Update: 20 February 2014: Employing Aliens to Capture Carbon

See this recently published article by the Green Times highlighting our journey thus far towards creating bona fide Biochar from invasive alien plant species:


Update: 23 December 2013: New Biochar Crowdfunding portal launched

Please support our Crowdfunding project in South Africa. In a nutshell, the project aims to uplift rural youth and women by creating jobs and skills whilst at the same time clearing Invasive Alien Plant Species (IAPs) and reducing global warming.

The Energy and Environment Partnership fund for Southern and East Africa (EEP-S&EA) have kindly stood up and agreed to fund 50% of the Project Management fees, Site Preparation, Tools and equipment and Administration fees. The EEP Programme in Southern and East Africa is jointly funded by the Ministry of Foreign Affairs of Finland (lead donor), The Austrian Development Agency (ADA) and the UK’s Department for International Development (DFID). For further information:


The project actually has many outcomes, but the primary goals are:

Create Employment – Up to 30 workers will be employed in year one. Unemployment is rife (>50%) in the rural areas of KwaZulu-Natal especially with a minimum wage now being introduced for farm workers. The feedstock for the Biochar project will be secured by ‘Vuthisa Charcoal Projects’ through a contract signed with the Department of Environmental Affairs, Natural Resource Management Programme, that pays the wages of our workers.

Eradicate Invasive Alien Plant Species and restore the Natural Biodiversity of the land – We intend to clear over 300 hectares of Wattle in this area and restore the land back to virgin grassland. The main culprit being Acacia mearnsii (Black Wattle) and Acacia decurrens (Green Wattle). Unmanaged Wattles in KwaZulu-Natal has now reached more than 300,000 hectares in extent, according to the Agricultural Research Council (ARC) report commissioned by Water Affairs, 2010. Left untouched, this alien vegetation would spread at an average rate of one percent a year, threatening water and food security. Concerted efforts are being made to prevent the further spread of these invasives especially in water catchment areas, but it is estimated that R 34 Billion ($ 3.4 Billion) will have to be made available over the next 25 years to stop this spread.

Increase Water Runoff in water catchment areas and reduce erosion – The Wattle trees spreads vigorously through the seed it puts out and these typically germinate in river systems, sucking up water and causing stream flow reductions.

Develop Emission Reducing Biochar Kilns and Biochar products and reduce greenhouse gas emissionsAcacia mearnsii is a hardwood species and makes excellent charcoal. Conventional pyrolysing tecnologies in South Africa however are less than 20% efficient. Our first goal is to achieve a minimum of 25% wood to biochar conversion efficiency. Using more efficient methods to produce charcoal (or Biochar) has the potential to save about 100 MtCO2 per year in Sub-Saharan Africa (See CO2 production from Emission Reducing kilns has not been quantified, but a 5 to 10% reduction in GHG’s is expected. We plan to produce 150 tons of Biochar in the next two years and we expect that 20% of this will be bought indirectly by fertiliser companies which could result in at least 30 tons of carbon being sequestered back into the soil.

Update: 13 August 2013: VermiChar eco-fertilizers, A DIY concept for subsistence agriculture


We are happy to announce that our project has been selected for the highly acclaimed First National Bank ‘Ideas can Help’ campaign. The focus of this project is on the subsistence farmer and how they can improve their crops and soil, break the chemical fertilizer loop and produce a high value product merely by using his crop residuals. The goal is to move them up to being sustainable farmers.

If you feel this is a project worth supporting please vote for our concept proposal. I think there are a lot of claims being made about the benefits of biochar to the soil, but only once this can be substantiated with plant trials can we make any kind of claims. If we get the support we hope to get we could end up in the top 3 and qualify for assistance to take the idea further. Please vote to keep us in the running.

To be able to vote you have to register or if you have a Facebook, Twitter or LinkedIn account you can login straight away and cast your vote. After logging in you will receive ‘smiles’ and then clicking on VermiChar and sharing it will earn you more smiles. Use these smiles to cast even more votes for our idea.

Kindly log in weekly to earn more smiles. Sharing our idea will earn you 3 smiles every time you share. We have estimated that if everyone logs in and share our idea only once per week that we could get an additional 45 smiles from everyone until voting stops on 15 October. At this rate we need at least 800 people to vote weekly for us to win the competition.

Vote here: and share on Social Media.

Update: 5 March 2012: Vuthisa becomes partner number 568 in the Partnership for Clean Indoor Air (PCIA).

The Partnership for Clean Indoor Air (PCIA) was launched at the World Summit on Sustainable Development in Johannesburg in September 2002 to address the increased environmental health risk faced by three billion people who burn traditional biomass fuels indoors for cooking and heating. This voluntary Partnership brings together governments, public and private organizations, multilateral institutions, industry, and others to increase the use of affordable, reliable, clean, efficient, and safe home cooking and heating practices. The mission of the Partnership for Clean Indoor Air is to improve health, livelihood and quality of life by reducing exposure to air pollution, primarily among women and children, from household energy use. See our PCIA profile here:

Update: 1 December 2011

Vuthisa have secured a contract with a private farm owner in the Kokstad area (Kwazulu-Natal, South Africa) to remove all the invasive alien species (and poison the stumps to prevent recurrence) on their farm and rehabilitate the area back to grassland. The felling program commenced in October and we have begun to make charcoal from the now dry timber. There are approximately 800 tons of jungle timber that needs to be converted to charcoal and firewood. Only about 50 tons of timber is suitable for the paper pulp market, but because of the steepness of the terrain, short-haul transport options are severely limited. Visit the Contact Us page to get more information.

Update: 30 November 2011

Update: 1 September 2011

We are pleased to announce that The Elizabeth Glaser Pediatric Aids Foundation decided to donate 40 of our StoveTec stoves to the Thandanani Childrens Foundation. The Elizabeth Glaser Pediatrics Aids Foundation has been supporting HIV and AIDS prevention, care and treatment services in South Africa since 2000. Founded in 1989, Thandanani Children’s Foundation is a registered non-profit organisation that facilitates community based care and support for orphans and other vulnerable children in the KwaZulu-Natal Midlands (South Africa). A wonderful gesture to a worthy cause!

We have re-launched our website with our new logo, in which we highlight Emerging Energy / Green Technology products that don’t typically find their way to your local retail outlet. The products are quite diverse yet all find relevance in an off-grid environment and include cooking stoves, solar cookers, a novel water roller, hand operated fuel briquette presses, charcoal making kilns and books for development workers. We also offer our own in-house range of services, namely Farm or Plantation Mapping, Geo-modeling and 3D modeling.

Update: 17 April 2011

Vuthisa has successfully installed 90 StoveTec wood-burning stove in a village near Ixopo, KwaZulu-Natal.

The farm owner is looking forward to seeing a reduction in his firewood collection and handling costs because the StoveTec stove uses 50% less fuel than other stoves on the market. The recipients of the new stoves are all extremely pleased with their new stoves and at our recent visit to them we had absolutely no negative comments or complaints about the StoveTec. Their homes are less smoky now, they use less wood and they are able to cook their food faster. A win-win situation for everybody involved.

The usually loose standing stoves are cemented into custom-made docking stations to serve as 2-pot or 3-pot stoves. Above each station is a hood that collects the emissions and channels it towards the chimney. The stoves are operated with just a few sticks of wood and will only occasionally give off smoke, such as when started up or when adding new wood.

This particular village is connected to the electricity grid but the management company had no option but to leave it offline and revert to using wood in light of the annual electricity hikes imposed by Eskom. Go to the installations page for the full article.

Update: 20 December 2010

The Journal of the International Energy Initiative, Volume 14, no.3, recently published (September, 2010) “Field testing and survey evaluation of household biomass cookstoves in rural sub-Saharan Africa” by Edwin Adkins, Erika Tyler, Jin Wang, David Siriri, Vijay Modi of Columbia University, New York, NY, USA. The conclusion reached was that the StoveTec stove was voted the best stove by the participants of the study in both Uganda and Tanzania…

Field testing and survey evaluation of household biomass cookstoves in rural sub-Saharan Africa


“This paper presents the results of two studies conducted to evaluate the performance and usability of household biomass cookstoves under field conditions in rural sub-Saharan Africa. Cooking tests and qualitative surveys compared improved, manufactured stove models based on the ‘rocket’ design with the traditional three-stone fire. All tests and interviews took place in household kitchens in two village areas in Western Uganda and Western Tanzania…”


“The fuel saving benefits of the improved stoves were generally clear and quantifiable, and, the imported stoves were seen as preferable to the threestone fire. The StoveTec performed the best overall, with substantial fuelwood savings for all cooking tests and high user rankings in both studies. Though the other three stoves were not compared directly against one another, results suggest that the Envirofit stove ranked second, overall, while the two locally-made stoves were ranked lower, in one case below the three-stone fire.”

Update: 3 December 2010

Vuthisa is announced as the StoveTec Dealer of the month (December) by the StoveTec Importer in South Africa. This is what the importer had to say:

“Congratulations to Kobus Venter, our Retailer of the Month for December. Kobus was one of Restio’s first agents for the award-winning StoveTec stoves. He has been active in setting up rural entrepreneurs for the stoves in-and-around Pietermaritzburg – liaising with local municipalities, hosting training workshops, exhibiting the stoves at a number of expos and festivals, etc. This month, Kobus attended a ‘fuel briquette producers workshop’ in Arusha (Tanzania) where he spoke about combustion issues and the wonders of the StoveTec stove.

Kindly refer to Kobus’ blog to read more about the workshop and view some fantastic photos: Your free StoveTec stove will be included in your next order. Keep up the inspiring work, Kobus!”

Update: 31 March 2010

Vuthisa has partnered up with Thandanani Children’s Foundation in supplying low-cost cooking stoves to poor households in the Pietermaritzburg and Richmond areas of KwaZulu-Natal. Thandanani has a network of volunteers that provide care and support for families with orphans and vulnerable children, households identified as being in dire need of emergency assistance, facilitating access to fee remissions, social grants and other forms of government support, facilitating the establishment of volunteer driven income-generating projects, to name but just a few of the services they offer.

The volunteers, as their name imply, volunteer their own time and travel expense to visit above families in question for very little remuneration. We wanted to know whether or not the volunteers would be interested in signing up as sales agents as an incentive to get word out about the remarkable StoveTec wood stove, so we arranged cooking demonstrations. The feedback we received was very encouraging and many are interested in taking delivery of demonstration stoves in order to give demonstrations in their own respective areas.
