Biosolids

Biosolids: It hold untapped potential for Indian agriculture, offering a cost-effective alternative to chemical fertilizers.

• About: Biosolids are solid products derived from wastewater treatment sludge and used for beneficial purposes.
• Formation Process: Wastewater treatment separates solids from liquids. The solids undergo physical and chemical treatment, forming semi-solid, nutrient-rich biosolids.
• Nutrient Content & Benefits: Contain nitrogen, phosphorus, and potassium (NPK), vital for crop production.

o Enhance soil fertility, improve crop productivity, and reduce dependence on chemical fertilizers.

o Aid in replenishing macronutrients and micronutrients in degraded soils.

o Reusing biosolids can convert waste into a valuable resource, supporting sustainable development and environmental conservation.

• Key Government Initiatives Supporting Biosolids Use:

o Swachh Bharat Mission 2.0 & AMRUT 2.0 – Focus on sustainability, hygiene, and waste management.

o Waste to Wealth Mission – Promotes resource conversion from waste, including compost, biogas, and energy.

o National Mission for Clean Ganga – Reduces pollution from untreated sewage and promotes biosolid resource recovery.
