Single-use plastics (SUPs) ban: supermarkets responses in the implementation of the SUPs ban policy in Surabaya City
摘要
This study explores supermarket engagement in waste management, supermarkets’ preparedness for the 2030 single-use plastic ban, and the implementation of regulations within supermarkets. Secondary data collection identified the research scope of supermarkets, while primary data collection involved measuring the daily rate of supermarket waste generation and analysing its composition. Interviews and focus group discussions with supermarket managers were conducted to gather insights into their participation aspects. Findings show that Surabaya’s supermarkets generate 4.9 tons of waste daily, with plastic film as the most dominant Single-Use Plastics (SUP) type. Approximately 37.5% of supermarkets currently use third-party services to transport waste directly to landfill sites. Although many supermarkets actively implement single-use plastic bag reduction measures, other single-use plastic items, such as plastic film, styrofoam, and cutlery, persist. Only 62.5% of supermarkets are aware of existing regulations, and 40% require further clarification, highlighting a gap in regulatory communication. Most supermarkets express reluctance toward adopting a bulk system due to hygiene, consumer behaviour, and logistical challenges. The study highlights the critical role of multi-level governance particularly government-led outreach and incentives in enabling systemic shifts toward sustainable packaging in the retail sector.
