2007 in numbers At the Seal Sands site, most health, safety and environment aspects relate to the use and emission of organic solvents, energy consumption as well as the risk of work-related accidents. In 2007, the emission of organic solvents was close to zero and energy-saving efforts have resulted in a seven per cent reduction in energy consumption. Production and consumption Production rose by eight per cent, while the consumption of raw materials rose by 14 per cent. The higher raw material consumption is made up by a fall in the consumption of solvents of around two per cent and a 32 per cent rise in other materials. This is partly due to the work to recover solvents, but mainly because chemical processes differ from year to year. Depending on the type of reactions and number of production steps in the manufactured products, the consumption of material changes. In 2007, we produced a higher volume of the products that use less solvents and more of other materials.

This was made up by a five per cent decrease in electricity consumption and a decrease of about eleven per cent in gas consumption. A focused effort on energy savings has resulted in several process optimisations. The refrigeration systems, the LT and the LLT, have been optimised so that they cool only when needed and only down to the necessary temperature. In addition, the VOC absorber that uses gas to make steam has also been optimised. Both improvements have resulted in energy savings.

One of the reasons for this reduction is the work performed to recover solvents. In 2007, recovery of toluene contributed to an eight per cent reduction in chemical waste, which forms part of the total waste volume. In 2007, we also focused on a reduction of the amount of waste for landfill. The efforts made to divert waste away from landfill resulted in a 29 per cent reduction in this waste type.

The main reason for the reduction is the renewal of the carbon in the adsorption beds of our abatement system. New carbon leads to a higher adsorption rate. In 2007, the number of annual samples taken to analyse our emissions increased from four to twelve. More samples improve the data quality and in this case showed a lower emission than what we found in previous analyses.
