Characterizing the Municipal Solid Waste Stream in Denton, Texas
… dumpsters from Denton's Municipal Solid Waste Stream were emptied, sorted and weighed to characterize the material types and make preliminary recycling policy recommendations. The general composition of Denton's solid waste stream was not significantly different from the composition of …

Waste-Stream Management Optimization in Long-Duration Crewed Space Missions
… have adopted rudimentary strategies to manage waste-streams generated inside spacecraft. Currently, on the International Space Station (ISS), waste-streams are stowed for months and later loaded onto an outbound cargo vehicle for incineration in the Earth's atmosphere. But as humans start to …

Decontamination and Valorisation of a Corn-to-Ethanol Biofuel Waste Stream
… resulting in the generation of novel, complex waste streams which challenge conventional treatment methods. This study investigates the physiochemical characteristics, decontamination and valorisation potential of a tertiary waste stream (TWS) produced during a corn-to-ethanol whole stillage …

Development of an innovative and environmentally sustainable solid waste stream treatment process.
Oily sludges and oil contaminated solid wastes are generated from various sources such as from a) interceptors in petrol stations, automobile garages and rail service stations b) tank oil bottoms from crude oil storage tanks c) drill cuttings from oil and gas exploration and d) Oil based drilling …

Waste Less District: An Exploration of Architecture's Role in the Waste Stream
… It is well documented that the majority of human waste ends up in on the side of roads, or in forests and oceans if not in landfills or incinerated. The disposability of items in our consumer culture is now commonplace. We are exacerbating our problems by throwing away single-use and barely-used …

Treatment of the caustic extraction waste stream of a sulfate pulp process
… amount of color V from the caustic extraction waste of a sulfate pulp process. After a thorough search of the related literature was completed, experimental tests were conducted using activated carbon and aluminum sulfate. Fourteen tests employing activated carbon were made at 25 °C, pH values …

Meeting state waste stream reduction mandates through recycling: examining residential waste disposal behavior in rural Virginia
Solid waste management has become an increasingly costly issue for localities throughout Virginia. The Commonwealth has established a state-mandated recycling rate of 25 percent to be achieved by July 31, 1995. The mandate, however, may not adequately consider the diversity of individual localities …

Increasing proliferation resistance of sodium fast reactor fuel cycle through use of a nuclear resonance fluorescence detector
… plant. In an aqueous reprocessing facility, the waste stream was identified as a weak point for proliferation resistance. By identifying the isotopic composition of the waste stream and monitoring levels of plutonium and uranium, greater accountancy can be maintained. After the detection system …

Waste-Based Economic Development in Springfield, Missouri
With the growing public interest in solid waste management, the question arises of what communities are to do with their accumulated solid waste. The hypothesis of this study is that recovering resources from the municipal solid waste stream and attracting and developing industries that can reuse …

Biological treatment of waste solutions generated from the remediation of perchlorate-contaminated waters
… However, regeneration of these resins creates a waste stream, concentrating the perchlorate and other components in the regenerant solution. This waste stream can then be channeled to a biological reactor where perchlorate is reduced by microorganisms. Perchlorate-reducing microorganisms are …

Recovering Requeche and Classifying Clasificadores: An Ethnography of Hygienic Enclosure and Montevideo’s Waste Commons
… as experienced through the lives and labour of waste-pickers around Uruguay’s largest landfill, Felipe Cardoso. These workers are known as clasificadores [classifiers] in recognition of their role separating whatever can be recovered from the waste stream from that which cannot. Conducted from a …

City of Denton Municipal Solid Waste Characterization and Management Strategies
… the City of Denton contracted a municipal solid waste characterization study in 1999 that would identify materials for diversion. This paper describes the results of 5 1-week waste sorting events, a scale-house analysis, a recycling participation study, a recycler profile and a similar city …

Enzyme diffusion and cellulose breakdown in the bioremediation of medical waste
The disposal of infectious medical waste has become a major environmental concern. New disposal methods are currently being investigated; one of these is a bioremediation process which utilizes enzymes in a batch reactor to render the waste noninfectious. The success of this biological process …

Physicochemical and biological treatability study of textile dye wastewater
The textile industry discharges a highly colored wastewater characterized by high organic levels. Industrial wastewater with these characteristics can be harmful to receiving streams and municipal plants, and must be treated prior to discharge. In this project, a yam dyeing facility was studied …
