Industrial activities are almost exclusively concentrated in Bujumbura and accounted for an estimated 18% of the GDP in 2001. The industrial sector transforms to varying degrees agricultural and forestry products: cotton, coffee, tea, vegetable oil, and woods. There are also several small plants for soft drinks, blankets, footwear, soap, insecticides, building materials, furniture, and metal goods. The future of industrial development is largely linked to the development of political stability and the growth of electric power and transportation, as well as improved commercial relations with neighboring countries.
Industrial production rose almost 2% in 1998, the first time since ethnic warfare began in 1993. Production of sugar, milk, paints, soap, bottles, pharmaceutical products, and textiles increased between 10% and 40% in 1998. The Teza tea plant was reconstructed (after being destroyed by rebels in 1996), increasing production from 1997 by 59% in 1998. Mining projects were also resumed, including nickel and gold operations. The country has no known oil, natural gas, or coal resources. Since 2001, the construction industry recovered somewhat, as new building projects were started in Bujumbura. Brarudi, a brewery, is the country's largest and most reliable source of tax revenue. Brarudi beer has a good reputation in the region.
