Industry is concentrated in the southern part of the country around Brazzaville and Pointe-Noire. Many industries, until recently, were partially or completely nationalized. Industry accounted for about 50% of GDP in 2001.
The largest industries are petroleum production, followed by food processing, including beverages and tobacco, chemicals, woodworking, metalworking and electrical industries, nonmetallic mineral products, paper and cardboard, and textiles. The ROC is the fourth-largest oil producer in sub-Saharan Africa, and the oil industry accounts for two-thirds of government revenue, 90% of export earnings, and close to 50% of GDP. There are an estimated 1.3 million tons of crude oil reserves in the country. An oil refinery at Pointe-Noire has a capacity of 21,000 barrels per day, but only 50% of the capacity is utilized. In 1996, the government privatized the refinery. Other industries include sawmills, sugar refineries, and cement factories. Artisans create distinctive jewelry, ceramics, and ebony and ivory sculptures. The timber industry was reviving in 2003.
