Cedar Grove Composting is the sister company to Emerald Services. We are a family owned company that has roots in the waste management industry dating back to 1938.

Cedar Grove ® is an environmental solutions company. We harness the vitality of organic waste by recycling it into innovative products. In doing so, we energize cities, businesses and citizens to be a force for good by coming full circle with their organic waste. We play an important role in diverting organic waste from landfills. From two local facilities, we compost over 350,000 tons of residential and commercial yard and food waste annually.

3. We’re developing ways to generate renewable energy from organic waste.
4. The products we make improve air, soil and water quality.
