Carbon-negative rare earth element isolation method

This technology is a green, energy-efficient method for isolating rare earth metals from biomass.

Unmet Need: Environmentally friendly critical element isolation method

Rare-earth and critical-metal elements, such as neodymium (Nd), lithium (Li), nickel (Ni), copper (Cu), and potassium (K), are critical components of clean energy technology. However, current methods for isolating these elements are energy-intensive, prone to waste contamination, and result in the release of toxic elements into the environment. New, energy-efficient metal and element isolation technologies are necessary to meet the growing demand.

The Technology: Moderate temperature and pressure element isolation method from biomass

This technology is a critical element extraction method that isolates bioaccumulated metals from biomass while producing carbon-negative hydrogen and solid carbonates. Pre-treatment of the biomass is not required. An alkaline thermal treatment at moderate temperatures and pressures is employed, and the method does not produce CO2. The isolated material can be processed for other uses. This method offers an environmentally friendly extraction method for critical elements necessary in clean energy technology.

Applications:

• Rare earth element extraction
• Critical metal extraction
• Carbon capture for utilization and storage
• Clean energy generation
• Carbonate salt production
• Hydrogen production
• Biomass conversion, specifically marine biomass

Advantages:

• Carbon-negative
• No pre-treatment
• Environmentally friendly
• Moderate temperatures and pressures
