Our Story

SolarSack is a Danish based impact start-up. Our mission is to bring safe and affordable drinking water to the 2.2 billion people in the world who currently lack access to clean water.

The first SolarSack

was developed by Alexander Locke during a research trip to the Adjumani refugee camp in Uganda, 2017.

The main aim was to develop an alternative to boiling water that would not negatively impact the environment while still providing safe and clean drinking water. After several workshops with local residents, Alexander was able to prototype an improvement to the Solar Water Disinfection (SODIS) method in a multi-layered plastic bag composition that allowed purification using only the sun rays.

This was the invention of SolarSack.
