Non-biodegradable waste has reached the top of the global priority list. The increased use of materials such rubber, glass, and plastic in our daily lives is posing a health and environmental risk. 6.3 billion tonnes of plastic and 3.5 million tonnes of rubber waste have been generated so far. Concrete is the main component for the construction of a building. It is manufactured by using the materials like cement, coarse aggregate, fine aggregate and water. It is used to make structural elements such as beams, columns, foundations, and slabs etc. The literature study reveals that there is very little literature on the use of rubber, hence there is a lot of research that needs to be done. In this study, rubber is cut into 20mm aggregates and immersed in sodium hydroxide (NaOH) and calcium hypochlorite Ca(ClO)2 solutions for 6, 24, and 72 hours, respectively. The rubber is then washed after being removed from the liquids the coarse aggregate was partially replaced in the concrete mix. This paper presents the results on analysis of scrap rubber, which is used in the building industry as a partial replacement for coarse material. With the usage of rubber, it is not only possible to reduce the use of natural coarse aggregate, but also able to decrease pollution. From the results it is found that strength and workability is increased slightly with the effect of rubber waste. [ABSTRACT FROM AUTHOR]

Climate changed, in this case was global warming, was the greatest environmental risk. Global warming could be understood as the rise of the average temperature of the surface of the Earth. It had been degrading our environment. When our environment was degraded, the built form was also affected, the life of all people would be seriously affected too. Actually the efforts to fight degrading environment were the responsibility of all people, not only the domain of the government. We had to contribute to fight global warming with any effort as much as we knew, as long as we could. There was also the issue that a vegetarian lifestyle could be one kind of many solutions to fight global warming, even only small. While in other countries some aspects of this issue had been implemented, we in Indonesia never took a closer look at this lifestyle. Even, the persons who held a vegetarian lifestyle also did not know their lifestyle could contribute to reduce global warming. Furthermore, in this pandemic Covid-19 a vegetarian lifestyle was much more relevant to be considered. The objective of this paper was to explore the possible things to manage the environment through some aspects of a vegetarian lifestyle. Methods used by investigating literatures of global warming and vegetarian. Data collection carried out from persons who held a vegetarian lifestyle even though rare persons held it, by giving them closed-ended and open-ended questionnaires. Because this time was still on pandemic Covid-19, both questionnaires were conducted through Telegram Group of Vegan Way, and through Facebook too. The data obtained then analysed qualitatively the possible things to manage the environment through some aspects of respondents' vegetarian lifestyle. All were connected so that the conclusion could be drawn. The conclusion was, some aspects of a vegetarian lifestyle such as consumed a plant-based diet, reduced livestock farming, could maintain our environment – even only small - among other big categories to fight global warming.

The paper assesses the environmental risks of the impact of sewer networks on the whole of the environment components such as atmospheric air, soils and water environment as a prerequisite for sustainable urban development. An algorithmic support for the analysis of environmental risks that occur during operation or in case of emergencies in sewer networks has been developed. The risk assessment was performed for 11 sewer shafts in Kharkiv based on field measurements: for atmospheric air, according to four environmentally hazardous gaseous substances generated in sewer networks; for water environment and soils, according to 12 indicators and pollutants. A high level of environmental risk to atmospheric air has been found in three shafts. Environmental risks to the water environment and soils are imposed by phosphates and synthetic surfactants.s [ABSTRACT FROM AUTHOR]

Vietnam has two urban railway investment projects, one in Hanoi and one in Ho Chi Minh city. They are key national projects implemented with State capital and Official Development Assistance (ODA) capital of countries such as Japan, China, and Korea. Urban railway projects in Vietnam, in general, and the Ho Chi Minh City (HCMC) urban railway project, in particular, are falling behind schedule and having cost overruns. Negative reactions have been expressed from both society and the government. The main reason for the problems is the lack of experience and improper approach to project risk management. Perceptions related to the interaction and mutual influence between risks as well as their effects on the implementation of urban railway construction investment projects in Vietnam have not been modeled and explored in great detail. Therefore, this paper comprehensively seeks to identify and assess the impact of risks on the cost, schedule, and quality of the HCMC urban railway project. In particular, this is a case study of Ben Thanh-Suoi Tien Line 1 railway project. Twenty-seven risk factors affect this railway project, of which (i) seven social risk factors; (ii) seven technical risk factors; (iii) seven economic risk factors, (iv) two environmental risk factors; and (v) four political risk factors. In this analysis, Analytical Network Process (ANP) was applied to assess the priority of these risk factors. The research results showed that the economic risk group had the largest normalization risk priority index (NRPIe = 0.334), the technical risk group was ranked the second (NRPIt = 0.276), followed by social, political, and environmental risk groups with an NRPI of 0.182, 0.140, and 0.067, respectively.

The article studies the topic of oil-containing wastes generated in oil production and refining and having a significant negative impact on the environment. The problem is that only a small amount of oil-containing wastes is currently processed with the help of technologies. To prevent environmental pollution and threats to public health, enterprises need to take measures to neutralize and reduce the hazard class of oily waste for oil storage facilities and distribution depots. The paper presents the case of terminal sludge collectors in Arkhangelsk, situated in the northern part of the Russian Federation. The authors give the rationale for reducing the hazard class of oil-containing wastes, slurry cards stored for long periods at the Arkhangelsk oil transshipment complex. A technology for lowering the hazardous class of oily waste is suggested. It includes several stages and implies the division of oil sludge into layers and splitting the treatment process into phases. The waste disposal treatment consists of dosage, heating, mixing of the solid phase of the waste with organic substances, preparation and heat treatment of mixtures. The application of the method allows for the neutralization and cure of oil-contaminated materials with optimal energy consumption and the use of domestic commercially available equipment.

Emerging environmental contaminants such as pharmaceutical and other chemicals can affect human health. This show the importance of eliminating pollutants from water by using sustainable carbonaceous materials such as activated carbon. Porous activated carbon has been used in many critical periods of human history. Because of the numerous environmental advantages that lignocellulose precursors and biomass sources provide have risen to prominence as primary raw materials for this product and have excellent performance and a low risk of side effects. From the adsorbent and adsorbate properties (as well as operating conditions) to adsorption, this paper provides a short review of the many elements that influence the adsorption process, from the manufacture of activated carbon to its uses of it. Research and development needs are found in a review of the available literature, which leads to more widespread and long-term use of activated carbon to remove pharmaceuticals from water.

To date , a big problem in cities is thermal power plants. Significant territories are required for their arrangement, they are also foci of accumulation of heavy metals and have increased radioactivity. Heavy metals and radiation enter the environment, either by air or with ground water. In addition, thermal power plants pollute reservoirs by dumping warm water into them, as a result of which a chain reaction occurs, the reservoir becomes overgrown with algae, the oxygen balance is disturbed in it, which in turn threatens the lives of all its inhabitants. This article discusses environmental pollution caused by thermal power plants, which lead to obvious social and environmental problems, and primarily to deterioration of health and increased risk of premature death of the population living near thermal power plants, as well as degradation of biota. The diversity of animal and plant communities is decreasing, as well as the recreational potential is decreasing. The combination of these negative factors affects the quality of life of the population. In this paper, an assessment is given on the load of the heat power industry of the Almaty region on the environment. By calculation, emission standards were determined for various environments, including standards for maximum permissible emissions of pollutants into the atmosphere from stationary sources, discharges of pollutants into water bodies, terrain, filtration fields, waste water storage, standards for the disposal of production and consumption waste.

The article assesses the impact of the anthropogenic environment on children's health as a factor in environmental justice. The study of the negative impact of xenobiotics on the human body is an important task in environmental studies, since most of them are part of the human body. With the depletion of essential chemical elements, there is an excessive accumulation of metal toxins. This can lead to oxidative stress and various dysfunctions of the body. The development of information technologies, in particular digital ones, will make it possible to monitor the quality of products; monitor anthropogenic risks in areas hazardous to health. Introducing artificial intelligence in especially hazardous industries will reduce environmental risks and ensure environmental justice in any area, regardless of their socio-economic level.

Nitrate-contaminated water resources are a major environmental issue that poses a serious hazard to human health around the world. Furthermore, significant levels of nitrates in water sources aid the eutrophication process. As a result, removing and reducing effluent and water resources below the stipulated limit was critical. Currently, nitrate may be removed from municipal, industrial, and agricultural wastewaters using a variety of physical and chemical processes. Clay was chosen as an adsorbent in this study because of its non-toxicity, global availability, low cost, and physico-chemical properties (high surface area, ion exchange capacity, high absorption properties and catalytic properties). The studies were carried out to evaluate the nitrate adsorption isotherm at ambient temperature, as well as the impact of a variety of parameters such as contact time, adsorbent mass, pH, agitation speed and primary Concentration of adsorbate. The results showed that the optimal circumstances of experimentation for reducing nitrates in burned clay were adsorbent dose 12.5 g, pH=7, agitation speed 250 rpm, contact period 2 hours, adsorbate concentration 10 mg/l and The experimental results were examined using Frendlich and Langmuir isotherm models. For nitrate adsorption onto burnt clay material, the Langmuir adsorption isotherm was shown to be the best model. This research clearly demonstrates that burnt clay grains can be employed as a reduced adsorbent for removing nitrate from water. [ABSTRACT FROM AUTHOR]
