“Briquette is a very new thing in my village and [I] am the only person who have tried using it and currently when it turned hard to use it, i got tired and now that’s why i need people to design a better and quick one. Removing the briquette from the pipe was very hard. As i said very few families have seen a briquette or use it. It will be a new thing to many.”

Biomass briquettes require no energy to be produced, other than physical input.

Briquettes
How? Most of the briquette press designs implemented in the developing world have been designed and developed on an open source platform directed by Cincinnati engineers Leland Hite & Dr. Zan Smith since 1994. Josphat uses a briquette press that was created in 1996 and has last been updated in february of 2011.

Secondary Prototypes
Existing Press We decided to build the same briquette press that Josphat has. To see how it worked and how it would compare to our earlier prototypes. The press is the most common, most developed and one of the oldest briquette press designs used in developing countries. Pressing the briquette took relatively no time, the most time was taken in pouring the slurry of organic matter and removing the briquette from the mold.

Multiplying Briquette Production Using multiple molds and mold plungers we could press more material simultaneously. X3 X6
X9
Due to the fact that the mold assembly (mold, mold plunger, drainage tube, and end cap) is one of the hardest things to make for the briquette machine we decided to look at how we could multiply the amounts of briquettes within one mold.

Briquette Disks By increasing the amount of slurry in the mold, the size of the mold and using disks that have a tight fit we have separated the slurry in three tiers, which produces three briquettes per mold per press. disks could be sliced from plunger for perfect fit.
Similar disks are already used as part of the mold plunger but have not yet been adapted to separate the slurry in tiers and create multiple briquettes.
