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!

For those of you interested in the ARTI biogas system, please have a look at our new report on "Anaerobic Digestion of Canteen Waste at a Secondary School in Dar es Salaam, Tanzania".

After the evaluation of the ARTI system on household level, this follow-up study evaluates the suitability of the same technology applied on a bigger scale. You will find the detailed results on our website in the

Two Days at the Appropriate Rural Technology Institute Field Research Station in Phaltan, India
Working with Hemant Mahajan (ARTI Engineer, with the white cap) to demonstrate charcoal production using Top-Down pyrolysis and off-gas combustion. ( Nov 28-29, 2000)

Having come all the way to India to present a paper on this topic (Preliminary Tests on Charcoal Making-
Pyrolysis Gas Burners) it seemed appropriate to at least try and demonstrate the concept. So after the conference I spent two quick days in Phaltan, building, modifying and trying out a oil drum charcoal maker modeled after one I built back in Canada three years ago.

This shows the mostly full drum of cotton stalks. This trial did not work so we moved on to a denser fuel, bamboo.

Here the drum full of vertically packed bamboo is ignited on top. The drum has a few dozen small holes in the bottom for
primary air to promote the partial combustion, or pyrolysis of the bamboo. During startup no air is allowed into the drum from
below. The fire on top needs to be burning over the whole surface. Then a small hole is dug in the dirt at the bottom of the drum to allow some air up through the bamboo to the fire on top. This increases the fire intensity and causes the fire to move down into the bamboo below the top. After five or ten minutes the burner can be placed on top.

With the burner placed on top the flames are extinguished and the bamboo smoulders or pyrolyses. Notice the small opening in the dirt at the bottom of the drum.

Commercialisation of Improved Biomass Fuels and Cooking Devices in India: Scale Up Project

Indoor Air Pollution (IAP) is a major health threat for women and children under 5 in the developing world. According to World Health Organisation, annually, 500,000 women and children in rural India die prematurely due to diseases linked to long term exposure to IAP. A major cause of IAP is smoke in the rural kitchens, due to use of traditional biofuels (firewood, agrowaste, dungcakes, etc.) in traditional cookstoves. Economic constraints of rural households and poor distribution network of modern fossil fuels such as kerosene and LPG, result into the rural households continuing to depend on locally available and free-of-cost or cheap biofuels. Therefore, a more practical solution is to develop and disseminate biofueled clean cooking devices.

Plan of Action

Based on the lessons learnt from the pilot project, the scale up project aims to reach out to about 15,00,000 rural households in Maharashtra and around 50,000 rural households in Gujarat. It is envisaged that this project will successfully establish sustainable business chains for supplying the clean biomass energy cooking products the rural population in Maharashtra and Gujarat states. This will be achieved through active participation of rural entrepreneurs, Self Help Groups (SHGs) and Non-Government Organisations (NGOs). ARTI, with its long standing experience in development and dissemination of rural technologies, will drive the synergetic working between the various NGOs and entrepreneurs.
