Developing Bioplastic Packaging that Improves User Convenience using Human-centered Design Engineering Processes

Novel environmentally friendly alternatives for packaging materials such as bioplastics are being developed to mitigate problems with petrochemical plastics but. Low acceptance of these bioplastics among consumers and other have delayed their adoption. Through a mixed method approach this work aims to assess the factors contributing to the low adoption rates of bioplastics as a way to inform development of more highly accepted bioplastics. Stakeholders with a variety of links with the packaging/plastic industries were interviewed using a semi-structured interview approach and the results were analysed to discover recurrent themes and perceptions regarding packaging. From this thematic analysis a survey was conducted to explore consumer opinion. The findings indicate that though the population is aware and interested in changing to environmentally friendly packaging confusion exists as to what that means and what are be best ways effect that change. The teenager group was identified as the most susceptible to be involved in the change. Frequently cited barriers to acceptance centred on separation of waste and access to correct waste bins. The characteristics likely to lead to a higher acceptance of novel bioplastics were time of decomposition (6 to 8weeks), small thickness, and possibility of being introduced in current processes of packaging preparation, among others.
