  2. Distributed Bioenergy Solutions Onsite systems typically serve small and medium sized facilities, communities, and organizations with 50 – 50,000 people. They can save resources in a number of powerful ways: saving money for disposal, energy, landscape, and food simultaneously. • Elimination of hauling and disposal of foodwaste, foodservice paper, landscape waste, and woodwaste. • Creation of renewable energy onsite. • Creation of new soil, fertilizer, and sequestered carbon for landscaping, horticulture, and food crop production – at a local and community scale.

  6. Farm-to-Table Facts • Urban farming and community gardening is blossoming in North America. – In one city a population of 650,000 supports 88 community gardens, 31 acres of food production, and 6,000 active gardeners. • Farm-to-table businesses, slow-food projects, and 100- mile-diets are all part of community supported agriculture. – These programs are also expanding. • Some operating precepts: Food to renewable energy to soil to new food Consumers (you) are making a choice to be an active, proactive, and informed part of the food chain.

  7. Benefits of Bioenergy • Supply onsite building heat, hot water, lighting, electricity, and/or vehicle fuel to host facility or adjacent properties • Managing organic waste on the property ` – ( minimizing the export of waste materials) • Connect with urban agriculture and renewables movements – ( minimizing the import of manufactured and processed food ) • Increase system diversity and reliability by deploying a local, distributed renewable energy system – ( minimizing the import of energy and fuel ) • Build jobs and commerce within the community – ( minimizing the export of dollars )

  17. Example: Greenerzone BC • Service area population of about 150,000 – Langley BC area • Enterprise Curbside Organics Collection – – Private Contractor – Approximately 36,000 kg/year diverted from disposal – Potential to divert 100,000 kg/year from disposal • Extracting Energy – HORSE Bioenergy System • Converting Organics to Soil Products – CITYPOD, Dehydration, Vermicomposting and Field Composting • Partnering with Field and Hothouse Growers • Partnering with Vermicomposting, Urban Food Hubs

  18. Greenerzone BC The HORSE can save resources in a number of powerful ways by saving: money for disposal, energy, chemical inputs to the landscape, and costs for food simultaneously. • Elimination of hauling and disposal of foodwaste, foodservice paper, landscape waste, and woodwaste. • Creation of renewable energy onsite PLUS creation of new soil, fertilizer, and sequestered carbon for landscaping, horticulture, and food crop production at a local and community scale, PLUS • Cost Savings and reasonable ROI • Quick Deployment • Low Capital Cost • Scalable Design • Odor Control • Easily marketable biocarbon products

  19. Example: Zero Waste Vashon • Island population of about 10,000 – King County WA • 501 c 3 Non profit – Focus on organic waste which can be better managed and processed. Goal of ZWV to honor green materials as a resource. Organic waste should be converted locally in an island-located facility. – Complementary technologies include anaerobic digestion, passive and active solar, biosolids, and biochar. – Approximately 8,000 tons/year currently exported to landfill disposal. – Potential to divert about 5,000 tons/year in an island-located facility. • Extracting Energy – AD • Converting Organics to Soil Products – Composting and Wood Gasification • Co-locating Field and Hothouse Food Production

  20. What Are the Success Factors? � Cost Savings and reasonable ROI � Quick Deployment � Low Capital Cost � Scalable Design � Odor Control � Easily marketable biocarbon products
