Suello et al. (2025): Increased sea level rise accelerates carbon sequestration in a macro-tidal salt marsh

Rey Harvey Suello, Daan Temmerman, Steven Bouillon, Zeinab Khalifeh, Marinka van Puijenbroek, Kelly Elschot, Ignace Pelckmans, Thorbjørn Joest Andersen, Chris Smit, Jan Bakker, Stijn Temmerman IN: Science of The Total Environment 958, 178075, https://doi.org/10.1016/j.scitotenv.2024.178075

Salt marshes are known as key ecosystems for nature-based climate mitigation through organic carbon sequestration into their sediment beds, but at the same time they are affected by accelerating sea level rise induced by climate warming. Consequently, an important question is how organic carbon accumulation rates (OCAR) of salt marshes will respond to future accelerating rates of relative sea level rise (RSLR). This study studies the OCAR over four decades at two nearby salt marsh sites in the Netherlands, with similar environmental conditions, but with different RSLR rates.

Wang et al. (2024): Microalgae create a highway for carbon sequestration in livestock wastewater: Carbon sequestration capacity, sequestration mechanisms, influencing factors, and prospects

Han Wang, Jiahua Liu, Khinkhin Phyu, Yu’ang Cao, Xiaoyu Xu, Junfeng Liang, Chein-Chi Chang, Keqiang Zhang, Suli Zhi IN: Science of The Total Environment, https://doi.org/10.1016/j.scitotenv.2024.177282

This review discusses the sequestration capacity, technical classification, mechanisms, and factors influencing carbon sequestration by microalgae (MCS) in livestock wastewater. First, the carbon emission characteristics of livestock farm are discussed, concluding that, compared with those from enteric fermentation, emissions from waste management are characterized by dispersed emission points, lack of obvious emission patterns, and difficulties in gas collection. Secondly, the use and potential of MCS in livestock wastewater are summarized, with emphasis on the mechanisms involved (both heterotrophic and autotrophic MCS).

Batjes et al. (2024): Towards a modular, multi-ecosystem monitoring, reporting and verification (MRV) framework for soil organic carbon stock change assessment

Niels H. Batjes, Eric Ceschia, Gerard B.M. Heuvelink, Julien Demenois, Guerric le Maire, Rémi Cardinael, Cristina Arias-Navarro, Fenny van Egmond IN: Carbon Management, 15, https://doi.org/10.1080/17583004.2024.2410812

Consistent and accurate monitoring of changes in soil organic carbon stocks and net greenhouse gas emissions, reporting, and their verification is key to facilitate investment in sustainable land use practices that maintain or increase soil organic carbon stocks, as well as to incorporate soil organic carbon sequestration in national greenhouse gas emission reduction targets. Building up on an initial review of monitoring, reporting and verification (MRV) schemes with a focus on croplands, grasslands, and forestlands the authors develop a framework for a modular, scalable MRV system. They then provide an inventory and classification of selected MRV methodologies and subsequently “score” them against a list of key characteristics.

Carpanez et al. (2024): Potential for nutrients reuse, carbon sequestration, and CO2 emissions reduction in the practice of domestic and industrial wastewater recycling into agricultural soils: A review

Thais Girardi Carpanez, Jonathas Batista Gonçalves Silva, Marcelo Henrique Otenio, Míriam Cristina Santos Amaral, Victor Rezende Moreira IN: Journal of Environmental Management, 370, 122443, https://doi.org/10.1016/j.jenvman.2024.122443

This review assesses the feasibility of reusing treated wastewater for irrigation in agricultural soils as a strategy for nutrients recycling and mitigation of CO2 emissions. Through a literature review, it was examined wastewater sources enriched with carbon and nutrients, including municipal wastewater and associated sludge, vinasse, swine wastewater, as well as wastewater from the food industry and paper and pulp production. The review also explores the dynamics of organic matter within the soil, discussing the aspects related to its potential conversion to CO2 or long-term storage.

Poeplau et al. (2024): Towards an ecosystem capacity to stabilise organic carbon in soils

Christopher Poeplau, Rene Dechow, Neha Begill, Axel Don IN: Global Change Biology, https://doi.org/10.1111/gcb.17453

Soil organic carbon (SOC) accrual, and particularly the formation of fine fraction carbon (OCfine), has a large potential to act as sink for atmospheric CO2. For reliable estimates of this potential and efficient policy advice, the major limiting factors for OCfine accrual need to be understood. The upper boundary of the correlation between fine mineral particles (silt + clay) and OCfine is widely used to estimate the maximum mineralogical capacity of soils to store OCfine, suggesting that mineral surfaces get C saturated. Using a dataset covering the temperate zone and partly other climates on OCfine contents and a SOC turnover model, the authors provide two independent lines of evidence, that this empirical upper boundary does not indicate C saturation.

Shanin et al. (2024): Predicting the effect of climate change and management on net carbon sequestration in the forest ecosystems of the European part of Russia with the complex of models

Vladimir Shanin, Sergey Chumachenko, Pavel Frolov, Irina Priputina, Daria Tebenkova, Anna Kolycheva IN: Ecological Modelling, 496, 110835, https://doi.org/10.1016/j.ecolmodel.2024.110835

The authors have integrated several ecological models (dynamic stand model FORRUS-S, soil organic matter model Romul_Hum, statistical climate generator SCLISS and process-based forest ecosystem model EFIMOD3) to simulate the ecosystem dynamics at the regional level in several study areas within the forest zone of the European part of Russia. The simulation results reflected both the direct effects of climate change and forest management actions on ecosystem carbon pools, and the indirect effects through changes in species composition. The simulation experiments were spatially detailed at the level of individual forest management units, thereby revealing the influence of habitat conditions on the rate of carbon sequestration under the influence of environmental factors.

Bhati et al. (2024): Ultrafast Formation of Carbon Dioxide Hydrate Foam for Carbon Sequestration

Awan Bhati, Mark Hamalian, Palash V. Acharya, Vaibhav Bahadur IN : ACS Sustainable Chemistry & Engineering, https://doi.org/10.1021/acssuschemeng.4c03809

The auhators report ultrafast formation of carbon dioxide (CO2) hydrate foam without the use of any conventional chemical promoters or mechanical agitation. Our 6× enhancement in the CO2 sequestration rate (based on net gas consumption) results from the high flow rate sparging of CO2 gas in water in an open system (constant gas inflow/outflow) in the presence of magnesium. This approach continuously renews the gas–water–hydrate interface, thereby increasing the growth rate. The CO2 gas consumption rate (for hydrate foam formation) and foam composition (hydrate, CO2 dissolved in water, trapped CO2 gas) are experimentally quantified versus various parameters, including thermodynamic (pressure), CO2 flow-related parameters (flow rate, duration), water composition, and quantity of magnesium. The maximum measured CO2 sequestration rate (time-averaged) of 1276.5 g h–1 L–1 MPa–1 is 6 times higher than the fastest reported instantaneous rate.

This paper reviews the latest research progress on the carbon sequestration effects of cement-based binder composite materials under accelerated carbonation methods. It provides a detailed exploration of the influence of cement, admixtures, and additives on the accelerated carbonation outcomes of binding materials. The paper discusses the carbonation capacity of composite binding systems, identifies existing issues, and explores future developments. The aim is to provide practical insights that can enhance the carbon sequestration capability of cement-based binder composite materials. This paper can serve as a technical reference for the construction industry to achieve the goal of “low-carbon emission“ through the utilization of accelerated carbonation technology.

Gilmour et al. (2024): Microbially induced calcium carbonate precipitation through CO2 sequestration via an engineered Bacillus subtilis

Katie A. Gilmour, Prakriti Sharma Ghimire, Jennifer Wright, Jamie Haystead, Martyn Dade-Robertson, Meng Zhang, Paul James IN: Microbial Cell Factories, 23, https://doi.org/10.1186/s12934-024-02437-7

Bacteria play a crucial role in producing calcium carbonate minerals, via enzymes including carbonic anhydrase—an enzyme with the capability to hydrolyse CO2, commonly employed in carbon capture systems. This study describes previously uncharacterised carbonic anhydrase enzyme sequences capable of sequestering CO2 and subsequentially generating CaCO3 biominerals and suggests a route to produce carbon negative cementitious materials for the construction industry.
