Twenty-five years ago the first SD card hit store shelves. Since then over 12 billion SD and microSD cards have been sold—yet an estimated 7.2 billion now lie dormant in desk drawers and camera bags. That “sleeping” mountain still holds enough empty storage to stream 16 trillion hours of spoken-word audio.
Audiopedia Foundation’s SD4Africa initiative turns those forgotten cards into offline knowledge hubs for rural women across Africa. With World Environment Day (5 June) fast approaching—and a USD 25 000 boost from the SD Association—now is the moment to get your company involved.
Why SD Cards + World Environment Day = Perfect Match
- Plastic problem, circular solution – Reusing a card avoids new plastic and metals while meeting 2025’s #BeatPlasticPollution theme.
- Low-bandwidth reality – Feature phones with microSD slots are still the most common device for many women in rural communities.
- Audio unlocks access – Audiopedia lessons sidestep literacy barriers and play in local languages, anytime, without data plans.
How SD4Africa Works (in 60 seconds)
- Collect used SD/microSD cards at home or in the office.
- Clean & Load – Audiopedia securely wipes every card and pre-installs health, rights and climate audio.
- Deliver – Local partners distribute the “Hero SDs” to women’s groups who play them on basic phones or solar radios.
One 32 GB card = 2 200 hours of life-saving audio. Imagine the impact of reclaiming just 1 % of the dormant pool.
Ways Your Organisation Can Help
