Abstract

Introduction: Infectious waste handling is a serious problem in healthcare, especially laboratory units. With the increase in research activities, innovative designs are needed that can reduce the risk of contamination and effective solutions are needed for laboratory waste management. Management of infectious solid waste often involves expensive techniques such as incineration, chemical treatment or autoclaving to minimize hazardous substances. Waste left over from laboratory testing activities requires special treatment before disposal. This study aims to test the ability of the waste box equipped with Ultraviolet (UV) in inhibiting the growth of Staphyloccus aereus.

Methods: This study used a simple 2 mm thick acrylic bin model with a Black box height of 50 cm and a base of 1600 cm², equipped with Ultra Violet (UV) C (wavelength 200-280) to inactivate some viruses and bacteria. The bacteria used was Staphylococcus aureus which was characterized through Gram staining, morphology, and biochemical tests.

Results: The study demonstrated the effectiveness of using ultraviolet lamps in the waste box to reduce the growth of staphylococcus aureus bacteria, which is an indicator of infectious waste bacteria.

Conclusion: In conclusion, the use of mini-bin bins with UV lamps can be an effective alternative in handling infectious waste in testing laboratories, but further testing is needed for the recovery of other bacteria, viruses, and fungi.

配备紫外线（UV）的废物箱在减少实验室废物细菌污染方面的效果。

传染性废物处理是医疗保健，特别是实验室单位的一个严重问题。随着研究活动的增加，需要能够减少污染风险的创新设计和实验室废物管理的有效解决方案。传染性固体废物的管理往往涉及昂贵的技术，如焚烧、化学处理或高压灭菌，以尽量减少有害物质。实验室检测活动遗留的废物在处置前需要进行特殊处理。本研究旨在测试配备紫外线（UV）的废品箱对金黄色葡萄球菌生长的抑制能力。方法：本研究采用简单的2 mm厚亚克力桶模型，黑箱高度为50 cm，底座为1600 cm2，配备紫外线（UV） C（波长200-280）灭活部分病毒和细菌。所使用的细菌是金黄色葡萄球菌，通过革兰氏染色，形态学和生化试验进行了表征。结果：本研究证明了在废品箱中使用紫外线灯可以有效地减少金黄色葡萄球菌的生长，金黄色葡萄球菌是传染性废品菌的指标。结论：使用带UV灯的迷你垃圾箱是检测实验室处理感染性废弃物的有效替代方法，但其他细菌、病毒和真菌的回收还需进一步试验。
