This article aims to add to the emerging empirical mitigation deterrence literature by drawing on ongoing research into a particular form of greenhouse gas removal technology – biochar – and associated biochar carbon markets. As such, the aim of this paper is to explore whether the UK carbon market for biochar, in practice is likely to contribute to delays in emissions reduction. In other words, the authors explore whether UK biochar carbon markets are (likely to be) as much of a problem for mitigation deterrence as imagined or envisaged within the mitigation deterrence literature. They draw from original data collected in 2022 from 33 semi-structured interviews with mostly UK based experts who have an interest or potential interest in biochar, supplemented with a document analysis.

After its application to soil, biochar suffers an ageing process, able to deteriorate its functional properties as soil improver. However, at present, it is not clear how to evaluate biochar ageing. The main aim of this study is to evaluate biochar ageing by determination of temporal changes on (a) soil respiration after biochar addition and (b) the relationship between CO₂ adsorption capacity and wettability of biochar as measurable parameters indicating biochar ageing.

In this work, the affinity of biochar, produced from softwood via fast pyrolysis at 500 °C, for CO and CO₂ was first predicted using molecular modeling binding energy calculations. The results suggested that CO₂ would be favored over CO for adsorption on biochar because of its stronger adsorption (higher released adsorption energy). The biochar adsorption of pure CO and CO₂ were then studied using batch and dynamic experiments, where the isotherm and kinetic models of the pure gas adsorptions were derived. Dual-site Langmuir isotherm fitted both of the gases equilibrium adsorption data the best, confirming the non-homogeneous surface of biochar.

Biochar has been proposed as an established technology for carbon sequestration with co-benefits in terms of soil quality and crop yield. However, the considerable uncertainties that exist in the potential, cost, and deployment strategies of biochar systems at national level prevent its deployment in China. Here, the authors conduct a spatially explicit analysis to investigate the negative emission potential, economics, and priority deployment sites of biochar derived from multiple feedstocks in China.

Biochar used for soil amendment is considered a viable negative emissions technology as it can be produced easily from a wide range of biomass feedstocks, while offering numerous potential agricultural benefits. This research is the first to present a comprehensive sustainability assessment of large-scale biochar production and application in Malaysia.

The utilisation of biochar in concrete has attracted considerable attention due to its potential in enhancing the properties and sustainability of this construction material. This in-depth review delves into various aspects of biochar-concrete composites.

Biochar has been widely recognized for its potential to increase carbon sequestration and mitigate climate change. This potential is affected by how biochar interacts with native soil organic carbon and fresh organic substrates added to soil. However, only a few studies have been conducted to understand this interaction. To fill this knowledge gap, the authors conducted a ¹³C-glucose labelling soil incubation for 6 months using fine-textured agricultural soil (Stagnosol) with two different biochar amounts.

Biochar (BC) use in water treatment is a promising approach that can simultaneously help address societal needs of clean water, food security, and climate change mitigation. However, novel BC water treatment technology approaches require operational testing in field pilot-scale scenarios to advance their technology readiness assessment. Therefore, the objective of this study is to evaluate the system performance of BC integrated into hydrous ferric oxide reactive filtration (Fe-BC-RF) with and without catalytic ozonation (CatOx) process in laboratory and field pilot-scale scenarios. For this investigation, Fe-BC-RF and Fe-CatOx-BC-RF pilot-scale trials were conducted on synthetic lake water variants and at three municipal water resource recovery facilities (WRRFs) at process flows of 0.05 and 0.6 L/s, respectively.
