Fruits and Vegetables industry produces large volumes of wastes, both solids and liquid, resulting f rom the production, preparation and consumption of its products. Processing of fruits and vegetables produces two types of waste - a solid waste of peel/skin, seeds, stones etc., a liquid waste of juice and wash-waters. In some fruits the discarded portion can be very high (e.g. mango 30-50%, banana 20%, orange 30-50%). These wastes pose increasing disposal and potential severe pollution problems and represent a loss of valuable biomass and nutrients. Beside their pollution and hazard aspects, in many cases, fruits and vegetables processing wastes might have a potential for conversion into useful products of higher value as by-product, or even as raw material for other industries, or for use as food or feed after biological treatment. The composition of wastes emerging from fruits and vegetables processing industry is extremely varied and depends on both the nature of the product and the production technique employed. Furthermore, the volume and concentration of the waste material will not be constant. This may cause some problems in managing a consistent working process due to fluctuations in the nature, composition and quantity of raw materials. Quantity and quality of wastes is important on the decision of evaluation of wastes.
