Problem statement.The solution to the problem of the integrated use of secondary construction resources should be considered in the context of the spread of the world practice of using, processing and reclaiming all valuable waste as secondary resources. This is due to profound changes in the world economy associated with limited natural resources, threats to environmental and social security, an increase in the amount of waste and man-made landfills.The process of managing the flows of secondary resources should be aimed at achieving economic and environmental effects, the definition of which has certain characteristics for various stakeholders in this process: (producers of building materials (waste recyclers), developers (construction companies and organizations), the construction industry (at the regional level, countries).The application of world experience in the use of secondary resources in the construction industry can become the basis for the development of infrastructure for obtaining secondary raw materials from construction waste and attracting them into re-circulation, which will make it possible to more effectively implement the National Waste Management Strategy until 2030, adopted by the Government of Ukraine.The goal of the strategy is to introduce a systematic approach to waste management at the state and regional levels, to reduce the volume of waste generation by increasing the volume of their processing and reuse. Purpose of the article: substantiate the effectiveness of the use of tools for integrated management of secondary resource flows in the construction industry and propose an economic and mathematical model for optimal management of construction waste flows at the level of individual enterprises of the industry in the region. Conclusion. The toolkit for managing waste streams in the construction industry includes information (including statistical, monitoring), analytical, predictive tools for managing the flows of secondary resources. We consider the creation of a unified system of integrated management of the flows of secondary resources (materials) as a condition for decision-making and the effectiveness of the overall management of waste streams in the construction industry, the main goal of which is to achieve a cumulative economic effect from attracting construction waste to a repeated production cycle.The effectiveness of the use of tools for complex management of the flows of secondary resources in the construction industry has been substantiated and a method is proposed for its determination, on the basis of a mathematical model for solving the problem of optimal management of flows of construction waste at the level of enterprises are waste producers, enterprises-processors (producers of building materials from secondary raw materials), the construction industry of the region.

The objective of this study is to perform a diagnosis of the Construction Waste (CW) generation at sites in the city of Recife, Brazil, and obtain indicators to improve waste management. This involved the collection of data through the establishment of partnerships with construction companies that build multifamily residential buildings in the region. To organize the information, a spreadsheet database was developed, containing the survey of the construction characteristics from each construction project, such as the phase, built area, total land area, demolition and excavation area, number of floors, execution time, among others. From this analysis, it was verified that the total CW generation increases as the built area increases. However, the generation rate has an inverse relationship, being higher for the projects with smaller built areas. It is therefore necessary to consider the size of the project in order to use the correct CW generation rate. The results obtained by the analysis of these 20 worksites indicate that new indicators of waste generation are required by construction phase and by size of the built area, in order to properly estimate how much CW was generated and the costs to manage it.

This research aimed the characterization of the current production of construction waste in the city of Manaus, Amazonas, Brazil, and its impacts on the environment of the Amazon Region. The significance of this research work is to contribute to the improvement of the environmental management of waste in the construction sites of the city of Manaus, with the aim of preserving the Amazonian environment. This research also sought to characterize the existing problems in the environmental management of construction waste in four construction sites, with areas greater than 9,000 square meters. The methodology adopted was based on the application of an in situ survey in four construction sites in the city of Manaus, Amazonas, Brazil, administered by three companies representing the construction sector in the Amazon Region. Data were collected at the construction sites in question in the second half of 2018, regarding the types of construction waste produced, respective volumes, destination and associated costs. A comparison was made between constructed areas and volumes of waste produced, characterizing the current situation of construction waste production in the city of Manaus. After analysing the results obtained, it was concluded that due to the high associated costs, companies avoid recycling construction waste, and opt to discharge it in municipal or clandestine landfills, with significant environmental impacts. For this reason, a greater participation of the Public Administration is recommended regarding the adequate management of waste in construction sites, namely offering financial incentives for companies to promote the recycling and reuse of construction waste.

<p>The purpose of our work is to assess the health state of woody plants growing in different habitats of the city of Aktobe. We have studied the health state of arboreal and shrubby plants growing in various urban habitats; the survey was conducted during 2016-2017 by route-visual method. We performed the analysis of species diversity, abundance and density in urban area. The assessment of health state of the trees was made according to V.A. Alekseev. From your data and literature review we established that such species as Ulmus pinnato-ramosa, Acer negundo, Populus tremula, Populus nigra, and Syringa vulgaris have strong winter resistnce in the territory of Aktobe; we registered that only their apex buds and emds of the shoots were frozen in severe winters. The medium-resistant speices include Ulmus laevis and Acer platonoides. They are less plastic and suffer from late spring and early autumn frosts. The Amorpha fruticosa, Vitis vinifera, and Parthenocissus guinguefolia could be considered as the non-resistant species, since they usually freeze up to the snow cover line. The analysis of the vital state made it possible to assess the resistance to urban conditions of the majority of trees and shrubs registered in urban habitats of Aktobe. According to the preliminary data, the origin of the plant and its winter resistance are of main importance when introducing new species to urban area.</p>

Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.
