This product range was further extended in the 1980s to include both phosphate- and potassium-based fertilizers. Sasol now sells an extensive range of fertilizers and explosives to local and international markets, and is a world leader in its low-density ammonium nitrate technology. With the extraction of chemicals from its Fischer–Tropsch product slate coupled with downstream functionalization and on-purpose chemical production facilities, Sasol moved from being just a South African fuels company to become an international integrated energy and chemicals company with over 200 chemical products being sold worldwide. Some of the main products produced are diesel, petrol (gasoline), naphtha, kerosene (jet fuel), liquid petroleum gas (LPG), olefins, alcohols, polymers, solvents, surfactants (detergent alcohols and oil-field chemicals), co-monomers, ammonia, methanol, various phenolics, sulphur, illuminating paraffin, bitumen, acrylates, and fuel oil. These products are used in the production process of numerous everyday products made worldwide and benefit the lives of millions of people around the world. They include hot-melt adhesives, car products, microchip coatings, printing ink, household and industrial paints, mobile phones, circuit boards, transport fuels, compact discs, medical lasers, sun creams, perfumes and plastic bottles. In South Africa, the chemical businesses are integrated in the Fischer–Tropsch value chain. Outside South Africa, the company operates chemical businesses based on backward integration into feedstock and/or competitive market positions for example in Europe, Asia, and the United States. Greenhouse gas emissions Sasol's Secunda CTL plant is as of 2020 the world's largest single emitter of greenhouse gas, at 56.5 million tonnes CO2 a year. However, if Afşin-Elbistan C power station in Turkey is built and operated at planned capacity it would emit over 60 million tonnes a year. Air Liquide acquired the 42,000 tons/day oxygen production in 2020, with plans for 900 MW power plants to reduce CO2 emissions. According to independent researchers, Secunda “produces without doubt the most polluting liquid fuels in the world,” said Lauri Myllyvirta, lead analyst for the Centre for Energy Research and Clean Air, an independent research body. “The most alarming part is that Sasol is delaying and opposing South Africa’s new air pollutant emissions standards that would more than halve the health impacts of industrial emissions.” Operations Sasol has exploration, development, production, marketing and sales operations in 31 countries across the world, including Southern Africa, the rest of Africa, the Americas, Europe, the Middle East (West Asia), Russia, Southeast Asia, East Asia, and Oceania.
