It's a state of the art project that Grand Rapids leaders say will help them achieve the city's 100 percent renewable energy goal by 2025.

The biodigester will go in at Market Avenue near the city's Black Hills neighborhood.

The project is projected to be complete in 2019 and will produce about 50 percent of the electricity the Water Resource Recovery Facility needs.
