You probably don't spend much time thinking about food waste, but as experts in food waste, we think about it a lot. Food waste is a big problem - in Australia over 7.6 million tonnes of food is wasted each year (Foodbank). Food waste in landfill produces methane, a dangerous greenhouse gas that is a known contributor to climate change. In fact, methane is 21 times more dangerous than carbon dioxide. While there's no single solution for reducing the world's waste, even the little things we do can have an important impact on the environment - like using as InSinkErator food waste disposer to keep your food scraps and waste out of landfill. Finely ground particles from the InSinkErator are connected to the wastewater (sewage) system, and treated at wastewater treatment plants, where the wastewater is converted to various classes of recycled water.
