Current waste management policies favor biogases (digester gases (DGs) and landfill gases (LFGs)) valorization as it becomes a way for energy politics. However, volatile organic silicon compounds (VOSiCs) contained into DGs/LFGs severely damage combustion engines and endanger the conversion into electricity by power plants, resulting in a high purification level requirement. Assessing treatment...

of talk (see introduction to the articles, above): At present, nuclear fission reactors produce a sizeable fraction of the electricity in the developed world: nearly 20% in the US. and substantially greater fractions in many western European countries and in the most developed Asian countries. However. the construction of new nuclear power plants has stopped almost everywhere. with very few ord...

The potential of three submerged aquatic plant species (Cabomba piauhyensis, Egeria densa, and Hydrilla verticillata) to be used for As, Al, and Zn phytoremediation was tested. The plants were exposed for 14 days under hydroponic conditions to mine waste water effluents in order to assess the suitability of the aquatic plants to remediate elevated multi-metals concentrations in mine waste water...

The Strategic Teaming and Resource Sharing (STARS) alliance includes six pressurized water reactor (PWR) stations, all located west of the Mississippi River: Callaway, Comanche Peak, Diablo Canyon, Palo Verde, South Texas Project (STP), and Wolf Creek (Palo Verde joined in 2002). In 2000, a STARS radwaste team was formed to pursue cost reductions. The team was challenged to obtain a 10 percent ...

ith the arrival of the 115th U.S. Congress, the House of Representatives began hearings on the Nuclear Waste Policy Amendments Act of 2017. The legislation restarts Yucca Mountain as a repository for highly radioactive waste. In 1987, Congress amended the Nuclear Waste Policy Act of 1982, selecting Yucca Mountain, Nevada, as the only site to be studied, expecting the repository to open in 1998....

Abstract The possibility of processing ash and slag waste formed during the combustion coal fuel in boiler units thermal power plants into functional geopolymer materials has been studied. world experience various is presented, potential danger described. chemical composition microstructure Apatity CHPP Severodvinsk CHPP-1 were Raw have developed, their synthesis carried out. physico-mechanical...

In this study, the effects of non-hazardous levels of heavy metal (Zn, Cu, Cr and Cd)-enriched organic waste on biomass partitioning and heavy metal accumulation in plant organs in July and October were determined for two poplar clones (Populus deltoides × maximowiczii—clone Eridano and P. × euramericana—clone I-214) commonly used in Italian poplar plantations. Soil amended with the industrial ...

Mercury has long been recognized as a serious global pollutant that has a significant impact upon our ecosystem. Unlike most other pollutants, it is highly mobile, non-biodegradable, and bio-accumulative and as a result has to be closely monitored to ensure its harmful effects on local populations are minimized. Approximately 50 tons of mercury particulates are emitted into the atmosphere every...

An excel-based model was developed to evaluate economic and environmental benefits of the solar-powered compaction garbage bins in public areas in Australia. Input data were collected from Brisbane and Wollongong City councils, and Sydney Olympic Park. The results demonstrate that solar-powered compaction garbage bins would provide environmental benefits in all scenarios. However, results of th...
