Taking Trash Out of Hiding
Out of sight, out of mind has been the country's solid waste mind-set. But when the $18 million Phoenix Solid Waste Management Center becomes fully operational in April, visitors...
Shear Design Guidelines for Polyester Concrete Using Recycled Plastic
Previous research on the shear behavior of steel-reinforced polymer concrete (PC) beams has been very limited and no efficient design procedures have been proposed. In all the previous...
Special Considerations in the Design of Connections for Recycled Wood/Plastic Composite Lumber
There is current work in the American Society for Testing and Materials (ASTM) to evaluate potential test methods for what they refer to as 'commingled' plastic lumber. This category covers...
Recycling Portland Cement Concrete Pavement at the Contractor's Option
This paper summarizes three portland cement concrete airfield pavement recycling projects at the Outagamie County Airport in Appleton, Wisconsin. The specifications for the projects did...
Water Reclamation Potential in Southern California to the Year 2010
This is a summary of plans and projections for future water recycling by Southern California public and private water and sewerage agencies involved in water recycling. The central purpose...
Reusable Water Exhange Modeling
Wastewater return flows of raw water which is reusable, i.e., water which is entirely consumable, can be exchanged for a like amount of water upstream in the river basin. Exchanged water...
Decision-Making Paradigm for Risk Assessment of Hazardous Wastes Using Fuzzy Sets
This paper summarizes the development of a risk assessment framework to provide risk-cost policy alternatives to prioritize remediation actions for hazardous wastes. The framework is a...
Risk-Based Management of Uncertainty During Project Planning and Execution
The Land Disposal Restrictions (LDRs) of the Resource Conservation and Recovery Act (RCRA) are the critical technical standards for the establishment of compliance plans and schedules...
Waste Minimization and Recycling by Microfiltration during Nitrocellulose Manufacturing
A plant survey was conducted to determine the amount of nitrocellulose (NC) discharged with process water from each of five sequential NC purification processes. Wastewater samples were...
Beneficial Use of Ash: An Innovative Approach to Sludge Management
Disposal of ash resulting from the incineration of municipal sewage sludge has historically been a relatively easy, albeit, expensive requirement. The traditional method of disposal is...
Modifying One of the Nation's Most Successful Biosolids Lime Stabilization Operations
Since 1978, the Vallejo, California, Sanitation and Flood Control District has managed a tremendously successful biosolids program consisting of lime stabilization and agricultural land...
Recovery and Recycling of Copper from Wastewater using Iron Coated GAC
The purpose of this study was to prepare composite adsorbents that could be packed into a column and have adsorption characteristics similar to Fe oxide. This adsorbent was targeted to...
Denitrification Inhibition by High Nitrate Wastes
The adaptation of activated sludge and inhibition of denitrification at high nitrate concentrations was studied using pH controlled bench-scale sequencing batch reactors (SBRs), operated...

Current Plans to Characterize the Design Basis Ground Motion at the Yucca Mountain, Nevada Site
A site at Yucca Mountain Nevada is currently being studied to assess its suitability as a potential host site for the nation's first commercial high level waste repository. The DOE has...
Geotechnical Instrumentation for Repository Shafts
The United States Congress passed the Nuclear Waste Policy Act in 1980, which required that three distinctly different geologic media be investigated as potential candidate sites for the...
Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...
Development of the Planning and Control Segment, CRWMS Transportation System
This paper discusses the current plans for the development of the Planning and Control segment of the SRWMS Transportation System. Each of the four Planning and Control subsystems are...
Congressional-Executive Interaction and the Nuclear Waste Repository Site Selection Process
The Nuclear Waste Policy Act of 1982 (NWPA) (P.L. 97-425) and the Nuclear Waste Policy Amendments Act of 1987 (NWPAA) (Title V of P.L. 100-203) provide the framework for the Department...
