Why waste? Scope of the Problem/Opportunity Diversion vs. Conversion Garbage in … Energy out CIWMB Survey of leading technologies Profile: Gill’s Onions Biorefineries What now? Q & A Trash is a terrible thing to waste! 3. Why Talk About Waste? It’s cheap, abundant, local Mostly an afterthought Reflects linear design Can be repurposed, redirected, recovered Nature constantly recycles Take Make Waste inefficiency Waste equals Food! 4. Well, maybe 5. Linear US Industrial Processes Take Make Waste 80% of products discarded after single use 99% of original materials used or contained in US manufactured goods become waste within 6 weeks of sale Waste is created faster than it can be reconstituted back into useful resources (such as soil nutrients or energy) Raw Materials 6% Product 94% Waste Manufacturing Process 6. Why Use Waste for Energy? Breaks our dependency on centralized energy Disrupt the Fossil Folly! 7. Advantages of Converting W2E Eliminates disposal costs for the producer Can become a profit center via (resource efficiency & productivity) Commensurate reduction in air pollutants Green jobs & marketing (bragging rights) Feel-good factor; responsible, sustainable Does W2E help municipalities reach diversion goals? 8. Why we waste waste Because we can Initial capital costs … ROI can take years Perception of risk: Who will buy it? At what price? (Energy “price shocks”) It’s messy, often smelly, volatile/dangerous … More important things than taking out the garbage 9. INDUSTRY HOUSEHOLDS EVERYWHERE! Common forms Municipal Solid Waste (MSW): human & pet Greenwaste – yard trimmings, etc. Construction / demolition wastes Kitchen / table scraps & other compostables Legally dumped industrial wastes Illegally dumped … Garbage In … Where DOES It Come From? 10. Agricultural crops, aquatic plants Agriculture / aquaculture wastes & residues Wood, wood wastes & residues Animal wastes (manure, tallow) Restaurant & institutional food service waste (yellow grease) Garbage In … Definition: BIOMASS Any renewable, organic matter 11. Agenda … Energy Out 12. California Organics Disposed (28,000,000 tons per year; CIWMB) 13. Disposal vs. Landfill Diversion (CIWMB) 14. Diversion and Conversion Energy from Waste Recovery Diversion Composting Chipping/Grinding for Mulch Reuse/Recover Recycling Conversion Thermal: incineration, gasification, pyrolisis Non-thermal: anaerobic digestion, fermentation Physiochemical : synthetic crude oil or biodiesel 15. Survey of conversion technologies for municipal solid waste (MSW) to energy Motivation: Many CA jurisdictions concerned with landfill capacity and difficulty of new sites Los Angeles, Santa Barbara, Sacramento, San Jose, Santa Cruz, and others 23 responses from 83 survey requests Municipal Solid Waste to Energy Survey 2009 ciwmb.ca.gov/Publications/Organics/2009008.pdf 16.

Facility Development Stage Laboratory Permitting / Construction Small Pilot Large Pilot Commercial- Scale Demo Commercialized 3 6 2 4 4 5 18. Commercial Activity 19. Thermal (thermochemical) Higher temperatures and conversion rates Emissions concerns A continuum of processes Pyrolisis : Thermal decomposition in a primarily non-reactive environment Gasification – Decomposition in a chemically reactive environment Autoclaving – Separation of compounds through combinations of heat and pressure 20. Biochemical Conversion Anaerobic Digestion, Composting, Fermentation Relatively low temperatures & lower reaction rates High selectivity for products Higher moisture feedstocks Not applicable to non -biodegradables (such as conventional plastics) 21. Cellulosic biohols – waste, weeds, or wine – may get us out of this pickle 22. Proven Method: Gasification Anaerobic Digestion Municipalities and private ventures use it. Gasification produces … METHANE – affordable renewable energy (burned to generate heat & electricity) COMPOST – returns nutrients to soil 23. Physicochemical Conversion Biodiesel liquid fuels Near-ambient temperatures and pressures Synthesis – both physical & chemical Primarily used to transform fresh or used vegetable oils, animal fats, greases, tallow, and other feedstocks 24. 25. The biofuels industry is expanding faster than it is maturing 26. BioEnergy New Energy Pond Scum Energy Forms: Advantages: Cleaner-burning gases Replaces dirtier fuels Electricity co-generation Commensurate from methane gas reduction in GHG Liquid Biofuels Elim. hauling costs Storage in fuel cells Available when needed W2E FutureTech 27. Energy Beets Turning beets into methane & electricity WISE Solutions increase simple sugars WiseSolutions.net sugarbeet.ucdavis.edu Mendota Beet Coop & UC Davis 28. 29. Onion Juice goes to anaerobic digester to produce CH4 (methane) CH4 burned cleanly to power 600 kilowatt fuel cells -- enough to run 460 homes 30. Gills Onions Why they did it Saves $700,000 / year in electricity Reduces 225,000 lbs solid waste per day Saves additional $400,000 disposal costs Break-even within 6 years Elim 30K tons CO2-equivalence per year “ It was first a business decision to solve a waste problem.” – Steve Gill 31. Pond Scum Economics: The race is on! Algae Farming in New Zealand 32. Industrial Biorefining 33. Success Keys in BioRenewables All ag waste / biomass = opportunity Radical innovation … get disruptive! “ Biorefinery” yield multiple $ streams 34. Investing in radically innovative BioRenewable technologies Bioplastics & green chemistry business development since 1996 Services: Workshops and seminars Market, competitive & risk analysis Deal structure and presentation coaching Commercialization and technology transfer / licensing Management consulting, team facilitation, project management More at in3inc /about.html What We Do In spire In novate In vest 35.
