In twenty-first century, the world has become dependent and addicted to electronic gadgets like mobile phones, laptops, tablets, etc. The increased use of gadgets has led to a huge generation of E-waste (Electrical and electronic waste). Therefore, management of E-waste has become a major concern at the global level. Life cycle assessment (LCA) evaluates and quantifies the environmental impact of an electronic product from its rawmaterial till its disposal. The techno-economic analysis (TEA) recognizes the technical modifications to overwhelm existing obstacles in commercial E-waste recycling units. The present chapter deals with the LCA and techno-economic analysis of E-waste recycling. This “Lifecycle Evaluation” (combination of LCA and TEA) would help in understanding the environmental and social impacts, which would facilitate the E-waste recycling processes. This approach would prove to be an important tool in developing E-waste management schemes in a sustainable way. © 2024 by John Wiley & Sons Inc All rights reserved.
