“…CCRs are geochemically complex and highly enriched with extremely heterogeneous constituents, composed of (in)organic pollutants (Hower et al 2017a, b;Verma et al 2015;Liu et al 2008). They contain potentially hazardous toxic elements, radiotoxic radionuclides (Turhan et al 2018;Wang et al 2016a, b;Hower et al 2016;Sahu et al 2009Sahu et al , 2014Sahu et al , 2017, unburned carbon, rock-fragment, amorphous glass, micron to nanoparticles/minerals Islam and Hayashi (2008), Farhaduzzaman et al (2012), Farhaduzzaman et al (2013a, Islam et al (1992), Bakr et al (1996) a Koukouzas (2007), b Baba et al (2010), c Belkin et al ( 2009) (Jambhulkar et al 2018;Dai et al 2014;Zhao et al 2017;Hower 2012). CCRs are originated mostly from the inorganic constituents of feed coal (Hower et al 2017a, b;Fungaro et al 2013;Hower 2012;Lu et al 2012a, b;Islam et al 2011; Koukouzas In BTPP, about one million tons (Mt) of coal is being mined from BCM annually, of which 65% is combusted for power generation (Howladar 2013;Howladar and Hasan 2014;Howladar and Islam 2016).…”

To represent a comprehensive scenario regarding the coal mining and coal-fired power plant activities in a developing country (Bangladesh) and to understand the total environmental impacts, potential coal resources of Bangladesh, environmental geochemistry and dispersion of pollutants, eco-toxicological impacts, human health risks as well as socioeconomic impacts are evaluated in this chapter. Potential coal reserves along with the future plants are estimated. Technogenic sources of environmental pollutants including environmentally toxic heavy metals, health hazardous radionuclides, persistent organic pollutants, suspended particulate maters, etc. are assessed. In doing so, scarce associated data from coal mine (Barapukuria, Bangladesh) and Barapukuria coal-fired power plant (BTPP) of Bangladesh have been reconciled by using and arguing the previous works around the globe. Immense and proper literature reviews as well as the existing data on Barapukuria coal mine and BTPP are tabulated to compare and understand the condition along with the potential prevention and remediation approaches.

“…Arsenic comes to the ecosystem in the form of arsenic trioxide and dispersed to soil, water and air. Arsenic concentration in fly ash generally ranges from 4 to 440mg/kg; however, depending on the quality of coal the concentration may reach up to 1000 mg/kg (Jambhulkar et al, 2018).…”

Arsenic is one of the major toxic minerals that is naturally present in the environment and have significant adverse effect on animal health. Inorganic arsenic present in ground water enters the food chain through irrigation and ultimately affects the animal and human health. The presence of arsenic in groundwater in India is the most serious health hazard. Lower Gangetic region which includes West Bengal, Jharkhand, Bihar, Uttar Pradesh are in serious threat to arsenic contamination because of its geographic location. Ground water is the major source of arsenic toxicity, though arsenic also enters the animal body through feeds and fodder. Arsenic toxicity is a serious health hazard because of its oxidative damage capacity. Apart from that, it has the properties of carcinogenicity, neurotoxicity, hepatotoxicity and nephrotoxicity. Chronic arsenic toxicity in animals is more commonly seen than that of acute toxicity. Arsenic toxicity can be avoided by removing arsenic from ground water which is a very tough task. However, Government of India has taken some serious steps to reduce the arsenic load from ground water. Effects of arsenic toxicity, specifically, oxidative damage can be reduced in the animals by various dietary treatments such as Vitamin E, vitamin C, probiotics, minerals like Se, Zn, herbal drugs like turmeric, ginger etc. However, these treatments are reported to have very less effect on removing arsenic from body. Therefore, significant and continuous efforts are needed to develop new technologies to reduce the arsenic load from ground water as well as from animals.

“…The huge quantity of such fly ash has adverse effects on the environment, leading to worse global climate change [ 7 ]. For instance, the improper disposal of fly ash to settling ponds may cause environmental contamination, some of heavy metals that are present in fly ash and, if present in high concentrations, are phytotoxic; others are toxic to fish and aquatic organisms [ 8 , 9 , 10 ]. The environmental contamination due to the leaching of heavy metals from coal fly ash ponds are: phytotoxicity, the contamination of soils and vegetation, and ground and surface water pollutions [ 6 ].…”

Fly ash polymer composites are innovative high-performance materials that reduce the environmental worries and disposal complications of heavy industry produced fly ash. This study developed and characterized such composites of high-density polyethylene (HDPE) matrices and found that the use of small (50–90 µm) particles of fly ash could give rise to the tensile modulus (~95%) and tensile strength (~7%) of their reinforced composites when compared to neat HDPE materials. While these results themselves convey a strong message of how fly ash can be effectively utilized, this was not the key aim of the current study. The study was extended to examine the effect of fly ash particle size on the recyclability of relevant HDPE composites. The extrusion-based multiple recycling of composites gave slightly lower mechanical properties, primarily due to filler/matrix delamination when large fly ash particles were used. Compared to freshly made fly ash-filled HDPE composites, although using small (50–90 µm) fly ash particles reduced the tensile modulus and tensile strength of recycled composites, the values were still far above those from neat HDPE materials. This novel insight directs the effective utilization of fly ash and provides long-term sustainable and economical solutions for their practical applicability.
