Swipe to see 300+ students turn kitchen waste into race car fuel! 🏎️💨

Last week at NAIS, things got hands-on, a little messy, and totally amazing. We challenged the students to take everyday food waste—like leftover eggshells and used cooking oil—and literally transform it into clean, working biofuel.

The ultimate test? Pouring their custom green energy into toy cars and racing them to the finish line. 🏁

When kids actually build and test these solutions themselves, the concept of a "circular economy" instantly clicks. They aren't just reading about renewable energy—they are engineering it.

But biofuels are just the beginning! At AlGreen, we turn classrooms into living labs. We’ve brought hands-on STEM to over 1,300+ students across 7 schools in Hong Kong, exploring:
🌱 Sustainable Agriculture
💨 Carbon Capture
🫧 DIY Algae Air Purifiers

💡 Teachers and Parents: What environmental problem would your students want to solve first? Let us know below! 👇

☀️ Summer Bookings Are Open! We are currently taking trial bookings for schools and summer camps. We bring the curriculum, the lab equipment, and the energy. Send us a DM to lock in your dates! 📩.
