Sugarcane bagasse (SCB) is the fibrous lignocellulosic residue left over after crushing sugarcane to extract juice for sugar and ethanol production. In this review, a concise overview of existing thermochemical technologies production biochar from SCB its potential applications presented discussed. Some used so far in regard include pyrolysis, gasification, hydrothermal carbonization, torrefaction. However, pyrolysis was found be most widely among them. These processes can affected by several operating conditions such as temperature, heating rate, particle size, residence duration, with temperature being significant efficient variable influencing quality biochar. The yield reported literature ranged 14 % 56 %. A higher obtained at lower than one because decomposes temperatures (>500 °C). has promising agriculture environment, including soil amendment, adsorbent water wastewater treatment, supplementary cementitious material, amongst others. knowledge gaps were also stated study, cost analysis comparison utilizing fuel industries become highly carbon material wide range variety sectors.

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.

Abstract Global energy consumption has drastically increased over the years due to population growth and industrialization. This prompted an exploration for clean renewable alternatives. Microalgae are widely recognized as a promising third‐generation source because they have capability generate biofuels, including biochar. The utilization of microalgal biomass been gaining traction their advantages, such fast growth, high rate production, carbon‐fixing efficiency. Thermochemical methods like hydrothermal carbonization, torrefaction, pyrolysis can be employed harness from microalgae. different thermochemical converting into biochar discussed, well factors affecting these methods. In addition, dedicated section covered components properties generated biochar, its thermal surface properties. Furthermore, economic analysis production microalgae applications microalgae‐derived were presented along with suggestions further research.

Used COVID-19 masks produce a large amount of garbage that frequently overwhelms waste management facilities, hence they are disposed improperly. It is imperative to develop processing technique harnesses disposable face create biofuel in order address the environmental problems caused by their disposal. In this study, biochar production through co-carbonization mask and biomass (Daniella oliveri leaves) using fixed-bed updraft reactor was investigated as means recycling wastes for sustainable environment. A hybrid with 40.20 wt% yield produced at peak temperature 350 °C, while 32.87 only high 279 °C. According sample analysis, biochar, which has specific surface area 397.8 m2/g, very porous numerous cracks fissures. The Fourier transform infrared analysis showed presence functional groups, mainly hydroxyl carbonyl co-carbonized mask, indicating possibility an adsorbent increase soil fertility.

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.
