  • Waste paper can also be used as binder. It is torn into strips, soaked and macerated by hand to release the fibers, then added at about 20-25% by volume to seived charcoal dust. Paper may be available in towns, but cassava flour or the dirt from dead termite nests will likely be the best in rural areas. There are now six groups of women/AIDS patients and others making charcoal pellets in Uganda.
