Bioplastics need to be properly evaluated before being promoted in healthcare

Perreau-Saussine calls for a rethink of the use of single use plastics in medical schools.1 This is important in order to improve the environmental sustainability of healthcare.The article presents bioplastics as a favourable alternative to single use plastics. Students and health professionals should, however, exercise caution before promoting their use in the curriculum and in healthcare facilities.Beyond the cost of developing a circular economy with bioplastics, there are planetary health matters to consider. Bioplastic production may have important impacts on planetary boundaries. It could, for example, lead to an expansion of agricultural land and increased consumption of water, fertilisers, and pesticides. It could also compete with the food production system.2Like conventional petroleum based plastics, bioplastics can break down into microplastics and nanoplastics throughout their life cycle. These can contain chemical additives and interact with hazardous contaminants.3 The medical literature is increasingly focusing on the problem of microplastics and nanoplastics, and…
