An Integrated Organic Waste Management System:  From the Perspective of Commercial Waste Generators, 2010
This report analyzes anaerobic digestion as a new organic waste management concept from the perspective of commercial waste generators located in Ramsey and Washington counties by exploring logistics of daily operations, types of upfront costs, and changes in the configuration of waste management services. 

Organic Materials from Commercial Establishments:  A Supply Assessment, 2010
The assessment contains preliminary estimates of quantities of commercial organic materials not currently recovered by other programs that may be available as feedstock for an anaerobic digestion (AD) facility.  It also characterizes the types of commercial establishments that may be sources of targeted organic materials such as food scraps and non-recyclable paper.

Source Separated Organic Materials Anaerobic Digestion Feasibility Study, 2009
This study examines the feasibility of an anaerobic digestion (AD) facility for source separated organic materials (SSOM) collected from eight counties in the Twin Cities metropolitan area.  The feasibility study examines current AD technologies, availability of SSOM, and utilizing AD technology to convert the organic material to methane for thermal or electric power generation.

Carbon Emission Analysis to Transport Recyclable Paper, 2008
The purpose of this study was to analyze the impact on greenhouse gas (GHG) emissions if the Rock-Tenn facility in St. Paul, Minnesota no longer operated as a paper mill causing the 1,000 TPD of paper currently processed at their facility to be transported to other locations for processing.  This study quantifies the change in GHG emissions produced from transporting this material to Rock-Tenn for processing to the GHG emissions produced from transporting this material to alternative locations.

Research Study Gasification, Plasma, Ethanol, & Anaerobic Digestion Waste Processing Technologies, 2008
The following report details the alternative waste processing technologies for municipal solid waste.  The technologies reviewed include gasification, plasma arc, ethanol production and anaerobic digestion.  Each of the technologies is discussed as to the process, products recovered and potential uses, environmental concerns, regulatory issues, and experience with the technology.

Renewing Rock-Tenn: Biomass Fuels Assessment, 2007  by The Green Institute

Updated Research Report on Bioreactor Landfills, Landfill Leachate Recirculation and Landfills with Methane Recovery, 2004
The report reviews the status of three technologies:  resource recovery, leachate recirculation and methane recovery.  The report describes each technology, how it may apply to Ramsey and Washington counties, and potential advantages and disadvantages.  While leachate recirculation and methane recovery are addressed separately, it is important to note that leachate these technologies are both part of the bioreactor landfill technology.  

Updated Research Study of Alternative Waste Processing Technologies, 2004
This report updates information on the following technologies:  Mass Burn Waste-To-Energy, Dedicated RDF Combustion Facility, Mixed Waste Processing (Front-end Separation), Thermo-chemical Processes, and Ethanol Production Anaerobic Digestion.  A brief description of each technology, its perceived advantages and disadvantages, and observations on its applicability to Ramsey/Washington (R/W) counties is included in the report. 

Public Collection Analysis, 2002
In 2001 the Ramsey and Washington Boards of County Commissioners passed resolutions directing the Ramsey/Washington County Resource Recovery Project to study a public solid waste collection system.  This report provides in-depth reporting on: the problem; evaluation of similar programs; efforts to gauge the neighborhood, business and city government responses to a changed solid waste collection system; analysis of potential options; and staff recommendations.

Comparison of Potential Electricity Production from RDF and LFG, 2001
This analysis compares the potential electricity production from Municipal Solid Waste (MSW) using either Refuse Derived Fuel (RDF) technology or Landfill Gas (LFG) technology.

Research Study of Alternative Waste Processing Technologies, 2000
This report covers background information related to the Ramsey/Washington Counties waste stream and descriptions of six alternative processing technologies.

Research Feasibility of Dedicated Combustion Facility, 2000
This report covers some preliminary costs, permitting requirements, and issues related to electric utility deregulation.
