From Hunger Strike to Policy Shift: How Melati Wijsen Forced Bali’s Hand
In 2013, 12-year-old Melati Wijsen and her younger sister, Isabel, embarked on a hunger strike that would eventually dismantle the plastic bag culture on the Indonesian island of Bali. What began as a childhood protest in a local airport office evolved into a decade-long campaign that pressured the provincial government to implement a landmark ban on single-use plastics. Today, Wijsen’s journey serves as a blueprint for youth-led environmental activism, proving that grassroots pressure can indeed rewrite legislative agendas.
The Architecture of a Grassroots Ultimatum
The Wijsen sisters founded Bye Bye Plastic Bags (BBPB) with a singular, audacious goal: to convince the governor of Bali to declare the island plastic-free. The sisters’ decision to engage in a hunger strike was not a spontaneous outburst, but a calculated escalation after months of being ignored by bureaucratic gatekeepers. They sat on the floor of the Ngurah Rai International Airport, refusing food until they secured a meeting with then-Governor Made Mangku Pastika.
This tactic shifted the power dynamic instantly. By leveraging the visibility of Bali’s tourism-reliant economy, the sisters forced the government to acknowledge the environmental degradation clogging the island’s famous waterways and beaches. The provincial government eventually signed a memorandum of understanding, marking the first time a regional leader committed to a tangible timeline for phasing out plastic bags.
Beyond the Island: Scaling the Plastic Ban
The success in Bali was not an isolated victory; it became a catalyst for national policy. In 2018, Indonesia committed to reducing marine plastic waste by 70% by 2025. This pivot was heavily influenced by the momentum generated by BBPB, which had grown from a local initiative into a global youth movement. The legislative transition was complex, requiring a shift in supply chains for millions of small-scale vendors who relied on cheap, thin-film plastics for daily commerce.
According to United Nations Environment Programme (UNEP) data, the shift away from single-use plastics requires not just bans, but the creation of circular economies. As Dr. Mushtaq Memon, a regional coordinator for resource efficiency, noted in previous assessments of Southeast Asian waste management:
“Policy change is only the first step. The real challenge lies in the transition of informal waste sectors and the availability of affordable, sustainable alternatives that do not place the financial burden on the poorest consumers.”
The Economic Ripple Effects of Environmental Regulation
Bali’s plastic ban exposed the tension between rapid tourism development and ecological preservation. The island, which generates thousands of tons of waste daily, faced a critical infrastructure deficit. The World Bank has noted that Indonesia is the second-largest contributor to marine plastic debris globally, making the BBPB model a vital case study for other archipelago nations. The legislative success in Bali forced businesses to pivot toward biodegradable alternatives made from cassava starch, effectively birthing a new local industry.
However, the transition was not without critics. Small-scale shopkeepers initially struggled with the higher price points of eco-friendly bags. The success of the campaign ultimately relied on public education campaigns that reframed the cost of plastic as a long-term tax on the island’s tourism appeal. As noted by environmental policy analyst Dr. Sinta Dewa, the shift was as much about cultural identity as it was about legislation:
“Melati Wijsen succeeded because she didn’t just talk about waste; she talked about the loss of Bali’s spiritual and physical beauty. She connected the plastic in the ocean to the survival of the island’s core economic engine.”
The Unfinished Business of Waste Management
Despite the legislative wins, the reality on the ground remains a work in progress. While the ban on plastic bags has reduced the volume of thin-film waste, the island still grapples with the wider challenge of plastic bottle waste and inadequate waste-to-energy infrastructure. The OECD recently highlighted that without comprehensive investment in waste collection systems, legislative bans often lead to the substitution of one plastic type for another rather than a total reduction in volume.

Melati Wijsen’s transition from a 12-year-old activist to a global speaker at forums like the World Economic Forum underscores a broader trend: the professionalization of youth activism. Yet, the core of her message remains the same as it was on that floor in the Bali airport. It is a reminder that the most effective environmental policies are often those that start with a refusal to accept the status quo.
