8 January 2013 – Electricity accounted for 6% of JSE listed pharmaceutical group Aspen’s production cost in its 2012 financial year, down from 7% the previous year. This was the result of a number of energy efficiency projects including the replacement of all the high wattage lamps in its quality control laboratory in South Africa with energy efficient lamps. It also retrofitted lights and installed motion detectors in the administration office area in Port Elizabeth, South Africa, whereby lights are automatically switched off after a set period when the area is not in use.
At the company’s Port Elizabeth Sterile factory, manual load control was introduced to operate six HVAC chiller units. This ensured that the chillers were operated only in response to the instantaneous HVAC load requirements. The success of this intervention validated the purchase and installation of an automated chiller control system to reduce unit consumption in relation to demand. Timers were installed on six geysers at the East London site to ensure these were only operated when required.
In Kenya, energy saving lights were installed at Beta-Healthcare to reduce electricity consumption.
The company said in its 2012 annual report that owning to the high risk of power outages in Africa, back-up generators have been installed to support continuity of IT systems and in core areas of its Sterile facility in Port Elizabeth. Back up generators are also being used in core manufacturing areas at the company’s East African sites.
