Polyurethanes (PU) are one of the most-used classes of synthetic polymers in Europe, having a considerable impact on the plastic waste management in the European Union. Therefore, they represent a major challenge for the recycling industry, which requires environmentally friendly strategies to be able to re-utilize their monomers without...

Regioselective enzymatic polycondensation of the bio-based cellulose derived polyol, Triol-citro, and dimethyl adipate using Candida antarctica Lipase B (CaLB) was investigated. A Design of Experiment approach with MODDE (R) Pro 13 was used to determine important factors in the branching behavior of this polymer, and reactant ratio,...

: This work aims at improving and disclosing new properties of films based on polylactic acid (PLA) and a star-shaped polycaprolactone (PCL). Indeed, previous works demonstrated that the presence of ad-hoc synthesized PCL, characterized by low molecular weight and carboxyl end groups (coded as PCL-COOH), improves the elongation at break of the...

: Given the urge to accelerate the substitution of petrol-derived solvents not only in more traditional fields like pharmaceuticals, personal care, or electronics but also in innovative research processes, this work focuses on the utilisation of four biobased solvents as media for the enzymatic synthesis of aliphatic-aromatic polyesters. As...

Vitrimers represent an environmentally friendly class of materials, which behave like thermosets at room temperature but exhibit thermoplastic flow behavior when heated, making them processable and recyclable, thus extending material life and reducing waste. However, to fully meet the current demand for a sustainable economy, biodegradability...

Poly(ethylene 2,5-furanoate) (PEF) is considered to be the next-generation green polyester and is hailed as a rising star among novel plastics. It is biobased, is nontoxic, and has comparable or improved properties compared to polyethylene terephthalate (PET). Biobased PEF offers lower life-cycle greenhouse gas emissions than PET. However, with...

In relation to the development of environmentally-friendly processing technologies for the continuously growing market of plastics, enzymes play an important role as green and sustainable biocatalysts. The present study reports the use of heterogeneous immobilized biocatalysts in solvent-free systems for the synthesis of aliphatic oligoesters...

Endoglucanases are increasingly being touted as the ultimate solution for reducing energy consumption during the refining process in the pulp and paper industry. However, due to the high variety of endoglucanases in different enzyme formulations, these perform heterogeneously when applied to different pulps. In this study, the effect of four...
