Plastics claim less environmental impact than alternatives
In a new report published by US-based Plastics Industry Association (PLASTICS), plastics are deemed to be more sustainable than alternative materials when life cycle assessments are taken into consideration.
The report, authored by environmental scientist Kenneth Green and titled Plastics and Sustainability, further finds that eliminating plastics would be detrimental to ongoing sustainability efforts and that enhancing recycling systems is a practical solution.
Plastics and Sustainability examined numerous life cycle assessments to determine differences in methodologies measuring the sustainability of different materials, including steel, aluminum, glass, and others. The report acknowledges that plastics’ sustainability can and should continue to improve over time.
“Assessing sustainability has to include plastic’s impacts on the physical environment as well as the climate, including the production of plastics from fossil fuels, and disposal of plastic waste into the environment. But we must take care in choosing alternatives,” said author Kenneth Green. “Comparison studies and common sense tell us that alternative materials will also produce environmental impacts, quite possibly worse than the plastics they replace.”
Plastics and Sustainability is consistent with reports that have looked at compilations of scientific life cycle assessments. One such study from University of Michigan’s School for Environment and Sustainability, published in 2020, found that plastic has fewer environmental impacts than single-use glass, indicating that the increasing trend to substitute single-use plastic packaging with single-use glass-based packaging is “particularly troublesome” from a sustainability perspective.
Key Findings
- Current recycling systems are economically inefficient. However, a full reclamation of plastic monomers would bring society’s use of plastic materials closer to current conceptions of environmental sustainability.
- Contrary to established wisdom, scientific life cycle assessments of plastics and alternative materials find that plastics tend to have lower carbon footprints, making them the more sustainable option among current materials in a number of applications.
- Those life cycle assessments also suggest that substituting plastics with other materials would create environmental tradeoffs that could be less environmentally sustainable.
- Plastics, a relatively novel material in the history of human goods manufacture, have become critical to sustaining prosperous and technological societies. Suggestions to discontinue using plastic would very likely be detrimental to both human and environmental well-being.
