With sessions and workshops focused on energy-efficient practices, this congress is well-positioned to foster dialogue and innovation in line with global energy awareness efforts.   Energy-efficient practices in olive oil and wine production are essential to reduce resource consumption and minimize environmental impacts. Examples of such practices are as follows:

  • Solar and renewable energy sources: Many olive oil mills and wineries install solar panels or use other renewable energy sources, such as wind or biomass, to power their facilities. This reduces the dependence on non-renewable energy and reduces carbon emissions.
  • Efficient water management: Drip irrigation systems and water recycling techniques help conserve water, which is especially important in olive cultivation because olives are often grown in arid regions. Additionally, some producers capture rainwater to reduce their reliance on external water sources.
  • Waste heat recovery: In wine and olive oil production, waste heat from processes, such as fermentation or extraction, can be captured and reused for other purposes, such as heating water or powering other parts of the production process.
  • Energy-efficient lighting and equipment: By upgrading LED lighting and investing in energy-efficient machinery, producers can significantly reduce their energy consumption. For example, modern olive oil extraction systems often have energy-efficient motors and pumps.
  • Precision agriculture: Using data-driven technologies, such as soil sensors, drones, and satellite imagery, helps optimize the use of fertilizers, water, and pesticides. This reduces not only the energy input, but also the environmental footprint of agricultural practices.
  • Anaerobic digesters for waste management: Some producers use anaerobic digesters to convert organic waste from olive pits, grape skins, or other by-products into biogas, which can then be used to generate energy for the facility. Insulation and building design: Improving insulation in storage areas and production facilities helps maintain optimal temperatures with less energy, particularly for temperature-sensitive processes such as wine fermentation.
  • Electric and hybrid vehicles: Switching to electric or hybrid vehicles for transportation within vineyards or between facilities reduces fuel consumption and emissions. Implementing these practices not only helps reduce costs and improve sustainability but also enhances the overall quality and value of the final product.

The global wine and olive oil industries have a significant impact on the environment, and their production processes often generate substantial waste and consume significant resources. However, there is growing focus on sustainability and the adoption of green technologies and practices to mitigate these environmental impacts.  One area of innovation in the wine industry is the use of alternative packaging materials, such as PET and steel, which can lead to a marked reduction in the environmental impact of wine production and distribution. The integration of digital labelling and smart farming solutions in the wine industry has yielded significant benefits in terms of sustainability and product quality. By leveraging advanced technologies, wineries have been able to drastically reduce their reliance on pesticides, decreasing their usage by up to 75%. This reduction not only minimizes the environmental impact, but also contributes to the production of healthier grapes and, consequently, higher-quality wines. The perceived quality of the final product showed an average increase of 8%, indicating that consumers recognized and appreciated the improvements brought about by these innovative approaches.

Comprehensive policy frameworks that incentivize sustainable practices and technological advancements are crucial for promoting the green transition in wine and olive oil production. The European Union’s Europe 2020 Strategy exemplifies this approach by aiming to promote smart, sustainable, and inclusive growth, which has led to an increased awareness of sustainability issues within wine and olive oil supply chains. These policies include financial incentives to adopt eco-friendly production methods, stricter regulations on resource usage and waste management, and support for the research and development of innovative technologies. In addition to policy frameworks, collaboration between industry stakeholders, research institutions, and government bodies is essential for driving green transition in these sectors. This collaborative approach can facilitate knowledge-sharing, accelerate the adoption of best practices, and foster innovation in sustainable production. For instance, partnerships between wineries, olive oil producers, and renewable energy companies can lead to the implementation of solar-powered processing facilities or the development of more efficient irrigation systems. Furthermore, consumer education and awareness campaigns can play a vital role in creating market demand for sustainably produced wine and olive oil, thereby encouraging producers to invest in green technologies and practices.

Sustainable wine production is essential for reducing environmental impacts and promoting agricultural practices that preserve natural resources.  In 2022 i published a paper in coauthory with the colleague Ferrer-Gallego discuss the potential of wine industry by-products, such as grape pomace, to not only reduce waste but also provide health benefits due to their antioxidant properties. Sustainable wine production encompasses a range of practices that aim to minimize the environmental footprint of viticulture and winemaking, while maintaining product quality and economic viability. These practices include water conservation, energy efficiency, organic farming methods, and reduction of chemical inputs. By adopting sustainable approaches, wineries can protect soil health, preserve biodiversity, and mitigate the effects of climate change. Moreover, the utilization of wine industry by-products, as highlighted in our paper, represents a significant opportunity to enhance sustainability in this sector. The valorization of grape pomace and other winemaking residues offers multiple benefits beyond waste reduction. These by-products are rich in bioactive compounds, particularly polyphenols that exhibit strong antioxidant properties. Research has shown that these compounds can be extracted and utilized in various applications, including as natural food preservatives, nutraceuticals, and cosmetic ingredients. This not only creates additional revenue streams for wineries but also contributes to the circular economy by transforming waste into valuable resources. Furthermore, the incorporation of antioxidant-rich extracts into food products or dietary supplements may offer potential health benefits to consumers, aligning with the growing trends towards functional foods and natural health products.
