Abstract

This study introduces the Green Environmental Assessment and Rating for Solvents (GEARS) as a novel metric designed to evaluate the environmental, functional and economic viability of solvents used in research and industrial applications. GEARS integrates comprehensive Environmental Health and Safety (EHS) criteria with Life Cycle Assessment (LCA) to provide a holistic evaluation of solvent efficiency. The metric assesses ten critical parameters: toxicity, biodegradability, renewability, volatility, thermal stability, flammability, environmental impact, efficiency, recyclability, and cost. Each parameter is scored based on specific thresholds, contributing to an overall score that highlights the strengths and weaknesses of each solvent. The effectiveness of GEARS is demonstrated through case studies evaluating methanol, ethanol, acetonitrile, benzene, and glycerol, revealing insights into their overall performance. The results highlight the importance of using a comprehensive assessment tool to facilitate the selection of greener solvents, thereby promoting sustainable practices in the chemical industry. The GEARS software is available as an open-source tool at bit.ly/GEARS2025.

绿色环境评估和溶剂评级（GEARS）作为溶剂选择的创新工具

本研究介绍了溶剂的绿色环境评估和评级（GEARS）作为一种新的度量，旨在评估研究和工业应用中使用的溶剂的环境，功能和经济可行性。GEARS将全面的环境健康和安全（EHS）标准与生命周期评估（LCA）相结合，提供对溶剂效率的全面评估。该指标评估了十个关键参数：毒性、可生物降解性、可再生性、挥发性、热稳定性、可燃性、环境影响、效率、可回收性和成本。每个参数都基于特定的阈值进行评分，从而得出一个总体分数，突出了每种溶剂的优点和缺点。通过评估甲醇、乙醇、乙腈、苯和甘油的案例研究，展示了GEARS的有效性，揭示了它们的整体性能。研究结果强调了使用综合评估工具来促进绿色溶剂选择的重要性，从而促进化学工业的可持续实践。GEARS软件作为开源工具可在bit.ly/GEARS2025上获得。

期刊介绍： Sustainable Chemistry and Pharmacy publishes research that is related to chemistry, pharmacy and sustainability science in a forward oriented manner. It provides a unique forum for the publication of innovative research on the intersection and overlap of chemistry and pharmacy on the one hand and sustainability on the other hand. This includes contributions related to increasing sustainability of chemistry and pharmaceutical science and industries itself as well as their products in relation to the contribution of these to sustainability itself. As an interdisciplinary and transdisciplinary journal it addresses all sustainability related issues along the life cycle of chemical and pharmaceutical products form resource related topics until the end of life of products. This includes not only natural science based approaches and issues but also from humanities, social science and economics as far as they are dealing with sustainability related to chemistry and pharmacy. Sustainable Chemistry and Pharmacy aims at bridging between disciplines as well as developing and developed countries.
