Senegal's manufacturing sector contributed 15.3% to GDP in 1998, registering annual growth increases consistently during the 1980s, 1990s, and into the 21st century. Industry accounted for 21% of GDP in 2000.
Agroindustry (oil mills, sugar refineries, fish canneries, flour mills, bakeries, beverage and dairy processing, and tobacco manufacturing) plays a key role and accounts for some 40% of value added. Especially important are groundnut-processing mills. The textile industry includes four cotton-ginning mills, factories for weaving, dyeing, and printing cloth, and plants that produce mattresses, thread, and hats. Cement, refined petroleum products, fertilizers, and phosphoric acid are produced. Other industrial products include plywood, boats, bicycles, soap, leather goods, paints, acetylene, sulfuric acid, and cigarettes.
Senegal's oil potential has yet to be completely ascertained. There is a refinery at Dakar, with production capacity of 27,000 barrels per day. Petrosen, the state-owned oil company, is encouraging exploration. One natural gas field has been discovered.
