• The government has prohibited the export of lithium-ion battery 'Black Mass' to promote domestic recycling and strengthen the availability of critical minerals in the country.

• The decision aims to recover valuable minerals from domestically available battery waste and make them available for use by domestic industries.

What is Black Mass?

• Black Mass is an important material obtained during the recycling of lithium-ion batteries. When used, lithium-ion batteries are dismantled and processed through a specialized procedure, and a black powder-like substance is obtained, which is known as "Black Mass."

It contains several important minerals and metals, including: Lithium, Cobalt, Nickel, Manganese, Copper

• These metals are valuable components used in battery manufacturing and other electrical applications.

• Thus, Black Mass serves as a secondary source of critical minerals, enabling the recovery and reuse of valuable metals from discarded batteries.

Why Has India Banned the Export of Black Mass?

• The primary objective behind this decision is to ensure better utilization of critical minerals available within the country and strengthen domestic recycling capabilities.

• It will enable the recovery of minerals such as lithium, cobalt, and nickel from used batteries within India, reducing dependence on external sources for these valuable resources.

Strategic Significance of Black Mass for India

• The use of lithium-ion batteries is increasing rapidly in electric vehicles, mobile phones, laptops, and energy storage systems.

• The manufacturing of these batteries requires critical minerals such as lithium, cobalt, and nickel. Therefore, recovering these minerals from used batteries is strategically important for India.

• Domestic recycling of Black Mass can benefit the following sectors:

1. Electric Vehicle (EV) Industry

2. Battery Manufacturing Industry

3. Energy Storage Systems

4. Domestic Supply of Critical Minerals

5. Circular Economy

Why in News?

• Swiss researchers from the University of Zurich have discovered a new method to detect Gamma-Hydroxybutyrate (GHB), commonly known as a date-rape drug, in urine.

• The new method can detect evidence of GHB consumption for up to 72 hours (3 days) after ingestion.

• This may help improve investigations into sexual assault cases.

Key Highlights

1. What is GHB?

• GHB stands for Gamma-Hydroxybutyrate.

• It is a substance that affects the central nervous system.

• It can cause unconsciousness, drowsiness and memory loss.

• It is sometimes secretly mixed into drinks to facilitate sexual assault.

2. Problem with Traditional Detection:

• GHB disappears quickly from the body.

• It is generally detectable for around 6 hours in blood and 12 hours in urine.

• This makes timely testing difficult.

3. New Discovery:

• Researchers identified a biomarker called GHB-pentose.

• It is formed when GHB interacts with a sugar-like compound in the body.

• Unlike GHB itself, this biomarker remains detectable in urine for a longer period.

1. Detection Window:

• The new biomarker may remain detectable for up to 3 days after GHB intake.

• It provides a longer period for collecting forensic evidence.

5. Significance:

• Helps improve forensic investigations.

• May support evidence collection in sexual assault cases.

• Can help investigators identify suspected drug exposure even after GHB itself disappears.
