    1. 1. Next-Generation Organics Management<br />High Solids Anaerobic Digestion in Massachusetts<br />
    2. 2. 2<br />About Harvest<br />Harvest, a Massachusetts-based company, is ushering in a new era of organic waste management by harvesting the renewable energy and soil-building potential in organic waste at its state-of-the-art organics recycling facilities.<br />Corporate Profile<br />Builder, owner, and operator of organic waste processing facilities<br />Recognized industry-leading experience in organics waste management<br />Financial investments from Kleiner Perkins Caulfield & Byers, Generation IM, Munich Venture Partners, and Waste Management <br />150 employees<br />Expanding technology portfolio supported by industry-leading science and technology advisors  <br />
    3. 3. Fraser Richmond Soil & Fibre <br />Near Vancouver, BC, one of the largest, most efficient composters in North America<br />Largest yard and food waste composting facility in Canada<br />Under construction of North America’s first commercial-scale HSAD facility to increase capacity and process the region’s growing SSO stream<br />Urban Wood Waste Recyclers<br />Metro Vancouver’s largest recycler of urban wood waste, achieving the highest levels of land fill diversion in the region<br />Expanding production of coal-replacement fuels<br />Tulare<br />Large windrow operation in Tulare County, CA<br />100% of end product goes into high value agriculture<br />Tullytown<br />Operating windrow facility at WM landfill site<br />Soon to be upgraded with Harvest’s proprietary composting technology<br />London Ontario<br />North America’s largest merchant AD facility<br />Using LSAD technology<br />Operational year end 2011<br />3<br />About Harvest<br />Operating Facilities<br />
    4. 4. 4<br />Technology Selection is Driven by Feedstock Characterization<br />That’s why Harvest is under development on high solids anaerobic digestion (HSAD) and low solids anaerobic digestion (LSAD) projects. The technology choice largely depends on the feedstock characteristics:<br />The choice is also dependent on the availability of wastewater reuse options (farms, WWTPs, etc.), as LSAD results in wastewater discharge.<br />

    6. 6. SAMPLE 30,000 TONS PER YEAR HSAD FACILITY LAYOUT<br />6<br />Technology<br />
    7. 7. 7<br />Technology<br />HSAD – Advantages<br />Process yields biogas with average methane content of 70% to 80%, considerably higher than many other HSAD technologies. Less biogas cleaning and processing required.<br />Process design allows for a maximum feedstock residence time of woweeks, increasing processing capacity and reducing facility footprint<br />No grinding, slurrying required; only moving part is front-end loader; entire process controlled by computer.<br />BiogasPurity<br />Residence Time<br />Operational Requirements<br />
    8. 8. 8<br />Technology<br />HSAD – Advantages (2)<br />AD process naturally breaks down many of the volatile compounds that cause odor; system under negative pressure with air ventilated through biofilter, eliminating VOCs; facility is totally enclosed.<br />Large portion of leachate is re-circulated to aid in digestion and gas yield; the remainder may be used in compost process.<br />Very low parasitic energy use of <5%; requirements can be met completely with energy generated on-site.<br />Odor Control<br />Water Usage & Leachate Control<br />Energy Requirements<br />
    9. 9. 9<br />Reference Facilities<br />HSAD FACILITIES<br />Harvest’s HSAD technology partner GICON has built 30 biogas facilities in Europe, and we recently started construction on an HSAD facility at Fraser Richmond Soil & Fibre, our 300,000-tpy composting operation in Richmond, BC.<br />Cottbus R&D Facility<br />
    10. 10. 80,000 TONS PER YEAR LSAD FACILITY LAYOUT<br />10<br />Technology<br />
    11. 11. 11<br />Technology<br />LSAD – Advantages<br />Can process a wide variety of typically challenging organic wastes including SSO, grease trap contents, food processing residuals and Dissolved Air Flotation residuals (DAF)<br />Has a long track record of operational success with thousands of facilities in operation<br />Continuous process allows for optimal use of infrastructure<br />Feedstock Flexibility<br />Technology Dependability<br />Infrastructure Utilization<br />
    12. 12. 12<br />Technology<br />LSAD – Advantages (2)<br />A large number of technology suppliers exist, increasing competition and reducing facility costs<br />Less feedstock seasonality allows for more consistent operation<br />Consistent energy production due to continuous feeding process<br />Market Maturity<br />Operational Consistency<br />Energy Production Consistency<br />
    13. 13. 13<br />Reference Facilities<br />LSAD FACILITIES<br />LSAD is a proven technology in North America and Europe. Harvest’s LSAD technology has experience in many different types of anaerobic systems, all of which are optimized for certain applications, duties or design objectives.<br />Cottbus R&D Facility<br />
    14. 14. London Project Overview<br /> Harvest is breaking ground on a 80,000-tpy LSAD facility in London, Ontario. The project details for this facility are shown below.<br />14<br />
