St. Cloud Hospital uses food waste as fertilizer

The hospital experimented with the idea two years ago and was surprised by its success.

St. CLOUD, Minn.—Flower gardens surrounding the St. Cloud Hospital could bloom a little brighter this year with the help of fertilizer produced from waste food.

The hospital installed a system to grind and dehydrate waste food about two years ago. Instead of going down the drain, the food is run through a pulping machine, then dried. The material is reduced by about 96 percent in the process.
