“…The wideband observed at wavelength of 3200-3400 cm -1 is attributed to -OH from H 2 O, or phenolic groups (Chen et al, 2008;Melo et al, 2013). However, samples PPL350 and PPL450 did not show hydroxyl peaks in these regions; the loss of OH functionality is a consequence of reactions of decarbonylation, decarboxylation, and dehydration promoted with the increase of the pyrolysis temperature (Cuixia et al, 2020). The absorption in the region between 2920 and 2885 cm -1 (CH stretching) was attributed to aliphatic functional groups (Melo et al, 2013), and the increase in band intensity in the region of 1600 cm -1 showed the presence of ketones and conjugated quinones (C = O and C = C).…”

This study aimed to investigate the effect of heat treatments on the total pore volume, surface area of pores, structural characteristics, and functional groups of the materials which derive from the carbonization and pyrolysis of poultry litter. These processes were carried out in porcelain containers containing poultry litter samples, which were then placed in a muffle furnace. The treatments corresponded to three temperatures: samples carbonized at 250 °C and pyrolyzed at 350 and 450 °C. The surface porosity of biochars provides a suitable dimension to improve the water holding capacity, and surface functional groups may help to improve soil fertility. The influence of the temperatures on the pores of the biochar was investigated by using scanning electron microscopy with energy-dispersive x-ray spectroscopy, X-ray diffraction, and Fourier-transform infrared spectroscopy. The characterization of the biochar shows mesoporous structures, as well as increased surface area and pore volume. The chemical composition has potassium at higher concentrations than other metals, while similar surface functional groups were found in the biochar, such as phenolic, aliphatic, conjugated quinones, and OH-phenolic. The thermal treatments applied to poultry litter generated samples with similar physical, chemical, and structural characteristics. Thus, the production of biochar by the farmer and its use as a soil conditioner can contribute to the reduction of agricultural pollution, management, and efficient disposal of residual biomass.

“…In the infrared spectrum of BSM, the characteristics peaks at 1,071 cm -1 and 1,726 cm -1 are assigned to epoxide rings and carbonyl groups, respectively. The characteristic absorption peaks of hydroxyl (O-H) and amine (N-H) stretching vibrations appears at 3,482 cm -1 and 3,728 cm -1 [9,17,19]. In the spectrum of LEVO-loaded BSM, the above identified functional groups shifted or reduced.…”

Manganese dioxide was laden hooked on biochar sourced from chicken feather to obtain a biochar-supported manganese dioxide (BSM) composite. In order to reduce the costs of acquisition and minimise the disposal of adsorbents, prepared BSM composite were employed in the sequestration of Levofloxacin (LEVO) from aqueous environment. The physico-chemical features and the adsorption mechanisms of prepared BSM, prior and after the adsorption of LEVO molecules were revealed by Scanning Electron Microscopy and Fourier Transform Infrared spectroscopy techniques. The influence of adsorption parameters including BSM dose, initial concentration, temperature and residence time were studied. The removal of LEVO was significantly influenced by all parameters. Equilibrium data has its fitness in the following order: Redlich-Peterson ˃ Langmuir ˃ Freundlich models. The maximum adsorption capacity of BSM for LEVO was 104.13 mg/g. The kinetic analysis indicates best fittings for pseudo-second-order model suggesting chemisorption as controlled mechanism. Besides, liquid film and intraparticle diffusion had a vital influence on the LEVO sequestration process. Exothermic and spontaneous nature of LEVO uptake by BSM was revealed by thermodynamic analysis. The findings suggested that prepared BSM show high sorption capacity, and recyclability potential towards separation of LEVO from contaminated pharmaceutical wastewater.

“…Cuixia et al [139] carried out the pyrolysis of chicken manure at varying process temperatures from 200 to 800 °C and evaluated the use of chicken manure bio-char (CMB) for the removal of lead. The adsorption capacity of lead ions is positively correlated with process temperature and the maximum adsorption capacity of 242.57 mg/g was obtained using CMB prepared during pyrolysis of chicken manure at 800 °C.…”

The slaughterhouse and poultry industry is possibly one of the fastest-growing sectors driven by the increasing demand in food availability. Subsequently, the wastes produced from the slaughterhouse and poultry industry are in huge quantities, which could be a promising resource for the recovery of value added products, and bioenergy production to minimize the dependence on fossil fuels. Furthermore, the wastes from slaughterhouses and poultry are a hub of pathogens that is capable of infecting humans and animals. This demands the emerging need for an effective and safe disposal method to reduce the spread of diseases following animal slaughtering. In light of that, the state of the production of slaughterhouse and poultry wastes was presented at first. Following this, the impact of solid waste exposure in terms of air, water, and soil pollution and the associated health challenges due to improper solid waste management practices were presented to highlight the importance of the topic. Secondly, the potency of these solid wastes and the various waste-to-energy technologies that have been employed for effective management and resource utilization of wastes generated from slaughterhouses and poultry were reviewed in detail. Finally, this review also highlights the opportunities and challenges associated with effective solid waste management, future requirements for the development of effective technologies for the recovery of value added products (like keratin, fibreboards), and biofuel production.
