Abstract
This study aims to analysis the environmental impact on waste catalyst recycling technology using entire life cycle assessment. Environmental impacts consist of the five categories of impacts: global warming, resource depletion, acidification, eutrophication, and photochemical oxide production. The waste catalyst recycling presently have a GWP 3.53 ton $CO_2$ equivalent/ton, a ADP 0.017 ton Sb equivalent/ton, a AP 0.051 $SO_2$ equivalent/ton, a EP 0.0092 $PO{_4}^{3-}$ equivalent/ton, a 0.0019 ton $C_2H_4$ equivalent/ton. The smelting reduction process is the greatest contributor to all categories of environmental impacts in waste catalyst recycling. Electricity used in the smelting reduction process is the major contributor of all impact categories.
