Hazardous waste pollutes the air, soil, and water and adversely affects human health if not disposed of safely. Analysis of the efficiency of hazardous waste disposal is essential to sustainable development. This paper uses the three-stage super-efficiency Data Envelopment Analysis model to measure the efficiency of 28 EU countries from 2004 to 2016. To ensure the reliability of the results, the article utilizes a one-way ANOVA statistical test to verify whether DEA results vary significantly across various EU countries. This article discusses “how inputs and outputs can be adjusted to eliminate inefficiencies” to suggest a targeted improvement. The third stage supper efficiency DEA results shows that the efficiency varies significantly across different EU countries. The main reasons for the low efficiency are high generated hazardous waste, management expenditure, greenhouse gas emissions, and inadequate waste disposal volume. Targeted proposals from three aspects are given for policymakers in EU countries: Build a resource recycling system to reduce hazardous waste. Establish a sound fee management system to reduce expenses. Optimization of disposal technology to improve incineration efficiency.
