A notable example is Singapore General Hospital, which upcycles organic waste from its central kitchen into EcoBoost, Ento’s nutrient-rich organic fertiliser that is used in the hospital’s green spaces. Similar initiatives are gaining traction in Singapore, which is grappling with an urgent food waste challenge. Each year, the city-state generates up to 750,000 tonnes of food waste, or over 10% of the country’s total waste, data from the National Environment Agency shows. For such highly dense urban environments, embracing circular economy principles in food production offers key advantages including reduced dependence on imported farming products, enhanced cost-effectiveness of feed, and improved local food security. Ultimately, data-driven automation provides a vital pathway to addressing these sustainability challenges and shaping the future of feed and fertiliser production. By streamlining operations and facilitating the closure of waste loops, it ensures both efficiency and environmental responsibility, thereby securing a more resilient and circular food system.
