In 2016, industry represented 22,2% of the total GDP of Ethiopia. While Ethiopia's industrial sector engages primarily in food processing, it also produces sugar, alcohol and soft drinks, cigarettes, cotton and textiles, footwear, soap, ethyl alcohol, and quicklime. Cement production is also significant. Industrial facilities are concentrated around Addis Ababa, depend heavily on agricultural inputs, and primarily serve the domestic market. Ethiopia has few proven oil and natural gas reserves, although the potential of these industries is seen as promising.
