Industry accounted for 27% of GDP in 2000, and is oriented toward the processing of raw materials and of light manufactured goods for domestic consumption. The sector has suffered from a lack of foreign exchange, high import costs, unreliable local services, and political instability. The Wellington Industrial Estate, covering 46 hectares just east of Freetown, was developed in the 1960s by the government to encourage investments. Its factories produce a variety of products, including cement, nails, shoes, oxygen, cigarettes, beer and soft drinks, paint, and knitted goods. Timber for prefabricated buildings is milled, and another factory produces modern furniture. Small factories in the Freetown area process tuna and palm oil. Oyster farming and shrimp production dominate the fishing industry. There are no proven oil reserves in the country, but there is one oil refinery. In 1992, the oil refinery in Freetown closed due to lack of capital for crude oil imports; in 1994 the facility was sold to Unipetrol of Nigeria. Its production capacity in 2002 was 10,000 barrels per day. Village craft products include a popular cloth, rope, sail canvas, boats, wood carvings, baskets, and leather goods.
