Life Cycle Assessments have shown that plastics have the best environmental advantages compared to other materials
What are Life Cycle Assessments?
Life Cycle Assessments are scientific tools that evaluate the environmental impact of a given product from its sourcing to its disposal and end-of-life management. This includes obtaining raw materials to manufacturing consumer and industrial products to recycling and waste management.
Why are Life Cycle Assessments important?
Life Cycle Assessments (LCAs) help us better understand the impacts of the materials that we use every day. One study finds that plastics use less water, fewer resources, and less energy to produce and manufacture compared to alternative materials. Additionally, compared to other materials, like glass and aluminum, plastics reduce emissions and increase fuel efficiency, helping an array of industries meet sustainability goals. LCAs help us understand how we can make the best choices to reduce our environmental footprint every day.
After a consumer has used a product, mechanical and advanced recycling technologies (ARTs), like pyrolysis and chemical recycling, work together to ensure that plastic products are reused to produce new durable and versatile products. LCAs have found that recycling is the most environmentally advantageous way to process post-consumer products.
What have Life Cycle Assessments found?
Emissions and Resources
Packaging
Recycling
A 2020 Imperial College of London study reviewed 73 LCAs and most showed plastic performs better than alternatives from a carbon perspective. Several of those studies found materials used as alternatives to plastic packaging – such as cotton, glass, metal or bioplastics – have significantly higher CO2 impact or water usage.
What is driving LCA research?
Industry is dedicated to ensuring that the most environmentally friendly materials are used, especially as sustainability and climate change goals become more important than ever. LCAs comparing plastics to alternative materials show that plastics are in fact the sustainable choice and without plastics, it will be much harder to reach sustainability goals. Industry will continue to invest in research that is vital to ensuring products are sustainably manufactured.
