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.

Published: April 20, 2023

Leachate usually includes toxic organic and inorganic pollutants, heavy metals, ammonia nitrogen compounds, other dissolved suspended contaminants. Careful management of landfill leachate (LFL) is essential to reduce quantity prevent the unfortunate fate contamination. In contrast solid waste incinerators, LFL disposal has serious ecological health impacts in most developing countries, mainly associated with groundwater, soil, air pollution. This could be attributed absence cost-effective treatment technology or ideal guidelines by cities/municipalities. Therefore, evaluation sustainable managing collection are highly recommended. review describes classification composition leachates, factors affecting production, conventional (current) options for LFLs. Procedures aerobic anaerobic biological employing microbial operated separately combination along physiochemical processes also discussed. examines prospects methods/techniques, how economize methods (e.g., pretreatment) using readiness level technology, recycling sorting technology.

This review shows that global sugarcane production reached 0.012 billion metric tons of bagasse ash (BA) in 2018, with Brazil, India, and China as top three producers. industrial BA has a high loss on ignition (LOI). Hence, further burning at 800 °C for 1 h or lower temperature 600–650 longer duration up to 3 is the most optimum producing amorphous silica. The average chemical composition used reviewed paper 65% silicon dioxide (SiO2), 9.21% aluminium oxide (Al2O3), 4.64% iron (III) (Fe2O3), 8.31% LOI. exhibits pozzolanic activity can be supplementary cementitious material (SCM). Using 10% dosage replacing ordinary Portland cement (OPC) (by mass) increased long-term (28 days afterward) compressive, flexural, tensile strengths. However, higher dosages 30% produced strength but more than 75% OPC control mortar. requires water superplasticizer (SP) attain similar workability mix due fibrous flakey particles. Most researchers found absorption permeability decrease increases by mass. Concrete containing 20% enhanced durability against sulfate & sulfuric acid attacks, chloride ion ingress, alkali-silica reaction (ASR). recommends sugar industry optimize process produce, conjunction construction industry, standard guideline conformity enhance its use SCM. Also, research should conducted utilizing filler SCM two-stage concrete (TSC), ultra-high-performance (UHPC), self-compacting (SCC).

Sugarcane Bagasse: Challenges and Opportunities for Waste Recycling

Clean Technologies, Journal Year: 2024, Volume and Issue: 6(2), P. 662 - 699

Published: June 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.

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.
