Teaching Renewable Energies and Sustainability in the School of Diogo Vaz (São Tomé, Africa)

This work aims to show how sustainability and renewable energies could benefit a rural area of Africa (in São Tomé) by means of using solar energy and biogas. Applying these technologies requires ingeniousness and little founding, the favourable outcomes are becoming less dependent of fossil fuels (wood, coal and gasoline) while saving time and, more importantly, the forest. We have taught how to design, build and operate systems for cooking, lighting and water-heating that use renewable sources of energy.

This project will be carried out within the Nile Basin in Western Kenya. The same area is sources of Nile and other small tributaries. The project will promote energy saving culture and lead to sustainable use of forest resources while contributing towards the Kyoto protocol implementation. While noting that firewood is the major source of energy within the Nile basin and Methane, is 20 times more potent CO2 and hence its use in biogas energy is encouraged in managing green house effect.

Western Kenya has a population of over 5 million people of which 80% depend on agriculture for livelihood and over 70% use firewood as fuel source. A survey has shown that all boarding schools use firewood and charcoal as fuel for cooking hence pressure on forest cover. Sugar cane growing in Mumias, Malava and Bungoma is a heavy user of trees as firewood. This combined has led to heavy exploitation of forests and trees for firewood hence a danger to the water catchments area.

Sugar cane cultivation in western Kenya, which started in mid 1970’s, has accelerated the rate of destruction of trees due to high population density has further compounded the problem of destruction of forests and trees hence threatening the very source of water within the Nile Basin. Schools continue to put pressure on forest due to their high demand for firewood to use in cooking with highly inefficient open fire stoves. These project will develop biogas as an alternative source of energy, promote economical use of energy in institutions and homesteads through use of energy saving stoves create employment for people trained in production and service of the same and of the same and efficiently generate and use the highly potent methane from farmlands through biogas plants.

This project meets the requirements of MDG's and Partnership for clean indoor air broad objective. The project will support community driven effort and will address environmental threats on local scale within the Nile basin region in the area of development and use of alternative energy and construction materials. In the process of carrying out participatory planning and appraisals for Musamba, Matungu, Kholera and Khalaba, the villagers expressed the desire to get cheap alternative to fuel firewood energy and alternative to open fire 3-stone cooking method. In all this areas, villagers expressed their fears that trees are disappearing and as a result they use farm wastes like maize stalks for firewood. The same should be used to replenish soil fertility after the crop season and should not used in the kitchen as firewood. Others were resorting to cane trash and remnants.

At long last a short description with pictures of the kind of stoves on the agenda of Shina Group in corporation with a few members of the Danish Tanzanian Friendship Association ( I hope this will do for initial comments and ideas. The aim of the project is as in many developing countries to reduce the use of firewood and minimize smoke in the kitchen thereby improving the health of the cook and her children. We shall be most pleased to receive advice and ideas.

BP Arivi

BP has taken a life-cycle approach, starting with the consumer need, through to regulatory and HSE assessment in the case of BP Arivi. BP Arivi is a low-sulphur paraffin fuel for domestic cooking, providing consumers with access to an affordable, high-value fuel, in safe and child-resistant packaging. Different options were considered to determine the most appropriate fuel to meet the needs of consumers and scrutiny of the supply chain was undertaken to identify key risks We are now commercially piloting this solution in the market in South Africa and there will be further iterations around the process.

Hello stoves community,

At ETHOS 2009 we held a panel on stove safety, bringing in viewpoints from corporate standards development, national standards certification, and small to medium scale developers. The team led by Nathan Johnson (Iowa State University) included Crispin Pemberton-Pigott (New Dawn Engineering), Casper Thijssen (Philips), and Karabi Dutta.

The panel gave a comparative analysis of how different stove industries (multinational corporations, medium-scale companies, NGOs, small developers, etc.) addressed fundamental stove safety questions. These topics included:

a) applicability of standards and regulation;
b) incentives and benefits
c) facilities and equipment availability
d) cost vs. benefit
e) resulting action

We determined that each type of industry has a different perspective that influences their path or actions towards a safer stove. And that all sub-industries may not produce safer stoves given the same incentive mechanisms or policies. As such more than one path to safety may be needed to reach the greatest amount of end-users (and producers). The panel ended the discussion with an overview present work in stove safety with recommendations for next steps.

Please view the attached file for more details. I will be leading a group in 2009 to work on the following: assemble database of injury data, b) analyze incentive mechanisms, cost/ benefit, c) development of lab testing procedures for different stove categories, d) publication of findings/ results, and e) look for partnerships with international agencies to support safer stove design and production.

Please contact me if you have any questions. There will be more updates to follow. Best,

Introducing Greenie©
For a Greenie-er Happier, Healthier Gambia
George Riegg, Paper Recycling Skills Project, Serekunda, The Gambia October 12, 2008

Every cause needs a champion and our environment deserves the best. Especially in a society where over 65 % of the population have to live below the official minimum income subsistence threshold “ Environmental protection “ can be a very complex and abstract issue but as soon as we introduce a personal and human element we create a focal point for all to understand.

“ Greenie© “ is a staunch environmentalist, loves all things natural and especially trees. She lives in The Gambia and likes planting things, nursing them and watching them grow – her biggest horror are litter and waste in the environment and she is always happy and eager to explore new ways of re-using and re-cycling them and share her experience.

Our plan is to join her in her adventures of helping to make The Gambia an even more beautiful place to live in and to visit. Her stories will be told in little 24 page pamphlets, showing her in real-life situation photographs accompanied by fun and educational copy-writing. The booklets will be published by PRSP in collaboration with her Artist creator, Caroczel, produced to a professional standard and will be a fun way to create environmental awareness for all age groups within the community.

Fuel efficient wood-burning domestic stoves & Compressed bio-mass briquettes
Fuel efficient wood-burning domestic stoves & Compressed bio-mass briquettes

This type of stove has been developed and refined over the last 30 years. It is designed to use wood and other alternative bio-fuels in briquette format. This particular method of construction allows the harmful gases – which on a normal fire are seen as smoke – to be trapped and heated sufficiently to burn and create a secondary combustion. For the same amount of fuel we generate at least twice as much heat for cooking. Add to that other design features in the stove – better air control, a “ skirt “ around the pot base – and we increase its efficiency by as much as 3 times. In effect we only need one third of the fuel in comparison to an open fire to achieve the same result.

The stove will be custom designed for The Gambia’s conditions taking into account the maximum size of a standard domestic cooking pot and dietary requirements. It only comprises of 4 simple parts, its use is easy to learn and safe and it can be manufactured with tooling available on an industrial and local level from new or used steel and parts.
