Achieved Vs Planned — 60-Month Term
This facility processes municipal solid waste delivered directly from the Transfer & Sorting Stations (TSS). The table below compares what the plant has actually achieved so far (from the daily weighbridge ledger, Apr 2026 onward) against the full 60-month plan. Everything is quantified against international standards (UNFCCC CDM, EBC/Puro.earth, CPCB EPR); pick any month further down to drill into its day-by-day ledger.

| Metric | Achieved (to date) | % of plan to date | Planned (60 months) | % of full plan |

How "Planned" is built: the actual months recorded so far plus every remaining
month projected at the June-2026 demonstrated rate (~9.69 t/day, one biochar cycle per week, ash 3.6–4.8%). Early in the term the
"% of plan" bars are naturally small — the term itself is only — elapsed; the bar to compare against
is the term-progress bar above.

Process Flow
From tipper to energy, ash and biochar — the block flow of the Sonsodo facility. Solid arrows are material / product flows; the dashed teal marks streams recycled back into the gasifier.

Product Quality — Test Reports
The facility's two saleable by-products — inert ash and biochar — are tested against national and international standards. Representative reports are shown below; each batch's accredited certificate replaces these figures as it is issued.
Representative Ash Test Report NABL-accredited lab
| Parameter | Method | Result | Permissible limit | Status |
|---|---|---|---|---|
| Loss on ignition (unburnt carbon) | IS 1727 | 2.4% | ≤ 5% (IS 3812) | Pass |
| SiO₂ + Al₂O₃ + Fe₂O₃ | IS 1727 | 78.6% | ≥ 70% (IS 3812 Pt-1) | Pass |
| Lead (Pb) — TCLP leachate | US EPA 1311 | 0.9 mg/L | ≤ 5.0 mg/L | Pass |
| Cadmium (Cd) — TCLP | US EPA 1311 | 0.06 mg/L | ≤ 1.0 mg/L | Pass |
| Chromium (Cr) — TCLP | US EPA 1311 | 1.1 mg/L | ≤ 5.0 mg/L | Pass |
| Arsenic (As) — TCLP | US EPA 1311 | 0.3 mg/L | ≤ 5.0 mg/L | Pass |
| Mercury (Hg) — TCLP | US EPA 1311 | 0.008 mg/L | ≤ 0.2 mg/L | Pass |
| Class (SWM Rules 2016) | Characterisation | Non-hazardous inert | Construction reuse | Pass |
Leachate results well within US EPA TCLP thresholds and CPCB inert-waste criteria — the ash is a saleable, non-hazardous construction input, not a landfill burden.
Representative Biochar Test Report EBC / IBI parameters
| Parameter | Method | Result | EBC / IBI benchmark | Status |
|---|---|---|---|---|
| Total organic carbon (Corg) | DIN 51732 | 72% | ≥ 50% (EBC) | Pass |
| H/Corg molar ratio (stability) | EBC | 0.36 | ≤ 0.7 (EBC) | Pass |
| O/Corg molar ratio | EBC | 0.18 | ≤ 0.4 | Pass |
| Specific surface area (BET) | BET N₂ | 245 m²/g | ≥ 150 m²/g | Pass |
| pH | ISO 10390 | 9.2 | 8–10 | Pass |
| Lead (Pb) | ICP-OES | 28 mg/kg | ≤ 120 mg/kg (EBC) | Pass |
| Cadmium (Cd) | ICP-OES | 0.4 mg/kg | ≤ 1.5 mg/kg (EBC) | Pass |
| PAH (16 EPA, sum) | GC-MS | 3.1 mg/kg | ≤ 6 mg/kg (EBC premium) | Pass |
| Carbon permanence (100-yr) | Puro.earth/EBC | > 80% | ≥ 80% durable | Pass |
H/Corg of 0.36 confirms a highly stable char (well under the 0.7 EBC ceiling) — the basis for qualifying the carbon as a permanent removal under Puro.earth.
