  1. Sustainability Institute Department of Natural Resources and Environment An Integrated System to Provide Bedding, Manure Composting and Energy and CO2 for a Greenhouse Operation Heat and CO2 to Greenhouse Woodchips Wood Shavings http://attra.ncat.org/images/solar-gh/solar_greenhouse.gif Compost Woodlands Bedding/ Manure Bedding

  2. Sustainability Institute Department of Natural Resources and Environment First Step: Sustainable Harvesting of Low Quality Softwoods Measured Productivity and Biomass - About 40 hectares of manageable, low-quality old field woods - Need to harvest .4 hectare/year or 1/6th of total annual wood production

  3. Sustainability Institute Department of Natural Resources and Environment Second Step: Producing Bedding from Harvested Wood Data show yield of 3 “cords” of shavings for 1 “cord” of wood (1 cord = ~ 4 m ) 3

  4. Sustainability Institute Department of Natural Resources and Environment Third Step: Bedding Used in the Barn

  5. Sustainability Institute Department of Natural Resources and Environment Fourth Step: Composting the Bedding/Manure Mixture: A High-End Research Facility

  7. Schematic Diagram of the Operation of an Aerobic Composting System for Energy Capture 1. Blower pulls air through compost 2. Hot, moist air passes over isobars heat captured in phase change to gas in isobars 3. Heat transferred to bulk water tank as phase change back to liquid in isobars 4. Hot water used for heating, washing, etc. 2 3 1 4

  8. Schematic Diagram Energy Capture and Transfer using AGRILAB Isobar system

  9. Sustainability Institute Department of Natural Resources and Environment Floor of Composting Facility with PVC Pipes Embedded in Concrete under Marine Plywood Strips PVC pipes with drilled holes under marine plywood strips

  10. Sustainability Institute Department of Natural Resources and Environment Pipes embedded in concrete floor penetrate headwall Air drawn from pipes into manifold and drawn into isobar assembly

  11. Sustainability Institute Department of Natural Resources and Environment Air from compost in manifold drawn in and across isobars embedded in bulk hot water tank

  12. Sustainability Institute Department of Natural Resources and Environment Isobars Being Installed in What Will Be the Hot Water Storage Tank

  13. Sustainability Institute Department of Natural Resources and Environment Hot water is drawn from the storage tank for use in water heating for cleaning in the milking parlor

  14. Sustainability Institute Department of Natural Resources and Environment The Future: Energy and CO2 for a High-Tunnel Greenhouse Operation Compost Number of composting operations Growing rapidly in New England http://www.farmtek.com/wcsstore/EngineeringServices/allbizunits/prodimages/zoom/1x/103083d.jpg
