Johnson Matthey, a British company established in 1817, is a global manufacturer of automotive components, specifically autocatalysts.
In response to the increase in energy costs, JMSA Germiston signed up with the IEE Project in 2012 as a candidate plant for the implementation of an ISO 50001-based energy management system.
As part of the implementation of ISO 50001, four main projects were identified as potentially large energy savers. Three of these, namely the air compressors, chillers and mixing vessels, could be implemented immediately with nominal or no investment required. The fourth project was the optimisation of the ovens, which was implemented as phase two, during the December shutdown period. These four projects resulted in approximately R4.5 million savings (USD 330,000).
