Cryogenic Extraction of Natural Rubber
T2013-215
The Need: Advancing Sustainable Natural Rubber Production for Medical and Consumer Applications
The demand for natural rubber in industrial, medical, and consumer products is significant, but traditional extraction methods have limitations. Current approaches involve chemical defoliants or flame treatment to remove leaves, leading to environmental and health concerns. Additionally, conventional methods can damage the desirable latex content and pose risks for those with latex allergies. Therefore, there is a pressing need for a safe, efficient, and environmentally-friendly technology to extract natural rubber from plants, especially for medical devices where latex allergies are a concern.
The Technology: Cryogenic Extraction and Fracturing
The innovative technology presented in this invention offers a groundbreaking method for separating leaves from harvested plant material. It involves three main steps:
- Contacting the harvested plant material, such as Guayule, with a cryogenic liquid to embrittle the leaves.
- Applying a controlled force to the embrittled leaves, fracturing them, while preserving the branches.
- Separating the fractured leaves from the branches using various methods like agitation, vibration, filtration, and more.
Commercial Applications: Diverse Industries Benefitting from Cryogenic Extraction
The versatility of this technology opens up a wide range of applications across different industries:
- Medical Devices: Safer extraction of latex from plants like Guayule, ensuring medical products like gloves, catheters, and syringes are free from allergens.
- Industrial Products: Enhanced extraction for coatings, films, packaging materials, and other rubber-based industrial applications.
- Consumer Goods: Improved production of everyday items such as pacifiers, rubber bands, toys, and adhesives, promoting sustainability and allergen-free products.
Benefits/Advantages: Enhancing Production and Sustainability
The technology offers several key advantages that make it a game-changer in the natural rubber extraction process:
- Allergen-Free Latex: Provides a safe latex source, crucial for medical devices used by latex-sensitive individuals, ensuring patient safety.
- Environmentally-Friendly: Eliminates the need for chemical defoliants and flame treatment, reducing environmental and health concerns.
