“…The incineration technique is more competitive if the produce calory (heating value) is not less than 2000 kcal (8370 kJ/kg) (Dursun & Maaroof, 2016) and suitable if applied to some waste characteristics (e.g., Table 2). The weakness of incineration is generated air pollution residue, including the particulate material usually in the range of 2% to 5% of the original waste on wet basis (Nidoni, 2017), emission of dust, sulfur, and nitrogen compounds as well as dioxins (Krepsztul & Rydzkowski, 2019).…”

The purpose of this paper is to provide information related to waste technology processing. The study was conducted using a literature review technique. This review provides an in-depth discussion of the impact and the recent breakthrough in improving problems arising from the generation and disposal of soiled diapers. Various technologies were highlighted, especially the safer use and cleaner technology, such as biodegradation and composting to maximizing recycle process at a cheaper cost. Moreover, pyrolysis shows an opportunity to improve the efficiency of the recycling process used diapers. Finally, recycling is achievable with an economic incentive if the costs of a series of complicated processes are lower than the value of the end product. Therefore, the best technology for recycling becomes a big consideration. The consideration of which process to use may vary from national and industrial outlook in terms of rate of return, total cost, and environmental. The challenge of recycling is to reduce the cost of waste treatment while providing high-quality final products and need to focus on developing practical and environmentally friendly recovery methods.

“…Paper [8] emphasized that using existing, standard methods of thermal neutralization of polymers such as combustion in special installations significantly increases the load on dust and gas catching equipment. In pyrolysis processing of certain groups of polymers, for example, polyurethanes, the current methods are unstable.…”

This experimental study has confirmed that during thermal decomposition of polymeric waste samples at a temperature of 850 °C, without oxygen access, there is a 90 % drop in the mass of this waste with the release of a large volume of gaseous products. This feature should be taken into consideration in the engineering calculations of reaction chambers, reactors, and connecting gas pipelines. The analytical study was carried out by a method of thermodynamic analysis using the universal estimation system Astra (TERRA). It has been shown that with an increase in reaction temperature there is a change in the composition of the products of thermal destruction of polymeric waste by reducing the mole fraction of СН4 and increasing the proportion of Н2. The calorific value was calculated according to Mendeleev’s empirical formula. The experimental study (a pyrolysis-gas chromatography method) has confirmed the calculation results regarding an increase in the proportion of hydrogen in the gaseous products of destruction with an increase in process temperature. As a result, due to the lower volumetric heat of hydrogen combustion, the total caloric content of the synthesis gas obtained is significantly reduced. For the experiments, a laboratory installation of low-temperature pyrolysis of polymers with external supply of thermal energy was built, and synthesis gas was used as an energy carrier. At the experimental-industrial installation, by a low-temperature pyrolysis method, the synthesis gas of a stable composition with a lower heat of combustion of 24.8 kJ/m3 was obtained. The reliability of the results of the proposed estimation method to the results of instrumental measurements has been shown. Promising areas of further studies have been determined, including the optimization of processes of thermal destruction of chlorine-containing polymer waste; the effective use of hydrogen from the composition of the synthesis gas obtained.

“…In highly developed countries, work is underway to improve and increase the efficiency of biomass combustion processes and the co-incineration of biomass with coal and in synthetic gas circuits. In addition to the development of technology, great emphasis is also placed on the search for new methods of the biomass processing of polymeric materials that have previously caused problems in processing [ 19 , 20 ]. Work is also conducted on the use of carbon biochar and waste rubber biochar as a pigment for black varnishes and for use in the production of steel sheets [ 21 ].…”

The article presents the results of experimental research together with the development of a response function presenting the thermal functioning of a new composite of a phase change material with carbon recyclate. The empirical research proved the improvement of the thermal functioning of the phase change material as a result of modifying its structure with carbon-based recycling material. The conducted experimental tests and statistical analysis proved that the obtained innovative composite is characterized by a more effective distribution of stored heat than the pure phase change material, which resulted in reduction of the heating and cooling time of the package by 10 min. The obtained innovative composite can improve the thermal efficiency of short-term heat storage systems, both in building components and in elements of heating and cooling systems, and translates into their increase in thermal efficiency.
