Zero Waste Campus

A green campus movement aimed at minimizing single-use items and waste on university campuses and building a circular economy system

Zero Waste Campus

Overview

Zero Waste Campus (제로웨이스트 캠퍼스) is a green campus movement that seeks to fundamentally reduce the waste generated on university grounds and to minimize the amount of resources headed for landfill or incineration through reuse, recycling, and composting. Going beyond a simple environmental campaign, it aims to redesign the systems across purchasing, food service, administration, facilities, and education as a whole into a circular economy structure. Because universities are both living spaces where large populations gather every day and educational and research institutions, they are regarded as testing grounds where both the effects and the ripple power of zero waste practices are large.

Concept and Definition

Zero waste is a concept that practices a five-tier priority (Refuse, Reduce, Reuse, Recycle, Rot) under the principle of "do not burn or bury waste." When applied to a campus, it means breaking away from the existing "collection- and treatment-centered" environmental management and shifting to preventive management that blocks waste generation from the purchasing stage. The Zero Waste International Alliance (ZWIA) grants zero waste certification when the waste going to landfill, incineration, or environmental pollution is less than 10 percent of the total, and some universities are taking on this standard.

Background of Its Emergence

Since the 2010s, as responses to the climate crisis and ESG management spread, demands for universities' social responsibility grew. In particular, after COVID-19, delivery and packaging culture surged, causing a sharp increase in single-use plastic use on campuses, and student self-governance organizations and environmental clubs began raising the issue in earnest. In addition, as sustainability came to be reflected in the government's carbon neutrality policy and university evaluation indicators, more universities established organizations or dedicated departments directly under the president.

Key Implementation Elements

1. Phasing out single-use items: Banning the use of plastic cups, straws, and plastic bags at on-campus cafes and stores, and replacing them with paper or reusable items.

2. Reusable container circulation system: Establishing collection infrastructure that includes lending and returning reusable cups and tableware, as well as washing and disinfection. Deposit systems or point-accumulation methods are often used.

3. Refill stations and tumbler promotion: Installing refill stations for bottled water, detergents, and daily necessities, and offering discounts and points for bringing a tumbler.

4. Improving separate disposal infrastructure: Day-of-week and item-specific disposal guidance, dedicated collection bins for transparent PET bottles, and composting of food waste (linked to campus gardens).

5. Administrative and purchasing innovation: Introducing green purchasing standards, making academic events paperless, setting double-sided printing as the default, and operating a lending library for event supplies.

6. Expanding education and participation: Environmental education at freshman orientation, links with liberal arts courses, "green leader" supporters, and department-level practice competitions.

7. Waste data management: Measuring and disclosing emissions by building and department, and publishing performance reports against targets.

Representative Cases

In Korea, Seoul National University, Yonsei University, Korea University, KAIST, and Hanyang University, among others, have operated reusable container adoption, single-use cup-free cafes, campus markets (secondhand goods sharing), and campaigns to collect discarded clothing and waste electronics. Overseas, some universities in the United States have declared target years for zero waste and institutionalized composting of restaurant food scraps and reuse of goods, while European universities sometimes run Repair Cafés on campus on a permanent basis.

Performance Measurement Indicators

Key indicators include waste generation per capita, recycling rate, food waste rate, reduction in single-use item use, reusable container return rate, and greenhouse gas reduction (CO₂eq). Recently, the trend is to calculate together not only simple emissions but also a resource circulation index covering the entire process of purchasing and disposal.

Limitations and Challenges

Typical difficulties include the water and energy required to wash reusable containers, hygiene management, securing budgets, the sustainability of student participation, and maintaining infrastructure during vacations. In addition, equity issues with private commercial districts outside campus, the lack of cooperation with delivery platforms, and the impact of policies easing single-use item regulations also act as variables. Above all, settling into a permanent operating system based on institutions, budgets, and data—rather than a "one-off campaign for an event"—is cited as the key task.

Latest Trends

In 2024–2025, there is a clear trend of the Zero Waste Campus evolving beyond individual practices into institution- and data-based management. First, a "campus–community circular economy model" that links reusable container circulation services with private startups and expands them beyond campus into the local community is spreading. Second, with the introduction of AI- and IoT-based smart collection bins and emission measurement systems, cases in which waste data is disclosed on real-time dashboards have increased. Third, as zero waste indicators have been formally incorporated into university ESG disclosure and carbon neutrality roadmaps, more universities have established dedicated organizations directly under the president. Fourth, attention is being paid to "practice-based credit" programs linked to climate and environment liberal arts courses and to student-led projects in the Living Lab style. Fifth, some universities are attempting third-party verification and international certification in order to avoid greenwashing controversies. On the other hand, cases have also been reported in which the scale of campaigns has shrunk due to economic downturn and budget cuts, or operations have been halted due to low reusable container return rates, leaving the design of participation incentives and the securing of sustainable funding as the biggest topics of 2025.
