“…Eventually, a further study conducted a comparative investigation of various bovine bone parts such as ribs, scapulae, vertebrae, and legs by individually testing their competence under the same operating condition. Bovine rib bonebased biochar then was informed to have the highest sorption capacity followed by scapulae, vertebrae, and legs bone-based sorbents [87].…”

In this review article, the recent development of organic sorbents derived from plant and animal waste for treating polluted aqueous media is presented. The application of biomass has been recognized reliable to adsorb hazardous pollutants contained in wastewater generated by emerging industries. This paper also discusses other existing technologies for removing pollutants including heavy metals, dyes, oil and grease, antibiotic and phenolic compounds from polluted aqueous media. Furthermore, several prominent examples of plant and animal wastes such as eucalyptus bark, pine bark, rice husk, various fruit peels, and animal bones are also properly reviewed. The effects of modification techniques on sorbent performance such as carbonization, pyrolysis, and chemical impregnation using acid or alkaline chemicals are considerably included. Some gaps in current literature are also discussed including the tendency of certain targeted pollutants, the use of simulated aqueous media, the scale of research projects, and the prominent modification procedures. Eventually, based on the relevant literature, clear conclusion has been drawn that these natural disposals have great potentiality as environmentally friendly sorbent alternative to other commercial expensive sorbents, and their reuse has been part of green solutions supporting a circular economy system.

“…In this sense, we could conduct a comparison with the removal capacity of the biochar from Undaria pinnatifida generated by pyrolysis at 500 • C, which registered an adsorption capacity of 125.9 mg g −1 of Cu 2+ [49]; from Ascophyllum nodosum, with a capacity of 223 mg g −1 [50]; and to the steam-activated biochar from Porphyra tenera, with an adsorption capacity of 75.1 mg g −1 of Cu 2+ [9]. These results could also be compared with other removal results obtained [51], where biochar was generated from bovine bone, which presented a high ash content (83.8-87.8%) and was determined to have a Cu removal capacity of 72.53-83.71 mg g −1 . In these cases, the pH was maintained between 4.5 and 5.5, which is contrary to our study where the pH values were variable during the adsorption experiments (i.e., <6.5); thus, the formation of other copper species in solution (such as Cu(OH) + or Cu(OH) 2 ) could co-precipitate on the surface of BCs [18].…”

Seaweed biochar is an efficient alternative bioadsorbent for Cu2+ removal due to its low cost and heavy metal removal capacity. Using the slow pyrolysis process, we produced biochars from Macrocystis pyrifera at 300 (BC300), 450 (BC450), and 600 °C (BC600). The physicochemical and structural properties of the biochar samples improved with increasing pyrolysis temperature from 300 to 450 °C, whereas no significant differences were observed with further increases in temperature to 600 °C. The yield ranged between 49% and 62% and had a high ash content (57.5–71.1%). BC450 and BC600 presented the highest surface areas and higher porosities. The FTIR spectra indicated that an increase of temperature decreased the acidic functional groups due to depolymerization and the dehydration processes, increasing the aromatic structures and the presence of calcium carbonate. The fittings of the kinetic models were different for the BCs: for the BC450 and BC600 samples, the Cu2+ adsorption was well-represented by a pseudo-first-order model; for BC300, a better fit was obtained with the pseudo-second-order model. The rate-limiting step of Cu2+ adsorption on BCs was represented by both models, liquid film diffusion and intraparticle diffusion, with surface diffusion being more important in BC300 and BC600, and intraparticle diffusion in BC450, in agreement with the pore size of the biochar samples. The adsorption isotherms of all BCs showed Langmuir behavior, representative of a chemisorption process, which was corroborated by the energy adsorption values determined by the D–R model. The maximum monolayer Cu2+ adsorption capacities were 93.55 and 58.0 mg g−1 for BC600 and BC450, respectively, whereas BC450 presented the highest affinity. Other mechanisms involved in controlling heavy metal removal from aqueous suspensions using these seaweed biochars remain to be explored. We conclude that BC450 and BC600 from M. pyrifera are the most efficient adsorbents for Cu2+ aqueous removal and are thus an appropriate alternative for bioremediation.

“…Finally, Zone III goes from 576 to 880 °C. The weight loss in this zone is owing to the partial dehydroxylation process of Hap and the decomposition of carbonates . The mass loss in this temperature range is about 6.6% and the maximum rate of mass loss is located at 781 °C.…”

Biogenic Hydroxyapatite Obtained from Bone Wastes Using CO₂-Assisted Pyrolysis and Its Interaction with Glyphosate: A Computational and Experimental Study

In this work, biogenic hydroxyapatite (BHap) obtained from cattle bone waste is proposed as an adsorbent of this dangerous pollutant. Density functional theory (DFT) and calorimetric studies were developed to study the interaction between BHap and glyphosate (GLY). A strong interaction was found in the experiments through the measurement of immersion enthalpy, confirmed by the exothermic chemisorption obtained with DFT calculations. These results suggest that hydroxyapatite is a promising adsorbent material for GLY adsorption in aqueous solutions. In addition, it was determined that the GLY–hydroxyapatite interaction is greater than the water–hydroxyapatite interaction, which favors the GLY adsorption into this material.
