The Briquette production at Green Heat Uganda Ltd depended on weather conditions because sun is key in our drying processes. Frequent downpours during rainy seasons cut the production to half of its capacity. Since moisture content is a quality characteristic of briquettes, it has to be reduced from 50 % to below 10 % before sale. Thus the dependency on weather conditions meant a financial risk to the company. Considered as one of the cheapest drying options, CREEC recommended the use of a solar dryer. Only very few commercial solar dryers are used in Uganda. Furthermore, there is virtually no local market comprising of solar dryer businesses. To support the commercial use of solar dryers in Uganda, we have implemented a demonstration project at Green Heat Uganda Ltd with generous support from Afri Banana Products.
- to make a simplified designing scheme available and enabling local fabricating.
- identify crucial parameters to improve the draft.
- analyze implementation and operational cost of the solar dryer at Green Heat Uganda Ltd through evaluation of costs, efficiency compared to other technologies such as electric dryers.
We at Green Heat hope that the solar dryer will allow increased turnover with simultaneous improvement of product quality and reliability of the production process.
Green Heat is implementing and facilitating biogas installation for the Afri-Flame Network, a team of Agriculture, Soil Science and Renewable Energy researchers and developers from Universities, Institutes and technology companies in Uganda, Cameroon, Ethiopia and Scotland. The consortium has received a grant from the African Union to set up biogas digesters and fuel saving stoves in ‘Energy Villages’ in Uganda, Ethiopia and Cameroon.
Biogas technology provides clean gas for cooking and lighting, makes effective use of food and other organic waste and animal manures to produce a nutrient rich fertilizer for farming.
Biogas digester technology is spreading fast in Asia but uptake in Sub-Saharan Africa has so far been slow, despite significant national and international efforts to support technology adoption. The reasons for the slow adoption rate are poorly understood. It is unclear whether this is due to low demand or due to other socio-cultural barriers that prevent uptake. There is a pressing need to better understand what drives demand for biogas technology and to identify facilitating and inhibiting conditions for uptake. This will provide policy makers and promoters of biogas technology with invaluable information for the development of the economic measures and technical tools needed to enhance technology uptake.
Green Heat is responsible for installation of household digester, sourcing of micro gasifers stoves, hands-on training (farmers) and facilitate in workshops. We are also holding regular briefings and one-to-one meetings with farmers to ensure technology is understood and acceptable, maximising performance and troubleshooting problems.
A major aim of this 3-year project is to research and publish technical and social science on the practicality of biogas and fuel saving technologies in rural households in Africa.
P.S. Vianney Tumwesige is a PhD student registered at University of Aberdeen, he will work on this project.

Briquettes are a viable and low cost alternative to environmentally damaging fuels such as firewood, kerosene and charcoal. They are similar in appearance to regular charcoal but they are made out of charcoal waste, agricultural residues or sawdust, which are normally considered unusable waste.
We also took part in this year’s Energy Exhibition at the National Theatre, this is part of our annual activities . It was a great experience, we thanks all the visitors and potential clients who spared time to chat with Green Heat Team.
