About

SolarSack is a Danish impact-based start-up. SolarSack's vision is to bring safe and affordable drinking water to the 2.2 billion people in the world who do not have access.
The History

Alexander Løcke developed the first SolarSack on a research trip to the Adjumani refugee camp in Uganda as part of his Master’s thesis project in Industrial Design Engineering.

While spending time in the refugee camp, it was clear to him that the area struggled with deforestation as the residents were forced to cut down trees to boil water to purify it. This sparked the idea to develop an alternative to boiling water that would not impact the environment negatively while still providing safe and clean water to the residents.

After several workshops with local residents, learnings were obtained about their habits and needs for purified water. Using the sun as a key resource, the Solar Water Disinfection method was combined with the development of a high tech plastic material resulting in the invention of the SolarSack.

The Impact

More than 2 billion people in the world do not have access to clean drinking water. Some boil to clean their water, leaving an incredibly negative impact on the environment, while others cannot afford to buy wood fuel and live with the risk of getting sick.

Safe Water (SDG 6)
By providing an affordable water purifying solution, SolarSack decreases the number of people that get sick or die from water-borne related diseases. Doing this adds to the social and economic development of small households by reducing sick days and lost income, reduce money spent on healthcare, and further increase children’s school attendance due to improved health. SolarSack makes safe water accessible to the people living at the bottom of the wealth pyramid. 

Environmental (SDG 13 and SDG 15)
Boiling water using wood fuel contributes to millions of tonnes of CO2 emissions globally. Implementing the SolarSack in areas dependent on wood fuel, dramatically reduces end-user dependency on it, which in turn reduces rates of deforestation and CO2 emissions. More concretely, every SolarSack that substitutes wood fuel will save two trees worth of fuel and save more than 500 kg in CO2 - proving a big potential for the SolarSack to mitigate climate change.
