How to Make Fuel using carabao dung and rice hulls
Cattle dung and rice hulls can be used as fuel for cooking purposes, especially in rural areas where firewood is getting scarce.
Procedure:
1. Mix in a pail or in any available basin or kerosene can one part rice hull to six parts fresh manure. Animal manure should be fresh and moist so it can bind the mixture when dry.
2. Mix the mixture thoroughly with the use of shovels.
3. Press the mixture to remove the excess moisture.
4. Pour the mixture into tall milk cans which serve as mold. Both ends of the can should be opened to facilitate removal of the briquets.
5. Remove the molds and dry the briquets to the sun for three to four days. At this stage, the briquets have a moisture content of around eight to 12 percent.

Fuel using old newspaper
Don’t throw away old newspapers. During brownouts or when you run out of gas for cooking, fuel from old newspapers can be used.
Procedure:
1. Soak old newspapers in water (or inside pages of magazines) for about 2 hours.
2. After soaking, tear into pieces, mash into balls about 2 inches in diameter.
3. Squeeze out the water.
4. Spread over a cement surface under the sun for drying.
5. After drying is complete, pack in plastic bags so that moisture will not be absorbed.
6. Use as fuel as substitute for wood or charcoal.
