Our GTL diesel has a higher quality than diesels derived from  crude oil. GTL diesel has a high cetane number (70+ versus  the conventional 45 – 55), low sulphur (less than fi ve parts  per million), low aromatics (less than 1%) and excellent  cold-flow characteristics. Our GTL diesel, therefore, is ideal  as a low-emissions, premium grade fuel and as a blend stock  for upgrading conventional diesels. o Markets Sasol markets products directly  to the consumer, as well as to  commercial and industrial customers,  thereby integrating its upstream  and downstream activities. Innovation Research  Water New energy  Various technological advancements in effl uent  recycling, cooling, pre-treatment of water  for steam generation and solids handling are  paving the way for signifi cantly improved  zero liquid effluent discharge designs, which  are being developed irrespective of water  availability or pricing. Sasol New Energy Holdings (SNE) was created to focus on new  technologies that can be integrated with our core technologies  to reduce our GHG footprint. As part of our commitment to reduce  production of carbon dioxide in our operations and integrate new  technology into our FT processes, SNE will look into renewable  and lower-carbon energy options such as solar, biofuels and biomass,  as well as nuclear, hydro and natural gas.  In downstream chemical process technology, we have developed  several proprietary processes for recovering and processing a range  of solvents, waxes and phenolics for the world market, as well  as 1-pentene, 1-hexene, 1-heptene, 1-octene and higher alpha  olefins, the last of which we convert into Safol™ H(C$_{12,13}$) alcohols.  We have developed and patented several base-metal catalysts  for our FT synthesis processes. We have also been innovative in coal exploration and mining, where  Sasol Mining (sometimes in partnership with technology suppliers)  has developed high-extraction mining methods, advanced  directional drilling techniques, roof-bolting systems, continuous- miner systems and a virtual-reality training system for continuous- miner operators, among other cost-saving innovations. Besides the research and development and new-product  formulation and testing work we do at Sasolburg through Sasol  Technology’s fuel research group, we conduct further fundamental  research at the Sasol Advanced Fuels Laboratory (SAFL), in  collaboration with the University of Cape Town, and the Sasol Fuels  Application Centre (SFAC). SFAC enables us to conduct sea-level  engine and fuel research and tests in line with international trends.  and to exceed targeted rates of return in a sustainable manner. 5 annual review 2010 • our business •  our integrated business model
