Sustainable Fuel Consulting


Fiji & Timor-Lesté



The rocket stove aims to address multiple issues across health, quality of life and environmental sustainability.

Environmental Sustainability – Deforestation is an issue across the globe and residential use of wood for cooking is a large contributor to the cutting down of trees in developing countries. Removal of trees reduces the Earth’s capacity to process the carbon dioxide released from human activity. Additionally, this “stored” carbon is then released when combusted. Carbon dioxide, methane and carbon monoxide is released in the burning of wood – when inefficient combustion occurs, black carbon is emitted. Black carbon is one of the top contributors to global warming.

Health – Respiratory issues associated with cooking are estimated to result in over 4.3 million deaths per year. Current methods of burning fuels for cooking are inefficient, cause a lot of smoke and production of harmful gases.

Quality of life – The smoke from inefficient combustion also results in significant discomfort during cooking, causing itchy eyes, coughing and carbon (soot) on the walls and roof.


Project Everest has gained an organisational understanding of the state of residential and commercial fuel consumption in Fiji. The Fiji team has clearly identified their target customer and achieved validation of their first product, the Rocket Stove, through achieving a number of sales over the Dec 17- Jul 18 period.

Due to the success of Rocket Stoves in Fiji Project Everest sought to build an organisational understanding of fuel use in Timor-Leste and Cambodia. Within these countries teams have gained an understanding of the customer segment and their identified problems through an empathy approach. 


The proposed rocket stove aims to reduce the required fuel required and smoke emitted (especially harmful gases such as carbon monoxide as a result from incomplete combustion). It works with all solid fuels such as wood, biomass briquettes and other combustible waste such as animal dung.

Through increasing airflow it ensures that more complete combustion can occur, increasing heat output, reducing production of harmful carbon monoxide and reducing the amount of fuel required.
