Net zero on 3D printing filament recycling: A sustainable analysis

Abstract

As global concerns about climate change and resource scarcity grow, the need for sustainable practices in manufacturing is becoming increasingly important. 3D printing, a rapidly developing technology, has the potential to mitigate environmental impacts by reducing material waste and enabling decentralised production. This article investigates the sustainability of 3D printing filament recycling, focusing on achieving net-zero emissions. We analyse the environmental impact, energy consumption, and potential for reducing waste in filament recycling and provide recommendations for improving sustainability. Recycling these filaments has been identified as a potential solution to reduce the amount of plastic waste generated. This paper explores the concept of achieving net zero on 3D printing filament recycling, focusing on the sustainable analysis of the process. A literature review was conducted to understand the current state of 3D printing filament recycling and the challenges of achieving net zero. The review was supplemented with interviews with industry experts to gain a more in-depth understanding of the challenges and potential solutions. The results show that achieving net zero on 3D printing filament recycling is possible. However, it requires a holistic approach that considers the entire lifecycle of the filament. The paper discusses the implications of achieving net zero on 3D printing filament recycling for sustainability and the circular economy.
