Abstract:

Rapid changes in the field of information technologies, growing production and consumption forced by economic growth lead to growth of waste causing the new challenges to waste management. All these fields are widely analyzed by scientists as separate scientific, technological, environmental or economic problems as well as integrated questions. Waste management is analyzed comprehensively and systematically as well as individual questions of waste generation, waste forecasting, waste storage, and other questions. The information technologies (information systems) are engaged in different stage

Abstract:

Waste management is currently a fast-growing environmental business and one of solutions to manage the huge amount of waste being generated on landfills is to use the disposed waste as an energy source. There is a major focus on energy forecasting, highlighting the importance of having reliable data on the volume and composition of municipal solid waste in landfills. However, the lack of historical data is forcing the development of machine-learning based models. This study contributes to this field by proposing a hybrid ANN-based model to forecast the total amount of landfill waste, different

Abstract:

As a public service, municipal waste management at the local and regional levels should be carried out in an environmentally friendly and economically justified manner. Information on the quantity and composition of generated municipal waste is essential for planning activities related to the implementation and optimization of the process. There is a need for reliable forecasts regarding the amount of waste generated in each area. Due to the variability in the waste accumulation rate, this task is difficult to accomplish, especially at the local level. The literature contains many reports on t

AbstractForecasting is the science of predicting events that will occur using historical data and projecting them into the future with some form of mathematical model that aims to handle and policy in the future. In forecasting there are several methods, two of which are Autoregeressive Integrated Moving Average (ARIMA) and Decomposition. ARIMA is a method developed by George Box and Gwilym Jenkins in 1970. The Decomposition Method is a method that decomposes (breaks) time series data into several patterns, namely trend, cyclical and seasonal, and identifies each of these components separately

Abstract:

The article substantiates the need to study the carbonation of concrete and evaluate the maximum carbonization of it. The basic equation of prediction of change in time by concrete cross section of carbonate component of cement-sand fraction of concrete is given. An expression is proposed for estimating the limit value of concrete carbonation (PVC). PVC from concrete composition (amount of used cement) for concrete without additives, compressive strength classes С8/10–С50/60, mixture compositions, grades for ease of laying P1...P5 and G1...G4 for each class of concrete in terms of compressive

Abstract:

In order to maintain the volume of oil and gas supplies, the number of oil and gas wells increases every year, drilling platforms are built, which proportionally increases the amount of sludge and drilling waste mud, which must be recycled. The research gives light to the danger of introducing chemical substances into various natural environments from industrial and anthropogenic sources on an example of drill cuttings from oil fields of Tomsk region.

Abstract:

Municipal Solid Waste (MSW) is a source of large scale emissions of green house gases. Methane and Carbon-di-oxide are primary drivers of climate change and global warming. Methane more specifically has 21 times the capacity to create global warming than Carbon-di-oxide.  This study estimates the emission potential of Municipal Solid Waste (MSW) collected for the baseline year 2016 using UNFCCC’s Clean Development Mechanism (CDM). It was found that the amount of methane that is generated from the SWDS in the baseline scenario in year 2016 is 19,527 (t CO2e/yr). This solid waste in t

This paper examined the characteristics of household solid waste with a hope of contributing to the improvement of solid waste management in Hue city. The study was conducted by collecting, classifying and measuring household solid waste from 62 households in 7 consecutive days. A structure questionnaire was also used in the interviews with survey households to collect data on their demographic characteristics. The results show that the household solid waste was generated evenly on a daily basis with an amount of 286±171g/person/day during the weekdays. The composition of household domestic so

This paper shows the use of dimension stone waste in the manufacture of soil-cement bricks. Initially, a sample of the soil was analyzed for mineralogical composition, particle size distribution (classifying it in the proportion of silt, sand, and clay), and physical performance by plasticity (Atterberg limits specified by standard NBR 7180). A series of soil/waste/cement mixtures were prepared with contents up to 90% wt.% of dimension stone waste. The samples were characterized as mineralogical composition, microstructure, and water absorption after 7, 14, 21, 28, and 60 days. The composition

Medical waste is generated in healthcare institutions and can be of different types. According to its properties, it can be classified as hazardous medical waste or non-hazardous medical waste. Due to its potentially dangerous properties, it is necessary to manage medical waste in accordance with the provisions of the Waste Management Act and the Ordinance on Medical Waste Management (1, 2). In the period from 2015 to 2019, the amount of medical waste grew annually by an average of 8%. In 2020, 7.014 tons of medical waste were generated, of which 74% was hazardous and 26% was non-hazardous med
