** PROBLEM STATEMENT: **
Traditional cooking fuels pose several issues, including cost (for LPG, propane, or similar fuels) and scarcity due to deforestation or large amounts of time spent gathering it (for wood). A method to produce alternative fuels from readily available waste materials could be developed to reduce this dependence, while providing a wide array of other benefits with few downsides.

** PROJECT GOALS: **
The Briquette Brigade has two goals that will be approached during this project. The first is to develop and test several combinations of waste materials to determine ideal materials and combinations that can be used for briquettes. Possible materials will include newspaper, sawdust, corn and rice husks, coffee and tea waste, and leaves, among others.

The second goal will be to construct a manually operated press that can be assembled without the use of a welder. This is to make it more accessible to areas where machining may not be available locally. It also adds the attraction of a DIY kit for people to construct at home when marketing it to developed communities like the US. This product will be an attractive addition to the already popular green revolution in many first world countries.

If our team is successful in completing both of our goals, we will have designed an alternative fuel that will repurpose waste, reduce indoor air pollution, provide a new income niche, and slow down deforestation. We will be focusing on Nepal as our target location for these briquettes, since Will has had experience with their culture and processes.
 * POSITIVE IMPACTS: **

Some potential issues with the project are that the briquettes may not burn as efficiently or as hot when compared to wood or gas. The other issue is that we are not yet sure how long each briquette will take to make. Since this a only a quarter-long project, time will be an issue.

=Background Information=

Nepal & Sustainable Technologies
The foundation of this project idea came from Will's work in Nepal making briquettes from locally sourced waste. These briquettes could be tailored to the specific resources of different areas as a way to address the severe deforestation caused by the use of wood fuels. Ultimately, we want to continue this type of production, looking into different material combinations and how well they burn. FoST-Nepal

Aprovecho Briquette Information
We got in contact with Don Nason, who directed us to the Engineers Without Borders' open source on DIY Biomass Briquettes and presses, which serves as a very insightful compendium on different simple press designs, expectations when using certain materials, and specific caloric values for heat produced by each material.

Briquettes Around the World
__Uganda Study and What We Learned From It__ Urban Uganda Briquettes

Briquettes are an alternative fuel source that is currently gaining popularity in Uganda. They have been successfully integrated into the economy in other developing nations such as China and Thailand. Briquettes use composed of commonly found organic household waste, such as peanut shells, banana peels, corn husks, sawdust etc. and are compressed either by hand, or by machine into small dense products that be used in replacement of charcoal and/or excess amounts of wood harvested from nearby forests.

-Use materials with a high Nitrogen content -Make the briquettes as dense as possible -Try to make briquettes that will burn for more than 30 minutes
