As Vietnam enters a critical new phase of mandatory household waste separation, a pioneering education and environmental initiative is being piloted across 16 primary schools in Ho Chi Minh City. Spearheaded by Tetra Pak, this project targets a massive, underutilized source of recyclable material: beverage cartons. The initiative highlights a compelling lesson for the global circular economy, demonstrating that real, systemic change can begin with something as small as a properly sorted milk carton.
Vast Potential and Urban Waste Challenges
According to the Education & Times newspaper, Vietnam generates billions of paper beverage cartons annually. This staggering volume represents a considerable reservoir of recyclable resources. However, the actual recycling rate remains far below its potential, leaving this highly valuable material stream largely untapped in the nation’s push toward a circular economy.
The challenge is particularly pronounced in Ho Chi Minh City, one of Vietnam’s most densely populated urban centers and among its highest generators of household waste. Despite being highly recyclable, beverage cartons are currently among the categories least consistently sorted at the source. The root cause of this issue is not a lack of public awareness, but rather the absence of well-established daily sorting habits and a sufficiently integrated collection infrastructure to close the recycling loop effectively.
The Technology: From Cartons to Eco-Roofing
The recycling potential of this specific material is both real and promising. Through modern processing techniques, the complex composite layers of a paper carton can be efficiently separated and given a second life. High-quality wood pulp fibers are successfully recovered for industrial reuse, while the remaining mixed materials are transformed into practical, durable products such as eco-roofing sheets, compression boards, and stationery. The sustainable circular economy cycle is technologically ready to function; the critical missing link is establishing proper sorting habits at the very first step of disposal.
“Carton for Communities” and Reverse Change Agents
To address this bottleneck, Tetra Pak initiated the “Carton for Communities” program, currently being piloted at 16 schools across Ho Chi Minh City. While the initiative aligns with broader community awareness efforts, it places a highly specific focus on primary school students.
Educational psychologists identify children as powerful “reverse change agents”—individuals uniquely capable of spreading positive behaviors upward to their parents and outward to the wider community far more effectively than the reverse. Field studies conducted across Asia and Latin America have consistently documented this behavioral effect: when children change their daily habits, their families almost invariably follow suit.
A Four-Step Process to Close the Loop
The practical process taught to the students involves four simple, highly effective steps:
-
Drink it clean
-
Tuck in the straw
-
Close the lid
-
Flatten it
Each action takes only seconds, yet makes a meaningful logistical difference. Properly handled cartons save crucial storage space and become valuable, clean feedstock for the recycling chain. What sets this program apart is its design as a complete loop. It seamlessly connects schools, logistics collection teams, and industrial recycling partners into a continuous chain in which cartons travel directly from students’ hands to the processing facility, and eventually back into the community in the form of new products.
Nurturing Identity Over Dry Obligation
Nguyen Do Thu Minh, sustainability manager at Tetra Pak Vietnam—the company spearheading the collection and recycling infrastructure development—identified the core challenge. “In practice, one of the main challenges lies at the source-separation stage,” Minh stated. “Through the ‘Carton for Communities’ programme, we hope to share our experience and foster collaboration between schools, families, and businesses to gradually build a stable collection system – thereby contributing to reduced carbon emissions and more efficient use of natural resources.” Prior to this, the company had successfully rolled out its School Recycling Programme across Bac Ninh and Binh Duong provinces, reaching nearly 1,200 schools.
Bui Duyen, director of SBCC Vietnam (a social enterprise specializing in Social and Behaviour Change Communication) and a key implementing partner, offered a behavioral perspective. “We are not simply teaching students how to sort waste – we are nurturing their identity as protectors of their city,” said Duyen. Using tangible tools like dedicated collection bins and interactive games, the act of handling a carton becomes an inspiring experience rather than a dry obligation.
The immediate impact is already visible in the classrooms. Phuoc Quyen, head pioneer teacher at Dinh Tien Hoang Primary School, reflected on the pilot’s success: “Since the programme launched, our Monday morning assemblies have become far more lively and meaningful. Seeing students remind one another to handle their cartons correctly… is truly encouraging.”
From Classrooms to Macro-Level Change
The pilot across these 16 schools is laying the practical groundwork for refining and scaling the model further. While government regulation can enforce behavior, only education can produce lasting change in values and mindsets. Tens of thousands of tonnes of cartons wait to be given a second life each year. Those macro-level numbers begin with a single milk carton in a child’s hands on a school morning, and the small, sustainable habit that child carries home to the family dinner table.
Meanwhile, in Hungary
To promote environmental awareness and sustainable waste management, the Beverage Carton Association and MiReHu Nonprofit Ltd. have launched a joint beverage carton collection campaign. Exclusively announced for primary and secondary school classes in Miskolc, the educational competition running until the end of May 2026 aims to teach students the practical skills of properly handling composite packaging materials. The most active class that collects the largest quantity will win a special experience program at the Bükk Astronomical Observatory.
Protecting the environment and ensuring sustainability is a shared societal responsibility, and one of the most effective, everyday tools to achieve this is selective waste collection. Although separating paper, plastic, metal, and glass is an increasingly widespread practice in households, the proper handling of beverage cartons still requires focused public education and the mobilization of younger generations. MiReHu’s latest local initiative is designed to fill this gap.
Campaign Schedule and Infrastructural Support
The joint competition organized by the Beverage Carton Association and MiReHu Nonprofit Ltd. officially began on April 20, and the collection period will run until May 31. The organizers are also providing the necessary logistical and infrastructural conditions for the participants: registering school classes can request dedicated collection bags to facilitate the campaign via the official makuka@mirehu.hu email address.
To ensure the smooth organization of logistical processes, a strict deadline has been set: participating competitors must signal their intent to hand over the collected composite beverage cartons to MiReHu no later than May 27, 2026, using the provided email address.
Playful Education and the Grand Prize: The Bükk Astronomical Observatory
The “Bring the box and win!” campaign is built on a classic, quantity-based competition: according to the announcement, the class in Miskolc that collects the highest number of beverage cartons during the campaign period will win the grand prize. The reward for the winning students is a special, experience-rich program at the Bükki Csillagda (Bükk Astronomical Observatory).
According to the organizers, the initiative is much more than a simple competition. The primary mission of the project is to allow young people to learn the fundamentals of environmental awareness in a playful, community-building format, and to recognize the most important core principle of selective waste collection: in a circular economy, every single collected box counts.
