“…Some of them have reported how properties of torrefied biomaterials change with pressure [22,23], temperature and time [24,25], or atmosphere [26,27]. Dissimilar feedstocks such as wood chips [28,29], corn stalks [30,31], sewage sludge [32,33], and industrial wastes [34,35] have been applied, and followed by studying solid and energy yields, or calorific values. In all the above mentioned studies it was confirmed that the fuel properties of torrefied biomass were better than raw biomass.…”

“…Thermogravimetric analysis (TGA) is considered to be the most useful technique to define kinetics reactions for lignocellulosic biomass [28], as it is a rapid and inexpensive method for determining the physicochemical properties of biomasses, based on measuring the rate of weight loss as a function of temperature and time [43]. Two different types of methods can be applied from TGA to study kinetics mechanisms: model-fitting methods and model-free methods.…”

The torrefaction process upgrades biomass characteristics and produces solid biofuels that are coal-like in their properties. Kinetics analysis is important for the determination of the appropriate torrefaction condition to obtain the best utilization possible. In this study, the kinetics (Friedman (FR) and Kissinger–Akahira–Sunose (KAS) isoconversional methods) of two final products of lignocellulosic feedstocks, miscanthus (Miscanthus x giganteus) and hops waste (Humulus Lupulus), were studied under different heating rates (10, 15, and 20 °C/min) using thermogravimetry (TGA) under air atmosphere as the main method to investigate. The results of proximate and ultimate analysis showed an increase in HHV values, carbon content, and fixed carbon content, followed by a decrease in the VM and O/C ratios for both torrefied biomasses, respectively. FTIR spectra confirmed the chemical changes during the torrefaction process, and they corresponded to the TGA results. The average Eα for torrefied miscanthus increased with the conversion degree for both models (25–254 kJ/mol for FR and 47–239 kJ/mol for the KAS model). The same trend was noticed for the torrefied hops waste samples; the values were within the range of 14–224 kJ/mol and 60–221 kJ/mol for the FR and KAS models, respectively. Overall, the Ea values for the torrefied biomass were much higher than for raw biomass, which was due to the different compositions of the torrefied material. Therefore, it can be concluded that both torrefied products can be used as a potential biofuel source.

“…Total nitrogen was determined by the Kjeldahl method [14]. The C/N ratio was determined with the formula C/N = 0.52 (100−a)/N, where a is ash content (%), 0.52 is carbon content coefficient [15,16], and N is total nitrogen content (%).…”

Pleurotus eryngii is a new entrant into commercial cultivation, hence the need to optimize factors that affect yield and biological efficiency (BE) during cultivation. Two local isolates/strains, IBK 2032 and 2033, and a commercial strain, 2600, were studied for commercial cultivation suitability. Strain 2032 reached pinning 37.3 ± 0.9 days after inoculation, followed by 2033, 43.2 ± 1.2, and the last 2600 was 57.4 ± 4.8 days. Strains 2032, 2033, and 2600 attained the harvesting stage at 49.2 ± 6.1, 53.1 ± 3.2, and 68 ± 3.4 days, respectively, after inoculation. In fruiting body (FB) yield and BE, strain 2032 had 603.5 ± 9.2 g and 47.5% ± 6.6%, respectively, per bag; strain 2600 gave the least yield and BE. Strains 2032 and 2033 showed individual FB weight distribution values that displayed right-sided asymmetry, with coefficients of 1.73 and 1.31, respectively, whereas strain 2600 had a coefficient of 1.09. The cap diameter was largest in strain 2033 (59.7 mm), and the least (46.4 mm) was in strain 2600. Strain 2032 had the best results among all parameters measured, except for FB height. The results indicated yield, BE, and FB morphological characteristics in the local isolates that could support longer shelf life and consumer appeal.

“…The precursors that were used in this paper for the preparation of activated carbon materials are date-palm leafleaf stalks ( Phoenix daclylifera L.) and black alder cone-like flowers ( Alnus glutinosa L.). In the available literature, there are papers where both precursors were characterized using different techniques [ 11 , 12 , 13 ]. However, there are no data on obtaining activated carbons from these precursors and their specific applications on the treatment of real contaminated waters.…”

The impact of urbanization and modern agricultural practice has led to accelerated eutrophication of aquatic ecosystems, which has resulted in the massive development of cyanobacteria. Very often, in response to various environmental influences, cyanobacteria produce potentially carcinogenic cyanotoxins. Long-term human exposure to cyanotoxins, through drinking water as well as recreational water (i.e., rivers or lakes), can cause serious health consequences. In order to overcome this problem, this paper presents the synthesis of completely new activated carbons and their potential application in contaminated water treatment. The synthesis and characterization of new active carbon materials obtained from waste biomass, date-palm leaf stalks (P_AC) and black alder cone-like flowers (A_AC) of reliable physical and chemical characteristics were presented in this article. The commercial activated carbon (C_AC) was also examined for the purpose of comparisons with the obtained materials. The detailed characterization of materials was carried out by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), low-temperature N2 physisorption, and Field emission scanning electron microscopy (FESEM). Preliminary analyzes of the adsorption capacities of all activated carbon materials were conducted on water samples from Aleksandrovac Lake (Southern part of Serbia), as a eutrophic lake, in order to remove Cyanobacteria from water. The results after 24 h of filtration showed removal efficiencies for P_AC, A_AC, and C_AC of 99.99%, 99.99% and 89.79%, respectively.
