Fusion devices appear to be a viable option for burning their own high-level waste (HLW). We propose a novel waste management strategy to eliminate (or minimize) the HLW generated by fusion systems. The main source of the fusion HLW includes the structural materials without impurity control, recycled materials, refractory metals, and liquid breeder cleanup and reprocessing systems. The basic id...

Abstract--Textile dying industry effluents are highly toxic in nature and it contains a large number of complex metal dyes. Many dyes used in textile industries are stable to light and resistant to aerobic digestion. Thus removal of coloured waste from industrial dye effluent is a most perplexing problem to such industries and the environment. On the other hand fly ash is a major pollutant gene...

Fuel cycle cost of a fast reactor is expected to play an important role of compensating for higher capital cost of a Fast Reactor and keeping the unit energy cost competitive. PFBR fuel cycle cost has been worked out by a committee constituted for the purpose. The cost has been worked out for a peak fuel burn-up of 1,00,000 MWd/t. The basic components of the PFBR fuel cycle are fabrication cost...

The effects of food waste vermicompost on populations of adult striped cucumber beetles (Acalymma vittatum) and spotted cucumber beetles (Diabotrica undecimpunctata) on cucumbers and larval hornworms on tomatoes (Manduca quinquemaculata) were evaluated in both greenhouse and field experiments as well as damage caused. In the field, cucumber and tomato plants were grown, with two different appli...

Plants initially accepted by foraging leaf-cutting ants are later avoided if they prove unsuitable for their symbiotic fungus. Plant avoidance is mediated by the waste produced in the fungus garden soon after the incorporation of the unsuitable leaves, as foragers can learn plant odors and cues from the damaged fungus that are both present in the recently produced waste particles. We asked whet...

Waste is omnipresent in construction supply chains. It often occurs at the interface between processes, disciplines, or organizations. To illustrate several causes of waste, this paper focuses on a case study that documents the most common configuration of the supply chain for pipe supports used in the power plant industry. Using value-stream mapping across organizational boundaries, this paper...

samples of the waste rock obtained from marofengin south africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. the results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, 70 a...

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...

There is a considerable interest in low activation and high heat resistant materials for fusion applications. Tungsten (W) would fulfill these requirements for plasma facing components of future fusion power plants. A novel method developed by SNL to enhance the thermal and dimensional stability of W requires depositing materials such as Re and Mo as a thin coating on the surface of dendritic W...
