Abstract:
Introduction: This research paper explores the environmental sustainability of
ionic liquid-based green solvents in the extraction and purification of natural plant products,
with a focus on their entire life cycle. The objectives of the study were to assess the
environmental impact of ionic liquid synthesis, energy consumption, water usage, emissions,
recycling rates, policy effects, and stakeholder perceptions.
Methods: Methodologically, we conducted a comprehensive Life Cycle Assessment
(LCA) that involved primary data collection through field surveys and interviews with
key stakeholders in the ionic liquid production and usage industry across various regions
in India. The data were analyzed using specialized LCA software tools to quantify environmental
impacts. Key findings include the identification of synthesis as a major contributor
to environmental impact, emphasizing the need for greener synthesis methods.
Results: The study revealed the significant carbon footprint, energy consumption, and
water usage during production, highlighting opportunities for improvement. Emissions
data underscored the importance of emission control measures, particularly for greenhouse
gases and volatile organic compounds. Recycling and reuse were identified as environmentally
friendly disposal methods. Policy compliance varied among stakeholders,
indicating room for stricter regulations. Stakeholder perceptions varied, with researchers
having the most positive outlook. Implications of the findings extend to sustainable
chemistry practices, emphasizing interdisciplinary collaboration and the importance of
considering the entire life cycle of chemical processes.
Conclusion: This research contributes to a deeper understanding of green solvents and
provides a foundation for promoting sustainable practices in industrial processes in India
and globally.
