What made ÖKOINDUSTRIA 2021 a full-fledged online event?

A state-of-the-art software provided the perfect technological background, thus the virtual conference space had plenty of experiences in store for you that a traditional, on-site expo could hardly offer. 

Throughout the three days thematic roundtables, sessions alternate d meanwhile the virtual expo was open.

The cream of the events and presentations was streamed and recorded by a professional team working at remote locations, and you felt as if you enjoyed the show in person, from the first row. The internet requirements do not exceed the ones to watch Netflix or YouTube.   

All this with ease, from the comfort of your office or home. This year, ÖKOINDUSTRIA is really left the smallest possible ecological footprint.

The 3-day event is again an excellent opportunity for companies and green innovators to meet potential investors, partner meetings, or to organize thematic round tables, sections and conferences.

We welcomed Hungarian and international companies, professionals, trade professionals, investors, non-governmental and non-profit organizations, career starters and career changers who live in the green industry or are planning their future here.
