In England, around a quarter of all waste is generated by commercial and industrial (C&I) businesses. The hospitality and food sectors, including hotels and restaurants, are major contributors. But businesses such as food manufacturers, retailers and even healthcare providers all add considerable weight to a burgeoning fatberg of waste. And much of it is avoidable. In hospitals, for example, 121,000 tonnes of food is thrown away each year and 75% of it could have been eaten. Food waste costs the NHS around £230m each year. Let that sink in.
