There has been a significant rise in the adoption of biodegradable materials across industries. Industries including packaging, healthcare, and consumer goods need an accurate prediction of their degradation behavior to support environmental sustainability and ensure regulatory compliance. Here, we propose a deep learning-based framework that helps predict the decomposition rates and the associated environmental impact of biodegradable materials under diverse physicochemical conditions. We train the neural network on historical data of material performance, environmental exposure, and microbiological interaction, and the model shows its generalizability for life cycle estimation. The model has also been associated with an attention layer that monitors compliance with regulatory frameworks that govern material safety, quality, and consumer transparency. Standards and frameworks, including (ISO and ISI standards), are integrated into this layer to ensure adherence to product liability guidelines. Domain-specific regulations have been used to finetune the predictive outputs, keeping the permissible limits on product labeling, shelf life, and environmental claims. The approach shows better predictive results and demonstrates compliance with the legal context, and the model evaluation improves alignment with compliance thresholds and verification of the predictive results on the material life. Here, we explore a multidisciplinary approach that makes use of the learning abilities of ML algorithms and aligns the model performance with ethical frameworks to ensure trust and monitoring, creating intelligent systems for sustainable material design to improve sustainability and reusability, following regulations.

Food fraud has emerged as a significant and under-recognised public health threat, with documented global incidents resulting in severe illness, hospitalisations, and fatalities. International estimates suggest that up to 9% of the global food trade is adulterated. In South Africa, evidence of mislabelling, substitution, counterfeit products, illicit trade, and the use of unauthorised additives continues to surface, yet the national burden and regulatory response remain insufficiently characterised. This review synthesised peer-reviewed literature and articles from reputable South African media sources published from 2015 to December 2025, focusing on food fraud within the South African context. Searches were conducted across Web of Science (WoS), Scopus, and PubMed, supplemented by Google Scholar and the EU Food Fraud Database, with emphasis on studies reporting fraud associated with South African food products. Standard PRISMA procedures guided the final selection of fifteen (14) eligible articles. These studies reveal widespread food fraud driven mainly by economic gain. Common practices include substituting high-value products, mislabelling meat and seafood, altering dates on expired goods, and producing counterfeits with unauthorised additives and packaging. Collectively, these factors compromise consumer health, undermine industry integrity, and impede effective surveillance. Strengthening South Africa’s food fraud prevention ecosystem will require coordinated multisectoral engagement, targeted investment in detection technologies, and robust regulatory reforms.

Sustainability considerations increasingly influence food packaging design, with recyclability serving as a prominent, consumer-facing indicator of environmental responsibility. However, recyclable design alone does not ensure correct consumer disposal, particularly for materials requiring specialized recycling pathways. This study examined consumer disposal behavior for used Colby-Jack cheese stick packaging containing non-recyclable food-contact components and secondary packaging that was non-recyclable, recyclable, or conditionally recyclable, as indicated by the How2Recycle (H2R) labeling system for consumer packaged goods commonly used in the US and Canada. Using a controlled, in-person kitchen clean-up simulation, 105 adult participants disposed of three commercially representative packaging formats differing in material type (flexible plastic films and corrugated fiberboard) and recyclability. Participants were randomly assigned to one of three conditions: no recycling label, H2R label only, or H2R label plus brief educational instruction on label interpretation. Widely recyclable corrugated fiberboard trays were placed into the recycling bin significantly more often than all other packaging components (p < 0.0001), and the presence of an H2R label increased consumer recycling of this material relative to NoLabel (p = 0.0401), while additional education did not further improve outcomes. In contrast, attempts at consumer recycling store drop-off recyclable flexible plastic packaging increased significantly only when education accompanied labeling (p = 0.0038). Non-recyclable food-contact wrappers showed uniformly low recycling rates across all conditions. Wishcycling occurred among 18.9% of participants and was more frequent in the YesLabel group (p = 0.0433). These findings indicate that material familiarity strongly influences correct recycling behavior and that labeling alone may be insufficient for less familiar recyclable materials. Full article

Metal packaging materials remain fundamental across food, beverage, pharmaceutical, cosmetic, and technical sectors owing to their combination of mechanical robustness, total light and gas barrier performance, thermal resistance, and established recyclability. Aluminum alloys, tinplate, tin-free steel (TFS/ECCS), stainless steels, metal–matrix composites (MMCs), and metal–polymer or metal–paper laminates define distinct metal-based packaging architectures whose metallurgical and interfacial design governs forming behaviour, corrosion and migration pathways, coating integrity, and mechanical reliability. In this review, these architectures are examined from a materials- and systems-oriented perspective, linking composition, microstructure, processing routes, and surface engineering to functional performance across rigid, semi-rigid, and flexible formats. The analysis also considers the ongoing transition from bisphenol A (BPA)-based epoxy linings to BPA-free and hybrid coating chemistries, the use of nano-structured metallic and metal-oxide surfaces, and the role of composite laminates in which thin metallic foils are combined with polymeric or paper-based structural layers. These material and architectural aspects are discussed together with safety, regulatory, and circularity considerations that increasingly influence the design and selection of metal-based packaging. Ion migration, coating degradation, and corrosion under realistic storage environments are considered in relation to EU, FDA, ISO, and sector-specific requirements, while attention is also paid to the contrast between well-established closed-loop recycling infrastructures for aluminum and steel and the more complex end-of-life management of coated metals and multilayer laminates. The review provides a unified framework connecting materials selection, metallurgical design, processing, performance, regulatory compliance, and sustainability in metal-based packaging systems. Applications spanning consumer goods, pharmaceuticals, cosmetics, and advanced electronics are integrated to support an overall understanding of how metallic and hybrid metal-based architectures underpin functional reliability and life-cycle sustainability.

Microplastics (MPs) are pervasive environmental pollutants, widely distributed from aquatic ecosystems to the terrestrial food chain, and represent a potential route of human exposure. Although several reviews have addressed MP contamination, a critical synthesis focusing on pathways through which consumer goods directly enter food and beverages, along with corresponding industry and regulatory responses, is lacking. This review fills this gap by proposing the direct release of MPs from common sources such as food packaging, kitchen utensils, and household appliances, linking the release mechanisms to human health risks. The release mechanisms of MPs under thermal stress, mechanical abrasion, chemical leaching, and environmental factors, as well as a risk-driven framework for MP release, are summarized. Human exposure through ingestion is the predominant route, while inhalation and dermal contact are additional pathways. In vitro and animal studies have associated MP exposure to inflammatory responses and oxidative stress, neurotoxicity, and genomic instability as endpoints, though direct causal evidence in humans remains lacking, and extrapolation from model systems necessitates caution. This review revealed that dietary intake from kitchen sources is the primary pathway for MP exposure, higher than the inhalation pathway. Most importantly, this review critically sheds light on the initiatives that should be taken by industries with respect to global strategies and new policies to alleviate these challenges. However, while there has been an upsurge in research commenced in this area, there are still research gaps that need to be addressed to explore food matrices such as dairy products, meat, and wine in the context of the supply chain. In conclusion, we pointed out the challenges that limit this research with the aim of improving standardization; research approaches and a risk assessment framework to protect health; and the key differences between MP and nanoplastic (NP) detection, toxicity, and regulatory strategies, underscoring the need for size-resolved risk assessments.

Agricultural biomass has potential as a renewable and versatile carbon feedstock for developing eco-friendly and biodegradable polymers capable of replacing conventional petrochemical plastics. To address the growing environmental concerns associated with plastic waste and carbon emissions, lignocellulosic residues, edible crop by-products, and algal biomass were utilized as sustainable raw materials. These biomasses provided carbohydrate-, lipid-, and lignin-rich fractions that were deconstructed through optimised physical, chemical, and enzymatic pretreatments to yield fermentable intermediates, such as reducing sugars, organic acids, and fatty acids. The intermediates were subsequently converted through tailored microbial fermentation processes into biopolymer precursors, primarily polyhydroxyalkanoates (PHAs) and lactate-based monomers. The resulting monomers underwent polymerization via polycondensation and ring-opening reactions to produce high-performance biodegradable plastics with tunable structural and mechanical properties. Additionally, the direct extraction and modification of naturally occurring polymers, such as starch, cellulose, and lignin, were explored to develop blended and functionalized bioplastic formulations. Comparative evaluation revealed that these biomass-derived polymers possess favourable physical strength, thermal stability, and biodegradability under composting conditions. Life-cycle evaluation further indicated a significant reduction in greenhouse gas emissions and improved carbon recycling compared to fossil-derived counterparts. The study demonstrates that integrating agricultural residues into bioplastic production not only enhances waste valorization and rural bioeconomy but also supports sustainable material innovation for packaging, farming, and consumer goods industries. These findings position agriculture-based biodegradable polymers as a critical component of circular bioeconomy strategies, contributing to reduced plastic pollution and improved environmental sustainability.

Immersive methods and biometric tools provide a rigorous, context-rich way to study how people perceive and choose food. Immersive methods use extended reality, including virtual, augmented, mixed, and augmented virtual environments, to recreate settings such as homes, shops, and restaurants. They increase participants’ sense of presence and the ecological validity (realism of conditions) of experiments, while still tightly controlling sensory and social cues like lighting, sound, and surroundings. Biometric tools record objective signals linked to attention, emotion, and cognitive load via sensors such as eye-tracking, galvanic skin response (GSR), heart rate (and variability), facial electromyography, electroencephalography, and functional near-infrared spectroscopy. Researchers align stimuli presentation, gaze, and physiology on a common temporal reference and link these data to outcomes like liking, choice, or willingness-to-buy. This approach reveals implicit responses that self-reports may miss, clarifies how changes in context shift perception, and improves predictive power. It enables faster, lower-risk product and packaging development, better-informed labeling and retail design, and more targeted nutrition and health communication. Good practices emphasize careful system calibration, adequate statistical power, participant comfort and safety, robust data protection, and transparent analysis. In food science and consumer behavior, combining immersive environments with biometrics yields valid, reproducible evidence about what captures attention, creates value, and drives food choice.

Background/objectives: Antimicrobial resistance (AMR) is a growing public health concern, and misuse of antibiotics in livestock farming contributes to its emergence. In Blantyre, Malawi, small-scale pig and poultry farming is widespread, but the knowledge, attitudes, and practices (KAP) driving antimicrobial use (AMU) remain poorly understood. This study aimed to assess the KAP regarding AMU and manure management among pig and poultry farmers in Blantyre, Malawi. Methods: This cross-sectional study surveyed 118 randomly selected farmers to assess AMU patterns, sources of antibiotics, adherence to withdrawal periods, disposal practices, and awareness of AMR and regulations. Data was collected using a structured questionnaire and analyzed with descriptive statistics and inferential tests (with statistical significance set at p < 0.05). Results: Antibiotic use was reported by 88% of farmers, primarily for therapy (93.3%) and prophylaxis (85.6%), including for viral diseases such as Newcastle disease in poultry and African swine fever in pigs. Oxytetracycline (91.5%), penicillin (50.8%), and trimethoprim-sulfamethoxazole (39.8%) were the most used antibiotics, predominantly sourced from agrovet shops (73.7%). While 61% of farmers knew antibiotic misuse could lead to AMR, significant gaps were observed: 68.6% had no formal training, 55.9% were unaware of regulations, and 42% sold/consumed products before the end of the withdrawal period. Most farmers disposed of expired antibiotics (80.5%) and packaging (92.4%) in household waste. Higher education and prior training were significantly associated with good knowledge. Conclusions: This study reveals significant knowledge–practice gaps and high-risk behaviors, such as misuse for viral diseases and unsafe disposal, that exacerbate AMR risks. Interventions must prioritize targeted farmer education, strengthening of veterinary extension services, and stricter regulation of agrovet shops to promote antimicrobial stewardship and support Malawi’s National Action Plan on AMR.

This paper presents a hybrid fabrication method for producing anti-counterfeit optical elements on plastic products and surfaces targeting multidiscipline applications such as food, pharmaceuticals, luxury goods, and electronics industry. Our proposition combines the design flexibility and rapid prototyping capabilities of stereolithography three-dimensional (SLA 3D) printing with nanoimprint lithography (NIL) to create unique optical security tags onto plastic surfaces. The proposed approach is cost-effective, scalable, and tailored for mass production, addressing the increasing demand for secure and reliable authentication solutions. NIL is substrate agnostic, offering material selection versatility and realization of security tags onto polymer surfaces, which are widely used across various sectors such as packaging industry, medical devices, and flexible electronics. This enables integration into a wide range of materials, further enhancing applicability on flat and 3D shape surfaces. An evaluation method based on digital reconstruction has been used to ensure robust performance and verification of the produced optical security features. The results demonstrate that this hybrid approach provides a reproducible and technically feasible path for the development of optical anti-counterfeiting tags suitable for large-scale implementation, particularly within fast-moving consumer goods (FMCG).

There is pressure on security operations centers (SOCs) from public and private industries as they are coping with the surge of cyberattacks, which is making the reconciliation of inherent organizational tensions a priority. This study surfaces two persistent tensions: (1) expediency versus authority, and (2) adaptability versus consistency that have remained underexplored in cybersecurity literature. We based the research on empirical data collected across three organizational settings, an international consumer packaged goods, a non-departmental public body based in the Netherlands, and a global managed security service provider. Thus, we reveal these not as isolated trade-offs but as paradoxes that must be continuously navigated within SOC operations. Built upon both empirical analysis and Paradox Theory, we develop a conceptual model that explains how SOCs reconcile these tensions through the strategic integration of artificial intelligence (AI), automation, and human expertise. Our model emphases that AI and automation do not replace human analysts; rather, they allow a new form of organizational balance, through mechanisms such as Dynamic Equilibrium and iterative integration. The model demonstrates how SOCs embed technological and human capabilities to sustain simultaneously agility, consistency, authority, and speed. By reframing AI integration as a process of paradox reconciliation, not as a resistance or automation alone, this study contributes new theoretical insight into the sociotechnical dynamics shaping the future of cybersecurity operations.

There is increasing awareness about the adverse environmental and ‘food’ animal welfare impacts associated with the production of meat-based pet food. However, little is known about cat guardians’ acceptance of more sustainable food choices for the global population of approximately 476 million pet cats. By surveying 1380 cat guardians, this study explored feeding patterns used by guardians, determinants of their cat food choices, and their acceptance levels of more sustainable cat food alternatives. The sources of information used by cat guardians to obtain information about the cat diets they chose were also investigated. Key results included: (1) 51% (620/1211) of cat guardians currently feeding meat-based cat food (raw or conventional) considered at least one or more sustainable alternatives to be acceptable, with cultivated meat-based cat food being the most popular alternative, followed by nutritionally sound vegan cat food; (2) the top five characteristics alternative diets needed to offer to be considered viable were good health outcomes, nutritional soundness, palatability, quality, and environmental sustainability; (3) diet types consumed by cat guardians and their cats were strongly associated; and (4) labels/packaging and veterinarians were the information sources most used, although veterinary staff may have been less trusted as reliable sources of dietary advice by guardians feeding unconventional diets. It should be noted that, due to the reliance on convenience sampling and the overrepresentation of respondents from the UK, of female guardians, of respondents with higher education and of vegan guardians, the reported relative frequencies of subgroups were not fully representative of the global cat guardian population. Association estimates were based on regression analyses to minimize any resultant bias effects. Full article

The application of lattices as protective materials/structures is rapidly increasing. This requires improving impact absorption capabilities to protect goods in packaging and prevent human injuries in protective devices. This study aims to improve the accuracy of impact and energy absorption measurements for lattices, addressing the limitations of current methods such as energy-impact diagrams and instrumented drop-impact testers. A novel test setup is introduced by utilizing a modified Charpy test machine equipped with appropriate instrumentation to directly measure both energy and acceleration. Other modifications include adjustments to the machine components and the introduction of a new sandwich configuration for the test specimen, ensuring compatibility with the machine’s geometry and the test objectives. The attractiveness of the proposed test setup lies in its simplicity and efficiency. Unlike drop-impact test machines—which require complex, time-consuming, and error-prone data integration and derivation—the proposed method eliminates the need for postprocessing, as both energy and impact are recorded directly and instantaneously by the machine. The advantage over existing setups becomes particularly evident when considering that, in the presence of noise and high-frequency fluctuations—characteristic of sensor data from impact events—errors in numerical operations can range from 30% to over 100%. The functionality of the proposed test setup is evaluated through a series of experiments, and the results are compared with those obtained from existing methods. Our findings demonstrate the effectiveness of the new setup in providing accurate and direct measures of absorption parameters, offering a significant improvement over the traditional approaches.

The outlook for biobased plastics in packaging applications is increasingly promising, driven by a combination of environmental advantages, technological innovation, and shifting market dynamics. Derived from renewable biological resources, these materials offer compelling benefits over conventional fossil-based plastics. They can substantially reduce greenhouse gas emissions, are often recyclable or biodegradable, and, in some cases, require less energy to produce. These characteristics position biobased plastics as a key solution to urgent environmental challenges, particularly those related to climate change and resource scarcity. Biobased plastics also demonstrate remarkable versatility. Their applications range from high-performance barrier layers in multilayer packaging to thermoformed containers, textile fibers, and lightweight plastic bags. Notably, all major fossil-based packaging applications can be substituted with biobased alternatives. This adaptability enhances their commercial viability across diverse sectors, including food and beverage, pharmaceutical, cosmetics, agriculture, textiles, and consumer goods. Several factors are accelerating growth in this sector. These include the increasing urgency of climate action, the innovation potential of biobased materials, and expanding government support through funding and regulatory initiatives. At the same time, consumer demand is shifting toward sustainable products, and companies are aligning their strategies with environmental, social, and governance (ESG) goals—further boosting market momentum. However, significant challenges remain. High production costs, limited economies of scale, and the capital-intensive nature of scaling biobased processes present economic hurdles. The absence of harmonized policies and standards across regions, along with underdeveloped end-of-life infrastructure, impedes effective waste management and recycling. Additionally, consumer confusion around the disposal of biobased plastics—particularly those labeled as biodegradable or compostable—can lead to contamination in recycling streams. Overcoming these barriers will require a coordinated, multifaceted approach. Key actions include investing in infrastructure, advancing technological innovation, supporting research and development, and establishing clear, consistent regulatory frameworks. Public procurement policies, eco-labeling schemes, and incentives for low-carbon products can also play a pivotal role in accelerating adoption. With the right support mechanisms in place, biobased plastics have the potential to become a cornerstone of a sustainable, circular economy. Full article
