Sintesi del contesto e degli obiettivi generali del progetto

The universal use of different types of plastic-based materials as new products to meet the insatiable global demands of the 20th century has had an unprecedented impact on our evolution as a society. Unfortunately, micro- and nano-plastics are now ubiquitous in marine and freshwater environments, as well as terrestrial ecosystems, where they act as a source of highly detrimental toxic chemicals that negatively affect the environment and human health by interacting with terrestrial organisms that mediate ecosystem services and functions, such as soil dwelling invertebrates, terrestrial fungi and plant pollinators. It is our duty as scientists to provide immediate and appropriate solutions to reduce the detrimental effects of micro-/nano-plastics on our planet. To this end, the BMRex consortium is working on development of entirely new concept for micro-/nano-plastic contaminant removal from household and industrial wastewater effluents by validating a novel biocatalyst-based membrane reactor technology to capture and degrade plastic waste. The consortium will produce, test, and optimize innovative biocatalytic membrane reactors based on porous inorganic scaffolds functionalized with biocatalysts. BMRex will also evaluate the economic, technological, and environmental viability of this novel technology. With its unique integration of scientific approaches, competences, and resources, BMRex has the potential to open an entirely new heterogeneous catalysis field. In the long term, this project aims to enable a more efficient and safer recycling of wastewaters by trapping and degrading micro-/nano-plastics in situ, with the grand aim of initiating transformative effects on our society, which is currently in the early phases of transitioning toward a more environmentally sustainable use of plastic.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

During the first year of BMRex project, numerous activities have been carried out to achieve the proposed objectives. Laboratory experiments were initiated to identify novel enzyme candidates for plastic degradation, addressing the objective on screening and discovery of new biocatalysts. Bioassays for monitoring microbial growth and bioactivity related to plastic degradation were carefully evaluated and selected. Additionally, known plastic-degrading enzymes have been successfully produced and delivered to BMRex partners for use as standards in bioassays. A variety of inorganic materials were successfully synthesized, processed, and deployed for manufacturing the BMRex reactor. In addition, the surface-active antimicrobial activity of inorganic component was studied to select the most active variants for preventing biofilm formation and thus avoid potential biofouling of the BMRex reactor.
As part of BMRex reactor inorganic component manufacturing activities, a numerical simulation of inorganic scaffold structures was performed to enhance the preparation of a highly robust inorganic scaffold structures with hierarchical porosity features and high micro-/nano-plastics (MNPs) accumulation functionalities. Initial preliminary results have shown promising results in accordance with the proposed hypothesis of the BMRex project, creating an optimistic perspective for the future of the project.

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

BMRex consortium is manufacturing and validating a first-of-its-kind procedure for the elimination of micro-/nano-plastics from the water cycle through their capture and enzymatic degradation, delivering a sustainable and environmentally friendly solution. The innovative approach is targeting the direct release of micro- nanoplastics from industrial and household wate water treatment plants or even their accumulation within generated sludge. Apart from direct environmental impact on wastewater quality, the later one will open the possibility to reuse decontaminated sludge, providing new market opportunities. The technological potential of the BMRex concept at different scales and in a variety of allocations opens a potential worldwide market under these scenarios. Nevertheless, due to the early phase of the BMRex project, the technology under development has not yet resulted in any accountable economic impacts. Moreover, the envisaged technology could not only be extrapolated to combat other critical contaminants (such as heavy metals, disinfectants, pharmaceuticals or other hormonally active chemicals), but also potentially impact on energy-related applications (catalysts, flue gas purification, etc.) and sustainable biomanufacturing (pharma and food industries).
On the other hand, during the first year of activity the BMRex consortium has hired several young researchers and actively performed communication and dissemination activities targeting scientific community and the general public. This includes conference presentations, lectures, public talks, participation in TV and radio programs and etc.
