Turning straw into gold: Cannabis extracts

However, more modern extraction methods like BHO, which uses a butane solvent, RSO, which uses alcohol, and the "supercritical" produced with CO2 are relatively new inventions. Steam distillers (tinctures) have been in use for about the last hundred years, and are still used today on plants such as lavender or mint, as is CO2. Get price

How Controllers Become Business Partners

Controllers are increasingly being asked to provide operational data and are increasingly being used to source business performance and customer data. The controller's staff is also assisting with self-service tools, providing others with ad-hoc reporting capabilities and enabling them to drill down to customer, employee, and transactional details.
