SOUTH AFRICA (Bloomberg News)– Nampak is ramping up production of aluminium cans as Africa’s biggest producer of beverage packaging responds to consumers’ global retreat from plastic.

The Johannesburg-based company is also putting greater emphasis on cardboard cartons and developing a type of renewable plastic lid made from sugarcane, chief executive officer Andre de Ruyter said in a phone interview.

That’s due to a growing concern about the impact of plastic on the environment, particularly on items such as single-use straws.

“Consumer sentiment against plastic packaging that cannot be recycled is very clear,” de Ruyter said. “Aluminium is a valuable metal and so people have incentive to recycle it.”

Nampak and other container makers are able to boost aluminium-can production alongside expansion into fast-growing regions such as Africa, where demand for canned and bottled drinks is rising as people start to buy packaged goods for the first time.

Nampak is spending R100m on a new food-can line in Nigeria, while that country’s GZ Industries is opening a factory in South Africa.

Nampak shares declined 5.1% to R14.75 as of 15:40 in Johannesburg, after the company announced a 7% rise in full-year operating profit.

The firm resisted a resumption of dividends due to a long-standing issue transferring cash from Angola and Zimbabwe and an ongoing effort to sell its glass business.
