About Us

As an industry-leading environmental solutions company, Cedar Grove harnesses 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.

Cedar Grove also plays an important role in diverting organic waste from landfills. At two local facilities, we compost more than 350,000 tons of residential and commercial yard and food waste annually.

Using nature as our guide and proven technology, we're responsible for transforming waste materials into inventive products that benefit our community. We divert supposed "waste" that would otherwise be mixed in with trash and shipped to landfills and transform it into clean, nutrient-rich products.

Our Actions:

1. We’ve helped to increase urban recycling in the greater Seattle area.
2. We’re decreasing the amount organic waste that goes into landfills.
3. We’re developing ways to generate renewable energy from organic waste.
4. The products we make improve air, soil and water quality.



In 1988, the City of Seattle came to us and asked for our help in recycling the organic yard waste collected curbside. We jumped at the opportunity. Having been in the waste management and recycling business since 1938, we knew it was the last frontier of recycling. We felt a sense of obligation to our city, our business, and of course, the environment.

Since then, we’ve made huge strides in organic recycling—as a company and as a region. In 2004, we started accepting food waste.

We believe in investing in the best technologies available—in the world. We search far and wide for state-of-the-art equipment that produces measurable results, and our diligence continues to pay off.

We utilize GORE® Cover and the OdoWatch™ system. These technologies help us continue to lead the way in waste recycling, odor management and the creation of renewable products.
