Green Composites Based on Mater-Bi® and Solanum lycopersicum Plant Waste for 3D Printing Applications
2023
3D printability of green composites is currently experiencing a boost in importance and interest, envisaging a way to valorise agricultural waste, in order to obtain affordable fillers for the preparation of biodegradable polymer-based composites with reduced cost and environmental impact, without undermining processability and mechanical performance. In this work, an innovative green composite was prepared by combining a starch-based biodegradable polymer (Mater-Bi®, MB) and a filler obtained from the lignocellulosic waste coming from Solanum lycopersicum (i.e., tomato plant) harvesting. Different processing parameters and different filler amounts were investigated, and the obtained sample…
Tissue Engineering Biopolymers
2011
Tissue engineering has always been a multidisciplinary research area focused on tissue regeneration and restoration of organs function, through implantation of cells or tissues growing outside the body. According to increase in knowledge of the interactions between living organisms and biomaterials, development and diversification of biocompatible devices has brought the world of medicine to what has been the greatest therapeutic revolution of our times. The main challenge of biomaterials is not only related to "tolerance-biocompatibility" by the body but also in its functionality. A biomaterial must be able to positively interact with tissues and exercise those functions for which it was d…

Biopolymer Recovery from Aerobic Granular Sludge and Conventional Flocculent Sludge in Treating Industrial Wastewater: Preliminary Analysis of Differ…
2022
The recovery of biopolymers from sewage sludge could be a crucial step in implementing circular economy principles in wastewater treatment plants (WWTP). In this frame, the present study was aimed at evaluating the simultaneous production of polyhydroxyalkanoates (PHA) and extracellular polymeric substances (EPS) obtainable from the treatment of agro-industrial wastewater. Two biological enrichment systems, aerobic granular sludge (AGS) and a conventional activated sludge operating as a sequencing batch reactor (SBR), were monitored for 204 and 186 days, respectively. The maximum biopolymers accumulation capacity was close to 0.60 mgPHA-EPS gVSS−1 in the AGS when operating at 3 kgCODm…
