The ECO.NOMIA portal, created in 2016, is one of the components of the Portuguese Action Plan for Circular Economy (2017), adopting the role of a knowledge-sharing space. It is a one-stop-shop for all things circular, in Portuguese, aimed at citizens, companies and investors. Not only does it explain the principles, advantages and opportunities of the circular economy, it also provides examples and information on financing, learning opportunities and national and international events.
