Why does India need bioremediation?, Pg8

Key Highlights:

• Bioremediation uses microorganisms to transform toxic substances into harmless by-products.
• India's industrialization has led to significant environmental pollution, necessitating bioremediation.
• The Department of Biotechnology (DBT) supports bioremediation projects through the Clean Technology Programme.
• Japan, EU, and China are actively using bioremediation for waste management and pollution control.
• National standards, regional hubs, and public engagement are needed for wider adoption in India.

Detailed Insights:

• Bioremediation involves in situ (on-site) and ex situ (off-site) methods, using bacteria, fungi, and algae.
• Modern bioremediation combines microbiology with biotechnology, including genetically modified microbes.
• India's diverse biodiversity offers a potential advantage with indigenous microbes adapted to local conditions.
• Challenges include a lack of site-specific knowledge, complex pollutants, and absence of unified standards.
• Bioremediation can integrate with government initiatives like Swachh Bharat Mission and Namami Gange.
• Risks associated with genetically modified organisms require strict monitoring and biosafety guidelines.
• Developing national standards, bioremediation hubs, and public awareness are crucial next steps.

Key Concepts Involved:

• Bioremediation: Using microorganisms to remove pollutants.
• In situ bioremediation: Treating contamination directly at the site.
• Ex situ bioremediation: Removing and treating contaminated material off-site.
