Sustainable and organic plant production uses natural products and natural self-regulation processes occurring in the ecosystem. The awareness is growing and the demands of consumers are higher and higher. One solution is to use various methods, as an alternative to pesticides. It is also very important to care for the stored crops after harvesting especially using non-chemical methods. The physical method of plant protection consists in treating the harmful organism with physical factors such as temperature, its same light and radiation, controlled atmosphere, special packaging, pressure, various sounds, ozone, and low-temperature plasma. The availability of effective application techniques opens up new possibilities for the storage of crops in order to maintain their health and quality for a long time. This review focuses on the analysis of physical methods of postharvest protection, especially the latest methods using ozone and low-temperature plasma. As a result, consumers of agricultural crops will be able to consume food free of insects, mycotoxins and pesticide residues.

Analysis of methods of modification of polymeric textile materials to determine promising directions of obtaining new polymeric textile materials with specified properties. The analytical methods of researching the scientific problem of obtaining new polymeric textile materials with given properties of different types and methods of their chemical and physical modification are used in the article. Today, the main directions of updating and expanding the range of polymeric textile materials are not only obtaining new types of textile fibers and filaments, but their modification in various ways and methods. Therefore, the presented article analyzes the types of modification of polymeric textile materials and identifies promising ways of modifying them to obtain new materials with specified properties. One of the promising ways of modifying polymeric textile materials is the physical, and plasma technology of processing fibers and filaments. Of the plasma technologies and methods, the most effective is the method of application of low-temperature plasma, which allows without changing the chemical structure of the polymer fibers to achieve the predicted change in their properties. The analysis of the methods of modification of textile materials is carried out and the peculiarities of the change in their properties from the influence of various chemical and physical factors on them are determined. The main factors of influence of plasma technologies, changes in the structure and properties of polymeric textile fibrous materials are analyzed and the most promising of them are determined. It has been determined that the most effective, economical and environmentally friendly methods of physical modification of PTM polymers are electrophysical. Methods for the electrophysical modification of polymers of textile threads and fibers make it possible to provide their specific desired properties. Low-temperature plasma treatment of polymers does not affect their supramolecular structure and does not impair their other consumer properties; it can be carried out depending on the plasma parameters and the nature of the polymer fibers of the textile material.

Sterilization of municipal waste for a raw material for the production of refuse-derived fuel and to protect surface and ground waters against biological contamination during transfer and storage creates a lot of problems. This paper evaluates the antimicrobial potential of non-equilibrium plasma in relation to the selected groups of microorganisms found in humid waste. The proposed research is to determine whether mixed municipal waste used for the production of alternative fuels can be sterilized effectively using low-temperature plasma generated in a gliding arc discharge reactor in order to prevent water contamination and health risk for working staff. This work assesses whether plasma treatment of raw materials in several process variants effectively eliminates or reduces the number of selected groups of microorganisms living in mixed municipal waste. The presence of vegetative bacteria and endospores, mold fungi, actinobacteria Escherichia coli, and facultative pathogens, i.e., Staphylococcus spp., Salmonella spp., Shigella spp., Enterococcus faecalis and Clostridium perfringens in the tested material was microbiologically analyzed. It was found that the plasma treatment differently contributes to the elimination of various kinds of microorganisms in the analyzed raw materials. The effectiveness of sterilization depended mainly on the time of raw materials contact with low-temperature plasma. The results are very promising and require further research to optimize the proposed hygienization process.
