Access to electricity is a major challenge for many rural communities in Tanzania. According to the World Bank, only about 27% of the rural population in Tanzania has access to electricity, and many of these communities are not connected to the national grid. This lack of access to electricity has a significant impact on the quality of life for people living in these areas, limiting their ability to improve their livelihoods and participate fully in the economy. In addition, many rural households in Tanzania rely on kerosene lamps as their primary source of lighting, which not only exposes them to health hazards but also increases their costs for energy, and negatively impacts the environment. To address this problem, WAGA was founded as a socially responsible company that aims to provide clean and affordable energy to low-income rural communities in Tanzania. Through recycling laptop batteries and creating jobs for local women and youth, WAGA is working to improve the living standards of people in these communities and promote sustainable development.

Our Journey

After WAGA became part of the Open Skies fellows program, we received significant support in the form of funding and mentorship. The funds and guidance provided by the program allowed us to take our recycling and repurposing efforts to the next level.

We started by going to Kariakoo, a large market in Tanzania where many laptop repair centers are located, to collect used and non-functional laptop batteries. Our team of battery collectors, who were mostly local women and youth, were trained to properly handle and transport the batteries to ensure safety during the collection process.

Once the batteries were collected, they were transported to our workshop where they were broken down into their individual components. The batteries were then sorted and tested to determine which cells were still functional and could be used in our products. The non-functional cells were collected together ready for recycling in China, while the plastic housings were sent to our recycling partners.

With the functional cells, we began the process of assembling them into battery packs. Our team of technicians and assembly line workers were trained to properly handle and assemble the cells into various types of battery packs, including 12V, 24V, and 48V packs. These packs were then used in our products such as electric bikes, power banks, solar lights, street lights and battery packs for lighting in villages and power backups in towns.

The support from Open Skies fellows program helped us to scale up our operations and increase our production capabilities. We were able to purchase new equipment and hire more employees, which in turn helped us to create more jobs and support the local community. We are grateful for the support and guidance we received from the program and look forward to continuing our efforts to provide clean and sustainable energy solutions to rural communities in Tanzania.


n addition to our operations, we also used the opportunity to share our knowledge and experience with others. As part of the Open Skies Fellows program, I conducted an outreach event at the Dar es Salaam International Academy on November 17th 2022. During this event, I helped primary school students understand the importance of clean and affordable energy. We also did a hands-on experiment on a topic the students had studied in class related to clean energy.

This outreach event was an exciting opportunity for me to share my knowledge and experience with the next generation. It was also a great way to raise awareness about the importance of clean and affordable energy and the role that recycling can play in achieving this goal. Overall, the support we received as part of the Open Skies Fellows program has been invaluable in helping us to achieve our goals and make a positive impact in the communities we serve.

We also had an outreach event at Muhimbili University with the YUNA club members. During this event, we shared our journey and experience as a socially responsible company working to provide clean and affordable energy to rural communities in Tanzania. We discussed the challenges we faced and the solutions we came up with, including recycling laptop batteries to produce portable power packs. We also shared our commitment to creating jobs and promoting sustainable development. The members of the YUNA club were excited to hear about our work and were eager to learn about the opportunities available for them to make a positive impact in their communities. We encouraged them to unleash their potentials and to explore ways in which they can use their skills and expertise to create opportunities and self-employment, by looking at how WAGA has been working. The event was a great success and we received positive feedback from the members, who were inspired to take action and make a difference in their communities.

Testing Our Power Pack

1. Powering A Local Fruit Shop

We were excited to put our battery packs to the test in a real-world setting and were thrilled when we were able to power an entire local fruits market in Mbezi Makonde, near Mbezi Garden, using just 6 lamps. The shop owners were impressed with the effectiveness and reliability of our battery packs and it was a great validation of all the hard work that our team had put into the project. It was a proud moment for all of us at WAGA and solidified our belief in the potential of repurposing laptop batteries to provide clean and affordable energy to rural communities.
