Lower food waste Smith said the rate of food waste for Ocado stood at just 0.04% in 2020, which is significantly better than the average rate of food waste for other supermarkets, which ranged from 2% to 5% last year. The Ocado boss said the reduction in food waste makes a big difference to the bottom line and profitability of the company. Based in the UK, Ocado has grown to become one of the world's largest online grocery companies. However, the company aims to make most of its money by licencing its online grocery technology to traditional supermarkets that do not have a strong online platform. In recent years, Ocado has signed technology partnership deals with supermarket chains such as M&S, Morrisons, Groupe Casino in France, Sobeys in Canada and US supermarket giant Kroger.
