“…An example is where energy storage operators can dispatch to the highest-valued use, thus generating a higher return unlike just supplementing energy systems. In this sense, one can agree that a smart grid and net metering network, driven by energy storage, demand side management and interconnection will shape the future outlook of the utility market, creating an Internet of Energy [ 71 ].…”

Climate change and the potential depletion of fossil fuels have increased international demand for alternative and renewable energy sources. In terms of the energy sector, for example, most of the South-East Asian countries (SACs) have a large number of biomass sources due to their vast forest resources and agriculture-based economies. Thus, the critical review was aimed at highlighting the overview of biomass energy in South-East Asia as a dynamically developing region, in order to obtain economic and environmental benefits from the existing sources of biomass in the world. The current review analyzed the sources of biomass, as well as their energy potential, use, and management, based on reports from different countries, published studies, and scientific articles. In SAC, the main sources of biomass were found to be coconut residues, oil palm residues, sugar cane residues, rice straw, rice husks, wood waste, and firewood. The combined annual biomass potentials in the forestry and agricultural sectors in South-East Asia were approximately over 500 million tons per year and more than 8 gigajoule of total energy potentials. The study identified the challenges and barriers to using biomass in these countries to achieve sustainable use of biomass sources and recommended sustainable approaches to using biomass energy by comparing traditional uses of biomass. Smart grid technologies have ways for solutions for better electric power production and efficient ways for distribution and transmission of electricity. Smart grids require less space and can be more easily installed when compared to traditional grids because of their versatilities. Upcoming challenges include technology optimization for the following uses of biomass energy: direct combustion of woody biomass; pyrolysis and gasification of biomass; anaerobic digestion of organic waste to produce biogas; landfill gas production direct incineration of organic waste. The barriers in this technology are emissions of carbon and nitrogen oxides, unpleasant odors, as well as the uncontrolled harvesting of biomass, which can harm nature.

“…In the AC clay, 57.7 wt.% of particles were >44 μm, which would facilitate the drying process by assisting in the formation of capillaries and promoting water flow. However, excessive amounts of particles of this size could decrease the mechanical strength of such products (Nicolas et al ., 2020). Thus, the AV clay was the most plastic due to its small coarse-particle content (7.5 wt.%).…”

“…Red ceramic products mainly include roof tiles, structural blocks, and bricks, which have high plasticity that requires considerable amounts of water for their shaping through extrusion. In the subsequent drying process, water is removed from the molded material using significant amounts of thermal energy for the firing process (Inocente et al, 2017;Nield & Simmons, 2019;Nicolas et al, 2020). Nevertheless, some clays have no appreciable plasticity and therefore do not require considerable amounts of water for extrusion.…”

“…The alkali and alkaline earth (K + Ca) metal content in the coal discard average 7.27%, 5.68%, and 9.37% for GTS, PCD, and LCS respectively, and are related to the feldspar species in the discard. Feldspar-containing coal discard could promote the formation of the glassy or vitreous phase (Nicolas et al, 2020) with the PCP resin during pyrolysis of the mixture. This reaction is important for the densification of coal composites during pyrolysis.…”

“…As stated in (Table II), GTS and LCS discards recorded higher oxygen contents compared to PCD. Based on this, it is likely that GTS and LCS are weathered coals and contain a significant amount of oxygen functional groups (Gao et al, 2017;Jian et al, 2019;Nicolas et al, 2020). It could also suggest that GTS and LCS discards likely contain more vitrinite (reactive macerals) whose chemical structure is generally characterized by a relatively high oxygen content compared to other maceral groups (Whitehurst, 1978;ICCP, 1998;van Niekerk, 2008;Roberts, 2015).…”

In response to the enormous amounts of coal discard generated during coal mining and preparation, the development of an efficient and sustainable strategic use of this resource is essential. Furthermore, the rising urban population over the next decades is confronted with the depletion of quality raw materials for building components. To this end, this study reports new information on the morphology, water absorption, and flexural strength properties of ceramic composites produced from three different coal discards and polysiloxane pre-ceramic polymer (PCP) resin. In addition, test results relating to the continuous operating temperature, chemical resistance, and efflorescence potential of the composites are presented. The results show that the water absorption and flexural strength of the coal composites, up to 1.94% and 36.46 MPa respectively, exceed the requirements for ceramic and clay roof tiles. The continuous operating temperature of composites is found to be more thermally stable than conventional roofing tiles (concrete and ceramic) between ambient temperature and 600°C. In addition, the excellent chemical resistance of the composites (94.43%-99.98%) compared to conventional roofing tiles (67.82%-99.97%) eliminates the need for additional external coatings. The interesting results documented so far suggest that this technique could be used to produce low-temperature application building products such as bricks, panels, roofing tiles, etc. This new recycling technique offers an excellent opportunity to eliminate enormous volumes of coal discard and to advance the circular economy in the coal industry.
