About the RG

The regional group Rhein-Main was founded in February 2017. Our team has expertise in electrical engineering, process engineering, mechanical engineering, architecture and much more. Dedicated new members are always welcome! We do not have a real "thematic focus" because we work on very different projects. So it does not matter which special field you're from, everyone can join us.We meet regularly every second Thursday in Frankfurt/ Main, alternating between a working meeting and a regular's table in various restaurants.

Additional interests

In addition to our actual project work, we also look for topics that we find interesting and important, without being assigned to a specific project. At the moment, we focus on the SDGs of the UN.  

Sustainable development goals

Not too long ago, the United Nations gave itself 17 development goals for sustainable development cooperation, which can also count for us as NGOs. These address the economic, ecological and social level of development and can be found in parts without further action in our projects. We as RG have set ourselves the goal of identifying for each of our projects which of the sustainable development goals we are addressing and how we can achieve further goals.

Ongoing activities and projects

We continue collecting second hand sunglasses, reading glasses and first aid kits for the KCMC hospital in Moshi. On of their ressorts especially cares about people suffering from albinsim as part of the Albino Care Project; people are supported with sunprotecting lotion, sunprotecting hats, magnifying glasses and other items. We first started to support this institution within a dedicated project (TZA_14) and continue this partnership by bringing donations in kind during our other activities in Tanzania.

Apart from that we are still collecting english children's books, which are going to our partner Stawisha Africa in Kenya. There we started a small library, where kids have the opportunity to increase their reading skills (KEN_06). The library shall continue growing over time as we bring further books to Kenya along with our other activites there.
