Abstract Secondary aluminum production is required for the conservation of environment. It can significantly reduce greenhouse gas emissions and energy consumption alumina, a source primary aluminum. requires sorting processes metal scrap before starting refining process. Salt slags generated from both secondary need to be recycled/treated as they are considered hazardous byproducts. This revie...

Solid-state recycling, which involves the direct recycling of scrap metal into bulk material using severe plastic deformation, has emerged as a potential alternative to the conventional remelting and recycling techniques. Hot press forging has been identified as a sustainable direct recycling technique that has fewer steps and maintains excellent material performance. An experimental investigat...

India has entered in the field of spent fuel reprocessing as early as sixties by way of R&D studies and finalising the process flow sheet. India's first spent fuel reprocessing plant was commissioned in the year 1965 at Trombay to reprocess spent fuel arising from research reactors. The recovered plutonium is being utilised to feed various programmes of the department. With the passage of time,...

Solid waste management is one of the major environmental concern in the United States. Over 5 billion tons of non-hazardous solid waste materials are generated in US each year. Out of which more than 273 million scrap tires (approximately 3.6 million tons) are generated each year. In addition to this, about 3 billion tires are stockpiled. Several studies have been carried out to reuse scrap tir...

The exclusion of inherent process variations in the current deterministic design methods for sheet metal forming can lead to very unreliable result that may cause high scrap rate, frequent rework, machine shut down and thus huge loss of profit. In this paper, a general approach is presented to quantify the uncertainties and to incorporate them into RSM model so as to conduct probabilistic based...

lexible production: this key strategic goal of every modern manufacturing company has made robotic tending of press brake machines a common sight in sheet metal fabrication workshops. And with advantages over manual tending like better quality, higher efficiency, improved safety, less scrap and accurate repeatability, its popularity is certain to grow. One limitation is slowing its advance, how...

The thermal reprocessing hypothesis in active galactic nuclei (AGN), where extreme ultraviolet/X-ray photons are reprocessed by the accretion disc into optical/UV photons, predicts wavelength-dependent time-delays between the optical continuum at different wavelengths. Recent photometric monitoring by Sergeev et al. has shown that the time-delay is observed in 14 AGN, and generally seen to incr...
