ReNutri integrates environmental protection into everyday life through an intuitive and hygienic urban food waste recycling system and a drying bin. Designed to fit users’ daily habits, it encourages greater participation in food waste recycling, returning waste to the ecological cycle and contributing to a greener future where both people and the environment benefit.
Food waste is a reusable resource. However, according to the Ministry of Environment, over 60% of food waste in 2023 did not enter effective recycling systems. Around 800,000 tons were sent to landfills or incinerators each year. The high moisture content of food waste reduces incineration efficiency and may produce harmful substances, leading to environmental pollution, higher treatment costs, and wasted resources. Although many cities are promoting food waste recycling, issues such as poor sorting, limited processing methods, and difficulty in changing user habits continue to hinder effective reuse.
ReNutri targets environmentally conscious individuals constrained by time and convenience. We offer a food waste recycling service that fits daily routines. After subscribing to the service, users receive a dehumidifying drying bin for home use. Once full, the dried waste can be conveniently dropped off at automated recycling machines located at partner supermarkets during weekend shopping trips. Food waste from users and supermarkets is then transported to ReNutri recycling centers, where it is sorted and handed over to black soldier fly biotech companies for conversion into insect meal and frass, which are sold to farmers and aquaculture businesses. Users earn points for every drop-off, redeemable for supermarket products and viewable in the app along with their personal carbon reduction data.
