“…Studies [29,31] indicated that the cold compaction process did not result in metallic bonding between particles. In the deformation step, extrusion of pre-compacted scrap at approximately 450-550 °C is performed to obtain good diffusion bonding between particles [32]. It should be noted that new development of severe plastic deformation (SPD), such as high ratio extrusion, equal channel angular pressing (ECAP) may provide new approaches for solid state recycling of automotive aluminum scrap.…”

With the global warming being of concern, the secondary aluminum stream is becoming an even more important component of aluminum production and is attractive because of its economic and environmental benefits. In the paper, recycling of automotive aluminum is reviewed to highlight environmental benefits of aluminum recycling, use of aluminum alloys in automotive applications, automotive recycling process, and new technologies in aluminum scrap process. Literature survey shows that new developed techniques such as Laser Induced Breakdown Spectroscopy (LIBS) and solid state recycling provide promising alternatives in aluminum scrap process. Compared with conventional remelting and subsequent refinement, solid state recycling utilizing compression and extrusion at room or moderate temperature can result in significant energy savings and higher metal yield.

“…These state-of-the-art techniques are critically appraised to understand their potentiality for the current organization [36][37][38][39][40][41]. Solid waste generation level, being the most important CECMI and significant environmental problem, may be taken care of by remanufacturing or recycling.…”

-In recent years, environmentally conscious manufacturing (ECM) has become an important aspect and proactive approach for majority of the manufacturing organizations in India. The reason is that ECM not only helps to produce environment friendly, but also helps to make money by reducing cost or achieving competitive advantage. Industrial gearbox manufacturing organizations have significant environmental impacts as industrial gearbox manufacturing involves several steps which use valuable resources and pollute the environment. Hence, this paper presents an explorative environmental study of an Indian industrial gearbox manufacturing organization. The objective of the current paper is (i) to identify the environmental problems and environmentally conscious manufacturing indicators (ECMI), (ii) to find out the root causes of these problems and (iii) to solve the root causes based on the available stateof-the-art literature. This research work not only reviews the efficient environment friendly manufacturing techniques, but also helps the organization to become eco-efficient by producing environment friendly while making money. First ECMIs selected from literature review, are validated through process mapping. Then these indicators are prioritized using analytic hierarchy process (AHP) to find out the critical environmentally conscious manufacturing indicators (CECMI). The sources of CECMIs are identified using either data envelopment analysis (DEA) or direct observation of the available database. Finally, some possible solutions are also addressed in this paper.

“…The SWOT-type analysis also reveals the different approaches that are considered for inclusion in the development of such a new model. The literature reviewed here relates to the current theoretical modelling of recycling in the fields of "designing for recycling" and "life-cycle costing" [3,8,9,22].…”

In this article the principles of industrial engineering are applied to maximize the profitability of the recycling industry. A case in the plastic recycling industry is presented to demonstrate the practical application of the financial calculation functions developed in the paper. In particular, the profitability maximization concept for the plastic recycling industry was examined, based on the theory of demand and supply. By estimating the profit realizable on regular as well as high product demand, part of the objective of the paper was achieved. Inventory principles were further applied to determine optimum inventory levels. OPSOMMINGDie beginsels van bedryfsingenieurswese word in die artikel toegepas om die maksimisering van winsgewendheid by herwinbaarheidsvraagstukke te bewerkstellig. 'n Voorbeeld wat voorkom by die herwinbaarheid van plastiek word voorgehou om te toon hoedat finansiële modellering aangewend kan word. Voorraadhouding onder toestande van stabiele en toenemende vraag word behandel en in besonderheid ondersoek.
