As expected, the hydrogen sulphide  odours from coal gasifi cation were  eliminated when natural gas replaced coal  as a feedstock at our Sasolburg operations.  Significant efforts are also being made to  reduce hydrogen sulphide emissions  emanating from the Secunda operation.  The sulphur recovery plants are being  upgraded to reduce levels of hydrogen  sulphide emissions and improved  monitoring and control equipment  will also be employed as part of this  long-term project.  previous year. An important contributor to this decrease was Sasol Infrachem,  where the remedial measures  implemented at our Sasol One site  in the previous reporting period resulted  in a significant reduction in waste in 2010.  Over the same period, we generated  454 kt of non-hazardous waste across  the group, 54% less than the 697 kt  produced in 2009. Contributing to this  were the reductions achieved at Sasol  Synfuels, resulting mainly from the  removal of earthworks in preparation  for the new water recovery process, and  the fact that no sulpholin liquor was  generated this year at the sulphur  recovery units due to improved  operations. Our successfully implemented  natural gas conversion project continues  to have a significant impact on the  reduction of waste produced, specifi cally  with regards to tar and oil waste and ash  at our operations in Sasolburg. During the year, we also started  implementing a number of interventions  aimed at reducing the emissions and  associated risks of VOCs. We are making  steady progress towards the achievement  of our revised and ambitious target of  an 80% reduction in VOC emissions on  the restated 2009 baseline by the end  of June 2020. The projects planned for  implementation at Sasol Synfuels from  2010 – 2013, which entail an estimated  capital investment cost of more than  R3 billion, aim to realise an absolute VOC  emissions reduction of approximately  37 000 tons annually. A further reduction  of 1 600 tons per annum is also envisaged  for Sasol Solvents.  Sasol has 3 779 hectares (ha) of land that  it owns or leases for production activities  or extractive purposes. In addition,  Sasol Mining occupies 43 941 ha of  underground mining area and 1 284 ha  of land for surface mining. In total, Sasol  rehabilitated 1 689 ha in 2010. The total  area of land dedicated for conservation  and biodiversity purposes at the end  of the reporting period amounted to  3 869 ha. We do not have operations in  areas that have been declared biodiversity  hotspots (critical or endangered  eco-regions), but we do have interests in  areas of potential sensitivity, particularly  in our upstream exploration and  extraction activities. In accordance with  our group-wide SH&E minimum  requirements, the protection of  biodiversity is addressed formally in new  projects through environmental impact  assessments (EIAs) and in existing projects  through environmental management  programmes. We are also working to  assess the biodiversity of the habitats in  We have developed various product- specific training programmes for  customers and employees. Our Sasol  Polymers chlor vinyls division, for example,  provides training programmes on the  management of different hazardous  chemicals, with a particular focus on the  handling, use and disposal of sodium  cyanide, a high-risk product used in South  Africa’s gold mining industry. Another  objective of these training initiatives is to  create awareness with regard to Sasol’s  policy on sodium cyanide which includes  the delivery of products to dedicated,  approved storage tank facilities by  trained personnel under constant  supervision, and mandatory training  for all personnel involved with handling.  We have a formalised global support  structure to ensure an ordered, group- wide response to product stewardship.  This includes a strong focus on internal  and external capacity-building activities,  particularly within our South African  business units where we have developed  various product-specifi c training  programmes for our customers and  employees. We contribute to the  development of, and will adopt, the  Globally Harmonised System of  Classification and Labelling of  Chemicals (GHS).
