PROPOSAL: Promotion and Marketing of Biomass Briquettes as Cooking Fuel & Improve Cook-Stoves to Mitigate Deforestation in Tanzania – Green Energy

Space Engineering Company Limited (
Private sector

    Our company (Space Engineering Limited) strength is "WASTE-TO-ENERGY", i.e. conversion of biomass technologies for sustainable development. Problem we are trying solve: (1) Using biomass briquettes as fuel for cooking, instead of charcoal which is unsustainable, (2) Cook-stoves which use briquettes, (3) Mitigation of green-house-gas. Tanzania has about 15 million tons/year of agricultural waste & and 1.8 million tons/year of forest residues which could be easily converted to briquettes as fuel for cooking. Dar es Salaam alone consumes charcoal = 750,000 tons/year of which lead to deforestations of 250,000 – 350,000 hectares/year are destroyed in Tanzania causing environmental degradation. Todate, we currently supply briquettes = 9 tons/day to households = 13,860 every day. We have sold = 6,250 cook-stoves

    Implementation of the Project/Activity

    ACTIVITIES Awareness raising will be encouraged our community by the organization of the following activities: 1. Briquettes factory is installed and commissioned. Successful trial runs to the desired production quantity and the quality of the briquettes 2. The briquettes factory starts production at a rate = 25 tons/day. Smokeless burning of briquettes in the improved cook-stoves leading to 20% - 40% fuel savings. 3. The success will be verified through site visits interviews and bi-monthly monitoring and evaluation reports Activities will include: 1. Promotion and awareness campaigns to educate households on the health hazards associated with household air pollution 2. Large scale dissemination of cook-stoves and demonstrations of the benefits of clean cooking solutions as compared to the traditional stove MONITORING Using a gender equality approach that recognizes the conditions and needs of both men and women, (1) Identifies the possible gender equality challenges and opportunities as part of the project assessment, (2) Highlights the risks and potentially negative impacts of the project on gender equality, (3) Examples of indicators for the monitoring and evaluation of operations in the renewable energy sector. Project will have multiple-benefits: Social, economic and environmental. Women’s and youths empowerment in terms of economical as well as health benefits - emission reductions. The project is funded by TWO sources: 1. In 2019, our company, Space Engineering Company Limited won a grant worth about $88,000 from the government of United Republic of Tanzanian to promote the renewable energy. The funds are still going on facilitating to our company. 2. In 2017 we won grant competition worth $100,000 for project was about renewable energy. The competition was granted by the United States Development Foundation. We use this funds to build the factory we currently own in Kibaha, Dar es Salaam in Tanzania. Similarly, we contribute in-kind for the factory we in Kibaha (Tanzania) where we are currently making biomass briquettes & manufacturing of cook-stoves.


    Providing clean cook-stoves to replace the old inefficient three-stone burning, the aim is to reduce indoor pollution. ACTIVITY ►Consumers switching from the traditionally three-stone which is low-efficient, instead, high burning biomass briquettes as fuel for cooking. ►These cook-stoves are regarded by many to be high-efficient, because of the amount of firewood they require to operate, as well as their relatively low cooking times. ►Given their important intra-household health externalities and the public goods nature of their environmental benefits, there are likely strong rationales for communities to use of briquettes & cook-stoves. GOALS / OUTPUT ►Burning of biomass briquettes in cook-stoves prevents indoor air pollution and other health hazards thereby contributing to MDGs 4 and 5 (reduce child mortality and improve maternal health through reduction of indoor air/smoke related disease like acute respiratory infection affecting mainly newly born and young children and their mothers who are exposed to smoke during cooking and food preparation. ►Goal is been achieved of clean cooking & cook-stoves are to promote the enterprise-driven, large-scale adoption of clean cooking throughout, with the goal to reduce poverty, health-related risks, and adverse environmental impacts.

    Enabling factors and constraints

    - We are constraint because we lack machinery to produce biomass briquettes as fuel for cooking. KEY MACHINERY WE WOULD LIKE TO BUY FROM CHINA 1. COMBINATION CRUSHER - Charcoal double-shaft-mixer = 4 tons/hour 2. DOUBLE-SHAFT-MIXER - Mix charcoal dust + binder + water ready to go to briquetting = 4 tons/hour 3. BRIQUETTE MACHINE - Automatically produce biomass briquettes at a rate 4 tons/hour 4. BRIQUETTES DRYER – Dryer briquettes = 2 tons/hour and they come out on the other end ready to be packed to be taken to our clients Below, the website shows the complete machines which we would like to buy from China.

    Sustainability and replicability

    - These contribute to the community in Tanzania; sustainable development is includes social, economic & environmental benefits. SOCIAL BENEFITS – Create opportunities for increased productivity through burning biomass briquettes in high-efficiency cook-stoves and reduce the time used for cooking or searching for wood-fuel. ECONOMIC BENEFITS – Selling of agricultural wastes, operation and maintenance of the briquettes plant will create employment and reduce poverty. Women and youth will particularly benefit by collecting and selling biomass. ENVIRONMENTAL BENEFITS – Sound and efficient disposal of residues and reduction of green-house-gases by substituting briquettes with charcoal potentially reduce environmental degradation. GOVERNANCE - By involving local communities in business of biomass briquettes factory and supply of biomass, the technology has an outreach impact beyond the mere supply of briquettes. Know-how is built locally and employment is generated.

    COVID-19 Impact

    - The project will deliver numerous sustainable development benefits and will make a tangible contribution to a number of Sustainable Development Goals (SDGs) via reduction of energy poverty (SDG 1), lessening exposure to health risks (SDG 3), reducing drudgery for women in collecting wood fuel (SDG 5), improving access to modern energy (SDG 7), reducing GHG emissions and strengthening communities’ resilience to climate change (SDG 13), and diminishing pressure on forest resources (SDG 15) for 11.4 million people directly during project lifetime and over 30.6 million people indirectly until 2030. Goal is been achieved of clean cooking and improved cook-stoves are to promote the enterprise-driven, large-scale adoption of clean cooking solutions.

    Other beneficiaries

    The target group are the residents of capital city of Dar es Salaam (Tanzania) whose population is 5 million people and consume estimated total 720,000 tons/year of charcoal. Initial target for the proposed project are about 50,000 households/day who will consume 25 tons/day of briquettes. We will purchase license from China for manufacturing of machinery locally in Tanzania. We can establish 80 micro-factories in Dar es Salaam to satisfy the cooking needs. They will use biomass instead which is unstainable charcoal which causes deforestation.
