Nampak plans to double production capacity at its glassmaking unit by January next year as it seeks to become a more dominant player in South Africa.

The company would add a third furnace to its existing glass production line at a cost of R1 billion ($112.3 million), doubling the capacity to 200,000 tonnes, Nampak investor relations manager Graham Hayward said.

“We have a 20% market share on the glass side in South Africa. Some customers want us to become a bigger supplier,” he said.
