On June 5th, World Environment Day, a themed event titled “Green Packaging, Low-Carbon Living” was held at the School of Environment, Tsinghua University. The event was jointly organized by Vitasoy Co., Ltd., Tsinghua University Xiuzhong College, Tsinghua University School of Environment, China National Resources Recycling Association, and Beijing Resource Compulsory Recycling Environmental Protection Industry Technology Innovation Strategic Alliance, and hosted by Tsinghua University Student Zero Carbon Future Association and Tsinghua University Student Green Association. The event featured an exhibition of recycled cultural and creative products made from beverage paper-based composite packaging (hereinafter referred to as “paper boxes”), an interactive activity where participants could collect paper boxes to redeem gifts, and a poster exhibition on paper box recycling and resource utilization technologies. The event attracted many Tsinghua faculty and students, vividly showcasing the concept of green recycling on campus.
This event is a phased demonstration of the “Beyond the Classroom” practice at Tsinghua University’s Xiuzhong College. In September 2025, Vitasoy officially partnered with the “Beyond the Classroom” project, joining as a supporting organization in the co-construction of the paper packaging recycling project. As an important component of the scientific research and innovation practice at Tsinghua University’s Xiuzhong College, “Beyond the Classroom” is a unique training program established by the college outside of the main classroom, encouraging students to step outside the classroom and conduct interdisciplinary explorations around sustainable development issues. This research on paper packaging recycling is one important practical project within this program.
Over the past year, Tsinghua students participating in the project have conducted field research in Hangzhou, Beijing, and other locations to understand the industrial pathways of paper packaging recycling and regeneration. In Hangzhou, students visited the Lianyun Environmental Recycling Resource Sorting Center, observing firsthand how artificial intelligence accurately identifies and sorts paper packaging; they also visited Hangzhou Fulun Ecological Technology Co., Ltd., gaining an in-depth understanding of how the patented “paper-plastic-aluminum separation” technology transforms waste packaging into recycled paper, plastic, and aluminum products. In Beijing, students visited the Aihuishou Tongzhou District Recyclable Waste Sorting Center and Tetra Pak Packaging (Beijing) Co., Ltd. to gain a deeper understanding of the complete chain from front-end green design to back-end recycling systems.
These practical findings were presented at the “Sustainable Development Observation” Beyond Classroom Results Presentation on June 5th. The three research findings focused on raising public awareness of community recycling, analyzing the input-output of the economic value chain, and optimizing paper-plastic-aluminum separation technology, providing youthful perspectives and insights into the recycling of paper packaging boxes from different dimensions. “Beyond Classroom” special scholarships were also awarded at the event to encourage more students to engage in sustainable development practices.
A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine. I am so happy.
my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents.
I feel that I never was a greater artist than now. When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary.
