The pyrolysis project with cook stoves for Burkina Faso was initiated in the name of the German NGO Welthungerhilfe. The targets were in specific the reduction of deforestation through using the leftover from harvesting, increase the energy efficiency of the cook stoves, improve the soil fertility via terra preta and last but not least the reduction of respiratory systems affections. The reduction of smoke gas and the gain of biochar is an overall goal to reduce CO2 emissions and energy costs to safe the families money for their daily life issues. Creating a new local economy cycle with new jobs in the energy sector, the agricultural sector and in sanitation.
The aim of the project is to empower local companies to convert residual biomass to highly compressed fuel in the form of pellets or briquettes. The pellets are natural and highly efficient fuel for cooking stoves. These stoves use the principle of pyrolysis and create biochar as a byproduct. By using biochar as a basic technology for pollution prevention and for nutrient recovery substrates there can is also an improvement on the soil. The tasks of the project include securing a range of fuels in the form of briquettes or pellets, to provide a sufficient range of the typical family households suitable pyrolysis furnaces and the implementation of Terra Preta technologies for sanitation and climate farming.
A local employee of climate farming, Sara Maiga, had founded Climate Sol – a charitable foundation – to train and instruct the population in the new combustion technology. As a parallel process to the implementation of the cook stove, a distribution network for pellets has been build up by Sara Maiga. After a trade fair for renewable energies in Ouagadougou in 2015, about 50 stoves were distributed to families in the capital.
Promoted by the Bingo Environment Foundation from Federal State of Niedersachen/Germany, the non profit organization Lernen–Helfen–Leben e.V. has financed the introduction of 300 pyrolysis furnaces in cooperation with Climate Sol in urban households and restaurants in Ouagadougou. The pilot project in Burkina Faso replaces the traditional cook stoves, and reduces the consumption of carbon or wood from logging. The highly efficient climate stove was invented by Jörg Fingas from Technical University Hamburg-Harburg. The furnace allows for a regulated smokeless flame and achieves CO2 emissions comparable to gas based stoves. The stove received a certificate by the Technology Consultancy Centre of the College of Engineering of Kwame Nkrumah University of Science and Technology in Ghana, a partner of the Global Alliance for Clean Cookstoves. The Bingo project is part of a larger project, to provide proof of a circular climate economy.
The region in the north of Senegal is characterized by extremely degraded soils with a high degree of salt. These soils are exposed to strong wind erosion, with annual losses of up to 50 tons of top soil per hectare. Whilst executing false watering and unmatched handling of fertilizers more than 1/3 of acreage are affected by salinisation. In particular, the overgrazing by goats and search for firewood for cooking prevent the reintroduction of trees. Only the invasive, thorny acacia gum withstands this pressure. Climate farming is working on a research approach to tackle the issue.
Since 2009, the Secretariat for Climate farming is in contact with the rice farm CNT in the rice-valley in the north of Senegal. The company is run by entrepreneur Ibrahima Sall, who was born there and established the company 25 years ago. Approximately 1,000 families each year lease rice paddies with 1-10 ha size and manage them. Ibrahima Sall provides fertilizer, seeds and pesticides to the farmers. 600 ha are managed directly by his company. The owner understands his project as a laboratory for a post-fossil, sustainable circular economy. Therefore he realizes various projects to test and evaluate promising biochar applications into agriculture: the extraction of reeds by the local population, the production of pellets from dried reeds on the farm, the sale of these pellets and their use within the company as a fuel, and the improvement of farmlands with the resulting biochar. For this purpose, among others, Professor Ralf Otterpohl from Technical University Hamburg-Harburg was invited as an international expert for biochar to support on site.
