By converting biomass waste like agricultural waste and forestry residues into energy products, biochar provides a new solution for achieving carbon neutrality goals. The quality difference of biochar directly affects its performance and long-term stability in the environment, especially in carbon sequestration and soil improvement. As a key indicator for measuring biochar, the H/C ratio (hydrogen-carbon molar ratio) directly reflects its quality and stability.

What is Torrefaction?Torrefaction is a biomass pretreatment method. It involves heating raw biomass to temperatures between 200 and 300°C in low or no oxyg

As the climate crisis becomes increasingly severe, sustainable energy solutions has become a top priority. As products of biomass pyrolysis and carbonization, biochar and biocoal have gradually become hot spots for research and application. However, are biochar and biocoal the same? How should you choose between them when facing different uses?

As an efficient negative emission technology, biochar has attracted much attention in recent years. However, with the growing voice of sustainable development, people have begun to question whether biochar production is truly sustainable. Compared with traditional fossil energy, from the source of raw materials to biochar production, and then to the final application of biochar, there are signs that biochar is sustainable.

Biochar is a solid carbon-rich material formed by pyrolysis of biomass-based feedstocks at high temperatures in an anaerobic environment. It has received much attention as a soil additive due to its potential benefits, including improved soil structure, increased soil fertility, and carbon sequestration. However, the application of biochar requires careful consideration to maximise its benefits.
