Description: Charcoal is the blackish residue consisting of impure carbon obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, i.e. the heating of wood, sugar, bone char, or other substances in the absence of oxygen. The resulting soft, brittle, lightweight, black, porous material resembles coal and is 85% to 98% carbon with the remainder consisting of volatile chemicals and ash.

Description: Ginger (Zingiber Officinale) is a commodity that is highly valued in international markets for its aroma, pungency and high oil and Aleo resin content. Nigeria is the third largest exporter of ginger in the world after China and India. Most of the dried ginger that are available for international trade are simply sun dried over a few days, but artificial drying is also used in areas lacking a defined dry season to coincide with the harvest. The rhizome is dried to between 10 and 12 per cent moisture content. Dried ginger is usually presented in a split or sliced form. Splitting is said to be preferred to slicing, as slicing loses more flavour, but the sliced are easier to grind and this is the predominant form of dried ginger currently in the market.
