Sasol(SSL)
HQ ZA
South African integrated energy and chemicals company (JSE/NYSE-listed); unique in the LAB market for using Fischer-Tropsch (FT) wax cracking to produce its own normal paraffins (NP) — the LAB feedstock — rather than sourcing from oil refineries. Sasol operated LAB plants in Lake Charles, Louisiana (USA) and Augusta, Sicily (Italy); both were mothballed in Q2-Q3 2025 due to 'decline in competitiveness due to energy costs in Europe and market oversupply.' Also produces synthetic fuels, commodity chemicals, and specialty chemicals from coal- and gas-based FT processes in South Africa.
