Providing a new direction for DIRECT
LITHIUM
EXTRACTION

Avonlea has adapted its’ patent-pending hydrodynamic cavitation reactor, proven over several years of industrial water treatment, for the extraction of lithium from brine water.

The ACCELi process utilizes controlled hydrodynamic cavitation to produce an extreme energy release at the microscopic level. This process generates thousands of micro bubbles/second to form, releasing molecular bonding energy.  This energy release combined with tailored chemical input, provides an avenue for desired elements to combine and drop out of solution.

Avonlea system takes “off the shelf” components and combines them in concert with its’ bank of hydrodynamic cavitation reactors in a 6000 barrel / day module. The process is easily expanded and duplicated adding capacity quickly and cost-effectively.

Producing little to no waste, industrially pure products generated through the ACCELi process include;

Mg(OH)2, CaCO3, Sr2(PO4) and Li3PO4 (or Li2CO3). Other products may be produced as well depending on the brine composition.

 Avonlea Environmental Technologies Advances Sustainable Lithium Extraction Pilot in Pennsylvania

Northeast, PA – Avonlea Environmental Technologies is pleased to announce the ongoing progress of its innovative lithium extraction pilot project in Northeast Pennsylvania, showcasing a sustainable approach to critical mineral recovery.

The pilot program utilizes cutting-edge ACCELi direct lithium extraction technology to recover lithium and other valuable minerals from wastewater brine produced during natural gas operations in the Marcellus Shale Formation. This initiative is hosted at Kendra II’s Springville water transfer site.

By repurposing wastewater that would otherwise be discarded, Avonlea Environmental Technologies’ process extracts lithium, magnesium, calcium, strontium, and other minerals. The extracted materials are expected to yield industrial-grade products, contributing to sustainable resource management and economic development.

The pilot program is designed to process approximately 20,000 liters of brine daily. Data collected during this trial will be independently verified to ensure accuracy and reliability. This effort marks a significant step toward establishing environmentally responsible commercial lithium production in North America.

Avonlea Environmental Technologies’ sustainable approach aligns with the growing demand for domestic lithium supplies and supports Pennsylvania’s emergence as a hub for critical mineral innovation.

Avonlea Environmental Technologies Unveils Cavitek – A Groundbreaking Advancement in Sustainable Lithium Mining

Calgary, Alberta – April 23, 2025  – Avonlea Environmental Technologies, a leader in eco-innovative industrial solutions, today announced the launch of Cavitek, a revolutionary new technology that promises to transform lithium extraction through advanced cavitation science. With the global demand for lithium surging due to the rise of electric vehicles and renewable energy storage, Cavitek introduces a faster, more energy-efficient, and environmentally responsible method of lithium mining.

At the heart of Cavitek lies a patented process harnessing controlled cavitation—a phenomenon where a localized pressure drop within a liquid causes the formation of microbubbles. These microbubbles become unstable and implode upon themselves releasing intense energy, at the  molecular-level in the form of high temperature and high pressure shock waves, imposing powerful physical and chemical interactions.

Avonlea’s Cavitek system generates thousands of these micro-cavitations every second, precisely calibrated to initiate targeted chemical reactions, dismantle stable emulsions, and enhance fluid-gas-solid interactions. Unlike conventional extraction methods, which often rely on harsh chemicals, high temperatures, or lengthy processing times, Cavitek achieves rapid and efficient lithium release from complex mineral structures with minimal environmental impact.

“We’ve engineered a platform that applies science at the molecular level to drive real-world industrial transformation,” said Douglas Brett, President at Avonlea Environmental Technologies. “Cavitek is not only a leap forward for the critical mineral extraction sector but also a win for sustainability—delivering unprecedented efficiency without compromising environmental stewardship.”

Key benefits of Cavitek include:
• Enhanced extraction efficiency with drastically reduced processing time
• Lower energy consumption compared to thermal or chemical methods
• Reduced chemical usage, minimizing environmental footprint
• Scalable design adaptable for various mining and industrial applications

Cavitek represents Avonlea’s commitment to advancing next-generation technologies that align resource extraction with ecological responsibility. As lithium remains a critical component in the global energy transition, Avonlea’s innovation marks a pivotal step toward cleaner, smarter, and more sustainable mining solutions.

The process is modular, cost-effective, and capable of scaling quickly to meet increasing demand for lithium—a critical mineral for electric vehicles and energy storage systems.

Technical Features of ACCELi Technology

• Hydrodynamic Cavitation Reactor: Proven in industrial water treatment applications, the reactor generates extreme energy at the microscopic level by creating and collapsing microbubbles. This molecular-level shockwave drives efficient separation of lithium ions from brine.
• No Freshwater Requirements: Unlike conventional methods, ACCELi operates without consuming freshwater and recycles treated brine back into reservoirs.
• Integrated Heat Generation: The process generates heat through cavitation rather than requiring external input, reducing energy costs.
• Multi-Product Output: In addition to lithium extraction, ACCELi produces saleable by-products such as magnesium hydroxide (Mg(OH)₂) and calcium carbonate (CaCO₃), and strontium carbonate (SrCO3) maximizing resource utilization and profitability.
• High Purity Lithium Phosphate: The system achieves over 97% purity for Li₃PO₄ without additional steps, enabling downstream refinement into battery-grade materials like lithium iron phosphate (LFP).

Scalability and Efficiency

Avonlea’s ACCELi system utilizes off-the-shelf components integrated with its hydrodynamic cavitation reactors to deliver a modular setup capable of processing up to 6,000 barrels per day. This design allows operators to expand capacity rapidly and cost-effectively, making it ideal for both pilot-scale and commercial-scale projects.

Applications for Oil, Gas, and Lithium Industries

Avonlea’s expertise in hydrodynamic cavitation extends beyond lithium extraction into oilfield operations:

• Breaking Heavy Emulsions: Cavitek technology efficiently separates frac flow-back fluids into clean sales oil and reusable produced water with minimal waste.
• Residual Crude Recovery: Operators can maximize oil recovery from produced water while reducing chemical costs and improving injection well performance.
• Water Treatment for Reuse: Real-time treatment programs supercharge biocide effectiveness and reduce retention time, lowering overall operating costs.

Supporting ESG Goals

With zero waste production and reduced water usage, ACCELi aligns with environmental, social, and governance (ESG) priorities across industries. Its compact equipment footprint further supports sustainable operations by minimizing site impact.
