Abstract In the context of climate change and circular economy, biochar has recently found many applications in various sectors as a versatile recycled material. Here, we review application biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, energy storage. The ultimate storage reservoirs are soils, civil infrastructure, landfills. Biochar-based fertilisers, which combine traditional fertilisers with nutrient carrier, promising agronomy. use feed additive animals shows benefits terms growth, gut microbiota, reduced enteric methane production, egg yield, endo-toxicant mitigation. Biochar enhances digestion operations, primarily biogas generation upgrading, performance sustainability, mitigation inhibitory impurities. composts, controls release greenhouse gases microbial activity. Co-composted improves soil properties crop productivity. Pristine engineered can also be employed water remediation to remove pollutants. added cement or asphalt, thus conferring structural functional advantages. Incorporating biocomposites insulation, electromagnetic radiation protection moisture control. Finally, synthesising materials requires additional functionalisation.

Sparking Anaerobic Digestion: Promoting Direct Interspecies Electron Transfer to Enhance Methane Production

iScience, Год журнала: 2020, Номер 23(12), С. 101794 - 101794

Anaerobic digestion was one of the first bioenergy strategies developed, yet interactions microbial community that is responsible for production methane are still poorly understood. For example, it has only recently been recognized bacteria oxidize organic waste components can forge electrical connections with methane-producing microbes through biologically produced, protein-based, conductive circuits. This direct interspecies electron transfer (DIET) faster than exchange via diffusive carriers, such as H2. DIET also more resilient to perturbations increases in load inputs or toxic compounds. However, current digester practices rarely predominates. Improvements anaerobic associated addition electrically materials have attributed increased DIET, but experimental verification lacking. deficiency may soon be overcome improved understanding diversity capable which leading molecular tools determining extent DIET. Here we review microbiology suggest monitoring digesters, and propose approaches re-engineering design encourage

Materials, fuels, upgrading, economy, and life cycle assessment of the pyrolysis of algal and lignocellulosic biomass: a review

Environmental Chemistry Letters, Год журнала: 2023, Номер 21(3), С. 1419 - 1476

Опубликована: Фев. 24, 2023

Abstract Climate change issues are calling for advanced methods to produce materials and fuels in a carbon–neutral circular way. For instance, biomass pyrolysis has been intensely investigated during the last years. Here we review of algal lignocellulosic with focus on products mechanisms, oil upgrading, combining anaerobic digestion, economy, life cycle assessment. Products include oil, gas, biochar. Upgrading techniques comprise hot vapor filtration, solvent addition, emulsification, esterification transesterification, hydrotreatment, steam reforming, use supercritical fluids. We examined economic viability terms profitability, internal rate return, return investment, carbon removal service, product pricing, net present value. also reviewed 20 recent studies found that method highly influenced yield, ranging from 9.07 40.59% 10.1 41.25% biochar, 11.93 28.16% syngas. Feedstock type, pyrolytic temperature, heating rate, reaction retention time were main factors controlling distribution products. Pyrolysis mechanisms bond breaking, cracking, polymerization re-polymerization, fragmentation. Biochar residual forestry could sequester 2.74 tons dioxide equivalent per ton biochar when applied soil thus potential remove 0.2–2.75 gigatons atmospheric annually. The generation bio-oil process is estimated be economically feasible.
