Seeing the wood for the
trees in Uganda
Ugandan social
enterprise Eco Fuel Africa (EFA) has come up with an innovative method for
turning agricultural waste into clean biomass energy, leading the way on how to
cope with emissions and rampant deforestation from wood fuel usage in this
agriculturally dependent East African nation.
EFA uses coffee husks, corn cobs, ground nut
shells, sugarcane waste, and rice husks to make clean and affordable
briquettes. The briquettes are a carbon-neutral cooking fuel that functions the
same as wood fuel, but is highly efficient, cleaner, smokeless, and burns longer.
They address one of the largest causes of emissions and deforestation, while
also improving household health in Uganda.
“I got the idea of
making briquettes when I visited my home village in rural western Uganda and
found that my sister had missed school because she had to walk long distances
to collect firewood,” says Moses Sanga, the director of EFA. “The trees that
surrounded our home were gone, and she had to walk longer distances to gather
firewood. I had to find a solution.” But this was not the only thing Sanga
noticed in his hometown. “There was plenty of litter everywhere,” he says.
“Uganda is primarily agricultural, but farm waste is just abandoned.” It was
then that Sanga began researching and learning everything he could about
turning organic agricultural waste into fuel.
Armed with a bachelor’s
degree in finance and with the help of engineering students from Makerere,
Uganda’s leading university, he embarked on a mission to design kilns and
briquetting machines using oil drums. This led to the founding of EFA in April
2010.
How
it happens
The locally-made kilns
carbonise agricultural waste to create char. The briquetting machines use high
pressures to mould loose char into compact and solid fuel briquettes that can
be used for cooking, boiling water, or heating rooms. EFA provides training to marginalized
rural farmers on how to turn their agricultural waste into char.
After the training,
they are offered a chance to take home a kiln on a lease-to-own basis. “We are
currently working with 3,500 farmers who use our kilns,” says Sanga. “About 80%
of the produced char is sold directly to EFA and each farmer earns at least $30
(€26.8) per month in additional income.
EFA then presses the char into cleanburning fuel briquettes.” The farmers are also trained on how to mix the biochar with local organic nutrients to make fertiliser, which they then put in their gardens. This has helped them increase their food harvests by more than 50% ensuring food security and reduced malnutrition. EFA also works with a network of female micro retailers that sell the briquettes to end-user customers. Selected women are trained for three days and at the end of the training, EFA builds each of them a kiosk to use as a retail shop to sell briquettes in their local communities. Already, EFA has created a network of 2,000 female retailers in Uganda. Each of these women retailers earns at least $152 per month. “By using agricultural waste, we are creating clean, affordable and accessible energy, helping to create socially and economically thriving communities,” says Sanga.

EFA currently provides
fuel for more than 115,000 Ugandan families and is responsible for saving
500,000 acres of forests in averted deforestation. It also sells its products
to institutions like schools, hospitals, hotels, and restaurants. “Our goal is
to provide clean cooking fuel to every energy-poor household in Uganda by 2020
and a 150,000 tonne reduction in CO2 emissionsper year,” Sanga concludes.
Another company helping Ugandans embrace clean energy is Pamoja Cleantech, also
specialising in waste-toenergy projects. It converts waste products into high
energy density fuel pellets for industrial and domestic use. The firm also
makes energy-efficient cooking stoves and operates microgrids powered by
biomass fuels for direct electricity distribution in rural areas.
Government
support
The government of
Uganda has long regarded biomass energy as a viable option for clean energy
generation. Uganda’s Renewable Energy Policy was put in place to increase the
share of renewable energy in the energy mix from the current 4% to 61% of the
total energy consumption by 2017. The policy recognises biomass as a
significant source of modern, clean forms of energy with potential to
contribute to Uganda’s energy sector development. The government has also put
in place a legal and institutional framework to attract private investments in
development of modern energy forms. This includes the introduction of specific
tax regimes that favour modern energy, such as preferential tax treatment and
tax exemption. According to statistics from the Ministry of Energy and Mineral
Development, Uganda’s energy consumption matrix currently stands at 90%
biomass, 7% petroleum products, and 2% electricity produced from hydro and
thermal power plants. The majority of the population relies on wood based fuels
in forms of firewood and charcoal as a main source of energy for cooking. This
has led to massive environmental degradation and health hazards among
households. According to the Uganda Demographic Health Survey (2006), cooking
with wood fuel is a major cause of respiratory illnesses such as lung cancer
among Ugandans, given that it emits a lot of smoke and affects the quality of
air in a household. Worse still, using biomass hugely depends on traditional
technologies such as three-stone fireplaces and charcoal stoves that are quite
inefficient in their fuel utilisation, leading to excessive use and demand for
firewood.
According to Godfrey
Ndawula, the Commissioner of Renewable Energy in the Ministry of Energy and
Mineral Development, 18 million tonnes of firewood is burned every year,
resulting in deforestation on a massive scale. “EFA will help us save our
forests and avert the 13,000 reported premature deaths resulting from indoor air
pollution,” he says.
‘Need to raise awareness’
Despite its important
economic and social role, uptake of modern biomass energy is still low in
Uganda. According to a Ministry of Energy report on Uganda’s biomass energy
situation, the country’s main challenge is not the supply of biomass but rather
lack of awareness among the masses on modern forms biomass energy and lack of
the appropriate technologies. Therefore, there is a need for intensive
promotion and marketing both in urban and rural areas to increase uptake of
modern biomass energy alternatives. “We need to raise awareness of the new
improved biomass energy and environmentally-friendly cook stoves to reduce
firewood consumption and global emissions,” Ndawula says. Biomass energy is
also yet to receive recognition and prioritisation in terms of funding from
government compared to other renewables such as hydro energy, which impedes its
development. Uganda typically generates almost half of its modern energy output
from hydropower dams along the River Nile.
The micro-scale social enterprises that form the bulk of investment in the biomass energy subsector face a number of challenges, including maintaining appropriate financial and human resources to sustain operations, and cannot afford market development costs. Traditional financing through commercial banks or commercial lending institutions has not been a viable option for many of these enterprises. The inability to predict monthly sales, the lack of collateral and credit history, and the large informal economy mean that commercial banks hesitate to provide loans to businesses.
However, the Ugandan government has established the Uganda Energy Credit Capitalization Company (UECCC) to assist micro-project developers interested in doing business in the biomass energy subsector in Uganda in attaining financial closure. Social enterprises are also looking to take advantage of the green climate fund and carbon financing in order to acquire funds and engage in product marketing and promotion, to help rural communities. “If biomass waste-to-energy projects are scaled up, it could allow rural Ugandans to embrace cleaner cooking methods that protect the environment,” says Ronald Kaggwa, an environmental economist at the Uganda National Environmental Management Authority. He adds: “If the country could turn more of its waste into energy, it would also bring it closer to its goals of switching to greener energy sources and reducing deforestation.”

According to Lighting
Africa, a World Bank group programme to increase access to clean sources of
energy, Africa has a large off-grid population. More than 590 million people
live with no connection to their national electricity grid, exposing them to
hazardous options. This is an indicator that biomass will continuously play an
important role in Africa’s energy sector. Investment in efficient, clean and
less polluting modern biomass energy should be a priority if Africa’s emissions
are to be curbed and forest cover conserved.
