It’s deeply rewarding when research aligns with current sectoral priorities and contributes meaningfully to ongoing policy discussions.

We are glad to share our latest study published in the Sustainability (MDPI) journal, where we characterised faecal sludge (FS) from multiple nature-based treatment systems to assess its suitability for agricultural application.

Why this matters: India currently lacks dedicated standards for treated faecal sludge. Our findings show that most FS samples meet the Fertiliser Control Order (FCO) thresholds, highlighting its potential for safe and beneficial application in agriculture.

Key findings:
1. Treatment method significantly affects faecal sludge composition.
2. Co-composting offers a relatively balanced nutrient profile, though with some variability.
3. All samples complied with Indian compost standards for most parameters

Policy recommendations:
1. Implement FSTP-level quality assurance, including batch-wise nutrient and contaminant profiling.
2. Promote FS-derived compost under the City Compost Scheme.
3. Enable co-branding with fertiliser companies to support market integration.
4. Develop FS-specific regulatory frameworks and quality benchmarks.
5. Provide certification and market development assistance to encourage adoption.

As most samples already comply with FCO norms, adopting FCO specifications as an initial benchmark for FS reuse could be a practical starting point, followed by the development of tailored standards.

This study offers evidence to support the safe application of faecal sludge in agriculture and provides actionable insights for policy and practice.

We look forward to your thoughts and feedback.
