The study found that water washing significantly increases volume shrinkage and accelerates the development of internal porosity. This suggests that simple pretreatments can be used to tune biochar for specific environmental uses, such as soil improvement or water filtration. By providing real-time 3D evidence of the pyrolysis process, this research helps improve the mathematical models used to predict how biomass decomposes. This precision allows for better engineering of carbon materials designed for long-term climate mitigation.
