What is Composting?

Compost is organic matter that has been decomposed and recycled as a fertilizer and soil amendment which also serves as a natural pesticide. Compost is a key ingredient in organic farming. At the simplest level, the process of composting requires making a heap of wet organic matter known as green waste and waiting for the materials to break down into humus after a lengthy period of 1 to 2 years. Modern, methodical composting is a multi-step, closely monitored process with measured inputs of water, air, and carbon- and nitrogen-rich materials. The decomposition process is aided by shredding the plant matter, adding water and ensuring proper aeration by regularly turning the mixture. Worms and fungi further break up the material. Bacteria requiring oxygen to function and fungi manage the chemical process by converting the inputs into heat, carbon dioxide and ammonium. The ammonium is the form of nitrogen used by plants. 

Facilities We Operate

At our Compost Facility, the Lake County Solid Waste Management District composts leaves through our Leaf Collection Program which services some of the unincorporated areas of Lake County. Currently, the District has 5 leaf vacuums that collect leaves and drop them off at our facility. Once the leaves are dropped off at the site, they are immediately placed in windrows where they will begin their decomposition. These leaves are closely monitored so that our staff can determine the appropriate internal temperature to begin turning them. Once the leaves reach an internal temperature of 130 -140 degrees, they enter a baking stage. Once this temperature is achieved, there is a 15 day window to turn the pile a minimum of 5 times. This ensures proper breakdown of the material as the temperature and moisture level are closely monitored. The windrows will eventually be grinded using a horizontal grinder where they will then be screened using a Trommel screen. The Trommel screen will then produce Grade A compost that the District sells to local municipalities and landscaping companies. Compost samples are sent to A&L Great Lakes Laboratory where it is tested to ensure it is top quality compost.
