Pioneering Sustainable Practices in Winemaking

sustainability winemaking

The European winemaking industry is embracing sustainability by repurposing emissions and residues. Innovations include capturing CO2 from fermentation to cultivate nutrient-dense algae for animal feed and cosmetics, reducing emissions by 30% through the REDWine project, and turning grape pomace into natural health products through the NeoGiANT initiative. These projects not only reduce greenhouse gas emissions but also offer economic benefits and healthier alternatives to antibiotics, showcasing the industry’s commitment to sustainability and innovation.

How is the winemaking industry in Europe becoming more sustainable?

The European winemaking industry is embracing sustainability by repurposing emissions and residues. Innovations include:
– Capturing CO2 from fermentation to cultivate nutrient-dense algae, chlorella, for animal feed and cosmetics.
– REDWine project aims to reduce emissions by 30%, using CO2 to grow algae.
– The NeoGiANT initiative turns grape pomace into natural health products, combating antimicrobial resistance and improving animal health.

The winemaking industry is undergoing transformative changes in Europe, where innovation meets tradition in the quest for sustainability. Efforts are being made to repurpose emissions and residues from the winemaking process into valuable products, from animal feed to promising alternatives to antibiotics.

Winemaking Byproducts: From Waste to Worth

In the picturesque setting of Palmela, a wine region near Lisbon, a striking example of this innovation is unfolding. Miguel Cachão, an agronomic engineer with the Association of Wine Growers of the Municipality of Palmela, is at the forefront of a project that could revolutionize how wineries view their carbon footprint.

Harnessing CO2 Emissions

During fermentation, a winery produces significant amounts of carbon dioxide (CO2). Instead of releasing it into the atmosphere, Cachão is working on technology that captures the CO2 to cultivate chlorella, a nutrient-dense algae. This algae is not only beneficial for animal feed but also holds potential in the cosmetics industry, as well as in food supplements and even within wine production itself.

The Multifaceted Chlorella

Chlorella thrives on CO2, sunlight, and water, effectively transforming these resources into valuable biomass. Its photosynthetic efficiency and high antioxidant content make it a versatile product with a variety of applications.

Economic and Environmental Benefits

The challenges faced by winegrowers in Europe are multifold, with climate change and competition applying pressure on the industry. However, projects like REDWine, receiving EU funding under the Circular Bio-based Europe Joint Undertaking (CBE JU), promise dual advantages — additional revenue streams for wineries and a reduction in greenhouse gas emissions.

The REDWine Project

With a goal of reducing wine producers’ emissions by at least 30 percent, REDWine’s research is paving the way for a more sustainable winemaking process. By April 2025, the project aims to showcase the practicality of using CO2 for algae cultivation across wineries of various sizes.

The First Demonstration Unit

Scheduled to be operational by the end of 2023, the demonstration unit will illustrate the closed-loop process of capturing CO2 from grape fermentation and utilizing it to produce chlorella. This initiative not only mitigates carbon emissions but also generates significant economic gain for wineries.

Embracing Circular Economy in Vineyards

The wine industry’s embrace of a circular economy extends beyond just algae. Grape pomace — the skins, pulp, and seeds left after pressing — is rich in compounds that serve as natural defense mechanisms for the fruit. These substances present an opportunity to develop healthier alternatives to antibiotics.

The NeoGiANT Initiative

Another EU-funded project, NeoGiANT, is exploring grape waste’s potential to combat the growing threat of antibiotic resistance. By extracting antioxidants and eubiotics, the project aims to improve animal and fish health and resilience, reducing the reliance on traditional antibiotics.

Addressing Antimicrobial Resistance

With urgent concerns over the rise of antimicrobial resistance, the use of natural therapies from grape byproducts could revolutionize the way we approach animal health and food safety.

From Waste to Health

The end goal of projects like NeoGiANT is to introduce products derived from grape waste that offer effective treatments for common animal diseases, while also providing alternatives for preserving livestock semen.

The Promise of Innovation

As the wine industry adapts to contemporary challenges, the integration of such innovative practices reflects its commitment to sustainability. While the initial focus is on the winemaking process itself, the implications extend far into environmental conservation, animal health, and even consumer well-being.

This article is an extended version of content originally featured in Horizon, the EU Research and Innovation Magazine. It highlights the progressive steps being taken by the European winemaking industry to address environmental concerns and shows how traditional practices can evolve to meet modern sustainability standards.

Lessons Learned

The European winemaking industry is setting a strong example of how traditional practices can evolve to meet modern sustainability standards. Through innovative projects and initiatives, they are repurposing emissions and residues to create valuable products and reduce greenhouse gas emissions. Some key lessons that can be learned from these efforts are:

  1. Repurposing waste: The winemaking industry is demonstrating the potential of repurposing waste and byproducts to create economic and environmental benefits. By capturing CO2 emissions from fermentation and utilizing them to cultivate nutrient-dense algae, wineries are not only reducing their carbon footprint but also generating additional revenue streams through the production of valuable biomass.

  2. Circular economy approach: Embracing a circular economy approach, the wine industry is exploring the full potential of its resources. For example, grape pomace, which is typically discarded after pressing, is being recognized for its rich compounds that can serve as natural defense mechanisms and provide healthier alternatives to antibiotics. This approach not only contributes to environmental sustainability but also addresses urgent concerns such as antimicrobial resistance.

These lessons highlight the importance of innovative thinking and a commitment to sustainability in industries across the board. By reimagining waste as valuable resources and adopting circular economy principles, businesses can not only reduce their environmental impact but also create economic opportunities and contribute to addressing pressing global challenges.
