The ‘International Conference on Processing Technologies for the Biobased Products Industries’ (PTF BPI) started in October 2010 at Salzburg University of Applied Sciences in Kuchl, Austria. The conference was intended to provide a forum for discussions among researchers, producers, and consumers of forest and biobased products and acted as a catalyst for new research on product and process innovation that cover a host of subjects for application by technical managers, operations managers, and business managers. The PTF BPI theme for “…providing a forum for discussions among industry technical and R&D directors, and university researchers for the advancement of new technologies….” continues to this day. The conference is held biennially and rotates between Europe and the USA. PTF BPI 2021 at St. Simons Island, GA is the 6th biennial conference and the 3rd in the series in the USA at St. Simons Island. The original PTF BPI 2010 conference resulted in a published proceedings that is still available today (see below). PTF PBI 2016 resulted in a published book of extended abstracts and is available on ResearchGate. We hope you will consider joining us at PTF BPI 2021 to interact with professional colleagues and meet new researchers in an enjoyable and beautiful beachside atmosphere.
