 Enevo (Enevo Oy in Finland) is a Finnish provider of wireless sensor networks that measure and forecast fill-levels of waste containers in order to optimize collection intervals and routes based on this data.

The company estimates that it can reduce waste collection costs by up to 30%.Enevo was founded in 2010 and is led by Fredrik Kekäläinen and Johan Engström.
