A policy report highlights pathways for sustainable and circular aquaculture development in Germany and Brazil, emphasizing the potent yet underutilized freshwater aquaculture sectors. Separately, research from Chalmers University demonstrates how agricultural waste, specifically wheat straw and oat husks, can be converted into high-purity cellulose pulp for textiles, offering an eco-friendly alternative to cotton and wood fibers. These developments signify crucial steps toward sustainable resource use and bioeconomy growth, integrating environmental stewardship with economic opportunities.
