ABSTRACTThis article aims to list the main sustainable practices developed in the processes of metal forming, casting, heat treatment, welding and electrostatic painting. When analysed the literature about sustainable manufacturing, a predominance of studies about machining is observed and the processes mentioned are few explored in academic studies. The research strategy used to reach the objective was systematic literature review, conducted for each process cited. Many sustainable practices were identified with prominence of better materials use and energy efficiency. The authors of this article believe that the information presented here can be useful for researches in their future studies and for industry professionals interested in improving manufacturing processes. 相似文献

Biodegradable films were produced by extrusion from blends of starch, glycerol and poly(butylene adipate co-terephthalate), a biodegradable polyester, with the addition of 1.5 % (wt/wt) saturated fatty acids (caproic, lauric or stearic). Films containing fatty acids had higher crystallinity than control films and the longer the carbon chain of the acid was, the more crystalline the film. Fatty acids with up to 12 carbon atoms did not alter the viscoelastic characteristic of the films. Further, the incorporation of fatty acids did not decrease the hydrophilicity of the films in comparison with the control film without a fatty acid. 相似文献
