  Citation × Citation Citation Abstract Copy Title: Tillamook County Waste Disposal Technology Assessment Author: Kumar, Arvind, Menze, Ryan, Smith, Joe, Thomas, Jerrod Year: 2014 Tillamook County is a rural county straddling the Northern Oregon Coast Range with the majority of the local economy based around agriculture, timber, tourism, and fishing. As part of Tillamook County’s mission statement, they strive“to enhance the quality of life for its citizens by promoting and preserving public health and safety, maintaining a stable economy, encouraging wise use of resources, and providing services in the most efficient and cost-effective manner possible.” To that end, Tillamook County, Tillamook County Economic Development Council (TCEDC), Portland State University, Oregon State University, and Tetra Tech have undergone an evaluation and technology assessment process to determine a sustainable, economically-viable, and socially-acceptable pilot installation capable of dealing with the large amount of biodegradable waste produced by the timber and dairy industries. This survey provides a technology assessment and recommendations regarding three potential technologies: thermophilic composting, gasification/pyrolysis, and direct incineration. Each of these technologies have strengths and weaknesses in dealing with the three waste streams (manure, bovine carcasses, and timber slash), and this analysis works as a decision-making guide for choosing the proper technology or array of technologies to dispose of Tillamook County’s biodegradable waste.

  Citation × Citation Citation Abstract Copy Title: Technology Assessment of Waste Disposal Technologies for Tillamook County Author: Jain, Abhishek, Lui, Jonathan, Jiang, Jing, Garcia, Jorge, Limarta, Standley Year: 2014 In the paper, a two-level filter system is proposed to evaluate the potential for alternative waste management practices by conversion of locally-generated waste products such as animal mortality, manure, and wood waste into beneficial products such as energy in Tillamook county of Oregon. At the first level – coarse grained filter, three basic factors, technical readiness level (TRL), scaling capacity, and feedstock, are used to initially filter out the scanned technologies which can be potentially used in waste management. At the secondary level filter – fine grained filter, a numeric scoring model is created to evaluate technologies from the output of the first level filter. Since many factors will impact the selection of a technology, HDM (Hierarchical decision model) is used to score technologies. From technical, economic, social, and environmental perspectives, hierarchical multi-criteria factor structure is created, and constant-sum and pair-wise comparison are used to subjectively create the priority probability list about technologies. Composting technology, rendering technology, and hydrolysis are analyzed in detail. This developed alternative strategy will help to mitigate local liabilities, promote green jobs, develop clean energy, and reduce the carbon footprint in Tillamook County.
