- University-Wide Zero Waste Strategy: Project Zero Waste drives a holistic approach to waste management, aiming for “Zero Waste to Landfill” through source separation, system design, and community participation.
- Innovative Behaviour Change Campaigns: The “Double Digit Days” initiative successfully turns waste separation into an engaging, lifestyle-driven activity, fostering long-term environmental awareness among students and staff.
- Proven Scalability at Major Events: Implementation during Thammasat Games 2025 demonstrated the project’s effectiveness at scale, diverting significant amounts of food and recyclable waste from landfills.
- Next-Step Climate Action: The initiative now expands into carbon credit accumulation, integrating waste reduction, tree planting, clean energy, and real-time transparency through the Thammasat Carbonfootprint platform.
Thammasat University is accelerating its transformation into a truly sustainable university, guided by a clear vision to reduce its environmental impact and embed sustainability into everyday campus life. At the forefront of this effort is the Property and Sports Management Office (PSM), which leads the university’s flagship environmental initiative, “Project Zero Waste.”
This comprehensive programme addresses waste management through a holistic, end-to-end approach—from encouraging waste separation at the source to achieving the ambitious long-term goal of “Zero Waste to Landfill.” Rather than focusing solely on waste disposal, PSM drives behavioural change through creative engagement, systematic processes, and community-wide participation. As a result, environmental responsibility has become a shared value across the Thammasat community, including students, staff, vendors, and event organisers.
From Waste Crisis to Sustainable Goals
The urgency behind Project Zero Waste emerged from a clear and pressing reality. In 2023, Thammasat University generated an average of 250 tonnes of waste per month, reflecting the scale of operations of a large, urban university campus. PSM recognised that conventional waste management methods would no longer suffice.
In response, the university established a clear and measurable target: “Zero Waste to Landfill.” This goal shifts the focus from simply managing waste to systematically reducing the volume of waste sent to landfills, while maximising reuse, recycling, and recovery. The initiative aligns closely with global sustainability frameworks, including the circular economy concept and climate action goals, positioning Thammasat as an institution willing to confront environmental challenges head-on.
“Double Digit Days”: A Strategy for Engagement
Understanding that lasting change begins with individual behaviour, PSM designed an innovative engagement strategy under the campaign “Separate Before You Throw… Bin it Right.” The campaign reframes waste separation not as a rule or obligation, but as an accessible and engaging daily habit.
To connect sustainability with student lifestyle, PSM drew inspiration from popular online shopping sales days and introduced activities on “Double Digit Days” such as 11.11 and 12.12. This creative concept emerged from close collaboration between PSM and the TU100 (Civic Engagement) course, led by Asst. Prof. Dr Prinya Thaewanarumitkul, which integrates civic responsibility into student learning.
The campaign debuted with the “11.11 Big Pro, Green Heart” event and quickly gained momentum, evolving into a highly anticipated monthly activity. Students and staff bring 1 kilogram of recyclable waste and exchange it for essential household items. This gamified approach transformed waste separation into a positive social activity, fostering cooperation, enjoyment, and shared responsibility rather than enforcement or compliance.
Scaling Up: Waste Management at “Thammasat Games 2025”
The principles of “Separate Before You Throw” were put to the ultimate test during a mega-event: the “Thammasat Games 2025,” held earlier this year from 9–18 January 2025.
Managing waste for a major sporting event is a logistical challenge. PSM implemented a comprehensive waste management system covering 14 sports stadiums, market zones, and food service points.
Post-event data processing was rigorous. After the competitions ended each day, waste was immediately sorted and processed systematically. The results from the 10-day event provided clear, measurable data:
- Food Waste: 2,790 kg (Diverted from landfill and sent for animal feed production).
- Recyclable Waste: 2,045 kg (Sent to recycling facilities).
- General Waste: 55,952 kg (Sent to sorting plants for proper disposal).
This success proves that Project Zero Waste is scalable. Whether it is daily campus life or a national-level sports event, the system works when managed effectively.
The Next Step: Carbon Credit Initiative
The Property and Sports Management Office is not stopping at waste. It is now steering the university towards a Carbon Credit Accumulation Project.
This advanced phase integrates waste management with tree planting initiatives and the transition to clean energy. The aim is to systematically reduce Greenhouse Gas (GHG) emissions. In the spirit of transparency, the university has launched the Thammasat Carbonfootprint website, allowing the community to track and audit the university’s environmental data in real-time.
Cultivating a Culture of Sustainability
Project Zero Waste has proven that solving environmental problems starts with small, individual actions that ripple out to create massive change. By fostering cooperation across the entire community, Thammasat University is ready to stand as a model educational institution that is genuinely committed to the planet.
