A growing number of companies engage in sustainability, with early adopters already realizing financial and environmental benefits. However, the current linear production model followed by most manufacturers is widely recognized as not being sustainable. The circular economy can be an eco-friendly alternative to consumption, ensuring a smooth transition sustainable practices. In this study, impact various practices manufacturing reviewed well life cycle assessment quantification simple fast methodology for get first indication about potential improvements their lines required changes adopting missing from literature. main objective study provide quantified that facilitates decision-making at process system level regarding adoption more strategies. An eco-efficiency indicator proposed targeting reduction energy consumption waste caused operations, on top cost analysis process. combines process's performance, whose calculation performed using studies, value derived combination costing product-related metrics encapsulated under umbrella overall equipment effectiveness, implementation signifying replacing existing adopt strategy. Additionally, constrained any geographical coverage applies use case long constructed ISO 14044:2006 standard. approach examined two industrial cases, which evaluated against three strategies improved renewable sources, material reuse.

A review of cathode and electrolyte recovery from spent lithium-ion batteries: Recent technologies, processes and policies

Resources Chemicals and Materials, Journal Year: 2024, Volume and Issue: 3(3), P. 188 - 229

Published: Feb. 3, 2024

Recently, lithium-ion batteries (LIBs), due to their superior performance, have been vastly applied in electronic, auto, and other industries, resulting the generation of an increasing amount spent LIBs. What's worse, LIBs contained potentially toxic substances, including heavy metals, flammable electrolyte containing LiBF4, LiClO4, LiPF6. Conventional disposal via landfill or incineration exerts tremendous pressure on environment. It was necessary adopt efficient, low-cost, environmentally friendly approaches valorizing LIBs, which could not only alleviate shortage rare resources by recycling valuable elements such as Cu, Li, Mn, Ni, Co, Al, but also eliminate pollution harmful components realize sustainable industry related consumer electronics electric vehicles (EVs). Given this, this paper summarized technologies pyrometallurgy (melting reduction roasting methods) hydrometallurgy (leaching, precipitation, extraction, ion-exchange, electrochemical, sol-gel methods), (organic solvent extraction supercritical methods). Pyrometallurgy had relatively decent metal recovery rates were associated with high energy consumption atmospheric emission issues. Hydrometallurgical more efficient recovering although disposing wastewater generated from process remained a challenge. In addition, different industrial processes various countries' policies investigated. end, outlooks future directions proposed.
