Biochar stability validation – reaching a new level of understanding and transparency
Biochar produced from biomass has large potential to provide negative greenhouse gas emissions as a stable carbon sink in soil. A major hurdle for biochar market establishment is the limited knowledge about the stability of biochar over longer time periods.
In this project, the knowledge is strengthened by performing field trials, incubation trials and novel analysis of available data. The project will involve Swedish and international biochar stakeholders and will develop guidelines for estimation of biochar stability based on biochar origin, properties, and use. Since this topic requires long-term research, field trials are established, planned for long-term analysis, as well as a web app for analysis of future research results. The project can be important for the development of biochar in voluntary markets and policy for carbon dioxide removal, also known as negative emissions.

Large scale deodorization of kraft lignin for thermoplastics – a new testbed
Kraft lignin has a great potential to replace fossil-based materials in many applications due to its availability and molecular structure. However, its characteristic smell can be an issue for indoor applications, working environment reasons and…
