“…Solution pH is also an important parameter to consider for the effective adsorption process, which affects the properties of both adsorbents and pollutants (Liu et al, 2012;Marzbali et al, 2016;Ahsan et al, 2018;Alidadi et al, 2018;Jang et al, 2018;Selmi et al, 2018;Jang and Kan, 2019;Nguyen et al, 2019;Premarathna et al, 2019). The pH PZC of BC800 was 8.27 (see Figure 3A), which is relatively high.…”

“…Aquatic ecosystem pollution by antibiotics has received rising concerns due to their potential hazards on the aquatic biota and even human beings (Liu et al, 2012;Jang et al, 2018;Premarathna et al, 2019). The tetracycline (TC) group is one of the most widely applied antibiotics in human therapy and the livestock farming globally thanks to their comparatively low prices and efficient treatment (Liu et al, 2012;Nguyen et al, 2019). TC is hard to metabolize and was extensively excreted (up to 90%) in urine and feces from human and animals (Jang et al, 2018;Li et al, 2018;Selmi et al, 2018;Jang and Kan, 2019).…”

In this study, biochars derived from waste fiberboard biomass were applied in tetracycline (TC) removal in aqueous solution. Biochar samples were prepared by slow pyrolysis at 300, 500, and 800 • C, and were characterized by ultimate analysis, Fourier transform infrared (FTIR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET), etc. The effects of ionic strength (0-1.0 mol/L of NaCl), initial TC concentration (2.5-60 ppm), biochar dosage (1.5-2.5 g/L), and initial pH (2-10) were systemically determined. The results present that biochar prepared at 800 • C (BC800) generally possesses the highest aromatization degree and surface area with abundant pyridinic N (N-6) and accordingly shows a better removal efficiency (68.6%) than the other two biochar samples. Adsorption isotherm data were better fitted by the Freundlich model (R 2 is 0.94) than the Langmuir model (R 2 is 0.85). Thermodynamic study showed that the adsorption process is endothermic and mainly physical in nature with the values of H 0 being 48.0 kJ/mol, S 0 being 157.1 J/mol/K, and G 0 varying from 1.02 to −2.14 kJ/mol. The graphite-like structure in biochar enables the π-π interactions with a ring structure in the TC molecule, which, together with the N-6 acting as electron donor, is the main driving force of the adsorption process.

Some researchers [6,27,35,37,62,63,64,65] have used SCG in different forms (e.g. raw SCG, SCG combined with chitosan and poly(vinyl alcohol), biochar from SCG, NaOH-activated biochar from SCG, hydrochar from SCG, AC from SCG, AC from SCG with chemical activated) as adsorbent for pharmaceuticals removal (such as metamizole, acetylsalicylic acid, acetaminophen, caffeine, sulfadiazine, sulfamethoxazole, paracetamol).…”

Nowadays, the water contamination which is due to pharmaceuticals is increasing and alarming. The pharmaceuticals in water are very hazardous and toxic not only for the human life but also for environment. One of the promising methods of removing pharmaceuticals from the contaminated water is adsorption. Agricultural and industrial wastes or by-products can be used as low-cost adsorbents for pharmaceuticals removal. Low-cost adsorbents provide particular economic and environmental advantages. This paper presents an overview of utilizing of the waste-based adsorbents (mainly spent coffee grounds) for the removal of pharmaceuticals from water.

“…With a view to CE, coffee residues can also be applied in the environmental engineering sector. Their main use is related to their application as adsorbent materials in order to remove dyes (Wen et al, 2019), contaminants of emerging concern (CECs) such as pesticides and pharmaceutical products (Dai et al, 2019, V-T Nguyen et al, 2019, and heavy metals (Futalan et al, 2019). Regarding the removal of dye from WW and aqueous waste, Shen and Gondal (2017) tested exhausted coffee ground powders adsorbent for the removal of Rhodamine B and Rhodamine 6G by batch adsorption experiments.…”

Valorization of agro-industry residues in the building and environmental sector: A review

et al. 2020

View full text Add to dashboard Cite

Environmental pollution has become a relevant issue as the population rises and resources decrease. Reuse and recycling still have the greatest potential as they turn the waste into a new resource, representing the ‘closed-loop’ step of a circular economy (CE). Looking for new applications for agro-industry waste represents both an environmental issue, as its incorrect disposal is a cause of pollution, and a chance to exploit zero-cost natural wastes. The present review, with around 200 articles examined, focuses on possible reuses of these residues in (a) building construction, as additives to produce thermal and acoustic insulation panels, and (b) in water treatments, exploited for removal of pollutants. The selected materials (coconut, coffee, corn, cotton and rice) have industry production wastes with suitable applications in both sectors and huge worldwide availability; their reuse may thus represent a new resource, with an impact based on the production rate and the possible replacement of current inorganic materials. Along with possible implementation of the selected materials in the building industry and environmental engineering, a brief description of the production and supply chain are provided.
