Topic 2 – Targeting secondary sources to enhance access to raw materials
greenLi is seeking to join or help form an international consortium for RAMP Joint Call 2026 – Topic 2, focused on recovering critical raw materials from secondary sources and reintegrating them into high-value supply chains.
greenLi is developing complementary technologies that can contribute to a circular lithium value chain by recovering lithium from aqueous secondary streams and converting recovered lithium into new battery materials. We are particularly interested in projects addressing lithium-bearing industrial waste and wastewater, battery-recycling streams, and other secondary aqueous resources.
Direct Cathode Manufacture (DCM) – TRL 3: An emerging downstream electrochemical process designed to capture lithium from an aqueous lithium-bearing stream and transfer it directly into cathode active material. Within a secondary-resource value chain, DCM offers the potential to use recovered lithium as an input for new battery materials while reducing intermediate processing steps. This creates a potential pathway from recovered lithium directly to high-value cathode active material for reintegration into the battery supply chain.
Membrane Lithium Extraction (MLE) – TRL 4: A modular membrane-based system for selectively extracting and concentrating lithium from aqueous resources. For Topic 2, MLE can potentially be applied to lithium-bearing industrial waste and wastewater, battery-recycling streams, and other secondary aqueous streams where selective lithium recovery or concentration is required. MLE is designed for continuous, modular scale-up using commercial-off-the-shelf reverse-osmosis hardware.
The technologies can be deployed independently or in tandem and integrated with complementary recovery, separation and processing technologies developed by consortium partners.
We are particularly interested in collaborating with organizations working in battery recycling and secondary raw-material recovery; industrial operators generating lithium-bearing waste or wastewater; complementary extraction, separation and processing technology developers; cathode and battery-material manufacturers; process and pilot-scale engineers; research organizations; and partners providing materials characterization, LCA/TEA, validation and industrial demonstration capabilities.
Our objective is to develop a complementary consortium capable of demonstrating a more circular pathway in which lithium is recovered from secondary resources and reintegrated into the battery-material supply chain, with the potential to progress from lithium-bearing waste streams to newly manufactured cathode active material.
greenLi Extraction Technologies Ltd. is an Israeli critical-minerals technology company developing innovative solutions for recovering lithium from aqueous resources and converting it into high-value materials for the battery supply chain.
greenLi’s technology originated from research at Tel Aviv University’s Water & Energy Lab and combines expertise in environmental engineering, membrane science, electrochemistry, process engineering and battery materials. The company is developing two complementary technology platforms: Membrane Lithium Extraction (MLE), a selective membrane-based process for recovering and concentrating lithium from aqueous sources; and Direct Cathode Manufacture (DCM), an emerging electrochemical process designed to transfer recovered lithium into cathode active material.
MLE is based on greenLi’s proprietary lithium-selective membrane technology and is designed as a continuous, modular process compatible with commercial reverse-osmosis hardware and existing water- and process-stream infrastructure. DCM extends the platform downstream, creating a potential pathway for lithium recovered from primary or secondary aqueous streams to be converted into new battery materials.
greenLi combines scientific research with in-house engineering, electrochemistry, intellectual-property and commercialization capabilities. Its multidisciplinary team includes specialists in environmental and water engineering, selective membranes, mechanical and process engineering, electrochemistry and cathode materials, supported by senior expertise in industrial infrastructure, project development and international partnerships.
For circular raw-material applications, greenLi aims to complement established recycling and materials-recovery technologies rather than replace them. By coupling selective lithium recovery with downstream cathode manufacture, the company is developing a potential pathway for recovered lithium to move beyond commodity recycling and be reintegrated directly into higher-value battery materials, supporting more circular and resilient lithium supply chains.
