Marine biomass including fishery products are precious protein resources for human foods and are an alternative to livestock animals in order to reduce the virtual water problem. However, a large amount of marine waste can be generated from fishery products and it is not currently recycled. We evaluated the metabolism of digested marine waste using integrated analytical methods, under anaerobic conditions and the fertilization of abandoned agricultural soils. Dynamics of fish waste digestion revealed that samples of meat and bony parts had similar dynamics under anaerobic conditions in spite of large chemical variations in input marine wastes. Abandoned agricultural soils fertilized with fish waste accumulated some amino acids derived from fish waste, and accumulation of l-arginine and l-glutamine were higher in plant seedlings. Therefore, we have proposed an analytical method to visualize metabolic dynamics for recycling of fishery waste processes.

Scent marking through urine spraying is known to aid mate selection, territory marking and chemical communication in terrestrial, but not in aquatic mammals. We quantify an unusual aerial urination behaviour in botos (Inia geoffrensis) and discuss its potential functions. Between 2014 and 2018, we conducted land-based behavioural surveys on wild botos in central Brazil, recording the sequence, duration and social context of aerial urination.

A vast sum of fish waste is being annually discarded by marine fishing industries imposing serious environmental pollution concerns. However, these aquatic discarded matters are captivating sources of collagen, a fibrous protein with eminent social and economic relevance. Collagen is conventionally recovered using outdated complex processes requiring many reagents, multiple steps, and extended periods.

: An emerging practice within the concept of circular beauty involves the upcycling of agro-industrial by-products. Cork processing, for instance, yields by-products like cork powder, which presents an opportunity to create value-added cosmetic ingredients. Building upon our previous research, demonstrating the antioxidant potential of hydroalcoholic extracts derived from two distinct cork powders (P0 and P1), in this work, aqueous extracts were prepared and analyzed.

The production of plastics and associated products, including microplastics (MPs), has been surging over the past several decades and now poses a grave environmental threat. This is because when not appropriately recycled, incinerated, or disposed of in fully contained landfills, plastic waste manifests as a potent pollutant, with vast amounts finding their way into oceans annually, adversely impacting marine life and ecosystems. Additionally, research also confirms there are direct impacts from MPs on water, air, and soil, impacting ecosystem and human health.

Avoiding food waste has become an important global issue. Given the global impact of food waste and the profound influence of Generation Z on future development, it is crucial to guide them in cultivating awareness and behaviors to reduce food waste, thereby promoting sustainable development. Considering young consumers' specific characteristics and consumption environment, this study extended the Theory of Planned Behavior (TPB) framework by adding two constructs of moral self-identity and scarcity mindset.
