Analyzing the environmental performance of epoxy compositions for cryogenic use: A comparative LCA study

Area of Science:

• Materials Science
• Environmental Science
• Chemical Engineering

Background:

• Composite materials, particularly glass fiber-reinforced polymers with epoxy matrices, are widely used but pose environmental challenges.
• Increasing demand for sustainable engineering materials necessitates precise environmental parameter declarations.
• Limited comprehensive environmental analyses exist for novel composite materials.

Purpose of the Study:

• To analyze the environmental impact of newly developed resin compositions for cryogenic applications.
• To compare the carbon footprint and life cycle impact of Resin A and Resin B.
• To provide novel environmental data for composite material production in Poland.

Main Methods:

• Calculation of carbon footprint (CF) emissions for both resin compositions.
• Application of Recipe 2016 Midpoint (H) Life Cycle Impact Assessment (LCIA) methodologies.
• Comparison of environmental impacts across categories including global warming, toxicity, water consumption, and ecotoxicity.

Main Results:

• Composites using Resin A exhibited a lower carbon footprint than those using Resin B.
• Resin B production showed significant adverse impacts in global warming, human toxicity, water consumption, and marine aquatic ecotoxicity.
• Resin B had higher environmental burdens in chemical ingredients (22.34%), electricity (23.36%), and heat (89.11%) compared to Resin A.

Conclusions:

• Resin B has a demonstrably detrimental impact on the environment compared to Resin A.
• The findings highlight the need for environmentally conscious resin selection in composite material manufacturing.
• This research provides valuable, company-specific environmental data for composite materials in Poland.
