“…Costs also vary depending on whether the sorbent is made from by-products of existing industries or is formed from chemically pure raw materials; for example, fly ash-based sorbents are typically produced at low cost. Thus, assessment of the cost of adsorbents is critical to selecting a suitable material for water treatment [ 116 , 117 , 118 ].…”

Zeolites and mesoporous silica materials are effective adsorbents that can be useful for the removal of various pharmaceuticals including non-steroidal anti-inflammatory drugs and antibiotics from low-quality water. This paper summarizes the properties and basic characteristics of zeolites and mesoporous silica materials and reviews the recent studies on the efficacy of the adsorption of selected non-steroidal medicinal products and antibiotics by these adsorbents to assess the potential opportunities and challenges of using them in water treatment. It was found that the adsorption capacity of sorbents with high silica content is related to their surface hydrophobicity (hydrophilicity) and structural features, such as micropore volume and pore size, as well as the properties of the studied medicinal products. This review can be of help to scientists to develop an effective strategy for reducing the amount of these two groups of pharmaceuticals in wastewater.

“…Another conventional process such as the physical and chemical activation of the biochar also allows for obtaining substantial improvements in the material properties that favor the removal of pharmaceuticals and personal care products [113]. Thus, steam and phosphoric acid can activate the surface of bagasse biochar at high temperature, creating many holes on the surface, thereby increasing the adsorption of ibuprofen [114]. In addition, this biochar presented reusability potential by ibuprofen desorbing with methanol, but after four adsorption/desorption cycles, the removal percentage decreased by around 30%.…”

In this age, a key target for enhancing the competitiveness of the chemical, environmental and biotechnology industries is to manufacture high-value products more efficiently and especially with significantly reduced environmental impact. Under this premise, the conversion of biomass waste to a high-value added product, biochar, is an interesting approach under the circular economy principles. Thus, the improvements in the biochar production and its new and innovative uses are hot points of interest, which are the focus of vast efforts of the scientific community. Biochar has been recognized as a material of great potential, and its use as an adsorbent is becoming a reliable strategy for the removal of pollutants of different streams, according to its high adsorption capacity and potential to eliminate recalcitrant compounds. In this review, a succinct overview of current actions developed to improve the adsorption capability of biochar, mainly of heavy metal and organic pollutants (dyes, pharmaceuticals and personal care products), is summarized and discussed, and the principal adsorption mechanisms are described. The feedstock and the production procedure are revealed as key factors that provide the appropriate physicochemical characteristics for the good performance of biochar as an adsorbent. In addition, the modification of the biochar by the different described approaches proved their feasibility and became a good strategy for the design of selective adsorbents. In the last part of this review, the novel prospects in the regeneration of the biochar are presented in order to achieve a clean technology for alleviating the water pollution challenge.

“…The cost analysis is very important to determine whether the whole production process of the activated char is feasible or not. The cost influencing factors like the availability of raw material, treatment conditions, and other process requirements should be analyzed/estimated [32,33]. Accordingly, considering the raw material (Teff straw) and oven cost is free since the oven heat can be replaced by sunlight, the remaining cost mainly for activation chemicals (i.e.…”

“…It can be seen that the total cost spent to produce biomass-based char varied depending on the preparation process. For instance, Chakraborty et al [32] prepared porous activated biochar using sugarcane bagasse as raw material and 85% H 3 PO 4 as activating agent. Although the production cost is almost equal to the current study, they employed a highly concentrated activation agent which may cause an ill effect on environmental safety.…”

Utilization of low-cost, abundant and biomaterials is highly recommended for sustainable environment protection. This study presents a comparative analysis on the preparation, characterization and cost analysis of the novel activated biochar (BTS) and activated hydrochar (HTS). Teff (Eragrostis tef) straw was used as a precursor for producing BTS and HTS through pyrolysis and hydrothermal carbonization process, respectively. Both chars were further activated using 30 wt% H 3 PO 4 for 3 h activation time. The physicochemical properties of both chars were compared by different characterization techniques including BET, FTIR, XRD, SEM, and TGA. Briefly, BTS exhibited heterogeneous surface structures and comparatively larger specific surface area (627.7 m 2 /g) than that of HTS (43.8 m 2 /g) with the smooth coalesced carbon layer and dull surface edges. The XRD analysis revealed the amorphous character of HTS which is dominantly composed of AlPO 4 , whilst indicating BTS to be the crystalline structure with the very trivial amount of impurities. The oxygen-containing functional groups increased for HTS in comparison to BTS. Thermogravimetric analysis showed that HTS exhibited better thermal behaviors. Estimated costs incurred in the production of the HTS were found to be cheaper than compared to BTS. Overall, the experiment result suggested that Teff straw could have the potential for producing a low cost activated chars.
