Lesson 2: Material literacy is critical
“Designers need to have a new material literacy. They’ve always had to have a palette of materials to work from when they design. In the old days, they needed to understand the physical performance of a material, its visual qualities, its semantics or socio-cultural significance. Now, we need another layer: what are the environmental impacts of the material?
McDonough and Braungart [authors of the influential 2002 book Cradle to Cradle] talk about this. Designers must choose materials and decide which ones to exclude from their palette, based on characteristics such as toxicity, for instance. So just as a designer knows the technical characteristics of a material, they are starting to understand the environmental characteristics as well. For instance, some plastics are now made from wood, which means it will naturally be lower carbon. But a designer still must ask themselves: Do I need this thing to be made of plastic at all and where will it end up?
No matter what the material, all products have an impact. This is why material literacy needs to be combined with ideas like designing for longevity and repairability. If you have something that lasts twice as long, you have halved its impact. Ultimately, reducing our consumption is the best thing we can do for the planet.”
