What Is Compost?

Compost is an organic product created through the controlled decomposition of biodegradable materials.  As the materials decompose, they reach a high temperature of up to 160 degrees Fahrenheit, which significantly reduces pathogens and occurrence of weed seeds.  Compost is typically used as a soil amendment and contributes to plant nutrients.


Composting Process:

Green waste, including tree branches, grass clippings and leaves are placed in  windrows, turned, and composted for about 12 weeks.  During the 12-week process, windrows are turned 5-7 times, ensuring organic materials reach a temperature of at least 132 degrees for 15 days. These high temperatures ensure that any weed seeds or unwanted pathogens are killed off.

After the windrow process is complete, the compost is then run through a trommel screen in order to separate fine and coarse materials.  The fine material is sold as our USCC certified compost product.
