In this task, TUDelft investigates the principal feasibility of ligninases, specifically peroxygenases to oxidatively cleave the backbone of common thermoset composites. The chemical philosophy of this approach is based on the higher reactivity of C-H bonds next to heteroatoms such as O or N. The acetal-like structure of the resulting hydroxylation products is expected to [...]
BIZENTE: Flagship project at COMPOSIFORUM 2022 The Bizente project was one of the flagship projects presented at the 3rd edition of COMPOSIFORUM, the international forum on composite materials, organised by the Cátedra Aitiip-Unizar The Consortium members offered masterful speeches, approaching the project developments and industrial applicabilities to the audience, formed by a hundred of representatives [...]
Bizente gets to the last month of the year with promising developments. Polymers are an indispensable part of our modern life. The chemical structure of today’s polymers, however, also poses an enormous environmental challenge with our plastic wastes accumulating in the biosphere. The reason for this is that today’s polymers have been designed for durability, [...]
Within the framework of the M30 General Assembly, and hosted by the coordinator Aitiip Technology Center, Bizente's Consotrium also celebrated a stakeholders meeting, where a dozen of industrial representatives had the oportunity to meet Bizente's circular proposal. It was a working / technical session in which the Consortium led different technical presentations, to adress Bizente's [...]
Last November, Bizente celebrated its General Assembly at Aitiip's facilities, coinciding with the month 30 of the project lifetime. All the Consortium members were reunited with the aim of putting together the project progresses within each work package, and to discuss new strategies for the coming months. It was a really special meeting, since it [...]
The Bizente project was one of the flagship projects presented at the 3rd edition of COMPOSIFORUM, the international forum on composite materials, organised by the Aitiip-Unizar chair. The Consortium members offered masterful speeches, approaching the project developments and industrial applicabilities to the audience, formed by a hundred of representatives of companies related to multiple industries [...]
Busy month, November, for Bizente's Consortium. Our team is moving across Europe to show the project's developments and innovations. In this case, Aitiip and Biosphere scientists made a presentation of the project research lines at ESIB 2022. Within Bizente, we are applying ligninases to resolve end-of-life issues of thermoset composite plastics. In the end, [...]
As a first step for the toxicity & safety evaluation of products in BIZENTE project (WP3, Task 3.1), a toxicity test has been carried out by the University of Cadiz using Eisenia foetida. This organism is an essential earthworm in composting processes, as well as an indicator of healthy soil. The toxicity test has [...]
Aircraft decommissioning and recycling is a multi-disciplinary process, with environmental, operational, safety, legal and economic aspects. The number of aircraft retirements has been increasing steadily over the last decades. BIZENTE presents a biocatalytic model of enzymatic degradation as a novel alternative to the end-of-life (landfill and incineration) of thermoset composite. Tarmac Aragon has begun dismantling [...]
Bizente’s main goal is to develop enzymatic solutions for the end-of-life treatment of complex composite materials. EvoEnzyme is the partner in charge of the engineering of novel enzymes (ligninolytic and hydrolytic) by directed evolution to adapt them to the degradation process under industrial conditions (Fig 1.). Model scaffold molecules for four selected resins (Hexflow®RTM6, Araldine®LY1568, [...]
