“…Konikkara et al utilized such chromium-contaminated crust leather waste to prepare hierarchical porous carbons for supercapacitor electrodes through precarbonization and KOH activation at four different temperatures (600-900 °C). [77,78] In case of ref. [77], carbons activated at 800 °C delivered the highest specific area (716 m 2 g −1 ) and those activated at 900 °C exhibited the highest specific capacitance (1960 F g −1 ) in 1 m KCl electrolyte.…”

“…On the other hand, ref. [78] begot carbons with high specific surface areas between 613-716 m 2 g −1 and a maximum specific capacitance of 1800 F g −1 with 1 m KOH. Mahto et al utilized otherwise recalcitrant spent wash waste from sugar industry to prepare carbon through a two-step process for utilization as supercapacitor electrodes.…”

“…[ 102 ] Solid waste leather conceived electrodes with an average pore size of 2.6 nm and the highest specific capacitances, viz. 1960 [ 77 ] and 1800 F g −1 , [ 78 ] which are again much above the capacitances of the conventional carbon electrodes. Also, supercapacitor with electrodes fabricated from food waste exhibited the highest energy density of ≈250 W h kg −1 .…”

“…Therefore, of late, due emphasis has also been laid on the evolution of eco-friendly supercapacitors. Benign materials retrieved from carbon-rich agricultural and food biowaste, [9,105,115,116] industrial waste, [76][77][78][79] paper, [74,80,81] and cotton [82] have been used in their fabrication. Additionally, carbon acquired from discarded polymers [83][84][85][86][87][88][89][90][91][92][93][94][95] as well as valuable metals and metal composites recuperated from electronic waste including spent batteries [96][97][98][99][100][101][102] have been utilized in the preparation of supercapacitor electrodes.…”

Supercapacitors store electrical energy on the basis of electrostatic attraction between opposite charges as a result of the formation of an electric double layer (EDL) at the electrolyte/electrode interface. Carbon-derived materials are commonly used to fabricate supercapacitor electrodes owing to their high electrical conductivity, high capacitance, excellent porosity, good electrochemical stability, and large specific surface area. [131-136] Predominantly, these materials include carbon nanotubes (CNTs), graphene, carbon spheres, hollow carbon spheres, carbon nanoparticles (CNPs), etc. [62,137-145] Nevertheless, they fail to demonstrate the desirable performance in practical applications after a certain threshold owing to their short durability and low energy density. Although, metal-organic frameworks (MOFs) have proven to be better electrode candidates in certain aspects, [142,143,146-148] however, these materials incur high cost, low yield of porous carbon, high consumption of metallic nitrate, [62] and hence higher waste generation. Due to the rising concerns of waste production and its management and hence the need for sustainable and cheap resources, reusing and/or converting waste from various sources such as industrial, agricultural, food, and spent electronic devices efficiently into usable carbon has attracted much interest since recently.
