Recycling of iron foundry sand and glass waste as raw material for production of whiteware.
The purpose of this study was to evaluate the production feasibility of triaxial whiteware using sand from cast iron moulds as a raw material instead of silica, and recycled glass in place of feldspar. Formulations were prepared using sand, glass waste, and white-firing clay such that only 50% of the composition was virgin material (clay). The ceramic bodies were formed by pressing and fired at...
متن کاملExploitation of Material Property Potentials to Reduce Rare Raw Material Waste A Product State Based Concept for Manufacturing Process Improvement
Manufacturing companies today face fierce global competition and volatile and rising prices on an ever more restricted natural raw material supply market. Customers demand high quality of the purchased products and supplying companies have to find ways to fulfill these customer requirements. In general, there are two ways how companies can meet specific requirements when material properties are...
متن کاملStaphylococcus xylosus fermentation of pork fatty waste: raw material for biodiesel production
The need for cleaner sources of energy has stirred research into utilising alternate fuel sources with favourable emission and sustainability such as biodiesel. However, there are technical constraints that hinder the widespread use of some of the low cost raw materials such as pork fatty wastes. Currently available technology permits the use of lipolytic microorganisms to sustainably produce e...
متن کاملUse of vitrified urban incinerator waste as raw material for production of sintered glass - ceramics
The crystallisation behaviour of vitrified industrial waste (fly ash from domiciliary solid waste incineration) was examined by differential thermal analysis, X-ray diffractometry and scanning electron microscopy. It was demonstrated that powder processing route was required to transform the vitrified industrial waste into glass-ceramics products. Time-Temperature-Transformation (TTT) diagrams ...
متن کاملTurning Waste into By-Product
This paper studies how the conversion of a waste stream into a useful and saleable by-product affects a firm’s optimal operating strategy. We determine whether local implementation can be optimal, i.e., continuing business-as-usual to produce the original product and merely converting the collaterally generated waste stream into by-product, or whether global implementation – that re-optimizes t...
