LITERATURE REVIEW 

Literature Summary

In 2015, all member states of the United Nations adopted the "2030 Agenda for Sustainable Development," which includes 17 Sustainable Development Goals (SDGs) as its core. This is a shared blueprint calling for collective action by all nations—regardless of wealth—to improve human lives and protect the planet (2015, United Nations). These goals focus not only on ending poverty and hunger but also on enhancing health and education, reducing inequality, promoting economic growth, addressing climate change, and protecting oceans and forests (2015, United Nations). To realize this blueprint, the UN monitors progress through annual reports and global partnerships (2015, United Nations).

Regarding specific campus waste management practices, research from He-Ping Elementary School indicates that campuses often face excessive litter after being opened to the community on holidays, with general waste accounting for over 50% (2021, Hsieh et al.). The research team suggests that while improved quality of life has brought pollution,  the campus environment can be improved through active waste classification and reduction (2021, Hsieh et al.).  Experiments proved that installing "signboards" and "holiday trash bins" effectively reminds the public and reduces waste by approximately 30%; however, establishing a "student patrol" was less effective, as students felt hesitant to reprimand familiar neighbors or elders in person (2021, Hsieh et al.).

Research from Kaohsiung Medical University provides a social psychology perspective, finding that incorrect recycling among students is primarily due to laziness, time pressure, and a lack of clarity regarding specific classification steps (2013, Chiu et al.). The study highlights that when the "descriptive norm" (a messy environment) conflicts with the "injunctive norm" (poster requirements), people tend to follow the crowd in littering (2013, Chiu et al.). To correct this, the project suggests adjusting slogans to emphasize descriptive norms—highlighting that most people do recycle—while adding emotional appeals regarding the hard work of cleaning staff. Additionally, increasing poster visibility through brighter colors and cartoons can psychologically guide correct disposal habits (2013, Chiu et al.).

Synthesizing these viewpoints, solving waste issues requires translating global policy blueprints into local campus strategies by combining hardware improvements with psychological applications (2015, United Nations; 2013, Chiu et al.). Beyond promoting classification on campus, students should carry these concepts of environmental responsibility back to their families and communities, uniting with friends and relatives to protect environmental cleanliness (2021, Hsieh et al.).

Literature Summary

This case study explores the process of improving road safety around campuses and medical facilities in Surrey, UK.  Research found that in areas with high pedestrian traffic lacking safe crossing facilities, students and vulnerable pedestrians faced an increased risk of traffic accidents. Following years of community petitions and political advocacy,  signalized pedestrian crossings were successfully installed. The study also emphasizes the critical role of reducing speed limits to 20mph and implementing congestion mitigation measures in establishing a safe campus traffic environment.

According to the sources, the core of improving campus traffic safety involves optimizing physical infrastructure and implementing strict speed limit management. In the Surrey case, the absence of appropriate crossing points near schools and nurseries posed a significant threat to the safety of students and parents. To mitigate this danger, advocating for 20mph low-speed zones is a vital strategy for ensuring road safety, as lower vehicle speeds significantly enhance protection. In our research project, we can adopt this model by requiring all faculty and staff to maintain a speed below 20mph on campus, thereby giving students more time to react to vehicles. These practices demonstrate that addressing safety concerns at the intersection of parking lot entrances and sidewalks requires a combination of structural solutions—such as signalized crossings, low-speed zone planning, and traffic flow management — to successfully achieve traffic safety objectives.

Literature Summary

According to the United Nations Environment Programme (UNEP) and the World Health Organization (WHO), there has been close attention in recent years to the hazards cigarette butts pose to the environment and public health,  emphasizing their impact on smoke-free campuses. Cigarette butts are not merely a litter problem; they are highly toxic plastic waste and an invisible killer of young people's health. They contain tar, nicotine, heavy metals (such as arsenic and lead), and hundreds of toxic chemicals. When discarded, rainwater washes these toxins into campus soil and water, polluting the local ecosystem.

The vast majority of cigarette filters are made of plastic (cellulose acetate), taking years or even decades to decompose and turning into microplastics. These residues can be ingested by organisms within the campus ecology,  eventually harming the general public through the food chain. Although the "Tobacco Hazards Prevention Act" mandates that schools be smoke-free indoors and outdoors, many sidewalks around campuses are not included in these restricted zones. Smokers at school entrances cause second-hand smoke to drift onto campus. Even after the smoker leaves, chemical residues (third-hand smoke) continue to release toxins, adhering to sports fields and sidewalks, which may lead to respiratory diseases or other health issues for students.

Furthermore, carelessly discarding unextinguished cigarette butts can easily ignite dry leaves, trash bins, or surrounding debris, posing a serious public safety hazard. Littering cigarette butts around the campus also violates the "Waste Disposal Act," punishable by fines between NT$3,600 and NT$6,000, and negatively impacts the overall image of the school community. Addressing this waste management issue is essential for bridging the gap between awareness and environmental responsibility to create a better community for all.
