The scientific community has placed increasing importance on sustainability, leading to the exploration of alternative bedding materials widely used aspen wood chips. Bedding plays a critical role in ensuring wellbeing animals and validity experimental outcomes. Compared frequently evaluated biological materials, such as corncobs or spelts, synthetic plastic granules have been less investigated. We characterized two thermostable an material C57BL/6J BALB/c mice. examined impact those alternatives physiological parameters, behavior, health status, cage climate static digitally ventilated cages well possibility reuse cycle after reprocessing. mouse lines showed different locomotor activity, feeding, nestbuilding behavior granules. While ammonia levels were constantly higher than cages, blood parameters unaltered, status was maintained during procedure. show use granulate for mice that potential processing recycling. Further, we is accepted differently by preference choice test without affecting their hygiene status.

Reductive Upcycling of Polyolefins, Polyesters and Mixed Plastic Wastes to Valuable Chemicals: Bridging Chemical Catalysis With Plastic Waste Management

Advanced Sustainable Systems, Год журнала: 2025, Номер unknown

Опубликована: Март 20, 2025

Abstract The unmatched applications of plastic commodities are evident from the enormous production, reaching over 400 million tons per year in recent times. Contrastingly, lack proper management leads to a large accumulation waste, majorly including polyolefins and polyesters. Conventional methods possess significant drawbacks like cost‐ineffectiveness greenhouse gas emissions. Over last decade, chemical processes have shown promising potential for but only hold 0.1% share recycling. catalytic offer excellent protocols obtain high‐value liquid fuels, waxes, chemicals waste. This review presents an elaborate discussion on state art reductive upcycling polyolefins, polyesters, mixed initially discusses alarming statistics plastics conventional approaches followed by introduction processes. Further, various recently reported strategies been elaborated detail catalyst deactivation, technoeconomic analysis, life cycle assessment deeper understanding current this research field. Finally, detailed summary along with existing challenges countermeasures is discussed open new avenues waste research.

Chemical Interaction Between Starch‐Polyvinyl Alcohol Matrix With Barley Microfibers: Structural, Barrier, and Viscoelastic Performance in Extruded Films

Biopolymers, Год журнала: 2025, Номер 116(4)

Опубликована: Май 30, 2025

ABSTRACT In this study, the effect of microwave (MW) treatment on obtaining barley microfibers and their chemical, structural, viscoelastic properties films based starch (S) polyvinyl alcohol (P) was inspected. SEM, FTIR, TGA analysis revealed that MW effectively achieves defibrillation destabilization hydrogen bonds hemicellulose lignin molecules, resulting in obtention (BM). XPS allowed identification oxidation crosslinking mechanism S, P, S/P containing BM during extrusion process. PBM SPBM showed an increase CC proportions linked to phenomena promoted stronger OCO interactions, which increased storage modulus from 195.5 380.8 MPa 78.0 134 MPa, respectively. Conversely, SBM lower interactions high COH reduced component adhesion. Thus, matrix type process determined chemical interaction with BM, different rigidity can be useful sustainable packaging solutions.

Polyvinyl chloride applications along with methods for managing its end-of-life items: A review

Progress in Rubber Plastics and Recycling Technology, Год журнала: 2024, Номер unknown

Опубликована: Дек. 13, 2024

Owing to its unique blend of properties, polyvinyl chloride (PVC) has become one the most important polymers that have been used in everyday life for many years. Its short- and long-term applications span multiple key industries such as building, electrical/electronic insulation, packaging, healthcare. These produce high volumes PVC solid items require responsible management when they reach their end-of-life because are not biodegradable. Simple affordable methods diverting this waste from landfills would contribute positively towards combating environmental problems. However, approaches reported literature there is a need collate easier comparison. For example, some alternative highly effective transforming into range valuable products but still associated with secondary pollution. This overview covers different facets virgin (rigid, semi-rigid, flexible), focusing mainly on importance, global increase use, waste’s recyclability. In addition pros cons recycling strategies, influence specific factors expanding market also considered albeit briefly. Notably, [Formula: see text]50 % world’s annual production utilization capacity accounted by meant building applications; these drive growth market.
