Using the LCA Method to Develop the Production of Pigment for Processing Plastics

Area of Science:

• Environmental Science
• Materials Science
• Chemical Engineering

Background:

• The dynamic chemical industry introduces new substances, some with potential toxicity to humans and ecosystems.
• Polymer materials, widely used across industries, face scrutiny regarding the environmental and health impacts of their processing, particularly concerning colorants.
• A need exists for robust methodologies to quantify the ecological and health effects of colorants in plastic processing.

Purpose of the Study:

• To quantitatively and qualitatively determine the impact of coloring agents in plastic processing on human health and the environment.
• To identify specific technological operations and materials with the highest negative environmental and health footprints.
• To evaluate the potential benefits of recycling processes in mitigating these impacts.

Main Methods:

• Utilized the Life Cycle Assessment (LCA) methodology.
• Employed the ReCiPe 2016 impact assessment method for analysis.
• Analyzed various technological operations and polymer materials involved in plastic processing and coloring.

Main Results:

• The heating process during material treatment exhibited the most significant negative environmental impact (2.08 × 10^-1 Pt).
• Polyethylene terephthalate demonstrated the most substantial adverse effects on human health (2.91 × 10^-1 Pt) and environmental quality (2.35 × 10^-2 Pt).

Conclusions:

• Implementing recycling processes offers substantial reductions in negative impacts across human health (approx. -3.71 Pt), ecosystems (approx. -0.14 Pt), and resource depletion (approx. -0.27 Pt).
• The study highlights the critical need for sustainable practices in the chemical and polymer industries, emphasizing the role of LCA in identifying and mitigating environmental hotspots.
