Abstract

Much research in the Additive Manufacturing (AM) has recently focused on sustainability, including Circular Economy (CE), which is increasingly recognised and supported to reduce environmental harm and the impact of climate change. An aspect of this is the effort to recycle polymers and find uses for the recovered materials. However, when these polymers reach the recycling centre, they may not be in a viable state due to contamination from biological, chemical, or pharmaceutical sources. This is highlighted when considering the polymer waste generated by the medical sector, which necessitate decontamination prior to be reformed into a new product. To ensure continuity with the medical sector, the selected procedure follows the same prescribed methodology. Recovered materials are first cleaned in an ultrasonic bath with triple enzyme detergent, then disinfected with a quaternary disinfectant before being sterilised in an autoclave at 121oC for 30 minutes. This procedure is for decontaminating reusable medical devices and is sufficient for ensuring the reclaimed polymer is suitable for use within the AM industry and wider sectors. The work contained in this paper aims to investigate the effects this procedure has on common polymers and their viability for reuse in AM to support a wider circular economy. We believe that common polymers can be recovered, decontaminated and result in viable filament for use in material extrusion-based AM.
