Contribution of waste management to a sustainable textile sector.

With increasing textile consumption and limited sorting and recycling capacities, the EU faces major challenges in terms of managing its textile waste. This study investigates the environmental and socio-economic impacts of explorative policy scenarios for a more sustainable textile waste management system in Europe. These scenarios differ substantially in the amounts of textile waste generated and separately collected, closed-loop recycling capacities and textile waste exports. Our results show that sustainable textile waste management remains highly relevant for the sector. Still, without addressing in parallel prevention of textile waste generation via production and consumption patterns, a climate-neutral and circular textiles sector will be hard to achieve. Interventions in the waste management of textiles could reduce global warming impacts by up to 22.3 Mt CO2 per year, which translates to an 18% sector-wide impact by 2035. Depending on the intervention(s), the estimated required investment at present amounts to between 7 and 33 billion EUR. The study provides a valuable starting point for evidence-based decisions on future textile policymaking in Europe.

Biotoxicity and life cycle assessment of two commercial antifouling coatings in marine systems.

Two commercial coating systems, each one consisting of both a primer and an antifouling ("System 1" based on Copper Oxide and "System 2" based on Zinc Oxide), have been analyzed in order to investigate their environmental impacts through Life Cycle Assessment (LCA) and laboratory tests. A cradle-to-grave analysis has been performed in order to quantify the environmental footprint of each coating solution and to define which element, material, or process mainly affect the environmental impact of such products. Moreover, it was performed a comparison between the different products to determine the most environmentally sustainable choice. In addition to LCA, several incubations of coated metal samples, by means of an innovative incubation system developed by the authors, have also been performed in marine water (Gulf of Naples, Mediterranean Sea, Italy), as critical environment favoring metal corrosion and biofouling generation. The life cycle analysis has showed that the production phase presents the highest environmental impact in almost all categories, mainly due to the use of chemical compounds. Moreover, after the laboratory tests, strong biotoxicity and contaminant diffusion, contributing to the marine toxicity potential, have been observed for both the commercial paints. As a final remark, there are straightforward indications of a strong need for anti-Microbial-Induced-Corrosion commercial coatings to substitute the toxic compounds with others in order to develop a greener solution.
