Agro-industry comprises two sub-sectors: agro-food industry and export agro-industry. The brewing industry plays a leading role in the agro-food industry sub-sector. Cameroon is among the biggest brewers in Africa with an average production of four million hectolitres. Four breweries are active in the sector. Meanwhile, export agroindustry is led by large corporations such as CDC which is specialized in the production of banana, palm oil and rubber; SOSUCAM (sugar); SODECOTON (cotton); SOCAPALM (palm oil); HEVECAM (rubber); PHP and SPM (banana); SAFACAM (crude and refined palm oil)
ALUCAM is the leading company in the metallurgical sector. The company is specialized in the transformation of alumina into aluminium. ALUCAM produces 90,000 tons of aluminium ingots on average. The government, in partnership with Rio Tinto Alcan, has implemented a vast project on the extension of ALUCAM in order to increase the production capacity of the company to 300,000 tons per year
To date, the cement sub-sector is led by CIMENCAM, a Cameroon-based cement plant which has the monopoly of manufacturing this product in Cameroon. CIMENCAM has two clinker grinding plants; one in Douala which produces1,600,000
tons per year and the other in Figuil in the North region with an annual production of 100,000 tons. The overall production is
largely below the local demand estimated at 3 million tons. A project on the construction of a cement factory in Limbé to produce one million tons per year has been completed by the government and South Korean investors.
The sector is led by Cameroon Cotton Industry Corporation (CICAM) which produces 7,500 tons of cotton yarn and 32 million metres of printed fabric. Its branch, SOLICAM, manufactures terry cloth earmarked for exportation.
There are a few companies in this sector which manufacture detergents, perfumes, soaps, painting, pharmaceutical products, etc. The soap industry is highly developed; it is led by the Complexe Chimique Camerounais (CCC)
A good example of engineering industries is shipbuilding. The leading company is the Cameroon Shipyard and Industrial Engineering Ltd (CNIC). Initially the CNIC focused on ship repairs but is now involved in shipbuilding. In 2008, CNIC built the first drill barge in Africa. Other companies specialized in hardware and boiler engineering operate alongside CNIC.
