<P>This volume in our Sustainability: Contributions through Science and Technology series reviews the use of alternative green technologies (pressurized liquid and super-critical fluid extractions) for grape biomass valorization. Environmental sustainability and circular economy are discussed in relation to agro-industrial waste in the winemaking industry. The waste contaminates water and soil and, in large quantities, it has been related to bad odors, a high content of organic matter in water, and greenhouse gas emissions over the entire winemaking industry. Here, the authors illustrate how green extraction of commercially valuable substances can be scaled up at an industrial level.</P>
