Companies in Johannesburg

Sasol is South Africa's largest chemical and energy company and the world leader in coal-to-liquids (CTL) and gas-to-liquids (GTL) technology. Founded in 1950 to secure South Africa's fuel independence, the company is headquartered in Johannesburg, employs about 28,000 people, and operates the Secunda complex — the largest CTL facility on earth, converting coal into fuels and a wide range of chemical feedstocks. Sasol's chemical portfolio includes solvents, surfactants, waxes, polymers, and high-purity alcohols used in detergents, paints, pharmaceuticals, and personal care products, sold through a global sales network. The company also operates a major petrochemical complex at Lake Charles, Louisiana, and produces low-carbon fuels from gas at its GTL plant in Qatar. For buyers of specialty chemicals, Sasol is a benchmark supplier of synthetic waxes, alcohols, and solvents, with consistent quality and one of the industry's most unusual supply chains: chemicals derived from coal and gas rather than crude oil.

MTN Group traces its origins to 1994, when the newly democratic South Africa awarded its first mobile licences and a consortium led by a small team of entrepreneurs founded Mobile Telephone Networks. The company listed on the Johannesburg Stock Exchange in 1995 and grew rapidly through the 2000s by acquiring operators across Africa, including Nigeria's Econet Wireless in 2001, which became MTN Nigeria and today accounts for roughly a third of group revenue. Over three decades MTN has transformed from a single-country GSM operator into Africa's largest telecommunications group by subscribers, serving more than 290 million customers across 17 markets in Africa and the Middle East, with its headquarters in Johannesburg. MTN's core business spans mobile voice and data, fintech, enterprise solutions, and wholesale carrier services. Its fintech arm, MTN MoMo, has become one of Africa's most successful mobile money platforms, processing hundreds of millions of transactions monthly across markets where traditional banking infrastructure is thin, and the group has aggressively rolled out 4G and 5G networks through its Project Win and Ambition 2025 strategies. MTN is also a major technology buyer: it operates one of the continent's largest network infrastructure estates, procuring base stations, fibre, microwave equipment, data-centre hardware, and thousands of handsets and IoT devices annually from global vendors, making it a critical anchor customer for telecom equipment suppliers. For B2B suppliers, MTN represents a high-volume, creditworthy procurement channel into African telecommunications. The group runs centralized procurement through MTN Group Procurement in Johannesburg, with regional hubs in Lagos, Accra, and Kampala, and maintains a formal vendor registration and tender process for network equipment, energy systems, and IT infrastructure. Its continued capital expenditure of over 40 billion rand per year on network rollout and its drive to expand rural coverage mean steady demand for solar-powered cell sites, battery storage, and cost-optimized network components, particularly from suppliers who can offer local support and financing flexibility across multiple African markets.

Sappi's roots reach back to 1936, when the South African Pulp and Paper Industries was founded near Durban to produce paper from locally grown timber. The company changed its name to Sappi in 1968, expanded into packaging and fine paper in the 1970s, and made its defining international move in the 1990s by acquiring European and North American operations, including the purchase of S.D. Warren in the United States and several European coated-paper mills, which made Sappi one of the world's largest producers of coated fine paper. Since 2015 the group has deliberately pivoted from graphic paper toward higher-growth segments, building a leading global position in dissolving wood pulp, packaging and speciality papers, and biomaterials. Sappi today operates 10 mills across South Africa, Europe and North America, employing around 11,000 people, and is the world's largest producer of dissolving wood pulp, a key raw material for viscose textiles, cellulose-based pharmaceuticals and personal-care products. Its portfolio spans dissolving pulp, packaging papers, specialty papers such as release liners and labels, and graphic paper, with a fast-growing biomaterials division developing lignin-based products and nanocellulose. The company is vertically integrated from its own forestry operations in South Africa through to finished specialty grades, and its Southern African operations generate electricity from biomass and are working toward carbon-neutral production. For B2B buyers, Sappi is a strategic source for high-purity dissolving pulp and specialty papers, particularly for textile manufacturers, pharmaceutical excipient producers, and label and packaging converters. The group's Southern African operations export the majority of their output to Asia, with China and India among the largest destinations, and it runs a global commercial network spanning 50 countries. Sappi maintains long-term supply contracts with major viscose producers and offers technical-grade consistency, FSC certification, and a documented sustainability chain of custody, making it a dependable partner for manufacturers seeking stable, certified wood-based raw materials.

Its operations include the Obuasi mine in Ghana, one of Africa's richest gold deposits, mines in the Democratic Republic of Congo and Tanzania, and operations in Brazil, Argentina, Colombia, Australia and the United States. AngloGold has shifted its portfolio toward higher-grade, lower-cost assets and is investing in renewable energy and autonomous mining technologies to reduce costs and carbon emissions. For B2B buyers, AngloGold supplies gold doré and bullion to refiners, central banks and jewellery manufacturers, with long-term offtake agreements and industry-leading safety standards. Its global diversification, reserve base and improving cost profile make it a significant player in the international gold supply chain.
