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

Green Chemical Engineering, Год журнала: 2023, Номер 5(1), С. 31 - 49

Опубликована: Март 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.

Sugarcane Bagasse: Challenges and Opportunities for Waste Recycling

Clean Technologies, Год журнала: 2024, Номер 6(2), С. 662 - 699

Опубликована: Июнь 3, 2024

Sugarcane has primarily been used for sugar and ethanol production. It creates large quantities of residual lignocellulosic biomass such as sugarcane bagasse, leaves, tops, vinasse. Biomass is a sustainable prospect biorefineries aiming to optimize production processes. We detail recent research developments in recycling sugarcane, including energy generation pyrolysis obtain biofuels, example. To produce biochar, the cost operating at high temperatures large-scale remain obstacles. The prospects can be enhanced by pellet production; however, it requires an improvement quality control long-term storage or long-distance transportation. In civil construction, materials still need prove their efficiency reliability. Related adsorbent materials, use bagasse advantage being low-cost environmentally friendly. Nevertheless, extraction, functionalization, modification cellulose fibers, improve adsorption properties even mode operation, challenges. synthesis nanostructures lacking yields ability scale up. Finally, controlling dispersion orientation avoiding fiber agglomeration could mechanical response composites using bagasse. different possibilities its residues reinforce importance this material industry global economy. Thus, present work addresses current challenges perspectives industrial processes involving support future on waste-derived subjects.

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.
