New bamboo charcoal technology promises to jump-start Africa’s bio-energy sector

Bamboo, a plant not often associated with Africa due to it not exploited, may be the key to combating soil degradation and massive deforestation on the continent. The plant can be used as an alternative source of energy.

A partnership among African nations and communities, the International Network for Bamboo and Rattan (INBAR) and China are working to substitute bamboo charcoal and firewood for forest wood on which 80 percent of the rural population in sub-Saharan Africa depend for their fuel needs.

Initial successes with bamboo charcoal in Ghana and Ethiopia, which have put bamboo biomass at the centre of renewable energy policies, are spurring interest in countries across the continent and prompting calls for greater investment in bamboo-based charcoal production as a ‘green biofuel’ that could fight deforestation and mitigate climate change.

“Bamboo, the perfect biomass grass, grows naturally across Africa and presents a viable, cleaner and sustainable alternative to wood fuel,” said Dr. J. CoosjeHoogendoorn, Director General of INBAR.

“Without such an alternative, wood charcoal would remain the primary household energy source for decades to come with disastrous consequences,” he said.

Scientifically, burning wood also has a significant impact on the climate. Scientists predict that the burning of wood fuel by African households would release the equivalent of 6.7 billion tonnes of greenhouse gases into the atmosphere by 2050.

In terms of health, the burning of fuel wood claims the lives of an estimated 2 million people every year mostly women and children who inhale the smoke, according to data from INBAR. Continued widespread indoor use of forest wood charcoal as a household fuel could cause 10 million premature deaths by 2030.

INBAR’s bamboo as sustainable biomass energy initiative is the first to transfer bamboo charcoal technologies from China to sub-Saharan Africa to produce sustainable ‘green biofuels’ using locally available bamboo resources.

Driven by growing concerns about energy, health and food security and climate change, the initiative is funded by the European Union (EU) and the Common Fund for Commodities (CFC).

Saving Forests, Mitigating Climate Change

It takes seven to 10 tons of raw wood to produce one ton of wood charcoal, making wood fuel collection an important driver of deforestation on a continent of nearly one billion people, who have few alternative fuel sources.

“Ensuring food security in a changing climate is one of the major challenges of our era. It is well known that the destruction of forests has negative repercussions on livelihoods and sustainable agriculture as it feeds into a cycle of climate change, drought and poverty,” said  Dr. Patrick Verkooijen, Head Agriculture and Climate Change of the World Bank. “Feeding people in decades to come would require ingenuity and innovation to produce more food on less land in more sustainable ways”.

Indeed, scientists believe that deforestation across the Horn of Africa has contributed to pervasive drought in the region.

Years of tree-clearing, particularly in hard-hit Somalia, has eliminated fragile forests that stood as the last line of defense against the conversion of sparsely forested dry lands and pastures into useless desert, according to researchers from the Consultative Group on International Agricultural Research (CGIAR).

The International Energy Agency (IEA) predicts that if business continues as usual, by 2030 biomass energy in sub-Saharan Africa would still account for about three-quarters of total residential energy, underscoring the urgency of coming up with a sustainable alternative biomass to replace wood.

Sub-Saharan Africa has over 2.75 million hectares of bamboo forest, equivalent to roughly 4 per cent of the continent’s total forest cover.

“Rural communities need access to sustainable approaches that will keep trees in the ground and the environment safe,” said Professor Karanja M. Njoroge, Executive Director, Green Belt Movement.

“Bamboo grows naturally across Africa’s diverse landscapes, but unlike trees, it regrows after harvest and lends itself very well for energy plantations on degraded lands. We should put it to good use to provide clean energy for the continent.”

“With further investment and policy reform, community kiln technologies could be up-scaled to reach thousands of communities in Ethiopia,” said MelakuTadesse, National Coordinator for Climate Change Unit at Ethiopia’s Ministry of Agriculture.

He said a number of African countries are pressing for development of their own bamboo charcoal industries to provide sustainable, affordable energy for their growing populations.

Harnessing the Perfect Biomass Grass

Bamboo is one of the fastest-growing plants on the planet and produces large amounts of biomass, making it an ideal energy source. Tropical bamboos could be harvested after three years, compared to the two to six decades needed to generate a timber forest.

Indeed, the entire bamboo plant, including the stem, branch and its rhizome, could be used to produce charcoal, making it highly resource-efficient, with limited wastage. Its high heating value also makes it an efficient fuel.

Its charcoal is made through the controlled burning of bamboo in kilns, whether traditional, metal, or brick.

The technology is being adapted to produce larger quantities of charcoal to serve a larger number of rural and urban communities as well as to produce bamboo charcoal briquettes that are ideal for cooking because it burns longer, produces less smoke and air pollution than ‘natural’ charcoal.

China is a global leader in the production and use of bamboo charcoal. The sector is worth an estimated  $1 billion a year and employs over 60,000 people in more than 1,000 businesses.

Chinese partners, including the Nanjing Forestry University and WENZHAO Bamboo Charcoal Company, are helping to adapt equipment like brick kilns, grinders and briquette machines, and hand tools, for bamboo charcoal and briquette production using local materials.

Building on this momentum, the INBAR initiative is now transferring China’s advanced bamboo charcoal technologies, which focuses on providing cleaner, safer “Green” energy source, to sub-Saharan Africa.

In addition to charcoal, bamboo offers many new opportunities for income generation.  It is being processed into a vast range of wood products, from floorboards to furniture and from charcoal to edible shoots.

The world bamboo export was estimated at 1.6 USD billion in 2009, a decline of about 659 USD million from 2.2 USD billion 2008.

Progress in Domesticating Bamboo Technology in Ghana

Currently the ”Bamboo as sustainable biomass energy, a suitable alternative for firewood and charcoal production in Africa” is being implemented in Daboase and Tandan in the MpohoorWassa East and Ellembelle Districts respectively in the Western Region of Ghana.

It is being funded by the European Union with an amount of 1.663 million Euros of which INBAR is providing 20% of the budget cost.

Key partners to the project are the Forestry Research Institute of Ghana (FORIG) and Bamboo and Rattan Development Programme under the Ministry of Lands and Natural resources. Associate partners include the Energy Commission and Chemical Engineering Department at KNUST.

So far, 300 micro small enterprises (MSE) in the catchment area has been established with over 2,000 out growers cultivating bamboo as well as charcoal production and some 7,000 low income local households are expected to use bamboo charcoal as fuel wood by the close of the project year in 2014.

A total of 505 tonnes of bamboo charcoal have been produced for October and November 2011.

Conscious efforts of cultivating bamboo have seen the planting of 11,733 seedlings out of 14,880 seedlings propagated from 15 different species selected across the globe.

By statistics, a disconsolate situation about rate of forest depletion makes the bamboo technology a welcome concept as the country had lost about 6.6 million hectares of forest cover since the beginning of the last century and having the highest rate of deforestation of 2.19 percent globally.

New Bamboo Charcoal Technologies Promise to Jump-start Africa’s Bioenergy Sector, and holds the key to slow deforestation and fight Climate Change at the same time.

It is envisaged that Africa’s leadership, policy-makers, private sector, Metropolitan, Municipal and District Assemblies, Religious and Traditional Authorities as well as civil society organisations would lead the crusade towards saving the forests and the environment from vicious abuses.

Ghana plays host to the next global Regional Steering Committee meeting in the Western Regional capital, Takoradi, in February, 2012, according to Mr Michael Kwaku, West African Coordinator of INBAR.

    Ghanaians apreciate the effort being made by INBAR and its partners to slow down deforestation and fight against climate change.

  2. Adu Agyare Kwabi says

    The technology seems laudable but the resources and the equipments to be used for the production process would be a hindrance.Something serious must be done about the situation if the attempt to fight deforestation is going to succeed.I am interested in going into such a venture.

  3. Teddy says

    use of improved cookstoves is the first small step, growing and processing woody biomass is the big leap.
    innovative measures should be taken, if aerial seeding is working out in China for re-planting 1000’s of hectors of forest, perhaps every time a pop-star, politician or AID group fly’s somewhere in Africa, they should be required to drop out tree seeds as they go. some of the tree seeds will grow.

    It is a nice article informing us about bamboo charcoal but i would rather much have read more about the Ghana project in Daboase and Tandan. So many questions are ringing in mind about it. What are the benefits- where are the local voices? Mr. Kwaku should say more in the story instead of the WB officials. Which are the policies that Ghana has established to have this as a success? Explain a bit more about the science or the technology used. Keep it short, it is too long.
    I will be glad to read an article after the conference.

    @ Esta, I am a Dutch student in Sustainable Development. From April-August 2011 I was fortunate to do my MSc research with INBAR Ghana on the opportunities of using bamboo biomass energy for Forest Landscape Restoration. An important part is based on those “local voices” you talk about.
    If you are interested in the results, I could send you the electronic version of the report, or just the abstract if you wish. Please send a request via a.b.bos[at]

  6. JOHN YEBOAH says

    This project is very laudable. I once researched into the socio-economic importance of commercial charcoal production in an area of Brong Ahafo Region of Ghana and was amazed at my findings. An alternative to natural forests for wood fuel will be wonderful development for Ghana. What about quick growing bamboo species.
