“…The decrease in surface area was observed due to the collapse of internal structures of biocarbon (adjacent walls breakdown because of the pore enlargement), resulting in a decline in surface area. A similar decrease in surface area with an increase in pyrolysis temperature was also observed by Elnour et al 48 and Dhar et al 47 3.7 Effect of carbonization temperature on the surface morphology and percent carbon content SEM was conducted to determine the surface morphology of the biocarbon samples (Fig. 7) and identify their microstructure.…”

“…After the complete decomposition of hemicellulose, the cellulose resulted in an enhanced surface area as cellulose microfibrils controlled the dimensional modifications. 47 The rise in carbonization temperature to 700 °C also results in pore enlargement. However, the increment above 700 °C leads to a decrease in surface area.…”

“…But, porous biochar can be produced from rice husk through leaching of ash using alkali treatments at low temperatures using the double crucible pyrolyzing method (Ahiduzzaman & Sadrul Islam, 2016). The surface area of biochar derived from coconut fibre is proportionate to the pyrolysis temperature (Dhar et al, 2020). However, molecular and nanoscale biochar research, on the other hand, has mostly been overlooked in Bangladesh.…”

<p>Globally, biochar research and its application for soil improvement have attracted the interest of many researchers, primarily environmental and soil scientists, in the last decade. But, a limited number of biochar research studies have been conducted in Bangladesh. Therefore, a comprehensive study on biochar research is necessary to find out the scope and opportunities of biochar application in the soils of Bangladesh. Generally, biochar can improve the physical, chemical, and biological properties of soils. It also has a significant role in greenhouse gas emissions. The contaminated soils can also be remediated through the judicious application of biochar. In Bangladesh, biochar application enhanced soil pH, organic matter, phosphorus availability, and agricultural production while decreasing soil acidification, microbial activity, and heavy metals mobility. Besides that, there were both positive and negative findings regarding nitrogen availability, greenhouse gas emissions, and heavy metal accumulation. However, this review includes the selection of feedstock, the advancement of pyrolysis technology, the characterization of biochar, and the agronomic and environmental benefits of biochar use. This paper also reviews biochar study and application activities in Bangladesh over the last decade. Further research directions have been suggested to ensure the beneficial and safe application of biochar to agricultural property. </p>

The objective of this work is to investigate the conversion of spent coffee grounds (SCG) into biochar (BSC) and the ecotoxicological effects of the product obtained. The SCG and BSC were characterized by characterized by different techniques (TGA/DTG, FTIR, XRD, SEM, EDS, and EDXRF). Proton Nuclear Magnetic Resonance ( 1 H NMR) was used to characterize the aqueous extract of BSC. The inhibitory effect on lettuce (Lactuca sativa) germination was investigated. Besides, antimicrobial activity evaluation trials were conducted with Azospirillum brasilense and Trichoderma spp. The results showed that in the BSC production process, the extractives and lignocellulosic components in the SCG were partly decomposed. Tests conducted with microorganisms did not reveal any toxic effect of BSC. However, high phytotoxicity against lettuce was recorded for rate 100 t/ha of BSC. This effect was associated with the presence of carboxylic acids identified by 1 H NMR in the BSC extract aqueous.
