Thermochemical co-conversion of biomass-plastic waste to biochar: a review

Green Chemical Engineering, Journal Year: 2023, Volume and Issue: 5(1), P. 31 - 49

Published: March 15, 2023

Biomass and plastics are two of the most common municipal solid wastes globally that have continuously placed a burden on environment. It is therefore important they properly recycled. Thermochemical co-conversion offers valuable opportunity to recycle biomass simultaneously into biochar, which reduces time cost recycling them individually while producing material with wide range applications. This study review published literature discusses thermochemical co-processing plastic biochar. was observed co-pyrolysis co-hydrothermal carbonization commonly utilized technologies for this process. The characteristics different been thermochemically converted biochar were compared. properties resulting affected by feedstock composition, pre-treatment blending ratio, reactor's configuration, reaction temperature, presence catalyst. Most studies found treating feedstocks separately resulted in lower yield than processing together. created procedure has used as soil additive an adsorbent water treatment. Future perspectives suggestions, such necessity some technical advancement, biochar's economic benefits, improved government participation, raised social awareness, also made. These factors potential propel field great horizons.

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.

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.

Published: Feb. 8, 2024

Food waste, particularly animal-derived presents a significant challenge globally, prompting the need for sustainable management strategies. In 2022, amount of food waste per capita reached 131 kg/capita in EU (European Union), which is why search environmentally friendly ways to manage through thermochemical conversion processes has gained momentum recent years. Animal-derived good source organic matter (proteins, lipids, and polysaccharides) mineral compounds (calcium phosphate, mostly hydroxyapatite). This composition makes valuable extraction chemical compounds, such as hydroxyapatite (HAp), constitutes up 70 wt% animal bones; keratin; collagen; hyaluronic acid (HA), produce pharmaceutical, medical, or industrial by-products. The chicken bones pyrolysis gasification creates new opportunity valorize this type by reintroducing by-products into economy thus achieving objectives. results study showcase multiple applications bone products (as adsorbents aqueous mediums, catalysts, fertilizers, biomedical applications) necessity better exploration process waste. Therefore, explores properties discusses influence conditions on product yields, catalytic enhancement these processes.
