In studies on ash and slag waste processing at Magadan TPP an important part is primary processing with simple metal recovery. Gravity enrichment methods in this case are well suited for primary processing. The main expected metal extraction in this case is magnetite in the main mass of the concentrate. Extraction of magnetite will achieve the first objective of the recycling study - to achieve 10% recycling of ash and slag waste.

In this article, the authors assess the problem of annual increase in ash and slag waste produced by Russian thermal power plants.

The option of upgrading a container for storing and transporting spent nuclear fuel was considered. The container is characterized in that the channels for accommodating neutron protection are decorated with metal pipes. Between the side surfaces of the metal pipes are installed inserts of neutron-protective material.

Garbage and various waste products are an integral part of human life, but today they have become a global problem. The main reason why the accumulation of garbage requires special attention and new ways of processing and disposal is the accumulation of hazardous waste generated by the population. The article deals with the problems of waste management of 1st and 2nd hazard classes, the ways of solving these problems are proposed. The main purpose of this article is to determine the authorities responsible for hazardous waste management, review the hierarchy of waste management in case of hazardous waste. As a result, recommendations for establishing a system of separate collection and utilization of hazardous waste are proposed.

In the article the methods of using lean production tools for elimination of each kind of waste are considered. The reasons of waste occurrence and consequences to which they lead are determined. Recommendations for elimination of waste for garment production are suggested.

In the framework of the basic operations of the timber industry, an important place is occupied by cutting operations of sawing raw materials. When cutting sawing raw materials into sawn materials, losses and the transformation of a certain part of raw materials into waste are inevitable. When supplying abroad, the need for a scientifically based classification of raw material and its waste is becoming more acute.

An overview of inventions and patents for utility models patented in 2010-2018 in Russia for the harvesting of logging residues on cutting areas.

On the territory of the Krasnoyarsk Territory, the problem of utilization of wood waste is one of the most urgent, since at present almost half of the biomass of a tree is lost during processing, which naturally indicates a low level of technological processes of wood processing.

The article deals with the ecological problems of the Pavlodar-Irtysh Priirtyshye. For a long time, it was believed that the Pavlodar region in terms of pollution is not a problem region. Recently, ecologists of the region have been alarmed by the fact that in the short period, since the 1990s, the region has become a leader in the level of air pollution. Today, in terms of pollution level, the Pavlodar region takes the third place in the republic. One of the causes of pollution of the environment is the rapid development of industry. As a part of ecological support, our students, like many other residents of the Pavlodar region, are involved in cleaning up their native city and the Irtysh floodplain, as a favorable habitat is an important part of life and health of people.

There is a wide range of possibilities for using wood waste in industry: the production of gasified fuel, the production of methanol, sorbents, lignin, heat-insulating materials, wood flour, cellulose, essential oil, arbolite, composite plywood, activated carbons, coniferous extracts, energy chips, etc.

On the territory of the Krasnoyarsk Territory, the problem of utilization of wood waste is one of the most urgent, since at present almost half of the biomass of a tree is lost during processing, which naturally indicates a low level of technological processes of wood processing.

In the second half of the twentieth century logging wastes were considered as a serious resource of raw materials for industrial use. This led to serious research for logging residues.

In PetrSU, the solution of the problem of involving logging waste is used in the search and dissertational research, including the study of energy wood resources, the patent search for promising solutions for integrated harvesting of business and fuel wood, the rationale and patenting of such solutions.

A method for manufacturing a container for transporting and storing nuclear fuel wastes is described. Provides weight reduction, simplification of machining, reduces the likelihood of occurrence of foundry defects.

The need to use organizational and technological innovations for involving wood waste in bioenergy is shown. Some areas of research on the use of innovations in bioenergy are presented.

We analyzed some of the results of intensive research experts of Petrozavodsk State University in the field of intensification of harvesting of commercial timber harvesting with the recycling of waste.

The article carries out an analytical review of different approaches to defining the “green economy” phenomenon. The main fields and ways of using this term are described. The existing environmental management tools (environmental impact assessment, certification, auditing and the best available techniques) do not allow to evaluate environmental compatibility of projects and technologies, and are not able to specify the ways of their optimization. The authors suggest estimates of non-wastes, specific consumption, ecological and economical effectiveness, land capacity. The efficiency of reducing their values to a single integral component was proved in the article.

В данной статье раскрыта позиция авторов в отношении причин образования несанкционированных свалок на примере г. Волжского Волгоградской области. Приведены результаты исследований прилегающей территории, а также предложен метод оптимального размещения контейнерных площадок для новых микрорайонов.

Важной проблемой современного природопользования является защита окружающей среды от негативного воздействия со стороны промышленных предприятий. В статье раскрывается метод очистки сточных вод предприятий ЦБП от трудноокисляемых лигнинных соединений с помощью коагулянтов и флокулянтов. Автором определены наиболее значимые физико-химические характеристики сточной воды, показывающие эффективность использования флокулянтов. Сделан вывод о необходимости применения определённого типа флокулянтов для повышения эффективности коагуляционной очистки сточных вод ЦБП.

In this article, the issues of wastewater treatment and sanitary conditions for draining. Sewage is the water that was used for various needs and received additional impurities, which changed their original chemical composition and physical properties.
