Circular Economy in Agriculture: Waste to Wealth

Context:

India is promoting a circular economy in agriculture by converting agricultural waste into energy, organic inputs, and economic value — aligning environmental sustainability with rural development.

What is Circular Economy in Agriculture?

A system that treats waste as a resource, not a disposal problem.

Core Principles (6Rs)

• Reduce
• Reuse
• Recycle
• Refurbish
• Recover
• Repair

Goal: Keep materials in use, minimise resource extraction, and eliminate waste.

Types of Agricultural Waste

1. Crop residues / stubble → often burned, causing pollution.
2. Animal manure and carcasses → requires safe disposal and reuse.
3. Post-harvest losses → quantity and quality losses in supply chain.
4. Food waste → from retail and households.

Value Conversion Technologies

• Biomass energy
• Organic fertilisers
• Biogas production
• Biochar / engineered biochar (soil fertility + carbon sequestration)

Major Government Initiatives

1. GOBARdhan Scheme

• Converts dung, crop residues, and food waste into:
  • Compressed biogas (CBG)
  • Organic manure
• Supported by carbon credits, tax incentives, and digital portal.

2. Crop Residue Management (CRM)

• Promotes in-situ and ex-situ residue use.
• Reduces stubble burning.
• Improves soil health and farm productivity.

3. Agriculture Infrastructure Fund (AIF)

• Credit support for post-harvest infrastructure.
• ₹66,000+ crore sanctioned across projects like:
  • Warehouses
  • Cold storage
  • Processing units

4. Animal Husbandry Infrastructure Development Fund (AHIDF)

• ₹15,000 crore fund.
• Supports dairy, meat processing, and waste-to-wealth systems.

5. Water Reuse Initiatives (Jal Shakti)

• Treated wastewater used for agriculture and landscaping.
• Promotes water conservation and groundwater recharge.

Link to Sustainable Development Goals (SDGs)

Circular agriculture supports:

• SDG 2: Food security and sustainable farming
• SDG 12: Responsible consumption
• SDG 13: Climate action

Helps address 1.05 billion tonnes of global food waste (2022).
