The University of Aberdeen is offering a fully funded PhD project to address a critical challenge in the biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More industry: verifying its long-term carbon storage permanence. This research aims to establish a new standard for evaluating biochar stability, which is essential for its role in climate change mitigation, sustainable agriculture, and soil conservation.

While biochar is recognized for its potential in carbon sequestration and soil improvement, its value depends on its resistance to environmental degradation. Current methods for measuring this stability are often expensive, slow, and lack sufficient detail, hindering the validation of carbon credits and the optimization of production processes. This project will pioneer the use of Raman spectroscopy, a laser-based technique, to provide a more efficient and detailed analysis of biochar’s nanoscopic chemical structure, which is directly linked to its longevity in the soil.

The research will involve developing innovative protocols, comparing Raman spectroscopy with other advanced laboratory techniques, and conducting international fieldwork to study natural chars in various ecosystems. A key outcome will be the creation of the first open-source database of chemical data for biochar from global manufacturers. This database is intended to provide crucial guidance for producers, carbon credit auditors, and investors, ultimately setting a new industry standard for assessing biochar permanence and effectiveness.
