Innovative IoT solution helps Emerson Grind2Energy turn food scraps into fuel

Remote sensors optimize slurry tank pump-outs, decrease fuel costs and help customers quantify their environmental sustainability efforts

In Brief

About Emerson

Grind2Energy™, Emerson’s food waste recycling initiative, helps large food waste generators such as supermarkets, hotels and hospitals minimize their environmental impact and boost their operational efficiency. The system uses industrial-strength food waste grinders to process food scraps into a liquid slurry that is pumped into on-site holding tanks and later converted to biofuels and fertilizer.

Food Waste Recycling



Business Challenge

Emerson engineers developed Grind2Energy to cut down on the amount of food waste in U.S. landfills. The system enables venues with large food service operations to process food scraps and store the resulting slurry in onsite tanks. Grind2Energy wanted to keep an eye on the slurry tanks so it could dispatch trucks to pump out the tanks only when they were almost at capacity. It also wanted to better schedule preventive maintenance and provide its customers usage and sustainability reports.


Emerson uses an AT&T Internet of Things (IoT) solution to monitor slurry tanks so it can more efficiently schedule pump-outs, repairs or preventive maintenance, saving truck fuel and driver hours. The IoT capabilities also enable Grind2Energy to provide near real-time environmental sustainability information, performance reports and data analytics to help customers document their efforts to comply with environmental mandates.
