Abstract
South Africa’s increasing cost of industrial energy
has recently caused the country to be ranked among the top five
countries in the world with the most expensive industrial
electricity tariffs. For various reasons, energy is often not
optimally used in industry. According to Zavanella and Zanoni
(2009), there has been a growing interest in more rational and
responsible consumption of energy, especially in industrial
processes and services. This research study demonstrates the use
of technology for energy efficiency in the industry, in order to
reduce energy consumed per unit produced on industrial process
plants.
