The article touches upon the problem of waste disposal in the territory of the Russian Federation. The foreign experience of construction of utilitarian enterprises, existing technologies for waste recycling is given. Special attention is paid to the creation of an attractive architectural and artistic image of a modern industrial enterprise through the use of modern three-dimensional, constructive solutions in the implementation of architectural plans, ensuring the attractiveness of objects for the population by ensuring their multifunctionality.

This article discusses the importance of timely monitoring of the technical condition of structures and buildings in general in the process of preserving cultural heritage objects. And also, using the example of the Rostov region, the article raises one of the existing organizational and technical problems of preserving cultural heritage objects – the lack of the ability to conduct timely monitoring of the technical condition of historically significant objects in the region, and the urgent need to create local organizations to monitor the technical condition of objects and prevent violations of their operation.

The technological process of aerocrete production consists of many operations during which the considerable amount of dust enters the atmosphere. The results of the dispersion analysis show that the great bulk of the formed dust is made by fine particles to 20 microns. The cyclones used in building industry don't remove the dust effectively. To improve the aerocrete production environmental safety an installation of dust collectors on the oncoming swirl flows is requested.

Keywords: Environmental safety, dust emission, purification efficiency, density composition, dust collectors installation

"This review covers various methods of synthesis LaMnO3 ferroics. The general analysis of the solid-phase synthesis reactions methods and wet methods (sol-gel, sorption, co-precipitation) are carred out. The original results of LaMnO3 syntheses from various precursors by means of the in situ method are showned. The advantages and disadvantages of different methods of synthesis are determined. The analysis of synthesis LaMnO3 ferroics published data is shown:
- the structure formation of LaMnO3 in perovskite-type phases occurs at different temperatures, depending on precursors states;
- LaMnO3 perovskite phases differ in symmetry and unit cells parameters at room temperature, depending on the preparation conditions;
- the highest synthesis temperature of LaMnO3 are typical for solid phase reactions method (950-1050 ° C), the lowest - for wet synthesis methods (500-700 ° C);
 - the synthesis conditions effect the stoichiometry of LaMnO3 for oxygen content.
Our studies of structure formation processes of LaMnO3 by in situ method are allowed to define the role of precursors states at synthesis of solid phase reactions methods, adsorption, co-precipitation and sol-gel mixtures.
It is determined that in samples prepared by wet chemical methods, the formation processes of  LaMnO3 perovskite phases occur at lower temperatures than by solid phase reaction (sol-gel precursor - 500 <T <600 ° C; precursors obtained by coprecipitation and sorption methods - at 600 <T <700 ° C and 700 <T <800 ° C, respectively).

"Construction production is connected with emergence of a number of negative impacts on environment. In article main types of the construction works, being accompanied the main are considered by loads of ecology. The special attention is given to a problem of construction garbage, options of a solution with a dump. Versions of the solution of a question of utilization of construction garbage - sorting, processing. Economic aspects of a solution with utilization of construction garbage: Ekonolmiya of materials, decrease in quantity of a waste. "
