners signed a Memorandum of Agreement in early 2014 to clean up the said estero using bokashi balls (bokashi balls are made from dried mud and other organic materials, including biochar, and are used to clean bodies of water that have high concentrations of sludge and slime)." ...

Report: Biochar on acidic agricultural lands in Indonesia and Malaysia


I've been aware of a collaborative biochar research program that has been running over a number of years, led by Gerard Cornelissen from the Norwegian Geotechnical Institute with participation from researchers in Malaysia and Indonesia. I have now discovered that this work has been extensively documented here and the final report from the Malaysia / Indonesia component of this research was released earlier this year...

Summary
"Biochar is the charcoal product obtained when biomass (preferably organic waste, not wood) is heated without access to oxygen (pyrolysis). Most of the biochar matrix is likely stable when mixed into soils, and thus represents carbon that is actively removed from the short-lived carbon cycle and thus contributes to climate change mitigation. Biochar combines a number of important “wins” such as: i) climate change mitigation: carbon sequestration and reduction of other GHG emissions (mainly N 2 O), ii) soil fertility improvement, iii) pollutant immobilization, iv) waste management and v) energy production. In this project we investigated two of these “wins” in an Indonesian /Malaysian context: soil fertility improvement and biochar technology /energy production. In addition, physical and chemical properties of biochar were evaluated.

General findings: Co-synthesis of toxic polycyclic aromatic hydrocarbons (PAH) during biochar production has oft en been reported as a potential impediment to biochar implementation. We found however, that for 60 biochars, PAH contents were low and so strongly bound that they were almost unavailable for uptake in plants and soil organisms. We also investigated potential undesired co-effects of biochar on soil biota in a biochar-soil system, and found that these were modest. In addition, earthworms preferred biochar over other soil amendments (activated carbon and an iron-based metal sorbent) in avoidance tests. 

Soil fertility improvement: In pot trials in Kalimantan, (Indonesia) hardly any biochar eff ect on rice and maize growth was found for acid sulphate and peat soils. In contrast, positive biochar eff ects were seen for clay soil in West-Timor and oxisol in Sulawesi (both Indonesia). 

Biochar technology: An upscale Belonio top-lit updraft gasifier was developed and used to prepare biochar for field trial applications in Malaysia. In Sulawesi clean cooking stoves run on biochar generated by improved retort kilns were implemented.

Life-cycle and cost-benefit analysis: these analyses were centered around our case study in the village of Ngata Toro in Sulawesi. The most important finding of both these analyses was that soil amendment for improved soil fertility is a better way to use biochar than burning it as briquettes for cooking purposes. The main reasons are that i) polluting gases generated during biochar production are not off set by carbon sequestration in the briquetting alternative, and ii) briquetting is much more labor-intensive than applying biochar to agricultural soil. 


This research project has paved the way for large-scale implementation of biochar in Indonesia. The biochar will be prepared using environmentally-friendly retort kilns, and mainly applied to degraded lands where yield increases can be expected.

In addition, this project has led to several spinoff projects in other countries: Nepal (biochar from an ubiquitous weed, spontaneous farmer adoption), Zambia (maize biochar in conservation farming), Tanzania (rice husk biochar used as soil amendment, made in retort kilns where energy is used for bread baking by housewife groups) and Uganda (village electrifi cation by gasification with biochar as by-product)."

Bandar Utama — a history of biochar application in Malaysia

The December issue of the IBI monthly newsletter has now been released. It profiles an article that I've written with Dr Francis Ng, on his biochar work at Bandar Utama township, KL, Malaysia over the past 12 years.

A direct link to the profile on the IBI website is here.

This is a slightly edited version of the original article. If you like to read the original, then please scroll down to my earlier release via google docs.

Symphony of the Soil




"The 68th UN General Assembly declared 2015 the International Year of Soils. The Food and Agriculture Organization of the United Nations has been nominated to implement the International Year of the Soils (IYS) 2015, within the framework of the Global Soil Partnership and in collaboration with Governments and the secretariat of the United Nations Convention to Combat Desertification.

To help celebrate the International Year of the Soils, we will be streaming the full feature film, Symphony of the Soil, for FREE for the week of December 5 – 12, 2014. You can help us spread the word by linking to or embedding the film on your site with a link to the Symphony of the Soil website and to the International Year of the Soils."

Biochar animations from Europe

A couple of new 3min. animations on biochar from ...
which I had not heard of and appears to be a European Development Agency initiative.
Its a pity they don't delve a little deeper into productions methods. The animation implies flash pyrolysis production is THE method of production... a bit misleading IMO. They do cover some of the new ideas for biochar applications such as animal feeds and building materials.

News from UniKL MICET biochar group

The following announcement has been provided by Prof. Robert Bachmann for the November IBI newsletter:

At present two undergraduate students under the supervision of Dr Amelia Md Som (
investigate the effect of biochar on phytoremediation of soils contaminated with Cu, Ni, Pb  and  Zn by Helianthus annuus L, while another student, Ms Syila investigates the possibility of using the original Belonio rice husk gasifier for empty fruit bunch. This project is under the supervision of Mdm Asimi Ana Ahmad.
MICET also welcomed two visiting students from Wismar University / Germany, Mr Kevin Busack and Lukas Sievert, who are both recipients of the DAAD RISE Worldwide scholarship (https://www.daad.de/rise-weltweit/en/). Kevin has been given the task to develop a standard operating procedure for APL's biochar experimenter kit (BEK), produce and characterise biochar from oil palm biomass under various process conditions and determine the emission factors for various gases. His project is carried out in collaboration with the Malaysian Palm Oil Board (MPOB). Lukas' challenge is to improve the upscaled Belonio rice husk gasifier developed by Dr Nsamba Hussein Kisiki in terms of ease of use as well as utilisation of the syngas produced.
