The study examined how different levels of recycled polypropylene (PP) affect surface energy and how corona, e-beam, and low-pressure plasma treatments modify it. All treatments improved surface energy, with corona and argon plasma being most effective. Recyclate content strongly influenced results.
This study examined chitin and chitosan extracted from Tenebrio molitor (TM) at different life stages (larvae, adults, exuviae) for packaging applications. Exuviae provided the highest chitin and chitosan yields, while larvae-derived chitosan showed a slightly higher degree of deacetylation (DDA). These findings highlight the potential of using insect-derived chitosan — especially from exuviae — in sustainable packaging solutions.
Even though resource efficiency in automatic dishwashing has been in strong focus since the release of the eco-design directive, this 4-week ethnographic research study in 26 German households reveals, that real-life behavior in pre-cleaning, detergent use, program choice and appliance maintenance is still far from best practice: Manual pre-cleaning, mostly under running water, is a standard procedure. The ECO-program is still not within the top 3 programs used, even though cycle-time constraints prove not to be the limiting factor. Basic maintenance measures are frequently neglected and overdosing of special salt for regeneration and rinse aid is observed in ~50 % of the households using multi-function detergents. However, dishwasher load capacity is almost always fully used.
Ernährungskompetenz in Familien ist entscheidend, um ernährungsmitbedingte Erkrankungen zu vermeiden. Allerdings sind die Kompetenzen begrenzt, ebenso deren Transfer in den Familienalltag. Basierend auf der Analyse der Nutzung eines Rezeptbuches für Familien wird untersucht, welche Kompetenzbereiche im Alltag umgesetzt werden, und welche Ansätze geeignet sind, den Praxistransfer zu fördern. Internet und Kochbücher werden am häufigsten als Quellen für Rezepte und für den Kompetenzerwerb genutzt. Besonderes Interesse besteht in den Bereichen Speisenplanung, Zubereitung und Essverhalten. Kindliche Partizipation findet v. a. passiv im Zuge der Speisenplanung statt. Abendessen und Wochenend-Mahlzeiten bieten Potential, um aktive Partizipation und Kompetenzerwerb bei Kindern zu steigern.

Polymeric materials have emerged as pivotal components in textile finishing, offering a diverse array of applications to enhance the properties and functionalities of textiles. This review explores the multifaceted role of polymeric materials in textile finishing processes, delving into their significance in achieving desired attributes such as durability, comfort, aesthetics, and functionality. We started the exploration of various polymeric materials employed in textile finishing, encompassing polymers like silicones, fluoropolymers, polyurethanes, and beyond. The discussion unfolds the intrinsic properties of these polymers that contribute to their effectiveness in textile applications. The review extends to the techniques employed in applying polymeric finishes, encompassing methods such as padding, coating, and spray applications. The challenges associated with ensuring uniform application and durability are addressed, providing insights into optimizing these processes for enhanced performance. Furthermore, the environmental implications of polymeric finishes are discussed, with a focus on sustainable and eco-friendly practices. Innovations in developing biodegradable and recyclable polymeric finishes highlight the industry’s efforts toward mitigating environmental impact. The integration of polymeric materials in textile finishing represents a dynamic and evolving field. This review serves as a comprehensive guide for researchers, textile engineers, and industry professionals seeking to understand and harness the potential of polymeric materials in advancing the performance and sustainability of finished textiles.
Insects have emerged as a sustainable alternative protein source and recently gained regulatory approval in the European Union as novel foods and animal feed ingredients. However, the limited availability of species-specific proteomic databases presents a significant challenge for the accurate identification of proteins in insect-based food products, relevant for food authenticity, safety and allergenicity concerns. In this study, we developed a homology-based proteomic workflow to address the lack of comprehensive sequence data for edible insect species and to explore their allergenic potential. This nanoflow tandem mass spectrometry method (nano-HPLC HR-MS) aims to be generally applicable to underexplored species. We identified between 1079 and 1893 proteins for each of the six investigated insect species Acheta domesticus, Locusta migratoria, Tenebrio molitor, Alphitobius diaperinus, Gryllodes sigillatus and Hermetia illucens, increasing their numbers of known proteins up to 24-fold. Furthermore, we assessed the influence of error-tolerant peptide-spectra matching searches and database composition on protein identification and confirmed on average 90 % of selected peptides using targeted methods. We consistently detected known and putative allergens across all tested species, providing further evidence on their allergenic potential. Data from this study may provide the general basis for the development of targeted parallel reaction monitoring mass spectrometry-based assays for so far unsequenced species authentication and quantification of their proteins e.g. in novel foods. The data have been deposited to the ProteomeXchange with identifier PXD061237.
Die Verpackungsindustrie steht vor erheblichem Transformationsdruck: Zunahme und Verschärfung von Umweltauflagen, steigende Rohstoffpreise und wachsende Anforderungen an Nachhaltigkeit entlang der gesamten Wertschöpfungskette. Die KI bietet entscheidende Ansätze, um Materialkreisläufe effizienter zu gestalten, Ressourcen zu schonen und Prozesse zu optimieren. Dieser Artikel skizziert, wie KI die Transformation der Verpackungsindustrie hin zu einer nachhaltigeren, kreislauforientierten Bioökonomie gezielt beschleunigen kann und welche Chancen sich daraus für Unternehmen und Umwelt ergeben.
