Manufacturing is helping improve the lives of women and girls in East Africa with its efficient charcoal-burning Jikokoa™ stove and opportunities for women to participate in its workforce. The stove itself represents a step-change in the design and efficiency of charcoal-burning cookstoves. As well as being an aspirational household product, it cuts down on smoke and soot by more than 60% compared to the widely used Kenya ceramic jiko. But it’s not just women using the stoves who benefit. With all manufacture now done in a new state-of-the-art factory in Kenya, BURN emphasises that all jobs are open to both men and women at all levels – just over half of its workforce are women.

A loaded kinyanjui type barrel kiln carbonizing maize cobs
free fuel!
a full kin of maize cob and branch charcoal made in less the a day
the maize cob charcoal cooks with high heat and little smoke.

Four very good reasons why to make your own charcoal from dry maize cobs.

  1. They are FREE!! (minimal processing required and are widely available as a farm waste product)
  2. Maize cob charcoal is very easy to make and leaves few charcoal fines. (no need for expensive briquetting)
  3. They are easy to light and burn very hot with little ash and are perfect for cooking a quick meal.
  4. Using maize cob charcoal means ZERO reliance on tree's and forests, LPG gas or unreliable and expensive electricity supplies for your cooking fuel needs. And with a Cookswell Jiko you can bake, boil, roast and toast all of your favorite foods

The Low Smoke Chulha has been enabled by Philips Design in close co-operation with NGOs, self-help groups, local entrepreneurs and potential users. Low Smoke Chulha provides a safer home environment for families, reduces the risk of respiratory illness, and supports indigenous ways of cooking. The Low Smoke Chulha is not only smokeless but also helps every household save 10 kilos of firewood each house each day which is 4 tones of firewood a year!

The Kitengela Arboretum Promoting sustainable agro-energy technologies and conservation education. Kenya Seeds of Change An initiative contributing towards national afforestation through direct seeding of woodlots. Concept Compiled by: Teddy M. Kinyanjui Sustainability Consultant Kitengela Arboretum Po. Box 23058 Lower Kabete Nairobi, Kenya. April 2009

**Kenya Seeds of Change**
*Overview*
The degraded state of Kenya’s national and private forests (and therefore, the overall environmental health of the country) borders on the point of no return. Unless large scale forestry efforts are undertaken by both the public and private sector in the next few years, the damage that has been done to the countries forests will become irreversible. Due to the slow pace of natural regeneration of forests (as compared to their exploitation), a boost is sorely needed to meet current and future demands by Kenya’s ever growing population for sustainably grown wood by-products, especially the charcoal and firewood that is used daily by 80% of the country’s population.
The Kenya Seeds Of Change initiative aims to contribute towards national afforestaion by land owners through the countrywide sales of inexpensive tree seeds and the promotion of direct seeding woodlot establishment. Seeds are by far the best method of promoting wide scale tree planting in Kenya. These are some of the benefits from the direct planting of tree seeds compared to planting seedlings:

  • Seeds are Cheaper! (At roughly 0.25cents per tree compared to 20+ shillings per seedling)
  • The tree’s hardiness and survivability increases.
  • Thousands of seeds can be transported and stored much more easily then thousands of seedlings can until the planting time comes.
  • Seeds can be massively disseminated through existing retail outlets with minimal price increments from producer to consumer. Tree seedlings face problems of availability at the right time, dissemination logistics etc.
  • Partially domesticated indigenous tree species are best grown from seed. They are already adapted to Kenya’s climate, soils and pests and the trees are currently widely used and understood by the population.
  • Seeds simplify the enhancement of the genetic diversity of planted woodlots.
  • The above/below ground biomass ratio is more conducive to healthy growth when a tree is planted from seed.
  • Overall financial losses and risks from drought, animals etc. are significantly less under direct seeding.

Limited Access to Good Seed

  • From large commercial plantations to small scale rural and urban farmers, the access to purchase certified tree seeds according to their growing zones and uses is extremely limited to anyone who would like to plant trees.
  • Currently the only place to buy graded, certified tree seeds is at KEFRI (The Kenya Forestry Research Institute), located in Muguga, on the outskirts of Nairobi.
  • In contrast all the Nakumatt and Uchumi supermarket chains and all of the Agro-Vets in small or large towns and cities stock a variety of seeds ie. sukuma wiki (Kale) and maize etc.
  • Which of course raises the question; why don’t they all stock small packages of tree seeds that are suited to their market base?

This is what the Kenya Seeds of Change initiative has been started to get done.

Magh CM Woodgas Good Stove http://e-maghcm.blogspot.com/ designed recently is a very low cost TLUD stove meant for Common Man (CM). This can be produced by the local communities with less than 8 dollars (USD). Under Magh CM series I have designed many stoves / burners in the past. This stove design is one of the most acceptable stoves, as it has the options to run on forced air / natural draft. Most importantly the convenient charcoal / ash removal facility is created at the bottom, the grate can be simply lifted using a wire and immediately refilled for reuse. The additional window for secondary air in case of no power, the primary air control and the 12 V DC powered fan makes it like a geared vehicle for multiple options to control the heat / flame / updraft. Used the most commonly available oil tin can of 12 inches x 9 inches x 9 inches with a combustion chamber of 6 inches diameter and 9 inches height for the convenience of adoption for a family of 5 members cooking needs. The tin cans are easily available all over India. Posting here the pictures and the design for your valuable comments for improvement. I am thankful to all for your valuable suggestions in the past. This is the 30th Good Stove design of Avan and Magh series since last 4 years of my research and design. Happy to share that the people who have seen this stove have paid money in advance for having these Stoves. For more pictures and info see http://e-maghcm.blogspot.com/ and http://picasaweb.google.com/saibhaskar.gsbc

As the United States biomass thermal and power industry continues to expand, new reliable technologies offering higher efficiency solutions must be introduced. The newly introduced EOS series biomass gasification boiler is among the most energy efficient of AESI’s high-performance, low-maintenance biomass energy plants. The EOS series provides thermal outputs ranging from 600,000 BTU/hr to 20 million BTU/hr, and can be staged to provide increased capacity.

Designed and built by the leaders in the biomass waste to energy market in Europe, Uniconfort, the EOS series builds upon over 50 years of experience and over 4000 successful installations throughout the world. When asked about the highly efficient EOS series, CEO of Uniconfort Davis Zinetti notes, “we must not forget that greater efficiency is associated with less CO2 production. Choosing EOS, therefore, means making a choice in favor of the environment.”

Dear Friends

I fired two of the rings today for a brief time, perhaps 3 hours at temperature. No particular care was taken regarding the slow initial temperature rise.
