Valorization of waste cassava peel into biochar: An alternative to electrically-powered process

Total Environment Research Themes, Journal Year: 2023, Volume and Issue: 6, P. 100029 - 100029

Published: Feb. 11, 2023

Cassava production and consumption in its raw or processed form have experienced a rise recent times globally, with Nigeria being the major producer of cassava world. However, increased this crop has resulted an increase peels, which if not properly disposed recycled, would burden environment. Previous studies only been able to engage electrically-powered reactors for thermochemical conversion these is challenge as cannot be used regions insufficient supply electricity. In study, authors utilized top-lit updraft reactor retort heating waste peels into biochar. The reactor, relatively cheap, simple use, environmentally friendly modified biochar production, biomass-powered. carbonization process, lasted 160 minutes, obtained peak temperature 338 ℃, gave yield 55.13%. FTIR analysis revealed that peel consists similar functional groups relation precursor, but more oxygenated groups. BET surface area BJH pore diameter were 319.784 m2/g 2.447 nm, respectively. EDX showed majorly made up carbon (56.93%) silver (22.97%). SEM micrographs rough porous surface. DTA/TGA results process improved thermal efficiency material.

Advancing the circular economy through the thermochemical conversion of waste to biochar: a review on sawdust waste-derived fuel

Biofuels, Journal Year: 2023, Volume and Issue: 15(4), P. 433 - 447

Published: Sept. 13, 2023

AbstractBiochar is a solid material that contains lot of carbon and created by heating biomass in an environment where there little or no oxygen. It has become clear biochar holds great promise for combating climate change, enhancing soil fertility, eliminating pollutants, promoting effective waste disposal. In particular, sawdust produced via thermochemical processes drawn attention because its affordability abundant availability. This review paper presents general summary the production processes, including pyrolysis, hydrothermal carbonization, torrefaction, gasification. was observed specific yields performance these methods vary depending on feedstock source, process parameters, equipment used. Additionally, properties biochar, such as content, surface area, stability, also method. The effects operating factors sawdust-biochar temperature, rate, residence duration, are covered study. While challenges exist, ongoing research aims to improve applications, making it valuable tool climate-smart agriculture sustainable land management.Keywords: Biocharsawdustthermochemical processespyrolysiswaste management Disclosure statementNo potential conflict interest reported author(s).Additional informationFundingThis work received external funding.

Recovery of metallic oxide rich biochar from waste chicken feather

Low-carbon Materials and Green Construction, Journal Year: 2023, Volume and Issue: 1(1)

Published: Feb. 13, 2023

Abstract Over the years, devastating impact of climate change has become pronounced due to inadequate regulation for waste disposal in a developing country like Nigeria. The chicken feather-based metal oxide-rich (MOR) biochar was produced using top-lit updraft reactor at peak temperature 417.2 °C give yield 28.19%. results were analyzed Brunauer-Emmett-Teller BET, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Energy Dispersive (EDS), and fluorescence spectroscopy (XRF). result shows that sample is mesoporous (pore diameter 2.132 nm) with BET surface area 105.7 m 2 /g. CaO (33.147 wt%) SO 3 (25.673 major oxides present notable proportions on material surface, which evident SEM micrograph. elemental compositions raw oxygen (36.917 calcium (23.690 wt%), minerals quartz, marialite, davyne, graphite. study elucidates successful efficient recovery route preparation adsorbents precursors many product synthesis processes.

Enhancing biochar properties through doping: A comparative study of sugarcane bagasse and chicken feather

Biofuels, Journal Year: 2023, Volume and Issue: 15(6), P. 627 - 634

Published: Oct. 30, 2023

This comparative study explores the production and characterization of biochar derived from a combination sugarcane bagasse (SB) chicken feathers (CF), with doping strategy for each biomass in other. Two biochars, SB92CF-BC (92% SB 8% CF) CF92SB-BC CF SB), were produced using top-lit updraft reactor, resulting yield 34% 27%, respectively. Fourier transform infrared spectroscopy (FTIR) analysis revealed characteristic functional groups both minimal impact process. Scanning electron (SEM) showed distinct morphological features, exhibiting smoother surface displaying an irregular rough morphology. Energy dispersive X-ray (EDS) confirmed presence several elements higher nitrogen content CF92SB-BC. Brunauer-Emmett-Teller (BET) demonstrated significant specific areas exceeding those reported unmodified biochars. The findings suggest potential synergistic effects strategy. expands knowledge on diverse sources highlights utilizing lignocellulosic non-lignocellulosic waste materials sustainable production.
