31-Mar-2011 - Portugal

Researchers investigating the potential of renewable spent coffee grounds as a feedstock for biodiesel production discovered that they could couple the extraction and Transesterification of spent coffee grounds oil into a single step. They used supercritical methanol, either pure or with carbon dioxide, to reduce the operating temperature and pressure. Integrating the extraction and transesterification stages in one single step could significantly reduce the processing costs.
