We are currently working on creating biochars from various biomass waste sources, including food waste. We are primarily looking into these for energy but also for other applications. We have found that the impact of the inorganic content strongly impacts the reactivity of the biochars for subsequent gasification reactions. Here is a video of Derek and Delphine showing their leaching process to study the impact of removing inorganics on biochar reactivity.
Here is an explanation of how it can be used for an alternative BECCS (Bioenergy with Carbon Capture and Storage) process with an alternative combustion processes (solid oxide fuel cells) that enable easier (in-situ) separation of carbon dioxide.
