Compost Products
While most companies use trammels with 1 inch screens, the owners of NorthWest were looking for a way to stand out from the competition while improving the industry and upgrading the performance of their compost products. The advantages of using a finer compost is that it can absorb and blend with the soil with greater ease in a shorter period of time, causing the soil to rich and break down at a faster rate. We use half inch screeners to deliver the highest quality and finest compost to your front door.

Separated Solids
Cleaner products from dairy cows, the manure is washed off with water and sent into a separator. After separating the product from the water, improving the PH balance (for nurseries and vineyards) it is then put through the same turning and rotting process as regular steer manure compost.

Centrifuge Steer Manure
This type of compost is a nitrogen-rich low salt content manure compost. Separating solids and liquids in the process. The salt remains in solutions removing the before composting products. The solid waste is then formed to windrows and turned to meet the Washington State Dept. of Agriculture organic requirements.
