Trends in housing development should be based on the geographical location and climatic conditions of the region, national characteristics and culture, natural resources, transport links, density and living standards. Construction significantly affects the socio-economic development of the region. In this regard, increasing the sustainability of the regional construction complex, which is based on the building materials industry and the construction industry is a relevant and promising area of research.Demand in the building materials market continues to stimulate increased interest in the development of new types of efficient and inexpensive building materials. Since construction is one of the most material-intensive sectors of the economy, which consumes a large number of construction materials and products, various measures are taken to reduce their cost.In this regard, recently in the construction seek to make greater use of local building materials. This allows you to unload transport from long-distance transportation and significantly reduces the cost of construction. However, the building materials industry cannot develop by focusing only on natural sources of raw materials, as the costs of their extraction and processing are constantly growing. The use of man-made waste provides production with a rich source of cheap and often already prepared raw materials, which reduces the cost of manufacturing building materials.One of the promising areas in the construction of affordable housing is the maximum use of building materials and products that can be obtained from local raw materials and industrial waste. As local building materials are offered: clay, sand, soil, straw, reeds, flax. The use of industrial waste solves both environmental, fuel and energy problems and expands the raw material base of building materials.

Material consumption of production of building materials is determined by the amount of raw materials used for their production, to the total output. One of the ways to reduce material consumption is the use of industrial waste as the main raw material for the production of new construction products. Most of the waste generated as a result of the activities of enterprises are man-made raw materials for the production of products such as brick, lime, cement, etc.Given that man-made raw materials are similar to the natural composition and physical properties and even has a number of advantages (heat treatment, increased dispersion, etc.), the manufacture of building materials from it is usually profitable and justified [4, 5].

Results of longstanding researches of Satbayev University scientists on the development of modified building materials to strengthen cracked mountain structures based on industrial waste are considered. Industrial processing of technogenic raw materials (enrichment and processing waste, overburden and enclosing rocks), which is similar in composition to natural and used in conventional trend, scarcely different from industrial processing of mineral raw materials. Creation of effective technologies for the processing of technogenic raw materials is an urgent task, which make it possible to obtain competitive products from it for various industries. Various methods of preparing solutions for strengthening of fractured rocks and building structures are analyzed. Research results of tailings of the Balkhash Mining and Metallurgical Combine and preparing solutions for strengthening fractured rocks and underground mining structures are presented. Rock mass strengthening in cracked areas is achieved by adding substances into the cracks, which after hardening and solidification with rocks, increase its shearing resistance characteristics. The most widespread hardening methods were cementation during mine workings (underground structures) in fractured rocks. Significance of obtained results for construction industry is in expansion and reproduction of raw material base of building materials industry through the use of Mining and metallurgical complex waste (tailings) and development of resource-saving technologies. Practical significance of work is in the detailed development of modified method for the production of building materials and products.

It is shown that at present the current system of environmental regulation in Russia is divorced from the real context in which to exist. One of the most promising areas for the use of waste production is ─ involving them recycled as secondary material or energy resources. On the basis of waste oil shale obtained heat-insulating materials with high physical-mechanical indicators. Due to the involvement of industrial waste in manufacturing of heat-insulating materials may dramatically change the parameters of the raw material base of Russia, which also contributes to reducing environmental impact in the regions. The use of waste fuel and energy complex: inter-shale clay and slate slag in the production of insulating materials contributes to recycling of industrial waste, the protection of the environment and expansion of raw materials base for production of ceramic building materials. The compositions of the developed compositions, proposed to obtain a lightweight brick and a porous filler, the authors of this article obtained three patents of the Russian Federation. Utilization of industrial wastes contributes to the development of "green" economy.

The article deals with the manufacture of modern structural ceramic materials from clay and loam deposits of the Republic of Sakha (Yakutia). The importance and relevance of the development of the production of building materials from local raw materials is emphasized, since this will certainly affect the effectiveness of the construction complex as a whole. The successful development of the construction complex is capable of not only stimulating growth in all sectors of the economy, but also contributes to solving the most pressing social problems. Today, Yakutia has huge reserves of mineral raw materials for the production of a wide range of building materials and products. Of practical interest are wall materials made from clay soils. Given the features of the region’s raw material base, this work focuses on additional processing of traditional material. Controlling the complex physicochemical and structural-mechanical transformations that occur during heat treatment, a methodology has been developed for creating a composite material that will allow competitive innovative materials with enhanced strength properties to be produced with a reinforcing element with a glassy phase matrix of mullite crystals. The fabricated samples have a wide range of physical and mechanical properties and allow using it as a high-quality structural building ceramics, as well as industrial floor technical tile.

Increasing Demand

With concerns about climate change and the search for sustainable construction materials, significant attention is now being paid to Africa's natural resources. Ethiopia, known as Africa's political capital, has a rapidly expanding economy with increasing demand for new construction materials. Through public private partnerships projects the country is developing a sustainable business model to promote bamboo as a raw material. The subtropical zone of Ethiopia is home to approximately 65% of Africa's bamboo resources, an area of over 1 million hectares. Bamboo is potentially an ideal source of local, sustainable purpose-engineered building materials for growing cities not only in Ethiopia but across Africa. Production of conventional construction materials such as steel and concrete is expensive, highly energy intensive and unsustainable, requiring large quantities of water and is strongly dependent on imported raw materials. Bamboo is a renewable building material widely cultivated in Ethiopia but not yet utilized in modern construction. Structural Bamboo Products (SBP), similar to engineered wood products, have excellent potential to partially replace the use of more energy-intensive materials. Projects such as African Bamboo are taking steps in managing, cultivating and using Ethiopian bamboo species to help mitigate rapid deforestation in East Africa by creating alternative “wood” sources and sustainable business opportunities.

The circular economy is a process through which elements that have already been used are reincorporated and given a second use so that they can reduce the consumption of virgin raw materials. This article shows how, from the reuse of an agro-industrial waste such as corn husks, a biomaterial can be developed that manages to standardize the properties of materials such as paper and cardboard, thus allowing the development of single-use products that replace the excessive expense of materials such as polymers. In this article, it will be possible to show how from the process of transforming an agro-industrial waste into a raw material base, it is possible not only to reduce the number of raw materials discarded but also to redesign a product that not only contributes to the environmental component but also facilitates the processes of economic sustainability when generating products. As a practical case, a comparison is made between traditional fast-food packaging and how from these, a new packaging proposal can be generated, which starts from the principles of circular economy and complements sustainable design processes to make more efficient manufacturing of the mentioned product.

The environmental situation in Russia is characterized by a high level of anthropogenic impact on the environment, significant environmental consequences of past economic activity. Their disposal and storage costs 8-10 % of the cost of products, so the disposal of such waste is of paramount importance.Due to the involvement of multi-tonnage waste in the production of ceramic materials of mass consumption, which include wall materials, it is possible to radically change the parameters of the raw material base of Russia, which also helps to reduce environmental tensions in the regions. The reduction of reserves of traditional natural raw materials makes us look for new ways to replace it with different types of waste. The experience of advanced foreign countries has shown the technical feasibility of this area and the use of more as a tool to protect the environment from pollution. However, almost all basic building materials can be made from waste or from waste in combination with natural raw materials. On the basis of fusible clay and waste basalt-gabbro-norite charge, which is formed in the production of mineral wool obtained ceramic brick with high physical and mechanical properties, brick grade M150 and above. The absolute advantage of the use of multi-tonnage waste is the unloading of the environmental situation, which contributes to the solution of industrial waste disposal and environmental protection. Innovative proposals for the use of waste from the production of mineral wool in the production of wall materials - ceramic bricks based on fusible clay, the novelty of which is confirmed by patents of the Russian Federation.
