The oil extraction industry generate two by-products, an aqueous effluent,
olive mill wastewater (OMWW) and a solid residue, olive mill solid waste
(OMSW).
In olive-oil-producing countries, large amounts of waste material are generated as by-product for which there is no ready use and in some cases may have a negative value because of the cost of disposal. Most of these countries depend on fossil fuels for their energy uses, and olive mill wastes can be used to supplement such energy sources using the...
