Material life cycle assessment for diecasting process
The main emphasis of this study is to evaluate the potential environmental impact of diecasting process, which is one of well organized and kind of green technologies in casting processes. Material life cycle assessment (MLCA) was carried out in actual diecasting factory that produces various lightweight aluminum and magnesium components to obtain life cycle inventory data, quantify environmental impacts and finally try to get solutions for environmental improvement. In diecasting process, most of environmental impacts come from melting of raw materials for abiotic resource depletion and global warming due to burning gas and electricity used. The problem of photochemical oxidant creation is induced by spraying and lubricating steps.
