We designed Mill to dry and grind food scraps as efficiently as possible using integrated sensors and custom algorithms that determine the quickest runtime needed to transform your food scraps into dry grounds. Your energy use will depend on the amount and kind of kitchen scraps you add to it. We estimate the bin will use around 1 kilowatt-hour (kWh) of electricity per day, averaged over multiple weeks of usage (if you generate around 1.5 lbs of kitchen scraps per day). Today, that’s about the same amount of energy per day as an energy-efficient dishwasher, but with software updates, the bin will keep getting better and more efficient over time.
The cost of energy will depend on your local energy rates — you can check your energy bill to see how much you pay per kilowatt-hour (kWh). At $0.20 per kWh (approximately the national average), that’s about $6 per month.
Want to use less energy? Try limiting liquids by doing things like straining wet foods before adding the solids to the bucket.
Big picture: based on our preliminary study, you can avoid about a half-ton of greenhouse gas emissions per year with a Mill service plan. Instead of filling the air with methane, your kitchen scraps are turned into food for chickens, going right back into the food system.
