Dr Garden continues: "PLA products are commercially available, but we’ll need to change infrastructure to accommodate these new types of plastics. Despite being a great option for plastics of the future, we don’t yet have the infrastructure for collecting and composting PLA products on a large scale. Chemists, product designers and local government need to start working together to ensure that these innovative solutions actually deliver on their promise."
Dr Garden explains that in future plastics need to be designed with sustainability as a main focus.
"At the moment plastics are designed purely with function in mind – whether that’s strength, flexibility, and so on. We need to start thinking of sustainability as a key necessary property of any product. If there are several materials with similar performance, we should aim to pick the most sustainable one."
