Summary
Students from Qingsong Hou Baoyuan Primary School in Hong Kong have won the overall championship in the youth category at the Geneva International Invention Exhibition in Switzerland with their Biological Green Core Oil Filter device. The four-layer filtration system uses coconut shells to naturally separate grease from water in drainage pipes, preventing blockages while enabling recycled油脂 conversion into eco-friendly soap. The achievement highlights the importance of practical, everyday problem-solving in STEAM education over purely high-tech approaches.
Key Points
- The biological oil filter features a four-layer structure specifically designed to prevent household drainage pipe blockages
- The first layer blocks food residue, the second uses coconut shells to absorb floating油脂 through natural density differences, the third filters remaining impurities, and the fourth discharges clean water
- Collected油脂 can be recycled into eco-friendly soap for dishwashing and household cleaning, while spent coconut shells serve as biofuel
- Primary 6 student Wang Xiyao expressed hope to find better alternative materials to improve the device's practicality and durability
- Teacher Li Donglok, who led the team, observed that Hong Kong STEAM education overemphasizes AI and programming while neglecting practical innovation addressing real societal needs
Why It Matters
The students' achievement demonstrates that practical, everyday innovations can compete with high-tech solutions on the international stage, challenging Hong Kong educators to reconsider STEAM curricula priorities . With many participating students coming from grassroots families and receiving school support through fundraising, this success story also underscores how equal opportunities in innovation education can nurture talent regardless of socioeconomic background .
