This article discusses some of the problems of chemical safety, such as the recycling of waste production, chemical accidents and disasters, environmental pollution and the negative effect of the chemical industry on human health, as well as methods for safer handling of chemical products.

In this article issues of efficient use of ferroalloys production waste to save costs are considered; energy efficiency of agglomerate production is calculated; sintering heat balance data are presented by a case study of Aksu Ferrolloy Plant. According to the annual economic benefits calculation the folowing results are obtained: due to аglogases recirculation, fuel saving is 1334.5 t.o.e.; due to reheating it is 1491 t.o.e.; due to installation of thyristor converters to the unit the annual energy saving is 1714000 kWh. Thus, it is identified that besides energy-efficiency measures during recycling of solid and gaseous wastes, the use of agglomerate increases IPF electric furnaces performance as well, decreases specific energy and reducing agent consumption which means the prime cost of finished products will be reduced.

This article is devoted to the consideration of methods for receiving copper powder. The main methods of obtaining copper based on them are analyzed, the possibility of complex extraction of the investigated metal from spent solutions (wastes) of electrolytic production of copper.

In Kazakhstan, within the framework of the Program «Development of domestic value and export-oriented industries», new modern dairy enterprises are being actively modernized and new modern dairy enterprises are being created, where membrane processes are being introduced to concentrate the components of milk. This is necessary for the rational and integrated use of raw materials, including through the processing of secondary resources, the main of which is whey. Improving the production processes of traditional food products and developing innovative ones is possible only with the use of the latest technologies and technological equipment. Membrane processes are widely used for the use of fractionation and concentration of liquid dairy products, which allows for a new solution to the processing of raw materials and opens up opportunities in the development of new types of food products. The article is devoted to the issue of production and processing of whey in Kazakhstan. The main types of membrane technologies and the advantages of their use in the dairy industry in the Republic of Kazakhstan are considered. The role of membrane technologies in the processing of whey is substantiated, various methods of introducing membrane processing methods to ensure the demineralization of whey, obtaining products with high biological value and consumer properties, reducing the cost of energy carriers, reducing the volume of raw materials in order to save transport costs, non-waste processing of milk solids, recycling water are described. This article analyzes the problems of using resource-saving membrane technologies in the production of dairy products in the Republic of Kazakhstan, ways to solve existing problems associated with increasing the economic efficiency of enterprises. The favorable impact of the use of membrane technologies on the social and environmental aspects of whey processing in the country is substantiated.

The relevance of this article is that the impact of human economic activity on the natural environment is becoming comparable in scale to geological factors. In this regard, the importance of protecting the biosphere has increased immeasurably. The earth is the only common home of all earthlings. Society, including us, cannot help but worry that the planet has approached a critical ecological threshold. The main goal of the research that we set for ourselves in this article is to create a predictive model for overcoming the environmental crisis in the following areas: environmental education, greening technologies, administrative and legal direction, international cooperation. To achieve the result, we tried to process as much information as possible, analyze the situation, draw appropriate conclusions and propose our own model for overcoming the environmental crisis. The hypothesis is that environmental pollution, improper disposal of household and industrial waste, and poor environmental culture have a detrimental effect on the ecology of the city, poisoning the environment and public health. The main research methods used were methods of empirical knowledge - these are observations, survey methods, questionnaires, as well as theoretical methods. The results of these studies can be used to inform the population about the impact of waste on human health, as well as the importance of storing, recycling and obtaining secondary raw materials, in order to reduce the amount of garbage on city streets. And also about the existence of unauthorized waste collection sites and administrative responsibility for the creation of such landfills in the city and in the surrounding area, this is an educational activity in all areas of education, starting from preschool institutions, the media, advertising agencies, NGOs, environmental authorities and also, using international experience, in the construction of a solid waste processing plant in his hometown.
