Biochar, as a carbon-rich substance produced from the thermal decomposition of organic biomass, is promising for sustainable environmental management. The production and consumption this can directly indirectly lead to reduction carbon emissions and, result, in neutralizing effects global warming climate change actively participate. biochar route be even more powerful than bioenergy terms targets. In line with these facts, review tries study biochar, its by slow diverse applications reduce ecosystem stability. Also, such sequestration, soil strengthening, reducing pollutants are technically environmentally discussed. Biochar's adaptability consistent development goals, making it valuable tool tackling challenges change, degradation, pollution control. Through process pyrolyzing residues producing possible avoid cumulative 66–130 billion metric tons CO2 equivalent over century. Approximately 50 % avoided result long-term sequestration capabilities biochar. Additionally, 30 reductions come substituting fossil fuels pyrolysis-derived energy, while remaining 20 arise prevention methane nitrous oxide emissions. Reflecting growing significance, industry, valued at approximately USD 541.8 million 2023, poised remarkable growth. Projected expand an impressive annual rate 13.9 2024 2030.

Sugarcane bagasse-based biochar and its potential applications: a review

Emergent Materials, Год журнала: 2023, Номер 7(1), С. 133 - 161

Опубликована: Дек. 8, 2023

Abstract The effective management of agro-industrial waste plays a pivotal role in mitigating various forms pollution. Sugarcane bagasse (SB), substantial biomass generated the sugar industry after cane juice extraction, necessitates sustainable handling. Although some mills utilize wet sugarcane for fueling milling process, significant portion remains stockpiled and is often incinerated on-site, resulting highly flammable that poses risks to its surroundings. Recognizing importance addressing this issue, researchers have identified conversion agricultural into biochar as an efficient means harnessing energy following devolatilization. There scientific interest transformation value-added products, including biochar, biogas, biofuel. This comprehensive literature review delves pyrolysis processes applicable converting char materials, showcasing potential diverse applications line with current interests. Graphical

Biochar affects compressive strength of Portland cement composites: a meta-analysis

Biochar, Год журнала: 2024, Номер 6(1)

Опубликована: Март 6, 2024

Abstract One strategy to reduce CO 2 emissions from cement production is the amount of Portland produced by replacing it with supplementary cementitious materials (SCMs). Biochar a potential SCM that an eco-friendly and stable porous pyrolytic material. However, effects biochar addition on performances composites are not fully understood. This meta-analysis investigated impact 7- 28-day compressive strength based 606 paired observations. feedstock type, pyrolysis conditions, pre-treatments modifications, dosage, curing type all influenced composites. Biochars obtained plant-based feedstocks (except rice hardwood) improved 3–13%. at temperatures higher than 450 °C, heating rate around 10 C min -1 , increased more effectively. Furthermore, small particle sizes 2–7% compared those without addition. dosage < 2.5% binder weight enhanced both strengths, common methods maintained effect when mixing cement, adding fine coarse aggregates such as sand gravel affects concrete mortar's strength, diminishing making nonsignificant. We concluded appropriate could maintain or enhance mechanical performance composites, future research should explore mechanisms Graphical

Valorization of engineered biochar to develop ultra-high-performance fiber-reinforced concrete with low carbon emission

Journal of Sustainable Cement-Based Materials, Год журнала: 2024, Номер 13(6), С. 865 - 887

Опубликована: Апрель 1, 2024

This research introduces an innovative approach to developing carbon-negative Ultra-High-Performance fiber-reinforced Concrete (UHPC) by incorporating substantial quantities of biochar, both as a binder and aggregate, replacing up 25% weight Ordinary Portland Cement (OPC) quartz sand (QS). The study examines the impact biochar on cement hydration processes, microstructure evolution, various other performance metrics in modified UHPC. Samples were formulated with 3% double-hooked steel fibers ranging from 5 substitutes for OPC QS. investigation included assessments changes rheological properties, strength metrics, long-term shrinkage, resistance sulfate attacks, freeze-thaw durability, analysis, cost-benefit evaluation. Test results indicated that biochar-incorporated samples exhibited 20% increase heat evolution end seventh day plastic energy at 28 days rose 32.14% compared control biochar-augmented versions. Shrinkage reduction varied between 58 69% 210 biochar. Specifically, mix containing (G2-M5-BC-20) significantly improved 90-day compressive flexural 8.9 9.3%, 30.6 36.8%, respectively, while further inclusion showed no marked enhancement metrics. G2-M5-BC-20 also demonstrated excellent attacks cycles, exhibiting least mass loss highest residual strength. An initial revealed biochar-enhanced UHPC could offer compelling financial benefits. Given its mechanical behavior, potential harmful CO2 emissions, economic viability, emerged most promising formulation, potentially generating overall profit $36 per cubic meter.
