Case Study: Karob Plastics – Roodeport (EnMS)

Karob Plastics is a Roodeport-based small to medium enterprise (SME) manufacturing five, 20 and 25 litre High Density Polyethylene blow-moulded plastic containers in three different shapes. Karob Plastics implemented the first phase of Energy Management System (EnMS) in 2015 as a means of reducing the company’s energy consumption.

The SME’s main energy source is electricity. The annual electricity bill approximated R3.5 million, while the usage was approximately 3.0 MWh per annum. A decision was thus taken by Karob Plastics’ top management to pursue the ISO/SANS 50001 implementation approach and sign up with the National Cleaner Production Centre of South Africa (NCPC-SA)’s Industrial Energy Efficiency (IEE) Project for the first phase of EnMS implementation.
