Given the recent escalation of events related to COVID-19 the Conference BSE 2020 was held online in the ZOOM-based platform. The event was a true success and we counted with about 200 participants from all over the world.

The event started with the opening statement from the Rector of Estonian University of Life Sciences, Urmas Klass Mayor of Tartu and Margus Arak Director of the Institute of Technology of Estonian University of Life Sciences

The plenary session was delivered by Prof. Fadi Dohnal, from Private University for Health Sciences, Prof. Mohamed Bouaziz from Higher Institute of Biotechnology of Sfax, Tunisia and Dr. Jorge Ferreira from the Department of Resource Recovery and Building Technology University of Borås, Sweden.

After that, we had parallel sessions in the fields of Bioenergy, Renewable Energy, Nanomaterials and Waste Recovery, Food technology, Precision Agriculture, Agricultural and Livestock Engineering, and Engineering. We had 51 presentations from North America, South America, Central Europe, Scandinavia, Baltic countries, and Eastern Europe.

The poster session will be held online from May 6^th until May 8^th. All the participants are welcome to check the posters, make questions and leave comments in the sections created in each poster for this end. We had 69 posters from South America, Central Europe, South Europe, Northern Africa, Middle East, Baltic countries and Eastern Europe.
