North Mason Fiber intercepts unwanted land clearing debris, yard waste, waste fish products and construction wood debris that would normally have been burned or buried in landfills, and converts it to super rich, clean compost and soil materials.

North Mason Fiber is the only permitted facility on the Kitsap and Olympic Peninsulas to produce truly organic compost, certified by the Washington State Department of Agriculture. This organic certification assures you that our material is free from undesirable chemicals and foreign debris.

North Mason supports local retailers with the sale of our high quality bagged products: Oly Mountain Fish Compost and Oly Mountain Organic Compost. All of our products are locally produced, from locally sourced materials.
