Introduction

• Madagascar is the 4th largest island and with rich vegetation, it is a biodiversity hotspot

• Uncontrolled logging, forest fire, traditional practices have depleted the forest cover threatening biodiversity, water resources and soil stability

• Additionally, it is one of the ten countries expected to be the most affected by climate change in the world

Energy Production Calculation

345 g of bio-briquettes was around 6 to 8 briquettes of different weights whichwere used to boil 5L of water. So total energy potential of this combination ofbriquette when added together ranges around 4000 to 8000 KJ approximately.

Conclusions and Future Scope

With the application of bio-briquettes and efficiency stoves, the wood will be saved, as well as the health of the kitchen workers

01Further R&D in Stoves, Press, modeling and experiments with bio-briquettes

02Dealing with social problems like ‘resistant to change’ mindset

03Establishment of a customer-friendly business plan
