Our Mission

Where your voice becomes lasting change.

Eco-lution empowers youth to transform local problems into creative, actionable solutions.
Every voice has power. Every action creates change.

2022 — The Tipping Point

“Climate change is not symbolic.”

— Nayoung Kim, Founder & Former President

“Our school at the time didn’t internally adopt sustainability. No educational curriculum, no policies, no tangible action, no culture.”

Projects & Impacts

To create a youth-led circular ecosystem that transforms café waste into fertilizer, strengthens local soil health, reduces emissions, and reconnects Daegu’s youth with agriculture through hands-on climate adaptation.

Circular model: cafés to Eco-Lution youth to local farms or school gardens and back — turning wasted coffee grounds into fertilizer that restores soil health and reduces emissions

⟨Impact⟩

“Today, youth and farms are very disconnected, so we wanted to cultivate our club members themselves to have hands-on experiences… those experiences were very direct and hands-on. That was my favorite part of the initiative.”

— Yujun Piao, Vice President of Eco-Lution

The Experiment

Turning café waste into biofertilizer

In collaboration with the Daegu Metropolitan Agricultural Technology Center, grounds from local cafés were dried and mixed into compost, then tested against plain soil in the DIS garden.
