We are working for sustainable urban transition

We are a multidisciplinary collective passionate about global sustainable development. We want to enable a smoother urban transition by co-creating sustainable solutions to the wicked challenges of our world together with various actors and experts.

Wicked challenges are environmental, social and economic problems such as waste, food security, poor sanitation and access to safe water.

Our vision

We envision a world in which every person enjoys fully his or her human rights and lives in harmony with nature and the environment.

Our mission

We work with people from different academic and cultural backgrounds to create innovative and sustainable solutions to the wicked problems our world faces today. We focus on re-thinking existing policies and practices to design strategies and initiatives that contribute to a smoother global transition.




What we do

We help urban communities in low-income settlements to build a sustainable future for themselves

We work together with local communities in urban settlements to plan and implement initiatives that aim at addressing the wicked problems.  Our first projects are in Tanzania and deal with water, sanitation and agriculture.

Our solutions involve and will always involve a sustainable business aspect. By bringing in entrepreneurship we want to ensure local ownership and make a long term impact.

Improving sanitation by building community capabilities in urban settlements of Tanzania

The project aimed at improving the sanitary situation of people living in informal settlements of Dar es Salaam where around 80% of the population lack proper sanitation and water services. Living in these informal settlements people do not have resources to improve their living conditions.

The project team  introduced ecological sanitation  technologies and composting methods to the local community and trained them on construction, maintenance and operation of ecosan toilets. With the support of the project local communities built as many as 38  ecosan toilets for low-income families in three informal settlements around Dar es Salaam.

This project has helped the community.  At the beggining, it helped the youth of Keko Machungwa who were in drugs, by giving them life alternatives. Youth learned construction skills and benefitted from one dry toilet that served as a pilot of the dry toilet technology and as an example for the whole community” says Husna Seif Sechonge, leader of the Feferation of Urban Poor and resident of Keko Machungwa.

The project built the grounds for the establishment of a local social enterprise run by local communities to produce fertilizers and soil amendments harvested from ecosan toilets. Members of the project with business knowledge educated and adviced the local community on basic business skills and principles of sustainable economies.

Get involved

We welcome you to work with us and re-think ways to a smoother urban transition

Coming soon: Buy urine collection services in Dar es Salaam

In the near future we will offer the possibility to split the costs of waste collection in Dar Es Salaam with the local community members.

As a citizen from anywhere in the world, you can pay 5 euro or more for the collection and recycling of urine as a fertilizer in Dar es Salaam. It is a meaningful way to participate in making the city lush and healthy for its citizens.

Urine is a perfect fertilizer containing precious minerals and plant nutrients that the world is soon running out of.  By paying for the fee for urine collection you participate in changing the way we grow our plants and eat them for the better.

Participate in our projects

We believe in the added value of multidisciplinary teams where different  skills, knowledge, experience and cultural background complement each other for a better end result.  We invite students, university programs, business experts, architects, designers, social workers or anybody with a passion to re-think urban transition to contribute.

Our  latest collaboration is with Aalto University Students. Have a look

We are constantly looking for teams or individuals to join us for longer or shorter periods – on a voluntary basis or else (depending on the available funds).  If you are  interested in experimenting and finding solutions for urban problems, or have a ready idea and existing clients, get in touch and share what you have in mind.

Invest in our solutions

We are looking for funding for our future projects. We are a small entity and all our  funds will go directly to the on-going projects.
