Reducing plastic waste in scientific protocols by 65% - practical steps for sustainable research

Although scientists are generally motivated to adopt sustainable practices in their research, a lack of education is often limiting. Here, I aim to fill this gap by illustrating how to substantially reduce single-use plastic waste in scientific protocols. This article will outline the translation of the three fundamental principles of reduction, reuse, and miniaturization into experimental practice. The transfection of neurons in sterile conditions will be provided as a concrete example to discuss opportunities for change. Simply by reducing, miniaturizing, and reusing, a decrease in plastic waste of approximately 65% was achieved for exchangeable items. This article demonstrates the feasibility of adopting sustainable practices without compromising workflows or data quality.
