“…Waste consist of different character calorific value and different-sized particles, the average calorific value of which is dependent on external parameters: temperature, pressure, humidity. Average heat of combustion of MSW ~8000 kJ/kg [12][13][14][15][16]. The combustion of MSW consumes a large amount of oxygen O2, which increases considerably with increasing content of the waste plastic materials.…”

At present, processing and recycling of municipal solid waste (MSW) has become more relevant in our country and the world at large. This problem concerns large towns and cities, where every year millions of tons of all kinds of fractions of household waste are produced. Disposal or recycling of solid waste is an environmental issue, but it is associated with the solution of complex technical, energy and economic challenges. The purpose of this study is to identify the advantages and disadvantages of modern methods of processing and disposal of MSW with the prospect of developing and creating a device for recycling MSW taking into account modern approaches to energy saving and environmental protection. The main results of the study are to create a simple, reliable and technically sound method of MSW disposal to obtain additional energy. The significance of the results obtained for the construction industry is the design of a device for the disposal of solid waste with the production of solid combustion products and further their use as building materials and products for various purposes. Because of the technological process of MSW processing, it becomes possible to generate some returns through use of resulting thermal energy for electricity production.

“…At many enterprises and institutions, old technologies prevail and therefore in settlements the waste having the increased danger to the population collects. Burial of this waste does not solve a problem of their neutralization; it only shifts the solution of this problem on the near future [10][11][12][13][14].…”

“…Various kinds of carbon materials such as blocks, powders, emulsions are widely used as important components in the modern industry. For example, carbon materials are employed as biomedical substances, materials used in chemical sensors manufacture for applications in optoelectronics or in medical devices, electronic stuff, aerospace items, and so one (Delport and Badenhorst, 2016;Xiao et al, 2016). In the early stage of the carbon industry, tar, pitch, naphtha and coke were developed as raw materials for the manufacture of graphite powder (Choi et al, 2017;Mearz et al, 2018).…”

In this research, high-density and high-strength carbonized carbon blocks were manufactured by coke sintering resulted from heat treatments of biomass pyrolysis tar. First, the molecular weight distribution of the tar was controlled through a pressurized heat treatment at 365°C and then this heat-treated tar was treated using a delayed coking system to obtain the self-sintering coke. Finally, carbon blocks were molded from the self-sintering coke and carbonized at 1100°C for 2h. Through rapid decomposition of the high molecular weight compounds in the tar at 360°C, the molecular weight distribution of tar was confirmed to be controllable by this treatment stage. During carbonization was observed a swelling in carbon blocks manufactured that contain more than 15 wt% of volatile matter from 150-500°C. The optimum conditions of the two heat treatments stage were established to be 310°C for 3 h and 500°C for 1.5 h. The highest density and highest strength of the carbonized carbon blocks manufactured were 1.44 g/cm3 and 68.7 MPa, respectively.

“…pyrolysis might be used [4]. Due to the temperatures used, pyrolisis processes can be divided into: low temperature (< 350°C), medium temperature (350-800°C), and high temperature pyrolysis (> 800°C) [5]. Medium-and high temperature pyrolysis is commonly used to biochar production, which is currently tested in the processes of enriching degraded soils, water cleaning, in construction, in electronics industry, in metallurgy, in medicine, and in cosmetics [6].…”

Utilization of waste forest biomass: pelletization studies of torrefied sawmill wood chips

et al. 2019

The paper presents the effects pelletization process of torrefied waste forest biomass -sawmill wastes. The sawmill waste are generated in significant quantities and has significant energy potential. The use of torrefaction and pelletization process enables to produce mechanically durable fuel pellets. Aim of the studies was to evaluate the effect of different kind of additives (binders) to torrefied waste forest biomass on pelletization process characteristic (production capacity, energy consumption) and properties of produced pellets (i.e. density, mechanical durability). The most effective binder among the tested was modified wheat starch. Pellets made with this addition were characterized by the highest mechanical strength.
