In the heart of winemaking, a valuable resource often goes overlooked: wine lees. This byproduct, composed of yeast cells, grape fragments, and other organic matter, traditionally ends up as waste. However, CD BioSciences recognizes the potential within this seemingly discarded material. We offer innovative wine lees recycling services, transforming this residue into a range of valuable products through cutting-edge technology. This not only minimizes environmental impact but also unlocks economic benefits for wineries and contributes to a circular economy.

What are Wine Lees
Wine lees are the sediment that settles at the bottom of fermentation vessels during winemaking. Primarily composed of dead yeast cells, grape skins, seeds, and tartrates, lees were historically discarded as waste. However, advancements in technology and a growing focus on sustainability have revealed the hidden potential of this byproduct.
The Problem with Traditional Wine Lees Disposal
Traditional disposal methods for wine lees, such as landfilling or direct application to soil, pose several environmental challenges:
- Landfill Strain: Large volumes of wine lees contribute to landfill overcrowding and leachate production.
- Soil and Water Contamination: Direct application can lead to soil acidification, nutrient imbalances, and potential water contamination.
- Greenhouse Gas Emissions: Decomposition of organic matter in landfills releases methane, a potent greenhouse gas.
Our Solution: Wine Lees Recycling
Our company offers a comprehensive suite of wine lees recycling services, transforming this waste stream into valuable products. Our approach is grounded in advanced technologies and a commitment to sustainability, offering a win-win solution for both wineries and the environment.
Technology & Processes
We employ a variety of technologies to process wine lees and extract valuable components, including:
- Mechanical Separation: This involves techniques like filtration, centrifugation, and pressing to separate solid and liquid fractions of the lees. This allows for targeted processing of different components.
- Biotechnological Processes: We utilize fermentation and enzymatic hydrolysis to break down complex organic matter in wine lees, releasing valuable compounds like mannoproteins, polysaccharides, and organic acids.
- Thermal Treatments: Controlled heating processes, such as pyrolysis and gasification, are used to convert wine lees into biochar, bio-oil, and syngas, which can be used as fuel or further processed into other valuable products.
Technical Advantages
- High Efficiency: We achieve high extraction yields of valuable compounds from wine lees, maximizing resource recovery.
- Environmental Friendliness: Our processes minimize waste generation and environmental impact, aligning with sustainable practices.
- Flexibility: We can tailor our services to specific winery needs and the characteristics of their lees.
- Cost-Effectiveness: Our solutions offer a cost-competitive alternative to traditional disposal methods, while generating valuable products.
Categories of Wine Lees Recycling Technologies
- Material Recovery: This focuses on extracting valuable components from wine lees, such as tartaric acid, mannoproteins, and yeast extracts, for use in various industries.
