“…Furthermore, graphitic layers in tea waste biochar may form π – π interactions through the aromatic structure, surface carboxylic acid, nitro and ketones on the biochar with amino functional groups, and O and/or N‐hetero‐aromatic rings in selected pharmaceuticals such as tetracycline and sulfamethazine (Li, Zhang, Xu, Mei, et al, 2021; Upamali et al, 2014). Pore filling has been reported as a plausible adsorption mechanism for highly porous adsorbents (Wong et al, 2021). In the analysis of adsorption mechanism for the uptake of norfloxacin by coffee husk, the norfloxacin‐loaded and free adsorbents were analyzed by FTIR (Figure 3a) to identify the functional groups responsible to adsorb norfloxacin (Paredes‐laverde et al, 2018).…”

The introduction of large amounts of pharmaceuticals into the environmental waters is well‐documented in literature with their occurrence reported in all different water matrices accessible to humans and animals. At the same time, the increasing consumption of coffee and tea‐based beverages results in the generation of solid waste, which is mostly disposed‐off in the environment. To minimize environmental pollution, coffee and tea‐based materials have been proposed as suitable options to remove pharmaceuticals in environmental waters. Therefore, this article provides a critical review on the preparation and applications of coffee and tea‐based materials in removing pharmaceuticals from contaminated water. In this context, most studies in literature focused on the applications of these materials as adsorbents, while only limited work on their role in degradation of pharmaceuticals is discussed. The successful application in adsorption studies is attributed to high surface areas of adsorbents and the ability to easily modify the adsorbent surfaces by incorporating functional groups that provide additional oxygen atoms, which promote easy interactions with pharmaceuticals. Hence, the adsorption mechanisms are mostly described by hydrogen bonding, electrostatic and π–π interactions with sample pH playing a dominant role in the adsorption process. Overall, the present article focused on the developments, trends and future research direction on the preparations and applications of coffee and tea‐based materials for efficient removal of pharmaceuticals in water. Practitioner Points Review of tea and coffee wastes application for removal of pharmaceuticals in water Key applications in adsorption and degradation of pharmaceuticals in water Removal mostly explained by hydrogen bonding, electrostatic, and π–π interactions Trends, gaps, and future research to be explored are reviewed and highlighted

“…In such circumstances, it is essential to look for sufficient, sustainable carbon supplementary for the production of carbon-based materials. 5 The production of carbon materials that have been used are a variety of bio-wastes, including rotten carrots, 6 bamboo, 7 cotton stalks, 8 palm wood, 9 coconut shell, 10 tea leaves, 11 corn crop, 12 rice husk, 13 olive stones, 14 and mango dead leaves. 15 One of the main and most affordable natural bio-wastes is peanut shell.…”

Modern energy and ecological sustainability can be accomplished, in part, by using activated bio char-based electrodes made from biomass waste in energy-producing devices like metal-air batteries and fuel cells. Herein, a simple method of combining pyrolysis graphitization with DC glow discharge plasma is used to create highly disordered carbonaceous materials incorporating surface functional groups from a readily available and inexpensive bio waste of peanut shells. The synthesized activated peanut shell carbon material displays remarkable supercapacitance performance in 2M KOH at elevated specific capacitances (537 Fg-1 at 10mVs-1) and catalytic ability for the oxygen reduction response at a half-wave peak of 0.19 V. Water contact angle and dispersion studies showed a considerable improvement in the surface's hydrophilic following plasma treatment, and Fourier transform infrared and Raman spectroscopy were also used to evaluate the surface's functional group and micro structure. In this study, a simple, affordable, and environmentally-friendly method for making activated disordered carbon is revealed. It is then investigated as a potential electrode for supercapacitor, metal air battery, and fuel cell applications.
