- Producing Energy and Fertilizer From Organic Municipal Solid Waste -- Project Deliverable #1, Usama Zaher, Dae-Yeol Cheong, Binxin Wu, and Shulin Chen, June 2007. A literature review of current digester technologies formed the framework for designing a bench scale study of a high solids anaerobic digestion (HSAD) system. The study shows that significant improvements in methane production can be attained while decreasing capital costs for facilities. A new digester design is proposed that will optimize methane from organic food and green waste digestion, while recovering nutrients from the digestate.
- Organic Waste to Resources Research and Pilot Project Report: Producing Energy and Fertilizer from Organic Municipal Solid Waste: Enhancing Hydrolysis and Bacterial Populations and Mixing and Thermodynamic Modeling of New Solid Waste Treatment Technology, Usama Zaher, Shulin Chen, Chenlin Li, Liang Yu, and Timothy Ewing, June 2009. This project developed, tested and modeled a high solids anaerobic digester consisting of a solids reactor and a leached liquids UASB for reacting volatile fatty acids. At near neutral pH the system improves methane production 50% over existing digesters, while return flow reseeds the solids digester with high titer micro-organisms that improved biological kinetics. The dual reactors system provides for control of digester limiting acid and ammonia processes, while allowing for nutrient recovery, and significantly improves performance for capital outlay.

Organic Waste to Resources Research and Pilot Project Report: Use of Biochar from the Pyrolysis of Waste Organic Material as a Soil Amendment (September 2009) - Biochars from different feedstocks were tested on five soils. Biochars on all soil types increased soil C. Biochar C was stable in soil with mean residence times estimated in the hundreds of years. Soil nitrate levels were reduced with increasing biochar rate perhaps due to ammonium adsorption. Biochar did not accelerate loss of indigenous organic matter through the 'priming effect.' Biochars raised soil pH, but did not lead to consistent plant growth improvements.

Organic Waste to Resources Research and Pilot Project Report: Converting Washington Lignocellulosic Rich Urban Waste to Ethanol (September 2009) - This study investigated the potential of producing ethanol from three primary sources: mixed waste paper, yard trimmings, and a laboratory prepared mixture (50/50 food & paper) representing MSW. Pretreatment consisted of dilute acid hydrolysis (mixed paper and MSW), and steam explosion (yard waste). Ethanol yields of 105, 90 and 55 gal/ton were found for the MSW, mixed paper, and yard waste. A preliminary Life Cycle Assessment showed that overall environmental impacts of ethanol production from MSW are highly beneficial compared to landfill. Conversion of the MSW mixture to ethanol was found to be economically viable.

It proved that sugars recovered from pyrolysis can be easily converted into ethanol. These two results are important because they show that fast pyrolysis of wood or straw followed by bio-oil hydro-treatment can create green gasoline and diesel (from lignin), as well as ethanol (from cellulose).

The VFA are then fed to yeast for simultaneous carbon sequestration resulting in production of biodiesel from the oil-producing microbial biomass.

Quality standards for ethanol as a fuel are set by the American Society for Testing and Materials (ASTM) International. There are two standards: 1) D4806-04a is the standard specification for denatured fuel ethanol (1 to 10 percent) for blending with leaded gasolines; and 2) D5798-99 (2004) is the standard specification for denatured fuel ethanol (a nominal 75 percent to 85 percent by volume). This and other ethanol standards are available for sale by ASTM International.
Does the energy used to produce ethanol (crop production and refining) exceed the embedded energy in the fuel? Estimating the Net Energy Balance of Corn Ethanol, from the Economic Research Service of U.S. Department of Agriculture (2002) is an updated report that shows there is a net positive energy gain from ethanol production, with a ratio of 1.34 to one (energy out versus energy in). In addition, Argonne National Laboratory has developed a software analytical tool called GREET. GREET stands for Greenhouse Gases, Regulated Emissions and Energy Use in Transportation. Both net energy efficiency and greenhouse gasses are modeled using this tool. It is public domain. The August, 2005 PowerPoint entitled Energy and Greenhouse Gas Emissions Impacts of Fuel Ethanol provides an analytical overview of the net energy of ethanol and plots all the various studies of net energy balance in graphical form.

Gasification and pyrolysis are closely related emerging bioenergy technology options. They are thermochemical in approach as opposed to biological. Fuel, power and chemicals can be made from across the range of these technologies. A number of gasifiers are now online throughout the United States and others are in various stages of project development. Gasification heats organic material and drives off the volatile organic compounds into what is called producer gas. Pyrolysis adds pressure and can produce bio-oils. Various temperatures yields different results. Lower temperatures leave a very stable activated/crystallized carbon or biochar. Biochar is of special interest for two reasons: 1) The potential for carbon negative energy; and 2) The major soil improvements provided by biochar. Higher temperature systems produce more gases and leave an ash.
