- Winery wastewater treatment for biomolecules recovery and water reuse purposesPublication . Giacobbo, Alexandre; Oliveira, Margarida; Bernardes, A. M.; Pinho, Maria NorbertaWinery wastewater has a high pollutant load, but it also contains added-value molecules, such as phenolic compounds, which can be recovered. The recovery of these biomolecules has aroused great interest, providing benefits under different aspects, such as valorization of byproducts recovered from wastewater; reduction of the pollutant load of winery wastewater, facilitating its treatment and reuse in agriculture; reducing the environmental impacts of wineries; and promotion of the circular economy, due to the recovery of biomolecules and water reuse. Based on these matters, the chapter focuses on bringing relevant aspects about the generation of wastewater throughout the winemaking process, indicating the main biomolecules of commercial interest present in the wastewater, and proposing processes for the recovery of these biomolecules. In addition, the main technologies that are used in the treatment of winery wastewater are reported and discussed, envisaging the reuse of treated wastewater in agriculture.
- Water management toward regenerative wineriesPublication . Oliveira, Margarida; Saraiva, Artur; Lambri, M.; Rochard, J.; Fragoso, R.; Romanini, E.; Hipólito, P.; Ettore, C.; Duarte, ElizabethWine producers are now fully aware of the water-energy nexus, given the challenges created by climate change. By identifying potential environmental impacts of the wine industry, related to water and fossil energy use, wineries are taking action to improve their performance. This chapter reviews a set of technologies and strategies that can lead wineries to implement a regenerative approach, minimizing resources, recovering value from wastewater/waste, and replacing fossil energy with renewable sources. The approach is illustrated by presenting four case studies, located in three Mediterranean countries (France, Italy, and Portugal). The main conclusions are: (1) water and energy consumption ratios vary according to the wine type; (2) wastewater treatment systems tend to close the water cycle in countries facing severe water scarcity; and (3) the adoption of renewable energy in wineries is a reality today, but the adopted renewable energy depends on the region where it is located.
