Abstract

3D printing is an important part of many university makerspaces. However, it comes with negative environmental consequences, including polylactic acid (PLA) filament waste. Currently, the MakerLab at Binghamton University has no closed-loop recycling system, leading to large quantities of used filament being sent to landfills, where it contributes to greenhouse gases and microplastic production.

This research project looks at the feasibility of an in-house PLA filament recycling program by examining the mechanical recycling process, cost/equipment needs, contamination issues, available space, and the effect of repeated recycling on the filament. An economic analysis will be completed through a break-even analysis and a return on investment analysis using waste volume information. Environmental impacts will be assessed based on PLA degradation, greenhouse gas emissions, and microplastic production. This research is anticipated to provide an evidence-based decision for the environmental value and viability of recycling PLA materials at the Binghamton University MakerLab.
