Recycling paper as alternative to charcoal
Paper comes from wood and charcoal is derived from wood. My idea is to recycle used papers, such as newspapers and old documents, to become an alternative for charcoal. The procedure would be to soak several used papers in water for some time. Then compact them using hands or other means to reasonable sizes. Then let them dry. You can now use them as an alternative for charcoal. It may function differently than charcoal but it will work.
