Circular Economy

The mechanical recycling of multilayer laminated packaging films (MLPF) poses a considerable challenge due to the heterogeneity in plastic types and adhesives utilized. To address this challenge, this study uses two-step integrated chemolysis to upcycle MLPF. First, acids (acetic acids, formic acids, and succinic acids) were used to delaminate MLPF into separate layers that are made of polyethylene terephthalate (PET) and metalized polyethylene (PE/Al).

The Reconquista River, the second most polluted river in Argentina, accumulates large amounts of organic matter and persistent toxic pollutants in its sediments. These conditions drive the selection of microorganisms with the potential to degrade contaminants and facilitate bioremediation. Notably, these microorganisms form biofilms on clay minerals, enabling them to survive under extreme conditions and alter the properties of the sediments.

Scientific research increasingly demonstrates that chemicals and materials essential for everyday products threaten natural systems and human health. Transitioning to sustainable, circular, and low-carbon economies depends critically on having safer chemicals available. We propose that materials scientists should also account the impact of the health hazards of chemicals associated with the synthesis, processing, and manufacturing of materials.

CO2 electrolyzers have gained significant attention as a viable technology to convert CO2 to multi-carbon products, thus helping mitigate carbon emissions and promote carbon circularity.  To be competitive with current chemicals manufacturing, the selectivity of multi-carbon products and the process energy efficiency in CO2 electrolyzers needs yet to be improved. This work aims to address these challenges and make this reaction more sustainable by enhancing ethylene selectivity and improving reactor energy efficiency.
