Cementless Blocks
Due to the increasing cost of cement, the Forest Products and Industries Development Commission (FORPRIDECOM) conducted a research that will produce blocks from soil and water, or a combination of one or two different wastes or wood waste like rice hull, coconut coirdust or sawdust. The binder used is lime.
Lime can be found almost anywhere in the Philippines.
Charcoal from Old Newspaper
Do not waste old newspaper! During “brown-out” or when you run out of cooking gas, you can
make use of charcoal from old newspapers.
Procedure:
1. Soak old newspapers and magazines for about two hours in water.
2. When the water is thoroughly soaked and soft, tear chunks of paper enough to be pressed into two inches balls.
3. Press out the water.
4. Dry the wet briquettes on the concrete floor during hot and sunny days.
5. When thoroughly dried store in plastic bags so that the briquettes will not absorb moisture.
6. Use paper briquettes as substitute for wood charcoal.

Charcoal Briquettes from Agricultural Waste
Charcoal briquettes is powdered or crushed charcoal mashed and molded using binder which
can either be cassava, corn or camote powder. As fuel, charcoal briquettes gives more heat
than ordinary charcoal or wood. It is almost smoked-free and heat is consistent. The fire lasts
longer than ordinary charcoal and can be easily stored or transported because it is lighter in
weight.
The briquettes which are hard can be used in industrial ovens instead of using carbon in
melting the metal from iron ore or stone.
Charcoal briquettes can be made from rice hull, coconut barks, twigs or shells or husk and
powder from husk and wooden saw dust, wood trimmings, twigs, branches and the like.
Aside from fuel, the briquettes can be used in different industries such as in making carbon
disulfide, carbon electrodes, carbon tetrachloride, carbon carbide, sodium cyanide and
activated charcoal. Activated carbon is used in filtering air or water.
