Biochar-amended soil can further sorb atmospheric CO2 for more carbon sequestration

Communications Earth & Environment, Journal Year: 2025, Volume and Issue: 6(1)

Published: Jan. 3, 2025

Input of biochar into soil is considered as an efficient technology for carbon sequestration. This work aimed to explore if the extra sorption dioxide (CO2) exists in biochar-amended soil, which has not yet received attention. Here we put and mineral-rich soils perform laboratory CO2 experiments. Our results demonstrate that all increased storage meanwhile further sorb more The Ca or Mg originated could react with eventually be converted inorganic carbonate minerals amended soil. Further, country-level prediction showed cultivated top application China achieve 7.38–12.5 billion tons sequestration additional 0.34–2.66 sorption. require us take consideration both sink assessment potential Application [5%] sequester around 10 China's soils, according experiments pristine four different applications.

Reactive transport simulation of organic and inorganic carbon cycling following carbon dioxide sorption onto soil amendments in drylands

Frontiers in Climate, Journal Year: 2025, Volume and Issue: 7

Published: March 7, 2025

Terrestrial nature-based climate solutions (NbCS) for carbon dioxide removal (CDR) are critical mitigating change. However, the arid climates characteristic of drylands (aridity index <0.65) often limit effectiveness many NbCS. At same time, cover approximately 45% global land area and threatened by soil degradation, necessitating deployment CDR methods that also promote health. Soil amendments with high CO 2 sorption capacity, such as biochar, could provide potential health benefits in provided they do not negatively impact large inorganic pools typical dryland soils. The dynamics therefore assessing response systems to sorbing amendments. To assess sorption, we developed a 1D reactive transport model unsaturated soils equilibrium dissolved calcite under varying respiration rates amendment application conditions. simulations highlight how alteration due biochar affects carbon, pH, Ca 2+ , calcite. transient conditions emerge, including delayed emissions respired emphasize need consider times monitoring campaigns based on measurements. In scenarios where is low, drylands, becomes increasingly important. Although variable was modest relative overall deployment, impacts altered gas important developed.

Modified Biochar Materials From Eucalyptus globulus Wood as Efficient CO₂ Adsorbents and Recyclable Catalysts

Advanced Sustainable Systems, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 9, 2024

Abstract Highly porous carbon materials derived from renewable resources constitute a promising and sustainable strategy regarding the enhancement of CO 2 capture technologies. In this work, valorization Eucalyptus globulus wood, forest invasive species present in European forests, is performed through its transformation biochar. The deposition nitrogen different metals (aluminum, copper chromium) onto biochar performed, using magnetron sputtering as pioneering technique, to produce coated nanoparticles with improved properties. resultant modified particles maintain highly structure remarkable adsorption capacity (up 4.80 mmol g −1 for N@BC ), which attributed synergy their large total surface area (527 m ) microporosity (pore diameter = 21 Å), high content oxygen heteroatom moieties (40.4% N, 11.4% O). Their application heterogeneous bifunctional catalysts cycloaddition epichlorohydrin absence any solvent or co‐catalyst, under moderate conditions (20 bar , 120 °C), leading good conversions 58% conversion) excellent selectivity cyclic carbonates. Cu‐coated shown be more stable than non‐modified material, being recycled reused along 4 consecutive runs without loss catalytic activity selectivity.
