AB  - The concept of a bio-based economy has been adopted by many advanced countries around
the world, and thermochemical conversion of waste biomass is recognized as the most effective
approach to achieve this objective. Recent studies indicate that hydrothermal carbonization (HTC)
is a promising method for the conversion of waste biomass towards novel carbonaceous materials
known as hydrochars. This cost-effective and eco-friendly process operates at moderate temperatures
(180–280 ◦C) and uses water as a reaction medium. HTC has been successfully applied to a wide
range of waste materials, including lignocellulose biomass, sewage sludge, algae, and municipal solid
waste, generating desirable carbonaceous products. This review provides an overview of the key
HTC process parameters, as well as the physical and chemical properties of the obtained hydrochar.
It also explores potential applications of produced materials and highlights the modification and
functionalization techniques that can transform these materials into game-changing solutions for a
sustainable future.

AB  - The corn cob was investigated as available agrowaste material for the production of potential efficient material for heavy
metals removal. The hydrothermal carbonization (HTC) technology is one of the appropriate methods for biomass
transformation into high-value carbonaceous products than can be utilized as adsorbents. In this study, modified pyrohydrochar
derived from corn cob (MCC) was effectively prepared by modification with Mg-Fe solution and pyrolysis.
This material was used for Pb ions removal from aqueous solutions. The effect of solution pH, contact time and initial Pb
concentration were examined in batch system. The achieved results revealed that the most effective Pb adsorption take
place at pH 5. The experimental results were fitted to Langmuir, Freundlich, Sips and Redlich-Peterson isotherm models.
The best data fit was achieved with the Sips isotherm model with maximum adsorption capacity for Pb removal of 214.9
mg/g. Additionally, the experimentally results from kinetic study were fitted by pseudo-first and pseudo-second order
models. According to kinetic parameters, the Pb removal using MCC follows pseudo-second order model, which assumes
that chemical interaction between Pb ions and functional groups on the MCC surface was involved in metal adsorption.
According to data from this investigation and in comparisons to other adsorbents can be concluded that investigated
material can be used as potential suitable adsorbent of Pb from aqueous solutions.

AB  - The accumulation of mine tailings in the mining area of Majdanpek represents a serious environmental problem. A strong impetus for the development of sustainable methods for the recovery of metals from mine tailings is given by the importance of heavy metal recovery and the economic benefits of precious and base metals. Currently, researchers are working to develop metals recovery from tailings through bioleaching, which is a more sustainable method compared to traditional metallurgical methods. Biotechnologies for leaching heavy metals from old flotation tailings (Majdanpek, Serbia) with fungus Aspergillus niger (A. niger) are discussed in this paper. The subject of this research is iron ions, since the tailings are the richest in this metal. With a simple bioleaching process, which is based on the cultivation of A. niger in the basic growth medium and then challenging it with tailings, 5% iron was released in 35 days. The transformation of mine tailings morphology was also confirmed by optical microscopy. Processes by which A. niger extracts metals from
tailings include acidolysis, complexation, alkaloysis and biosorption. Also, in addition to metabolites, these fungi produce spores and mycelium that can destroy material and transform it to the soil. Given that Serbia is abundant with agricultural
waste, as well as waste from the food industry, in future studies cheap waste should be used as an energy input source for A. niger and transformation of tailings.

AB  - In this study, Paulownia tree leaves hydrochars (PL-HTCs) were used as potential adsorbents for
Zn(II), Cd(II) and Mn(II) ions from aqueous solution and their efficiency was investigated. The
preliminary adsorption results showed that hydrochars had better affinity for Cd(II) than for Zn(II)
and Mn(II) ions removal. In order to improve adsorption capacity, hydrochar obtained at 220°C were
activated with NaOH and further investigated only for Cd(II) removal. Alkali activated hydrochar
(AH-220) has significantly better efficiency (q=24.05 mg/g, E=52.57%) in removing Cd(II) ions than
hydrochar before modification. Adsorption kinetic studies showed that Cd(II) ions sorption at AH-220
surface followed the pseudo-second-order model. This implies that the adsorption process was mostly
controlled by the chemical binding.

AB  - In this study, hydrothermal carbonization (HTC) at five temperatures (180, 200, 220, 240,
and 260  C) was applied to transform Paulownia leaves (PL) into a carbonaceous sorbent of Pb(II)
from aqueous solutions. To enhance the adsorption efficiency of the obtained hydrochar (PH),
subsequent alkali activation was performed using NaOH. Preliminary results of the Pb(II) adsorption
(CPb = 200 mg/L) showed removal coefficients after 48 h of 73.44 mg/g, 82.37 mg/g, and 110.9 mg/g
for PL, PH-220, and MPH-220, respectively. The selected hydrochar (PH-220) and modified hydrochar
(MPH-220) were further investigated by scanning electron microscopy (SEM) and Fourier transform
infrared spectroscopy (FTIR). The results revealed that alkali treatment changed the hydrochar
structure and, thus, improved its adsorption performance. The kinetic parameters showed that
the Pb(II) sorption onto MPH-220 followed a pseudo-second-order model, while the intra-particle
diffusion went through two simultaneous stages. The Langmuir isotherm model best described the
experimental data and indicated the value of 174.75 mg Pb(II)/g as the maximum adsorption capacity.
The two possible mechanisms of Pb(II) binding were complexation and/or Pb-  electron interaction.
The obtained results indicate the great potential of MPH-220 for Pb(II) removal from aqueous media
and its potential utilization as an effective adsorbent for wastewater purification.

In order to improve the adsorption capacity this material was modified with selected deep eutectic solvent (DES). Changes in the structure of the native and modified samples were examined using the SEM analysis. The efficiency of the adsorption of heavy metal ions from a multimetal solution was tested on the modified oat straw. The maximum obtained capacities of lead, copper and zinc ions were 77mg/g, 29.5mg/g and 44.1mg/g, respectively. The obtained results showed that adsorption follows pseudo-second-order kinetics model that imply chemisorption as a rate controlling step.

AB  - This study examined Mg/Fe-pyro-hydrochar produced from grape pomace as potential sorbent for Cu2+
ions. Obtained results show that the Mg/Fe-modification increases the adsorption capacity for five times.
To evaluate the effectiveness of produced sorbent, Langmuir, Freundlich, Sips and Redlich-Peterson
isotherm models were applied to batch adsorption results. According to applied models Cu2+ adsorption at
equilibrium fitted the Sips isotherm model, with a maximum achieved capacity of 75 mg/g. Spectroscopic
analysis reveal that oxygenated active sites and aromatic groups on pyro-hydrochar surface participate in
Cu2+ions binding. In general, preliminary findings from this paper offers perspective to effective utilization
of waste biomass as an efficient adsorbents for Cu2+ ions removal.

AB  - Water pollution caused by industrial effluents without prior purification treatment represents one of the serious environmental concerns in contemporary times. Lately, due to its surface characteristics, pronounced chemical reactivity, and efficient regeneration ability, hydrochar obtained by hydrothermal carbonization of waste biomass has been explored as sustainable adsorbents for the removal of different pollutants. Besides, potential disadvantages of this material, such as low specific surface area and porosity, are easily overcome by surface modifications and composites synthesis. Previous reported studies have shown that chemical methods that include hydrogen peroxide or alkalis treatment, and incorporation of metals onto hydrochar surface can significantly improve its adsorption performances. Within this study, the potential application of hydrochars from different precursors and its composites as efficient sorbents of organic dyes and heavy metals from aqueous solutions will be discussed. Special attention will be directed towards structural changes caused by modification, achieved adsorption capacities and potential adsorption mechanisms. In general, the valorisation of hydrochar as a polluter sorbent solves the problems of sustainable and efficient material for purification and disposal of waste with permanent consequences to the environment.

AB  - This article presents studies, whose main goal was to minimize food waste. To achieve this goal, it is necessary to expand the scope of their application, for example, for the purification of polluted water from heavy metals. Millions of tons of waste from the fruit and vegetable industry, including pomace of apples and beetroots, are thrown into landfills, posing a danger to the environment. In order to solve the problems with the disposal of these wastes, the authors investigated their sorption potential for the removal of lead from wastewater. The sorbents, dried apple (AP), and beetroots (BR) pomaces were characterized by various methods (study of composition, zeta potential, FTIR-ATR, and SEM-EDX). Various models of sorption kinetics and sorption isotherms were analyzed. Kinetical studies under optimal conditions showed that the sorption process occurs through complexation and ion exchange and the determining stage limiting the rate of sorption is the diffusion of lead ions in the sorbent. The maximum sorption capacity was 31.7 and 79.8 mg/g for AP and BR, respectively. The thermodynamic data revealed the spontaneous sorption of lead ions by sorbents. The temperature rise contributes to the sorption increase by the AP sorbent, while for the BR sorbent, the opposite effect is observed. The obtained results showed that apple and beetroots pomaces can serve as effective renewable materials for the preparation of sorbents, contributing to the solution of complex environmental problems.

AB  - Mushroom cultivation and consumption have been steadily increasing in recent decades, however, after mushroom cultivation, a large amount of by-products, known as spent mushroom substrate (SMS), are left behind in open dumps where about 5 kg of SMS are generated for every kilogram of mushroom (Agaricus bisporus). Around 51 million tons of SMS are produced in the world every year. Hydrothermal carbonization (HTC) is a promising technology for the conversion of SMS into a rich carbon product, hydrochar. The hydrochar was synthesized in a hydrothermal reactor at a temperature of 180 °C for a reaction time of 1 h. The characterization of the SMS and its chars was done by FTIR, SEM, and TGA analysis. The FTIR analysis showed that aromatic and oxygen-rich functional groups are dominant on the hydrochar surface. It was noticed that the hydrochar had more visible pores compared to the SMS. The porous structure and oxygen functional groups of hydrochar probably influenced the improvement of adsorption performance, since the adsorption capacity of SMS for Cd2+ ions was 28 mg L-1, while for hydrochar it was 92 mg L-1. On the other hand, the thermal kinetic analysis has shown that hydrothermally treatment upgrades the combustion behavior of hydrochar. The kinetic parameters were determined by Kissinger and Ozawa methods. The hydrochar had notably lower activation energy compared to the SMS, which means that this hydrochar requires a smaller amount of energy to start combustion. The preliminary results show that HTC effectively transforms SMS into alternative solid biofuel and eco-friendly sorbent.

AB  - In the proposed study, agro-waste biomass oat straw (OS) was considered a potential adsorbent for Cu(II), Zn(II), and Se(IV) removal from aqueous solutions. In order to obtain material with better adsorption abilities, the OS was modified by a deep eutectic solvent (DES). Structural changes caused by the applied modification route were considered by pHpzc, SEM, FTIR, and DSC/TG analysis. These methods discovered that lignocellulosic biomass degradation and material functionalization were achieved by DES treatment. Preliminary adsorption tests showed an over fourfold increase in capacity upon modification. The kinetic parameters implied that adsorption on modified material followed the pseudo-second-order kinetic model. Different isotherm models were applied to experimental data, while the Sips isotherm model best describes the equilibrium of the adsorption process on the tested modified material. According to this isotherm model, the maximum achieved adsorption capacities of Cu(II), Zn(II), and Se(IV) were 48.21, 55.06, and 87.85 mg/g, respectively. The summarized experimental results revealed that the adsorption process of selected cations on modified OS was predominantly caused by chemisorption, while, in addition to chemisorption, electrostatic forces were also responsible for Se(IV) removal. Desorption test showed that the prepared material could be reused for at least 3 cycles, with minimal efficiency loss. Briefly, this study reinforces that DES-modified agro-waste biomass could be used as a promising adsorbent for cations and oxyanions from wastewater.

AB  - In this study, Mg-based pyro-hydrochars derived from waste grape pomace (Mg-GP), corn cob (Mg-CC), and Miscanthus x giganteus (Mg-MIS) were successfully prepared applying one-step hydrothermal carbonization followed by pyrolysis. The structural characteristics and surface analysis of the prepared materials were characterized by various techniques, while its adsorption ability was examined through remediation of methylene blue (MB) under batch adsorption experiments. The obtained results revealed that pyro-hydrochars are highly effective adsorbents of MB with achieved capacities of 289.65 mg g(-1), 262.30 mg g(-1), and 232.48 mg g(-1) for Mg-GP, Mg-CC and Mg-MIS, respectively. The binding of MB to the surface on either of the tested material was achieved by a complex mechanism that unifies electro-static interaction, hydrogen bonding, pi-pi interaction, surface complexation, and ion-exchange mechanism. The kinetic study display that the adsorption process onto used Mg-doped pyro-hydrochars is favorable and follows pseudo-second order kinetics, while the isotherm equilibriums were determined by Sips isotherm model. Tested materials can be effectively reused for at least 3 cycles, with minimal loss of efficiency. Overall, findings from this work promote Mg-doped pyro-hydrochars form different precursors as promising, sustainable, and efficient adsorbents of MB from polluted wastewaters.

AB  - In this study, the adsorption capacity of Pb2+ removal from aqueous solution was examined by hydrochar of the spent mushroom substrate. In order to improve the adsorption capacity, hydrochar was previously activated with 2M KOH. The obtained results demonstrated that alkally activation increased the sorption capacity from 36 mg g-1 to 74 mg g-1. Structural characterization of activated and inactivated hydrochars were performed by FTIR analysis. Toward to obtained results of FTIR analysis, the increased of the oxygen functional groups (OFG) in activated hydrochars was perceived, which is contributed to the increase in the adsorption capacity of this carbonized material. Results indicated that spent mushroom substrate can be converted into hydrochar as a perspective sorbent for removal of Pb2+.

abstract = "In this study, the adsorption capacity of Pb2+ removal from aqueous solution was examined by hydrochar of the spent mushroom substrate. In order to improve the adsorption capacity, hydrochar was previously activated with 2M KOH. The obtained results demonstrated that alkally activation increased the sorption capacity from 36 mg g-1 to 74 mg g-1. Structural characterization of activated and inactivated hydrochars were performed by FTIR analysis. Toward to obtained results of FTIR analysis, the increased of the oxygen functional groups (OFG) in activated hydrochars was perceived, which is contributed to the increase in the adsorption capacity of this carbonized material. Results indicated that spent mushroom substrate can be converted into hydrochar as a perspective sorbent for removal of Pb2+.",

AB  - Poslednjih decenija, masovno iskorišćenje i eksploatacija fosilnih goriva dovodi do brojnih negatinih uticaja na životnu sredinu. Iz ovog razloga se se sve više teži ka implementaciji tehnologija koje bi omogućile proizvodnju biogoriva iz obnovljivih izvora. Hidrotermalna karbonizacija (HTC) je prepoznata kao jedna od visoko efikasnih i perspektivnih tehnologija za valorizaciju otpadne biomase kroz proizvodnju ugljeničnih materijala (hidročadi) široke upotrebne vrednosti. U okviru ovog rada komina grožđa je podvrgnuta HTC tretmanu na različitim temperaturama i izvršeno je ispitivanje gorivnih karakteristika dobijenih hidročadi. Rezultati su pokazali da sa porastom temperature karbonizacije rastu gornja i donja toplotna moć (od 20,40 do 26,78 MJ/kg i od 18,80 do 25,36 MJ/kg, redom), kao i energetska gustina u dobijenim hidročadima, dok istvoremeno atomski O/C i H/C odnosi, isparljive materije (sa 75,50 % na 61,22 %), i energetski prinos opadaju. Preliminarni rezultati ove studije sugerišu da dobijene hidroćadi pokazuju poboljšana gorivna svojstva u odnosu na kominu grožđa i da konverzija primenom HTC-a može biti korisna metoda za upravljanje otpadom i povrat energije iz otpadne biomase.

AB  - Background: Over the years, the mass utilization of fossil fuels causes numerous harmful effects on the
environment. Therefore, great attention is paid to the implementation of technologies that would enable
the production of biofuels from renewable sources. Hydrothermal carbonization (HTC) is recognized as
one of the highly efficient and promising technologies for the production of value-added materials from
wet and waste biomass.
Objective: The main goal of this study is the valorization of waste grape pomace (GP) using HTC
technology. Emphasis will be placed on the examination of the influence of process temperature on the
selected structural and fuel characteristics of the obtained solids (hydrochars).
Methods: For the preparation of hydrochars 10g of GP and 150 mL of ultrapure water were carbonized
using laboratory autoclave (Carl Roth, Model II). Carbonization was carried out at 180, 200, 220, 240
and 260 °C within 1 h. Obtained hydrochars (H180, H200, H220, H240 and H260) were separated from
process water, rinsed and dried to constant weight. Elemental content of solid` (C, H, N, S) was performed
using Vario EL III; C, H, N, S/O Elemental Analyzer, while O contents and HHV were calculated.
Results: Obtained results showed that carbonization temperature significantly influences the structural
characteristics of produced hydrochars. The C content was increased from 48.9% (GP), up to 69.9%
(H260) with the temperature increase, while the content of other elements was decreased. Observed
changes in elemental composition are caused by dehydration and decarboxylation of biomass during the
HTC process. Additionally, the HHV of GP was 21.64 MJ/kg, while it was increased upon carbonization
up to 26.78 MJ/kg (H260).
Conclusion: Preliminary results of this study determined that implementation of HTC technology
improves fuel characteristics of GP and may represent a suitable route for the utilization of waste
biomass.

AB  - Zeolites are inorganic, crystalline aluminosilicates that nowadays has been used as
adsorbents, catalysts and carriers of catalytically activated substances, due to the small size
of their pores, large internal surface, and well-defined chemical composition. In this paper,
the modification of beta zeolite using (3-aminopropyl)-triethoxysilane (APTES) was
investigated. The results of the Fourier transform infrared spectroscopy and
thermogravimetric analysis confirmed the presence of amino groups derived from APTES
onto the modified zeolite surface. APTES-enriched zeolite was further used as an adsorbent
of silver ions from aqueous solutions. The obtained results reveal that a zeolite after
modification exhibited significantly better adsorption efficiency (97%) in comparison to the
unmodified (37%). The kinetic data follows the pseudo-second-order model which
indicates a chemical interaction between silver ions and functional amino groups on the
surface of the silanizedbeta zeolite. Ag-APTES enriched beta zeolite also was studied as
anantibacterial agent toward the pathogenic bacteria Gram-negative Escherichia coliDSM

AB  - A low-cost waste biomass generated from a food industry, apricot shells, was subjected to alkali modification in order to compare morphology, crystalline structure and thermal stability of native and modified biomass, accompanied by their cellulose-rich fractions. The surface morphology and structure of compared samples were analysed by the scanning electron microscopy (SEM) and mercury porosimetry. Furthermore, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermal analysis (TG/DTA) were applied. The results have shown that after alkaline treatment, inter- and intra-particle porosity in the material rises, resulting in increase of the total surface area. The XRD diffractograms showed that crystallinity index increased together with crystallite size, suggesting that modified sample has more ordered crystalline structure than native sample (also confirmed by the FTIR analysis). Although the cellulose-rich fraction extracted from the alkali-modified sample showed higher thermal stability, the overall thermal analysis revealed that alkali-modified biomass has lower thermal stability than the native sample. This indicates that this type of modification will improve the fuel properties of this lignocellulosic biomass and imply its possible application in energy recovery process.

AB  - The Paulownia leaves (PL) was used for the first time as feedstock for the potential production of novel carbon-rich materials applying hydrothermal carbonization (HTC) technology. The HTC is one of the suitable methods for converting biomass into high-value carbonaceous products that could replace existing fossil fuels or be used for some other application. In this study, hydrochars of PL were obtained at five different temperatures (180, 200, 220, 240, and 260 degrees C), and the influence of temperature on hydrochar structures was analyzed. Physicochemical composition, structural, and combustion properties were estimated for hydrochar efficient characterization. The results showed that tested hydrochars had lower moisture, volatiles, oxygen, and sulfur content compared to PL biomass. Also, the HTC process increases carbon content and created high-energy C-C bond structures in hydrochars which improved fuel ratio (FR), energy density (ED), higher heat value (HHV), and lower heating value (LHV). However, hydrochar mass yields were significantly low, which affected the lower heating value (EY). The spectroscopic and thermal analysis confirmed the formation of new aromatic structures in hydrochars and enhancement of their thermal stability and combustion ability, respectively. Before hydrochar practice, in order to enhance their mass yields, it is necessary to further analyze the influence of the HTC parameters or hydrothermal co-carbonization with other biomass should be taken into concern. The results showed that HTC could be an efficient method to improve the combustion properties of PL biomass.

AB  - In this study, raw corn silk was considered for the removal of cadmium ions from aqueous solutions. In order to improve adsorption characteristics, the KOH treatment was applied as a route to obtain modified materials. Both materials before and after metal adsorption were characterized by pH(PZC), SEM-EDX and FTIR analysis. SEM images and FTIR spectra revealed that alkali modification caused some structural changes that could improve the adsorption properties of the investigated material. The experimental results and the ion-exchange study revealed that the biosorption process of cadmium ions on to raw and modified corn silk was caused predominantly by the ion-exchange mechanism, followed by chemisorption. The kinetic parameters implied that there are three stages in the biosorption process. In addition, the cadmium adsorption on both materials is very fast and is followed by the pseudo-second-order kinetic model. The experimental results were fitted by two and three parameter isotherm models, while the Sips isotherm model best describes the biosorption process on both materials. According to the Sips isotherm model, the maximum adsorption capacity of cadmium adsorbed on modified materials was 49.06 mg g(-1), which is 2.23 times greater in comparison to the raw material (21.96 mg g(-1)). Furthermore, the mechanisms of cadmium adsorption onto the investigated materials are summarized in order to better understand the modification influence on the adsorption properties of corn silk. In order to examine reusability of the investigated material, diluted nitric acid was used for regeneration. A desorption study was performed in three adsorption-desorption cycles. A high desorption efficiency (>85%) indicated that MCS after Cd adsorption can be efficiently recovered and reused for a new adsorption cycle.

In recent decades, the massive exploitation of fossil fuels, with a detrimental impact on the environment, caused a growing demand for the production of energies from renewable sources. One of the researchers' solutions was the application of waste biomass, but there are many disadvantages of its direct utilization, that include high moisture content, low energy content, high volatiles content, etc. In order to overcome these disadvantages, attention has been focused toward development of technologies for conversion of biomass into a multi-functional products. Hydrothermal carbonization (HTC) has recognized as highly effective technology for production of carbon rich material, hydrochar, from wet and waste biomass. Hydrochar possess a great potential for application as an energy source, for environmental protection, in agriculture. In this paper, three selected biomasses (corn cob (CC), Paulownia leafs (PL) and olive pomace (OP)) were hydrothermally carbonized at different temperatures (180, 220 and 260°C). The main goal of this study was to examine the influence of temperature on the structure and fuel characteristics of the obtained products and to compare it with the precursor. The results showed that the solid yiels decreases significantly with increasing temperature in all samples. On the other hand, C content increase upon temperature increment and reach the highest values in hydrochars obtained at 260°C (69.30% for CC, 64.54% for PL and 70.97% for OP). Also, a decrease in O/C and H/C atomic ratios with increasing temperature was observed. The results are shown in the Van Krevelen diagram, which reveals the transformation of precursors during carbonization from the biomass to the lignite region. Furthermore, with decrease of O/C and H/C ratio, higher heating value (HHV) was increasing and reaches the maximum values for hydrochars prepared at 260°C (27.33 MJ/kg for CC, 28.06 MJ/kg for PL and 30.55 MJ/kg for OP). The same trend is noticeable with ED contents. Also, the content of volatile matter (VM) was determined in all samples. VM decreases (from 90.45 to 55.42% for CC, from 76.70 to 62.10% for PL, from 82.86 to 66.77% for OP) with temperature contributes to less evaporation and pollutant emission during direct combustion. According to results, can be concluded that temperature has a great influence on the structure and characteristics of the obtained products, that dehydration and decarboxylation during HTC provoke intensive biomass carbonization and that hydrochars obtained at higher temperatures have significantly enhanced fuel properties and less volatiles compared to the biomass."
