The ECO.NOMIA portal was set up in 2016 as the Portuguese Circular Economy Information Portal. It was one of the components of the 2017 Portuguese Action Plan for Circular Economy, playing the role of a knowledge-sharing space. 

It is a one-stop-shop for all things circular, in Portuguese, and intended for individuals, 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.
