A promising pathway toward this goal lies in leveraging of biopolymers derived from food waste, such as proteins polysaccharides, develop advanced Here, we design versatile hybrid materials by hybridizing amyloid nanofibrils self-assembly whey, dairy byproduct, with chitin exfoliated two distinct allomorphs α-chitin β-chitin, extracted seafood waste. Various hydrogels aerogels were developed via hybridization reassembly these biopolymeric nanobuilding blocks, they further magnetized upon biomineralization iron nanoparticles. The pH-phase diagram highlights significant role electrostatic interactions gel formation, between positively charged fibrils negatively nanofibrils. Hybrid magnetic exhibit ferromagnetic response characterized low coercivity (<50 Oe) high specific magnetization (>40 emu/g) at all temperatures, making them particularly suitable superparamagnetic applications. Additionally, transition, featuring higher blocking temperature (200 K) compared previously reported similar nanoparticles (160 K), indicating enhanced stability elevated temperatures. Finally, demonstrate practical application catalysts carbon monoxide oxidation, showcasing their potential environmental pollution control highlighting versatility catalyst supports.

Citrus fruits (CF) are among the most widely cultivated fruit crops throughout world and their production is constantly increasing along with consumers’ demand. Therefore, huge amounts of waste annually generated through CF processing, causing high costs for disposal, as well environmental human health damage, if inappropriately performed. According to recent indications an economic, pharmaceutical nature, processing residues must be transformed from a disposed valuable resource reused. Based on circular economy model, (i.e., seeds, exhausted peel, pressed pulp, secondary juice leaves) have increasingly been re-evaluated also obtain, but not limited to, compounds employed in food, packaging, cosmetic industries. However, use by-products still because underestimated nutritional economic value, hence more awareness knowledge needed overcome traditional approaches disposal.

High rates of resource consumption and waste generation have put pressure on environmental systems one the solutions to this concerning behavior is a circular bioeconomy (CBE). However, for CBE succeed, new businesses business models are needed, which many drawbacks might be faced. Therefore, article aimed (i) identify drivers, opportunities, challenges, barriers in both from theoretical practical perspectives, (ii) present regional differences those aspects different continents. A mixed-method approach was adopted, comprising systematic literature review semi-structured interviews with 32 organizations 18 countries 4 continents (Africa, America, Australia, Europe). Eight twenty as well fifteen drivers eight opportunities were identified. The main barrier challenge pointed out by stakeholders lack financial resources/capital, price competitiveness traditional/linear product offers. most prominent driver opportunity establishment public policies/governmental support, recovery. Regional CBEs (by continent) also Advancing requires setting strategies overcome developing and/or making adequate technology available locally, enabling traditional (linear non-renewable-based) options. This study unveils series managerial implications. There risk rebound effects, such becoming mainstream feedstock bioproducts being introduced market low-price strategies, thus triggering increased consumption. Premium pricing need considered bio-based products (compared non-bio-based products). Moreover, technological development plays role driving innovation, pioneers lead policies. For succeed there needs further greater connection among actors value chain, converging resilient CBE.

Intensive agriculture for food and feed production is a key driver of global biodiversity loss. It generally assumed that more extensive practices are needed to reconcile with conservation. In literature review across biomes seven taxa, we retrieved 35 alternative (e.g. no-tillage, cover crops, organic fertilizer) from 331 studies. We found no single practice enhanced all taxonomic groups, but overall less intensive agricultural beneficial biodiversity. Nevertheless, often had effects observed very rarely contrasting impacts on aboveground versus belowground taxa. Species responses were mostly consistent biomes, except fertilization. conclude enhance biodiversity, there also variation in depending group or type practice. This suggests careful selection secure taxa future systems worldwide.
