Sustainable life cycle design aspects: how aware are material scientists?

When developing new materials many aspects of sustainability are relevant, especially when the ultimate goal is mass production. More efficient energy storage and transmission are important parts of a larger product life cycle design and the confines of the circular economy, including environmental and social concerns. For example, due to environmental, geopolitical, and health concerns, it is important to choose materials that are easily accessible, as opposed to materials requiring complicated extraction, storage, and transportation methods. Equally important is the abundance of the material, as the mass production and use of a product are not sustainable if its raw components are scarce. This requires material scientists to be aware of how their design affects the later life cycle stages of the materials they develop. Very few studies cover whether material scientists take these type of questions into consideration. To resolve this, material scientists were questioned on various sustainability aspects. Results show that most of the questioned scientists have little to no awareness of what effects mass production of their developed materials might have regarding greenhouse gases or the workforce, or what their material’s recyclability or longevity might be. The results indicate that these questioned material scientists are not fully aware of several imperative sustainability aspects and do not fully consider the impacts of their designs. To increase instilling and evaluating awareness of sustainability aspects on life cycle design, two improvements are: increasing sustainability education by lifelong learning, and adding sustainability concerns as a required component to grants and funding.
