Jeremiah's Cornerstone System is used in his vermicomposting business. He composts food waste from schools, restaurants and breweries, mixed with horse manure and wood chip bedding from three stables. Jeremiah was looking to reduce the machinery costs for upfront capital needs. His O2Compost system allows him to operate with just a skid steer in a smaller area (no need for windrows, tractors or turners). The finished compost product is sold both wholesale and retail. Jeremiah says "The team at O2Compost has been extremely helpful through the process of creation, implementation and support with the process. My only wish ... I could see into the future and created a slightly bigger system as we have grown quickly."
