This article discusses the use of ash and slag waste such as ash or slag boilers and thermal power plants of Pavlodar region. We describe the main source of energy today. Produced by laboratory analysis of the composition of the ash. A basic installation for the processing of the ash. It presents the possibility of using fly ash in building materials industry.

Fruits and vegetables are most often consumed without being thoroughly processed before consumption. Some plant foods are vacuum-packed to ensure long shelf life as well as preserving the quality and safety of the product. Fruits and vegetables carry naturally occurring non-pathogenic epiphytic microflora on their surfaces. During growth, harvesting, transport and further handling they can be repeatedly contaminated by pathogens from human or animal sources. Fresh fruit crops have been implicated in a number of documented foodborne disease outbreaks. Outbreaks of diseases caused by bacteria, viruses and parasites have been epidemiologically linked to the consumption of a wide range of fruits and vegetables. The aim of our study is to assess the risk of contamination in fruit and berry crops and how to address this long-standing problem, namely, contamination of fruit and vegetables with unnatural pathogenic microflora. The following fruit and berry crops common in Turkestan region were chosen for the experiment: Apple variety Suislepskoe (stolovka) , peach variety Nectarine and grape variety Kishmish. Bacteriological inoculation was carried out by membrane filtration of used sterile water to obtain flushes from the surface of fruit crops. All work was carried out under full aseptic conditions. The utensils, water and other equipment used in the work were sterilised in advance. The data obtained during the experiment shows that there is a potential for widespread contamination of uncharacteristic microflora of plant products. Based on the results of the study it can be concluded that there are yeasts and acetic acid bacteria on the surface of all three samples of fruit and berry crops, which can be universally contaminated food and are not the natural microflora for the above mentioned crops. Specifically, fruits and vegetables can be contaminated with various bacterial pathogens, including Salmonella, Shigella, E. Coli O157:H7, Listeria monocytogenes and Campylobacter.

The development, grovth and productivity of livestock depend primarily on providing it with a variety of nutritious feeds. Daily feeds should consist of microbiologically synthesized protein, as well as a variety of seeds, mineral and vitamin supplements of animal and vegetable origin. Indeed, the maximum disclosure of the genetic potential of livestock largely depends on both the quantity and quality of feed. One of the stages of feed quality assessment is the measurement of their chemical composition. The chemical composition is not always constant and depends on many factors, including the species composition of plants, fertilizer application rates, climatic conditions and storage methods. The least accumulation of moisture in the soil was observed in areas where pasture grasses were regularly treated with wormwood. Pacture productivity was also the lowest in the control plots, where the average phyto-chemical composition over three years showed that the dynamics of protein content was the same in all pastures – the protein content reached a maximum at the beginning of the growing sea son and decreased from spring to autumn, while the lowest content of crude protein during harvesting in summer was in control plants of varieties
