Coffee wastewater, also known as coffee effluent, is a byproduct of coffee processing. Its treatment and disposal is an important environmental consideration for coffee processing as wastewater is a form of industrial water pollution.[1]
The unpicked fruit of the coffee tree, known as the coffee cherry, undergoes a long process to make it ready for consumption. This process often entails use of large quantities of water and the production of considerable amounts of solid and liquid waste. The type of waste is a result of the type of process that the coffee cherries go through. The conversion of the cherry to oro[note 1] or green bean (the dried coffee bean which is ready to be exported) is achieved through either a dry, semi-washed or fully washed process.
