In-sink Garbage Composter

We waste 1.4 billion tons of food in the world every single year. In the United States alone, 80 billion pounds of food a year goes to waste, which means every person generates 219 pounds of waste on average. To put things into perspective, just imagine every single person in America throwing more than 650 apples into the trash, and most of this waste goes straight into landfills. For this project, we want to tackle one of the most important and pressing global issues: food waste. While there are established composting facilities, most food waste from households still directly goes to landfills. There are mini composters on the market, but they are expensive, take up a lot of space, and involve extra steps of filtering out and putting compostable waste into the machine, which is inconvenient and time-consuming. Our proposed solution is to integrate an in-sink garbage disposer with a composter. In our vision, users can just throw food waste into the sink and let the composter does its job. The processed compost can be directly dumped into the garden to fertilize home-grown vegetables or fruits, completing the food cycle. Our solution aims to change every household’s lifestyle by transforming trash into treasure.
