Sustainable considerations in additive manufacturing processes: A review
Efficient waste management practices are becoming increasingly necessary due to the negative environmental and health impacts of waste generation and disposal. One type of waste that has received particular attention is electronic waste (e-waste). This category of waste has the potential to cause significant environmental harm if not disposed of properly. The management of e-waste is crucial in the electrical/electronic industry which has led to the creation of models and institutional legislature to promote sustainable production processes. Among these processes, Additive manufacturing otherwise referred to as 3D printing is particularly effective in reducing waste generation and energy requirements by reusing spent parts and products as feedstock. Sustainability in the manufacturing and production sectors can be promoted through the inculcation of certain practices. Of these practices, reusing e-waste that would otherwise be disposed of in landfills has the potential to promote environmental cost savings. This article introduces the potential of e-waste being integrated into the manufacturing sector to promote sustainable production. The article also addresses the problem of geometric e-waste generation and suggests an efficient way of reusing waste from the electrical and electronic industries.
期刊介绍:
The Journal of Mechanical Engineering & Sciences "JMES" (ISSN (Print): 2289-4659; e-ISSN: 2231-8380) is an open access peer-review journal (Indexed by Emerging Source Citation Index (ESCI), WOS; SCOPUS Index (Elsevier); EBSCOhost; Index Copernicus; Ulrichsweb, DOAJ, Google Scholar) which publishes original and review articles that advance the understanding of both the fundamentals of engineering science and its application to the solution of challenges and problems in mechanical engineering systems, machines and components. It is particularly concerned with the demonstration of engineering science solutions to specific industrial problems. Original contributions providing insight into the use of analytical, computational modeling, structural mechanics, metal forming, behavior and application of advanced materials, impact mechanics, strain localization and other effects of nonlinearity, fluid mechanics, robotics, tribology, thermodynamics, and materials processing generally from the core of the journal contents are encouraged. Only original, innovative and novel papers will be considered for publication in the JMES. The authors are required to confirm that their paper has not been submitted to any other journal in English or any other language. The JMES welcome contributions from all who wishes to report on new developments and latest findings in mechanical engineering.
