Special Issue Information

Dear Colleagues,

The production of value-added compounds from bio-sources is becoming a ground-breaking topic in both research and the industrial world because of the need to adapt the industrial sectors to sustainable, green, and source-saving production systems, as well as in the framework of the circular economy concept. The Special Issue “Green Compounds from Bio-Sources: Characterization, Innovative Production, and Advanced Technological Applications” focuses on the latest developments in the main aspects of the production of green molecules from bio and renewable sources, highlighting all the innovative technologies for their characterization, production, and sustainable application. The ambition of this Special Issue is to publish both reviews and research articles reporting and discussing modelling and experimental approaches on innovative applications for biomass valorisation, advanced technologies for the production of green by-products and value-added compounds, advanced analytical and characterization techniques of bio-molecules, biorefinery for biomass conversion and CO2 capture, and extraction technologies and purification treatments, taking into account the concepts of circular economy and green and sustainable impacts. The production of green compounds can also lead to the formation of undesired by-products that have to be removed from the environment in order to avoid any potential contamination; therefore, this Special Issue is also presenting some advanced technologies for by-product treatment.

This Special Issue aims at providing key information for the industrial sectors in which the valorisation and use of green compounds and bio-sources are fundamental topics such as pharmaceutical production, animal foods, nutraceuticals, and cosmetics.

Polyurethane (PU) is a versatile polymer used in a wide range of applications. Recently, imparting PU with self-healing properties has attracted much interest to improve the product durability. The self-healing mechanism conceivably occurs through the existence of dynamic reversible bonds over a specific temperature range. The present study investigates the self-healing properties of 1,4:3,6-dianhydrohexitol-based PUs prepared from a prepolymer of poly(tetra-methylene ether glycol) and 4,4′-methylenebis(phenyl isocyanate) with different chain extenders (isosorbide or isomannide). PU with the conventional chain extender 1,4-butanediol was prepared for comparison. The urethane bonds in 1,4:3,6-dianhydrohexitol-based PUs were thermally reversible (as confirmed by the generation of isocyanate peaks observed by Fourier transform infrared spectroscopy) at mildly elevated temperatures and the PUs showed good mechanical properties. Especially the isosorbide-based polyurethane showed potential self-healing ability under mild heat treatment, as observed in reprocessing tests. It is inferred that isosorbide, bio-based bicyclic diol, can be employed as an efficient chain extender of polyurethane prepolymers to improve self-healing properties of polyurethane elastomers via reversible features of the urethane bonds.
