The current problem of the last decade in the world is the increase of oil production volume due to the extraction of its hard-to-recover reserves. The difficulty of its extraction is determined not only by the petro-physical characteristics of the oil-bearing formation, but also by the physico-chemical properties of the fluid itself. However, not all methods of enhancing oil recovery are ecologically safe. The most effective and ecologically-friendly method of soil purification from pollution by oil products is t...

The potential for biodegradation of chemically different dyes of six fungi and bacteria isolated from organic pollutants- and synthetic polymer-contaminated sites was determined. Standard enrichment isolation methods using low-nutrient-concentration media were used to obtain bacterial and fungal organisms from environmental samples. The isolates were taxonomically characterized using molecular analysis and Biolog identification system. The isolates included bacterial strains of Pseudomonas putida, Pseudomonas viri...

In a market where footwear quality involves both health improvement and a better environmental protection, ?environmentally-friendly footwear? that minimizes environmental and health impact, guaranteeing a certain level of quality, may fulfill the requirements of today's consumer. Throughout their life cycle, from leather processing to the finished footwear, resulting waste and chemicals contained in some of the products may be harmful for health and the environment. In accordance to European law, waste from the l...

Nowadays, the leading place in space industry production materials belongs to reinforced polymers. One of the most popular reinforced polymer in this sector is produced from aramid fibers and epoxy resin as matrix with hot solidification at temperature 160 ? 170 grad. Celsius. Despite the automated winding technology on modern machinery, there is an accumulation of epoxy resin as a waste happens. This paper is devoted to the processes of curing low-viscosity epoxy resin waste under the influence of orthophosphoric...
