Environmental Impact Assessment of Different Strategies for the Remanufacturing of User Electronics

Over the years, innovation and development of electrical electronic equipment have been on a steep rise. Millions electronics are being sold or discarded every year in form waste. Sustainable IT (Green Circular Computing) is one most environment-friendly methods reusing waste user electronics. The remanufacturing computer refers to disassembly, repair, upgrade original give it new life, along with warranty that as good product. goal this work includes studying assessing total environmental impact refurbishing using life cycle assessment (LCA) integrated discrete event simulation (DES), compare two business models: (1) case centralized where plants Middle East, which hub for receiving distributing remanufactured goods; (2) decentralized situated each continent over range models. was conducted openLCA software combination WITNESS Horizon DES. results show much more environmentally friendly option computers, operation has better throughput well efficiency, compared operation. scenario climate change 1035.19 kg CO2-Eq, an 816.12 CO2-Eq. In terms marine found 0.28 N-Eq impact, (0.22 N-Eq). However, does not us complete picture, its previous remains unknown. Multi process can be used get clearer picture ecological footprint during multiple cycles.
