As much as 34.3% of local food production in SA is being lost or wasted, says the Council for Scientific & Industrial Research . Factoring in that SA is a net exporter of food, this climbs to 45% of the available food supply , it found in a May 2021 survey. That’s 10.3Mt of food a year that never ends up feeding people.
Using AI and other data analytics, potential food wastage hotspots are optimised. In its delicatessen section alone, Shoprite has been able to bring down waste by 11%. “Waste occurs across the supply chain, from farm to fork. It is a complex issue. Reducing waste at the source of the retail process is the best option, therefore the group has adopted AI and machine learning to optimise its ordering and replenishment processes to reduce surplus food and ultimately food waste.”
Shoprite aims to not send any organic food waste to landfill by 2025, and has found smart alternatives. “Every week the group sends about 44t of food waste, mainly dried goods such as pasta, cereals and flour, to be converted to animal feed,” says Raghubir. Customer demand is dynamic and can change quickly, and AI and machine learning enables the group to improve its prediction of sales, and order accordingly
