Comprehensive Overview

ETP chemical sludge, biological sludge, paint sludge, and incinerator ash must be analyzed before disposal into TSDF landfills or cement kiln co-processing. We perform Toxicity Characteristic Leaching Procedure (TCLP), heavy metal screening, moisture measurement, and gross calorific value (GCV) determination in accordance with CPCB hazardous waste guidelines.

Applicable Regulatory Standards & Testing Protocols

✓ Hazardous Wastes Rules 2016 (Schedule II & Toxicity Criteria) ✓ USEPA Method 1311 (TCLP Leaching Procedure) ✓ IS 1350 (Methods of Test for Coal and Coke / Waste GCV)

Analyzed Parameters & Test Methods

TCLP Leachate Heavy Metals (Pb, Cd, Cr, Hg, As, Ba, Se)

Moisture Content (%) & Total Solid Concentration (%)

Gross Calorific Value GCV (kcal/kg)

Loss on Ignition (LOI at 550°C)

pH & Electrical Conductivity of Waste Extract

Total Organic Carbon (TOC) & Oil & Grease %

Sample Intake & Turnaround Protocol

1 kg Solid Sludge / Slurry Sample in Sealed Polybag | Turnaround Time: 5 - 7 Working Days

Key Scope & Execution Deliverables

TCLP report for securing TSDF landfill manifest approval

Assessment of GCV for waste-to-energy and cement kiln co-incineration suitability

Schedule II hazardous waste concentration criteria verification

Filterability and cake dryness evaluation for decanter centrifuges and filter presses

Key Business & Regulatory Benefits

Safely determines whether sludge is hazardous or non-hazardous

Reduces TSDF disposal tipping fees by identifying co-processing options
