“…Similarly, the Pseudo-Second-Order Kinetics model finds application in scenarios such as the adsorption of antidepressants like fluoxetine onto activated hydrochar. It aids in assessing the rate constant and predicting the equilibrium adsorption capacity [83]. In cases involving the adsorption of antipyretics, like acetaminophen, the Intraparticle Diffusion Model is pertinent.…”

Water contamination is a pervasive global crisis, affecting over 2 billion people worldwide, with pharmaceutical contaminants emerging as a significant concern due to their persistence and mobility in aquatic ecosystems. This review explores the potential of activated hydrochars, sustainable materials produced through biomass pyrolysis, to revolutionize the removal of pharmaceutical contaminants from water sources. These materials possess high surface area, porous structure, and exceptional adsorption capabilities, making them a promising solution. The impact of pharmaceutical contaminants on aquatic ecosystems and human health is far-reaching, affecting biodiversity, water quality, and public health. To address this complex issue, a diverse range of techniques, including adsorption, biodegradation, and advanced oxidation processes, are employed in the pharmaceutical industry. Activated hydrochars offer substantial adsorption capacity, sustainable feedstock origins, and a minimal carbon footprint. This review highlights their potential in pharmaceutical contaminant removal and their broader applications in improving soil and air quality, resource recovery, and sustainable waste management. Interdisciplinary collaboration and the development of intelligent treatment systems are essential to fully unlock the potential of activated hydrochars. Regulatory support and policy frameworks will facilitate their responsible and widespread application, promising a cleaner and more sustainable future. This paper aims to inform scientists, environmental experts, policymakers, and industry stakeholders about the promising role of activated hydrochars in addressing pharmaceutical contaminant challenges.

“…This characteristic enables electron transfer reactions, facilitates strong complexation with pollutants, and also provides basic character to the carbon matrix [69,141]. This grafting process can be carried out either in a one-step, one-pot strategy [61], or in a two-step procedure involving the mixing of the carbonaceous matrix with the chosen compound [142].…”

“…The synthesis involved a post-pyrolysis step, which included alkali activation and PEI grafting using the crosslinker GTA, reporting a maximum adsorption capacity of PEI-alkali-biochar for Cr of about 435.7 mg/g. Similarly, Escudero-Curiel et al [61] prepared two N-doped hydrochars derived from olive pomace, or "alperujo", with urea and PEI in one-step, one-pot modification to remove a drug mixture of fluoxetine and cefazolin from aqueous media. In both instances, the formation of amide groups played a beneficial role in facilitating the adsorption process.…”

Agri-food residues or by-products have increased their contribution to the global tally of unsustainably generated waste. These residues, characterized by their inherent physicochemical properties and rich in lignocellulosic composition, are progressively being recognized as valuable products that align with the principles of zero waste and circular economy advocated for by different government entities. Consequently, they are utilized as raw materials in other industrial sectors, such as the notable case of environmental remediation. This review highlights the substantial potential of thermochemical valorized agri-food residues, transformed into biochar and hydrochar, as versatile adsorbents in wastewater treatment and as promising alternatives in various environmental and energy-related applications. These materials, with their enhanced properties achieved through tailored engineering techniques, offer competent solutions with cost-effective and satisfactory results in applications in various environmental contexts such as removing pollutants from wastewater or green energy generation. This sustainable approach not only addresses environmental concerns but also paves the way for a more eco-friendly and resource-efficient future, making it an exciting prospect for diverse applications.
