PepsiCo has spent $37m upgrading its Regency Park manufacturing facility in South Australia.
Over the last three years new technology has been installed and legacy equipment replaced to increase capacity and improve environmental performance.
The site employs 285 people and processes 60,000 tonnes of potatoes a year to make snack foods including Smith's and Red Rock Deli potato chips.
The plant also manufactures Doritos, Twisties and Sunbites brands.
For PepsiCo ANZ CEO, Danny Celoni, using local manufacturing, employment and produce are "incredibly important" to the company.
The company has been manufacturing at the Regency Park site for more than 35 years, he said.
PepsiCo purchases 40,000 tonnes of potatoes from South Australian farmers every year, which sees the Regency Park plant wash, slice and cook around 88,000 potatoes an hour.
"A third of the potatoes we use nationally are sourced from South Australia, these farmers are an integral part of our business," Celoni said.
The plant revamp also saw solar panels installed, which generate 830,000 kWh, or roughly eight per cent of the plant's electricity consumption.
The plant has reduced its water consumption by 65 per cent since 2006. This year, the company increased its recycling of production waste to 96 per cent.
The South Australian minister for trade, tourism and investment, David Ridgeway, said that investments like PepsiCo's were "essential" to the state's economy.
