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  - 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.

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

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.

A flurry of activity has sprung up around this carbon-based material, produced from biomass, following its use in water treatment, energy production and animal husbandry. In any new industry, process and product development, as well as feasibility studies, are very important for the product to come to market. This is especially true when it comes to biochar. Besides being in its infancy as an industry, biochar itself presents a number of challenges that make various tests necessary. Many properties affect the quality and performance of biochar products (pore size, cation exchange, electro- conductivity...) and will most likely vary depending on the starting material and the method of obtaining. Biochar can be made from a very long list of biomass materials. Although the above creates opportunities for industries that abound with highly adaptable products, it can still make biochar unpredictable, given that each starting material affects the characteristics of the final products differently.

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  - The objective of this study was to investigate the transport behavior of two organic and persistent contaminants (alachlor and pentachlorobenzene) on Danube alluvial sediment in the absence and in the presence of microbially inoculated biochar produced at 400 degrees C and three hydrochars produced at 180, 200, and 220 degrees C. Stainless steel columns were used for the sorption experiments in nonequilibrium conditions. Obtained results were modeled using the advective-dispersive equation under nonequilibrium conditions. Transport of these compounds through the alluvial sediment column showed that the retention time increased with increasing molecular hydrophobicity. Inoculated biochar increases the retardation of both compounds: twofold for pentachlorobenzene compared with alachlor as a consequence of a higher hydrophobicity. Obtained results indicate that the highest biodegradation coefficient was observed for pentachlorobenzene (lambda = 10) in alluvial sediment with addition of an inoculated hydrochar, which is assumed to be a consequence of biosorption. Moreover, all experiments on the columns indicate that the addition of inoculated chars yields a significantly higher R-d coefficient for pentachlorobenzene than for alachlor. Bacterial counts increased in all of the column experiments, which indicates the successful adaptation of microorganisms to experimental conditions and their potential for the removal of a large number of organic pollutants. Thus, addition of inoculated chars to contaminated sediments has the potential as a remediation technique to inhibit the leaching of pollutants to groundwaters.

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.

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  - A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2 center dot 5H(2)O activation and pyrolysis. The characterisation of chars before and after modifications was done by scanning electron microscope (SEM), Brunauer-Emmett- Teller (BET) and Fourier transform infrared (FTIR). Batch experiments were performed to examine Ca-PHC's sorption properties and binding mechanisms to selected metal ions. The maximum sorption capacities of Ca-PHC for Pb2+ and Cd2+ were 297 mg g(-1) , and 131 mg g(-1) respectively. The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudosecond kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation-pi interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.

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."

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."",

AB  - In this study, the minimization of heavy metal pollution was investigated. Accordingly, potential of corn silk as biosorbent of Pb, Zn and Cu from multimetal solution was considered in batch and fixed-bed column experiments. Structural changes of corn silk before and after heavy metal removal were determined using SEM-EDX and FTIR analyses. For investigation of biosorption performance the Langmuir and Freundlich isotherm models were applied at batch experimental results. Fast biosorption process and high adsorption capacity (0.382; 0.200 and 0.171 mmol g-1 for Pb2+, Cu2+ and Zn2+, respectively) confirmed that the corn silk is suitable for heavy metals removal. In order to produce a novel and improved column package for fixed-column bed study implementation, the corn silk was immobilized with alginate. The fixed-bed column was saturated with Pb-Cu-Zn multimetal solution. The breaktrought time is 95, 100 and 90 min for Pb2+, Cu2+ and Zn2+ respectively, where 87.5, 81.9 and 95.5% Pb2+, Cu2+ and Zn2+ was removed, respectively. Desorption sudy was performed in HNO3 (p.a.) solution where high desorption efficiency (>94%) confirmed that imobilized corn silk can be used as alternative material for metal adsorption and could be applied in purification systems.

AB  - Within this study, the potential application of grape pomace hydrochar as a potential adsorbent of lead ions from aqueous
solutions will be investigated for the first time. For preparation of hydrochar, the grape pomace was hydrothermally carbonized in aqueous medium at 220 °C within 1 h. Obtained material was further modified with Mg and Fe salts in order to improve its adsorption properties. Preliminary adsorption results showed that the modified hydrochar exhibited significantly higher adsorption capacity (139.5 mg g-1) compared to the unmodified one (27.8 mg g-1). Further examination of the effects of different adsorption parameters (initial pH value and contact time) using modified and unmodified hydrochar, defined
their optimum values for the most effective lead removal. The obtained results showed that the most efficient removal of lead ions occurs in solutions with pH 5. Furthermore, the examination of the influence of time on the adsorption processdemonstrated that in the beginning the adsorption takes place quickly. The reason for this is the large number of availableactive centres on the hydrochar surface that can bind lead ions. However, as the number of these centres is occupied by a longer contact time, the binding rate decreases and after 240 minutes the equilibrium is reached. Kinetic models of pseudo-first and pseudo-second order were applied to the results of the influence of contact time. The kinetic study implied that the removal of lead ions on modified hydrochars follows pseudo-second order model. This model assumes a chemical interaction between
lead ions and groups on the surface of hydrochar as the main binding mechanism. Based on the above it can be concluded thatthe hydrothermal carbonization is very efficient technology for conversion of waste biomass into highly valuable products. In order to examine in more detail the binding mechanism and the process of metal adsorption using modified hydrochars, additional analyzes will be part of our future research.

AB  - Biosorption is evolving as a potential alternative to the
existing conventional technologies for the removal and/
or recovery of pollutants from aqueous solutions. The
present work investigates the possible application of
waste biomass Myriophyllum spicatum (Ms) in removing
contaminants, evaluating equilibrium through isotherms
of selected heavy metals: lead, copper, and
cadmium. As a heavy metal biosorbent, Ms was immobilized
in alginate beads (Ms: Alginate 2:1). Applied
biosorbent, MsA, was characterized by scanning electron
microscopy with energy dispersive X-ray spectroscopy
(SEM–EDX) and Fourier transform infrared spectroscopy
(FT-IR). Experimental results were fitted (nonlinear)
by six isotherm models: Langmuir, Freundlich,
Sips, Redlich and Peterson, Toth, and Temkin. For
lead(II) ion removal, fitting follows the following
sequence, F ≈ R-P > S > To > L > Te, while for copper(II)
and cadmium(II) ions are as follows: R-P > To ≈ Te ≈
L > S > F and R-P > L > To > S > F > Te, respectively. TOC
analyses revealed that M. spicatum releases 35.04 mg/L
of total organic content while immobilized sample, MsA,
only 6.81 mg/L. Finally, this biosorbent was tested on a sample of real wastewater from a coal-fired thermal
power plant complex TPP Kostolac (operated by PE
“Electric Power Industry of Serbia”). The results indicate
that using immobilized aquatic weed M. spicatum as
a biosorbent has a high potential for heavy metal wastewater
treatment applications.

AB  - Growing industrial activities generate huge amounts of waste biomass worldwide annually, which are, most often, improperly disposed, representing resource lost and secondary pollution sources. Many recent investigations have shown that this kind of biomass material can be reused as high quality sorbent, with certain modifications which would improve separation process. Having this in mind, we have investigated application of two biowaste materials-lignocellulosic waste of peach stones (Prunus Persica L) – IPS and invasive aquatic weed (Myriophyllum spicatum) - MsA, both immobilized in sodium alginate, as lead sorbents. For kinetic investigations, both sorbents were used to remove Pb2+ ions from synthetic solutions (batch reaction system with stirring), under defined operational parameters. Obtained data were modelled using nonlinear form of three most common kinetic models.

abstract = "Growing industrial activities generate huge amounts of waste biomass worldwide annually, which are, most often, improperly disposed, representing resource lost and secondary pollution sources. Many recent investigations have shown that this kind of biomass material can be reused as high quality sorbent, with certain modifications which would improve separation process. Having this in mind, we have investigated application of two biowaste materials-lignocellulosic waste of peach stones (Prunus Persica L) – IPS and invasive aquatic weed (Myriophyllum spicatum) - MsA, both immobilized in sodium alginate, as lead sorbents. For kinetic investigations, both sorbents were used to remove Pb2+ ions from synthetic solutions (batch reaction system with stirring), under defined operational parameters. Obtained data were modelled using nonlinear form of three most common kinetic models.",
