3R (Reduce, Reuse, and Recycle) Program for the University’s Waste
An example of 3R program for the university’s waste
Overview
Our university continues to champion sustainability by actively implementing a comprehensive 3R (Reduce, Reuse, Recycle) program. This initiative aims to cut down on overall waste generation, promote efficient resource use, and embed eco-friendly habits into our campus culture.
Reduce — Minimizing Paper Usage
We’ve fully rolled out an electronic document management system across 100% of departments, replacing traditional paper workflows.
This transition allows staff and students to send, store, and manage documents digitally, reducing paper dependency while streamlining administrative processes.
By going paperless, we are directly shrinking our environmental footprint and inspiring the entire campus to embrace greener practices.
Reuse — Promoting Resource Consciousness
All departments are now actively involved in resource-reuse initiatives (100% coverage).
We encourage double-sided printing (only when necessary), repurposing existing materials, and consistently opting for reusable plastic or cloth bags over single-use ones.
This collective effort strengthens our community’s mindset of resourcefulness and reinforces our long-term commitment to sustainability.
Recycle — Sorting and Diverting Waste
Waste-sorting systems have been launched across campus, with 35% of departments fully implementing them so far.
Staff are encouraged to separate recyclables (like plastic bottles and paper), which are then sold to local recycling companies—supporting the circular economy.
In partnership with municipal recycling facilities, we ensure all collected materials are processed responsibly and efficiently, reducing landfill burden and promoting sustainable waste cycles.
Impact & Ongoing Commitment
Even at this early stage, our 3R efforts have already reduced the amount of paper, plastic, and general waste generated on campus.
We are committed to expanding the reach of recycling systems and strengthening engagement from all departments to achieve full implementation.
Current average 3R implementation rate: Average (100 %+100 %+35 %) = 78 %
We remain dedicated to pushing this number higher each year as part of our long-term environmental stewardship goals.

Program to Reduce the Use of Paper and Plastic on Campus
An example of a department's contribution to promoting the university's Green University Policy.
Recognizing the importance of environmental stewardship and its contribution to sustainable development, the university is firmly committed to implementing effective waste management practices. To support this goal, the university has issued a policy encouraging all departments, personnel, and students to adopt the following measures:
- Minimize printed paper usage and print documents only when necessary.
- Promote the use of personal drinking glasses or tumblers to reduce dependence on paper and plastic cups.
- Encourage the use of cloth bags instead of single-use plastic bags.
- Advocate for double-sided printing to conserve paper resources.
- Promote the use of electronic document systems for administrative and academic tasks.
- Encourage the reuse of plastic bags and bottles to extend their life cycle.
- Promote the use of electronic media for textbooks and teaching materials.
- Encourage the use of personal food containers instead of disposable paper or plastic plates.
- Reduce paper consumption in administrative activities and curriculum development processes.
- Support the design and use of products made from natural or recycled materials.
- Implement waste sorting policies to facilitate the recycling of reusable materials.

Organic Waste Treatment
As outlined in Section 3.7, Rajamangala University of Technology Phra Nakhon recognizes the environmental impacts of organic waste generated on each campus and within the surrounding community. To address this, the North Bangkok Campus has implemented a program that allows food stall operators and local farmers to collect leftover food for use as animal feed. Through this initiative, approximately 25.8% of the total organic waste produced across all campuses is repurposed, rather than being disposed of through open dumping.
This practice not only reduces the volume of organic waste sent to landfills but also supports local agricultural activities, demonstrating the university’s strong commitment to sustainable and circular waste management strategies.
