BIOCHAR ACTIVATED CARBON Biochar is the most recent addition to the activated carbon family. Biochar carbons are those produced by a pyrolysis process with extremely low carbon emissions, a carbonization process that takes raw products straight through to the activation stage in less than an hour depending on the temperature range. The pyrolysis process can be designed to maximize for energy to run electrical turbines, or to produce biofuels. Both these processes result in a low activity biochar with a high ash content. Or the process can be designed to produce highly active biochars with a low ash content, without wasting valuable carbon to the atmosphere. Biochars are seen as more environmentally responsible compared to charcoals produced by conventional burning practices which emit large amounts of carbon. Carbon retention is on the order of 96% from pyrolysis, compared to 50% from conventional methods.
