From the start, Rock River Valley Compost’s goal has been to lead the way in residential and commercial recycling and disposal. We accomplish this through composting – the transformation of organic material (plant matter) through decomposition into a soil-like material called compost. Composting is a natural form of recycling, which continually occurs in nature. After the yard waste is ground at our facility, it is deposited in windrows where it goes through the composting cycle. Once the finished compost is screened, it is sold to and widely used by home gardeners and landscape professionals.
