About me

My current focus is to develop large-scale protocols for producing biohybrid protein/lignocellulosic materials with useful properties as biodegradable ab(d)sorbents using industrial biomass as raw material (waste valorisation). My overall goal is to produce solutions within the "Waste to useful Products W2P" frame and the cradle-to-cradle circularity model for product design (raw material, processing, end-of-life).

My ultimate goal is to foster collaboration among actors interested in developing sustainable Sanitary Solutions and addressing the hygiene industry's negative environmental impact. I believe this can be achieved by bringing together diverse stakeholders and collaborators united in their commitment to creating solutions that contribute to a circular and sustainable economy.

My interests lie within the fields of research, education, teaching, and society.

I am also a member of the LGBTQI+ and Allies Network at KTH 🏳️‍🌈. My pronouns are he, him. You can call me Antonio.

  • Transformation of industrial biomass intofunctional materials andnetworks.
  • Biomacromolecules and their use as raw material for producing porous absorbent networks.
  • Circular economy principles for material development.
  • Protein/cellulose interfacesfor the production of biohybrid networks.
  • Upcyclingof biomass and biopolymer streams and material adaptation.

My research vision goes in hand with the Sustainable Development Goals (SDGs) 9, 11 and 12. For more info, read more here.

Dr. Capezza earned his double Ph.D. in 2020 from the Royal Institute of Technology (KTH) and the Swedish University of Agricultural Science (SLU). The topic of the Ph.D. work was Superabsorbents from Agricultural Products. Previous to his doctoral studies, he developed an interest in polymeric materials when working withConductive Natural Rubber Nanocompositesin KTH (2014-2015). Capezza's doctoral studies on protein superabsorbents werepatentedin cooperation with Essity AB in 2020. Capezza worked in 2019 as Project Coordinator and main applicant in the Vinnova Challenge Driven Innovation program "Sustainable Superabsorbents". The project aimed to pilot-scaling the results published in his Ph.D. thesis and resulted in an established constellation of 12 industrial/academic partners interested in exploring the materials for future applications.

Capezza is conducting his postdoctoral studies on the topicExtrusion of Superabsorbents for Hygiene Applicationsas principal investigator in KTH Olsson's group (BoRydins Stiftelsen for Independent Research, Grant F30/19) in theDepartment of Fibre and Polymer Technology. The focus of his project is to develop large-scale protocols for producing hygiene articles using industrial biomass/waste for raw material valorisation. The research is directed towards making useful hygiene products from waste (Waste To Products W2P), considering the circular bioeconomy and sustainability of the products (raw material, processing, end-of-life).
