The realisation that deforestation and woodfuel shortages are likely to become pressing problems in many countries has turned attention to other types of biomass fuel. Agricultural residues are, in principle, one of the most important of these. They arise in large volumes and in the rural areas which are often subject to some of the worst pressures of wood shortage.
This document is about "Choices". Briquetting for any operation requires a biomass mold of one type or another, whether it’s a small village, single family, or classroom operation. You have “choices” and there are no wrong or right, best or worst, good or bad molds for making biomass briquettes. A variety of molds will work equally well and one type may be best suited for you depending on the availability of construction materials and tools, cost, skill level, and briquetting requirements."

For Use As Fuel Rice husk, which is a large portion of biomass produced in the rice growing regions has been lying waste at the rice mills in most part of this country. It was investigated as a source of solid fuel; two sets of solid fuel briquettes were produced from rice husk using starch and gum Arabic as binders.
A Boise State University study proves that low-energy feedstocks can be densified and when combusted produce heat output comparable to higher energy content fuels.
The Easy BioGrind© biomass grinder was designed to grind dry biomass and to accomplish a number of goals. The objectives were the flexibility to grind a wide variety of dry biomasses, low-cost, easy to build using mostly hand tools, easy to operate, easy to maintain and require no welding.

This small press is suggested for single-family use, classroom demonstrations, or a small village operation where a small footprint, low cost, and easy to build press using hand tools are required.
However, individual households can reduce their need for wood and charcoal by making their own fuel, called fuel briquettes, from waste plant materials in their own environment. Fuel briquettes can be made from plant materials that normally go to waste, including sawdust, paper, charcoal fines, leaves, husks and other agricultural wastes.
The sugarcane plant is an exemplar of how nature can provide us with renewable resources to sustain ourselves without dependency upon unsustainable and damaging fossil fuels. Across the world research is being done to see how this humble plant can be used to provide alternatives to anything from petrol to plastics.
The press is designed to accommodate a biomass mold height of 16” for either a 3” or 4” diameter.
The press is designed to accommodate a biomass mold height of 3 ½” with either a 3” or 4” diameter. It will produce a briquette 3” in diameter, 1 ¼” tall with at center hole.
If PVC is not available or expensive in your area then the 3 inch square wood mold could be an alternate.
Fibers from the banana plant could be a new binder for sawdust other than paper pulp. Biomass from banana plant waste is usable in a fuel briquette under limited conditions and this paper reviews those limitations.
The Easy BioChop© biomass chopper/cutter was designed to cut both wet and dry biomass and to accomplish a number of goals. The objectives were low-cost, easy to build using mostly hand tools, easy to operate, easy to maintain and requires no welding. Below are a few comments regarding use and construction.
