How to make fuel briquettes without a press

  1. 1. HOW TO MAKE FUELBRIQUETTES WITHOUT A PRESS Joyce Lockard Fuel Briquette Team Beaverton Rotary Club in OR, USA rj.lockard@frontier.com
  2. 2. About half of the world’s people use wood or charcoal for cookingand heating. Cutting of trees for fuel and for subsistence farmingis resulting in loss of 2-3% of the world’s forests each year.
  3. 3. In some countries, buying fuel for cooking maytake as much as half of a family’s income, andmany families can afford to cook only once ortwice a day.However, individual households can reduce theirneed for wood and charcoal by making their ownfuel, called fuel briquettes, from waste plantmaterials in their own environment.
  4. 4. Fuel briquettes can be made from plant materials thatnormally go to waste, including sawdust, paper, charcoalfines, leaves, husks and other agricultural wastes.
  5. 5. These are fuel briquettes made with (L-R) mini-Bryant, Petersonand Lee Hite presses, a briquette made with a bottle mold, and afuel ball made by hand.
  6. 6. In villages around the world, fuel briquettes are being madewith a wood or metal press such as the large mini-Bryant or smaller Peterson presses shown here. BUT WHAT IF YOU DON’T HAVE A PRESS???
  7. 7. YOU CAN MAKE BRIQUETTES BY HAND WITH A PLASTIC MOLD!You can use a plastic bottle or other straight-sided plastic containerabout 4”-8” in diameter to shape the briquette. You will need apiece of wood or banana plant stem or a tin can that will fit into thecontainer as a piston to press water out of the briquette mix, aknife, a plastic bag and some wire.
  8. 8. First, prepare the briquette mix. Soak torn-up waste paper inwater for one or two days to soften the paper and release thefibers, which will bind the briquette materials together.
  9. 9. Rub the soaked paper between your hands until it lookslike soft porridge and no pieces can be seen. This takestime! Do it well!
  10. 10. You can use a mortar and pestle or a tool forpounding to speed up processing of the paper.
  11. 11. Measure out 1 part of soaked paper to 3 or 4 parts of sawdust.Paper plus sawdust are the simplest mix, but you can add ricehusks, charcoal fines, chopped grass and leaves, pine needlesand other materials. Use roughly 20% paper.
  12. 12. Or, instead of using paper, you can boil cassava flour orcassava peels until they are very soft and add enoughof the paste to bind the sawdust together.
  13. 13. Mix the paper with the sawdust and enough water sothat the mix will hold together when it is squeezed.
  14. 14. Make a bottle mold. Cut off the upper quarter of a 2L sodabottle or other straight-sided plastic bottle.
  15. 15. Make about a dozen drainage holes in the bottom andlower sides by burning holes with a hot wire.
  16. 16. Prepare a thin plastic bag to use as a liner to get the finishedbriquette out of the bottle. Punch about a dozen drainage holesin the bottom and lower sides of the bag so water can drain out.
  17. 17. Instead of a bottle, you can use a container with tapering sides suchas a bucket or a plastic flower pot for the mold and a second one asthe piston. The flower pot already has drainage slits around thebottom, and slits have been cut in the bottom edge of the bucket inthe photo. Be sure to use a plastic liner with drainage holes.
  18. 18. Put a big handful of briquette mix into the plasticbag and insert the bag into the bottle mold.
  19. 19. Add more mix to the bag and press out water with a can orwith a piece of wood or banana stem that fits into the mold.
  20. 20. Put the mold on the ground or floor and standon it to press out as much water as possible.
  21. 21. Pull the bag out of the mold and remove the briquette.
  22. 22. Dry the briquettes in the sun for 3-7 days. Briquettes that arenot dry will smoke when they are burned, so dry them well!
  23. 23. If you don’t have a mold, you can make fuel balls bysqueezing the briquette mix into balls with your hands.Dry them in the sun.
  24. 24. We have shown how an alternative fuel for cooking can bemade by hand from waste paper and sawdust using a simpleplastic mold for shaping the briquettes or by making fuelballs by hand.Please help spread this basic fuel briquette technologywherever finding wood for cooking is a problem. Helppeople cook, and reduce the cutting of trees for fuel!For more information, contact rj.lockard@frontier.com
