It is known that the problem of recycling of electronic waste is becoming one of the topical modern tasks. The main task is to maximize the recycling of materials and minimize the risk to the environment.Modern electronic equipment includes many elements consisting of metals and nonmetals, including plastic. Recycling of electronic waste at the present stage is mainly focused on the recovery of valuable metals. Various plastics are given less attention. However, their content by weight can be up to 50% of the weight of electronic equipment. In this regard, the recycling of plastics from e-waste for the purpose of recycling in electronic equipment is the most optimal approach from both economic and environmental points of view. In order to exclude the reduction of the explanatory qualities associated with the impact of recycling processes, it is possible to use various fillers. The use of fly ash microspheres as a filler in order to increase the performance characteristics is quite possible. Microspheres of fly ash are a product of combustion of energetic coals. They have high mechanical characteristics, are stable, non-corrosive and resistant to high temperatures. In our study Acrylonitrile–Butadiene–Styrene Flame-Retardant (ABS FR) Plastic obtained from electronic waste and fly ash microspheres from coal combustion at GRES 1(https://gres1.kz/) Kazakhstan obtained from the water surface of ash storage were used as matrix. The influence of the amount of fly ash microspheres on the mechanical properties and thermal resistance of ABS FR-based composite material was studied. For this purpose, compositions with microsphere/plastic content in the amounts of 10/90, 20/80, 30/70, 40/60, 50/50 were prepared. The composition was heated to 250 °C and stirred for 5 minutes. The obtained samples were subjected to mechanical tests and DSC/TGA analysis. The composition with a microsphere/plastic content of 20/80 showed optimum properties. Rockwell hardness (R) = 99; impact toughness 22.8 °C = 2.08 J/cm2; compressive strength = 52.84 MPa; tensile strength = 39.45 MPa; mass loss when heated to 400 °C = 21.93%; Material density = 1.016 g/cm3. A further increase in the number of microspheres leads to a decrease in mechanical properties. The obtained material is perfectly suitable for re-manufacturing of electronic components.

Some bacteria synthesize cellulose in the form of a mat of nanofibers (~100 nm in diameter and ~100 µm in length). This Bacterial Cellulose (BC) is highly pure, featuring high crystallinity and remarkable mechanical properties. BC has been utilized to produce nanocomposites in the form of films, hydrogels, and aerogels for a wide range of applications. These applications include the production of electrically conductive fibers, ion-conductive films, highly porous electrodes, and triboelectric layers with potential uses in the development of lightweight and flexible energy storage and generation devices such as batteries, supercapacitors, and piezo- and tribo-electric nanogenerators. The processing method, fillers, and additives employed in the fabrication of BC-based materials play a key role in the properties of BC and the performance of the energy devices.

Pitch, as a raw material rich in aromatic structure, easy to graphitize, high carbon content, and low ash content, is a high-quality precursor for preparing high value-added functional carbon materials. The composition, chemical structure, and group composition characteristics of pitch are different, and the pyrolysis process during heat treatment is different, resulting in completely different pyrolysis reaction kinetics, which determines the morphology, microcrystalline structure, and application range of derived-functional carbon materials. Based on the analysis of pitch composition and structure, as well as the study of thermal reaction behavior, different types (including mesophase pitch, mesocarbon microbeads, carbon foam, self-sintered isotropic graphite, porous carbon and carbon anode) and application of functional carbon materials were prepared in this work. The above work provides guidance for the high value-added application of pitch.

Values of the atomic and molecular orbitals belonging are used for one and two atom systems from the 4th and 5th periods of the periodic table, have been calculated using ab¬ initio quantum mechanical calculations. The energies of selected occupied and unoccupied orbitals surrounding the highest occupied and lowest unoccupied orbitals (HOMOs and LUMOs) of each one and two atom systems, were selected and used as input for our artificial intelligence (AI) software. Using AI, correlations between orbital parameters and selected chemical and physical properties of bulk materials composed of these elements have been established. Using these correlations, the materials’ bulk properties have been predicted. The Q2 correlation for the single atom predictions of the properties: 1st ionization potential, melting point, and boiling point were 0.3589, 0.4599, and 0.1798 respectively. The corresponding Q2 correlations using orbital parameters describing two atom systems increased the capability to predict the experimental properties to the respective values of 0.8551, 0.8207, and 0.7877. The accuracy in predicting materials’ bulk properties was increased up to 4-fold by using two atoms instead of one. We will also present results of the prediction of molecules for materials relevant to energy systems.
