“…The cost of AC production significantly depends on the precursor of AC. In this regard, the production of AC has been investigated with inexpensive material such as waste potato residue, almond shell, waste rice hulls and seaweed [12][13][14][15]. Walnut shell is considered as a good candidate for conversion to AC due to its relatively high carbon content.…”

“…After this, bio‐carbon can be produced, and after condensation of vapours, it is possible to obtain bio‐oil (Liang et al , ). Also, activation, washing and drying can be performed to obtain activated carbon (Zhang et al , ). We will focus, nevertheless, in the liquid fraction that can be decanted to obtain starch (Fig.…”

Summary Potato tubers of Group Phureja have a great relevance in terms of production and consumer acceptance in the Andean countries. However, its proximal characteristics, nutritional value and bioactive compounds have been scarcely known. For the first time, this work aims to give an overview on tubers of Group Phureja characteristics, including research works from 1993 to 2019. When analysing the micronutrients and bioactive analytes, sodium, niacin and carotenoid contents are higher as compared to those of the Group Tuberosum. Likewise, the application of a biorefinery approach for the valorisation of Group Phureja wastes was proposed. These wastes may come from tubers that fail to meet quality parameters or by processing potato products. The possibility of obtaining useful compounds for the food, feed, materials, energy and chemical industries is described. The strategy of valorisation of wastes was focused on the production of starch and proteins, previously reported with important technological properties.

“…To reduce the high costs, agricultural wastes and residues are used as a precursor for activated carbon (Ahmad et al 2014). In fact, cherry kernels (Iakovleva et al 2017), rice bran (Hong and Wang 2017), coir pith ash (Bahar et al 2018), wheat straw (Lin et al 2017), potato residue (Zhang et al 2015), rice straw (Sangon et al 2018), coconut coir dust (Etim et al 2016), orange peels (Rožič et al 2014), and wood apple shell (Sartape et al 2017) among others have been used for dye removal in aqueous solutions in the recent literature. However, most of these contain low adsorption capacity.…”

Utilization of a novel activated carbon adsorbent from press mud of sugarcane industry for the optimized removal of methyl orange dye in aqueous solution

In this study, a novel activated carbon adsorbent from the press mud of a sugarcane industry was used to remove methyl orange dye (MOD) from aqueous solution and was optimized via response surface methodology using the central composite design. The adsorbent was characterized by FTIR and SEM analysis and showed the presence of functional groups such as alcohols, nitriles, amides, alkane, alkyl halides, and alkenes, and it also showed fibrous surface morphological appearance. The factors affecting MOD adsorption, such as initial concentration, adsorbent dose, and contact time were examined, and optimal pH 2.0 to remove MOD in an aqueous solution that is found in various studies is also utilized. The results showed maximum MOD removal rate of 98.68% when the initial concentration, adsorbent dose, and contact time were optimally set as 24.17 mg/L, 0.5 g, and 20 min, respectively. The analysis of the equilibrium data revealed that MOD adsorption using press mud activated carbon best fitted the Langmuir isotherm (R 2 = 0.96103) which implies monolayer adsorption process. Also, the kinetics of MOD adsorption using press mud activated carbon followed a pseudo-first-order model (R 2 = 0.96096) which means that the active sites are proportional to the non-active sites during the adsorption process.
