“Banana Peelings as Charcoal Briquette”
Charcoal (Cooking fuel)
Prior to the industrial revolution charcoal was occasionally used as a cooking fuel. Modern "charcoal briquettes", widely used for outdoor grilling and barbecues in backyards and on camping trips, imitate this use, but are not pure charcoal. They are usually compacted mixtures of sawdust with additives like coal or coke and various binders. Charcoal is the dark grey residue consisting of carbon, and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen (see pyrolysis, char and biochar). It is usually an impure form of carbon as it contains ash; however, sugar charcoal is among the purest forms of carbon readily available, particularly if it is not made by heating but by a dehydration with sulfuric acid to minimise introducing new impurities, as impurities can be removed from the sugar in advance. The resulting soft, brittle, lightweight, black, porous material resembles coal. Charcoal is a carbon-containing substance made from wood, naturally black and powdery. Charcoal is made from wood by heating it in airless space in high temperature. The wood will not burn, but instead turn into charcoal. The by-product of making charcoal is tar and turpentine. People use it for different things such as cooking on a barbecue grill, and in painting. http://en.wikipedia.org/wiki/Charcoal
Charcoal is a desirable fuel because it produces a hot, long-lasting, virtually smokeless fire. Combined with other materials and formed into uniform chunks called briquettes, it is popularly used for outdoor cooking in the United States. According to the barbecue Industry Association, Americans bought 883,748 tons of charcoal briquettes in 1997. Basic charcoal is produced by burning a carbon-rich material such as wood in a low-oxygen atmosphere....
