Perspective: BTU is about the energy on the tip of a match; quad BTUs of energy is about 50 million tons of coal BTU = Energy Content* BTU = 0.25 food calories, or about the energy on the tip of a match,250 BTU = x peanut butter and jelly sandwich,42 BTU = KWH of electricity 25,000 BTU = one gallon of gasoline 20 million BTU = one short ton of coal (2,000 lbs) quad BTU = 50 million tons of coal Approximately, of course Source: Thank you to Peter J Wilcoxen, Associate Professor of Economics and Public Administration at Syracuse University for these handy comparisons: http://wilcoxen.maxwell.insightworks.com/pages/44.html

but creating new supply chains and business models (rather than pure technical efficacy) are the main challenges Proximity to waste streams Technical scale up risks Financial risks Scale in New Supply Chain Scale out Feedstock management & preprocessing Primary conversion technology Intermediate product cleanup Conversion to final product Variability - pricing Commodity risk Variability - regulations Technology risks - efficacy Proximity to offtake customers In our experience, technical efficacy has rarely been the main obstacle to MSW to biofuels commercialization. Rather, supply chain complexity, scale imbalance, regulatory and commodity risks are proving important issues.

How prevalent will Generation 2 technologies become, particularly MSW to biofuels or other energy feedstock? Generation Technology Sorting and recovery: Generation technologies sort the waste stream and recover components of value. Generation widely deployed: ~650 MRFs in the US; older dual-stream systems are being replaced by automated single-stream facilities with higher yields. Organics are important in Generation : Cities are trending towards food and yard waste bans, pushing organics out of landfills into composting and anaerobic digestion. WM has organics processing facilities. Generation 2 Technology Conversion: Generation 2 technologies focus on the chemical conversion of waste to other products (principally fuel). Development status: Generation 2 technologies are in development, but not widely deployed yet (e.g., Enerkem, Fulcrum, Agilyx, etc.). Fracturing continues: Some Generation 2 technologies will continue the trend of fracturing the waste stream and thus tend to require pre-sorting (Generation technology) for optimal use. MSW to biofuel Gen 2 technologies: feedstock supply is important: presort, recover recyclables, or take unsorted MSW?
