Reprocessing Zamak laryngoscope blades into new instrument parts; an 'all-in-one' experimental study.

ABSTRACT:

Introduction

Disposable instruments in healthcare have led to a significant increase of medical waste. The aim of this study is to validate the recycling of disposable Zamak laryngoscope blades into new medical components by using a new 'all-in-one' affordable reprocessing setup as alternative for die-casting.

Methods

A n "all-in-one" casting set-up was designed and built. Laryngoscope blades, recovered from two hospitals, were disinfected, melted and cast into dog-bones and into new instrument parts. The quality of the cast material was evaluated using X-ray fluorescence spectrometry. The mechanical properties were obtained by assessing the Ultimate Tensile Strength (UTS) and tensile tests.

Results

A recovery of 93 % Zamak was obtained using a melting temperature of
