1. Pressurized Fluid Extraction : A Sustainable Technique with Added Values
Abstract : The challenge for the future was defined by the Brundtland Commission (1987) and by the Rio Declaration (1992), in which the fundamental principles for achieving a sustainable development were provided. Sustainable chemistry can be defined as the contribution of chemistry to the implementation of the Rio Declaration. READ MORE
