Article
In the present study, local flax straw waste biomass samples were studied for their physical and chemical characteristics using a thermogravimetric analyzer (TGA) and thermal properties. Thermochemical conversion of the flax straw samples was performed in an electrically heated horizontal tube furnace from 400 to 600℃. Thermal analysis of the flax...

While fluidized bed coal combustion technology has advanced significantly, attrition and its impact on combustion remains a problem. Using a bench scale fluidized bed unit, we examined the experimental attrition data for batches of coal ash particles. Experiments were carried out in the presence of bed material (sand) by adding coal particle to the...

The electrochemical oxidation (EO) of phenolic wastewaters mimicking olive oil mill effluents was carried out in a batch stirring reactor using Ti/IrO2 anodes, varying the nature (NaCl and Na2SO4) and electrolyte concentration (1.8–20 g L⁻¹), current density (57–119 mA cm⁻²) and initial pH (3.4–9). Phenolic content (TPh) and chemical oxygen demand...

Efficient waste management, including proper utilization of municipal solid waste (MSW), is imperative for a sustainable future. Among several management options, pyrolysis and combustion of MSW has regained interest because of improved combustion techniques. This work aims to investigate the thermal conversion and combustion characteristics of ref...
Article
Numerous models have been developed in Aspen Plus for the combustion of different coal types in fluidized bed reactors. However, these models are case‐specific, particularly with respect to coal type and bed reactor type, implying limitations to general application of these models. Moreover, these processes were generally developed step‐wisely by e...

This work aimed at studying the photochemical treatment of a landfill leachate using ultraviolet light, hydrogen peroxide, and ferrous or ferric ions, in a batch recycle photoreactor. The effect of inorganic carbon presence, pH, initial H2O2 amount (0-9990 mg L-1) as well as Fe(II) (200-600 ppm) and Fe(III) (300-700 ppm) concentrations on the total...
Article
The steady expansion of the city of Astana and the increase of airport capacity is leading to an increase in municipal solid waste generation. The purpose of this study was to perform compositional analysis of the municipal solid waste produced at the Astana International Airport and evaluate different waste management scenarios in terms of greenho...

Nowadays, comprehensive perception of the tar characteristics generated from municipal solid waste (MSW) and coal to guide pyrolysis or gasification gas yield upgrading and cleaning has attracted massive research attention. In this study, MSW and coal samples were chosen as principal components. The mixture of these products was pyrolyzed in a hori...

The exponential population growth in urban areas makes existing solid waste management policies and strategies challenging. The situation becomes more strenuous in fast-growing cities where increasing waste production can hardly be met by the capacity of existing facilities. Practices like waste prevention, recycling, reuse, and recovery are fundam...
Article
In this study, the organic fraction of municipal solid waste (Org-MSW) was blended with high-volatile coal (HVC) in proportions of 25/75%, 50/50%, 75/25% by weight. Pyrolysis of these mixtures was then investigated in a thermogravimetric analyzer (TGA) and a horizontal tube furnace under a nitrogen environment. The mass loss rate of samples, differ...
Article
This study presents the results of a seasonal municipal solid waste composition campaign, that took place over the period of September 2017 to June 2018 in the capital city of Kazakhstan, Astana. Four sampling campaigns were conducted in order to identify the seasonal variation of municipal solid waste composition, recyclables and energy potential...
Conference Paper
In contrast to pulverized coal combustion systems, fluidized bed technologies offer significant advantages such as a low temperature environment and lower NOx, SOx emissions. Another advantage is the potential utilization of a wide range solid fuels such as biomass and low rank coals with high ash content. In this study, a bituminous coal from the...
Article
Buildup of vast quantities of municipal solid waste (MSW) including refuse derived fuel, organic fraction around the urban areas has negative environmental consequences. Gasification and pyrolysis of municipal solid waste could be an attractive option to utilize or convert to a valuable product. This study investigates the thermochemical properties...
Conference Paper
The gradual expansion of the city and increase of airport capacity of Astana is leading to an increase in the amount of household-like solid waste generation. Thus, there is a need for sustainable and efficient waste management plans which requires investigation of morphological and experimental studies data on the solid waste derived from Astana I...

Landfilling remains the most widely applied technologies for the disposal of municipal solid waste (MSW) practiced worldwide due to its proven economic advantage and simplicity over other alternatives. Nevertheless, its adverse environmental impact and the necessity for large land areas are provoking research on other technologies, such as combusti...
Conference Paper
This study provides thermogravimetric and tube furnace analysis of Refuse Derived Fuel (RDF) obtained from the landfill of municipal solid waste (MSW) in Astana city. The morphological results of MSW have showed a maximum value of refuse derived fuel (RDF) in the waste to be in the range of 10% in two seasonal waste sorting campaigns. TGA investiga...

The present paper provides a detailed analysis of the current situation on municipal solid waste (MSW) management in Kazakhstan with focus on the two major cities, Astana and Almaty, the current and former capital of the country. Untill recently, ninety-seven percent of the MSW was disposed in open dumps and substandard authorized landfills. Ninety...
Article
In oxy‐fuel combustion, fuel is burned using oxygen together with recycled flue gas, which is needed to control the combustion temperature. This leads to higher concentrations of sulfur dioxide and sulfur trioxide in the recycled gas, which can result in the formation of sulfuric acid and enhanced corrosion. Current experimental data on SO3 formati...
Article
The purpose of this work was to study the treatment of a leachate coming from the municipal solid waste landfill of Astana (Kazakhstan). Physical (striping and adsorption), biological and photochemical processes were applied separately or in combination, and the treatment efficiency was attended in terms of carbon and nitrogen removal. The leachate...

Astana is the capital and the fastest growing city in Kazakhstan, with more than two-fold population growth in the last 15 years. This increase in population is inevitably connected to rapidly growing energy consumption and increased numbers of transport vehicles, which in turn have an impact on the air quality of the city; the air pollution levels...
