Abstract: Electrical and electronic equipment has become ubiquitous in our everyday life.The increase of waste electrical and electronic equipment (WEEE, 44.6 Mt worldwide in 2016) and the depletion of chemical elements of key importance in the electronic industry (e.g. indium and gallium) have put mounting pressure on the environment. Limited attention has been dedicated to possible WEEE end of life scenarios. The focus has been on device performance, as the technological advances of the last few decades confirm. Refurbishment and recycling of electronic devices have been identified, among others, as economically and environmentally viable solutions to deal with WEEE. Besides that, a promising route towards achieving sustainable (green) electronics is based on the use of abundant materials (e.g. biomolecules extracted from biomass feedstock), novel production schemes (e.g. involving non-toxic solvents) and eco-design of devices that includes biodegradation at the end of life. In this contribution, we will present our preliminary results on the biodegradability and compostability of organic electronic materials of interest for electronics and energy storage devices, focusing on the case of study of melanin biopigments used in transistors, batteries and supercapacitors.

Bio: Clara Santato is Full Professor in the Department of Engineering Physics at Polytechnique Montréal. She earned her PhD degree in chemistry (“Preparation and Characterization of Nanostructured WO3 Films as Photoanodes in Photoelectrochemical Devices”) in 2001 from the Université de Genève and her MSc degree (“Electropolymerization and Photopolymerization of a Pyrrole-Substituted Ruthenium tris (bipyridyl) Complex”) in chemistry in 1995 from Università degli Studi di Bologna. The experimental work was carried out in collaboration with Université J. Fourier. She was a (permanent) research scientist at the Institute for Nanostructured Materials, part of the Italian National Research Council, from 2001 to 2011, and a visiting scientist (2007–2010) at Cornell University, Department of Materials Science and Engineering (Malliaras Laboratory for Organic Electronics). In 2006, she was a visiting scientist with a cross-appointment between the Institut National de la Recherche Scientifique and McGill University (Chemistry), and in 2005, at Purdue University (Chemistry).
Santato’s research focuses on semiconducting films and their interfaces with metal electrodes and electrolytes, for applications in transistors and energy conversion/storage, and has been recently recognized by her elevation to the Institute of Electrical and Electronics Engineers (IEEE) senior membership. With her group, she recently expanded her research interests to green electronic and energy-storage devices.
Santato is a member of the UNESCO MATECSS (Materials and Technologies for Energy Conversion, Saving and Storage) Chair. She serves as editor of the Journal of Power Sources (Elsevier).
