Plastic pollution has been identified as one of the most pressing environmental issues of the 21st century, driven by excessive consumption and inadequate plastic waste management. This issue is particularly reflected in short lifespan of plastic products, particularly plastic packaging within the food and beverage (F&B) industry. Urgent and relevant policy actions are needed to promote plastic circularity and improve waste management practices.

Two lytic phages, LASTA and SJM3, active against several pandrug-resistant, nosocomial strains of were isolated and characterized. Their host range is narrow and latent period is particularly long; however, their lysogenic nature was refuted using both bioinformatic and experimental approaches.

Ultra-high performance liquid chromatography coupled to diode array detection and mass spectrometry (UHPLC-DAD MS/MS) analysis confirmed the abundant presence of phenolic acids and flavan-3-ols in the grape-pomace-seed extract (SE) and heat-treated skim goat-milk/seed-extract powder (TME). After in vitro digestion of TME powder and recovery of total quantified phenolics, flavan-3-ols and phenolic acids were 18.

This work aimed to examine the influence of simulated digestion in the presence of complex food matrix on antioxidant and cytotoxic activity of red wine. The obtained results showed that total phenolic content of wine sample after digestion was higher compared to undigested wine, while the antioxidant activity of these samples was similar before and after digestion.

Additionally, mushrooms are known to possess pronounced capacity for absorption of various micronutrients, including Se, from soil/substrate. Here, we investigate the possibility of using Se-rich zeolitic tuff as a supplement for production of selenized mushroom.

Deficiencies are often present for adequate procedures for the management of asbestos waste; solid quality data or databases on the quantities of asbestos production and usage are missing and asbestos inventories or the registry of asbestos-related diseases following European Union (EU) or other regulations are not in place. This paper aims to develop a model for determining and assessing the quantity of asbestos in the built environment of a transition country.

In order to assess the effectiveness of the implementation of separate collection systems for plastic packaging, especially polyethylene terephthalate (PET) bottles, characteristic of the collected PET bottles in street mesh containers were studied in the city of Perm, Russia. The share of extraneous fractions was assessed and differentiation was carried out by volume, type of product, label presence, shape, content of solid and liquid impurities and colour.
