Reducing plastic waste from cable ties in food packaging through microbiological testing and behavioral intervention informed by stakeholder perspectives.

Since the onset of the COVID-19 pandemic, the use of cable ties to secure food packaging has become a common practice, potentially contributing to increased plastic waste. This study aims to raise public awareness about the environmental impact of cable ties used in food packaging in Indonesia and promote their reduction. A multidisciplinary approach was used to assess the effectiveness of cable ties in protecting against microbial exposure and to gain insights into consumer and food vendor perspectives. Microbiological testing showed that cable ties did not offer additional protection from microbial contamination on carrier bags, containers, or food surfaces. Interviews revealed consumers were generally indifferent to the use of cable ties, while vendors continued to use them primarily to avoid potential complaints. An educational video was developed to encourage consumers to request that vendors refrain from using cable ties in their orders. While the video increased consumer immediate intention to reduce cable tie use, repeated exposure may be required to translate this intention into actual behavior change. This study highlights the importance of a collaborative model for addressing environmental issues through targeted communication strategies.
