Hazardous Waste Testing Laboratory India | NABL Accredited

Auriga Research is a NABL-accredited hazardous waste testing laboratory providing comprehensive waste characterisation and classification services per the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016. Our testing determines whether industrial waste streams qualify as hazardous based on toxicity, flammability, corrosivity, and reactivity characteristics.

We perform TCLP (Toxicity Characteristic Leaching Procedure), heavy metal analysis, flash point determination, pH/corrosivity testing, calorific value, oil and grease content, and complete physicochemical characterisation required for CPCB compliance, TSDF acceptance, and waste disposal authorisations.

Hazardous Waste Testing Parameters

TCLP — Toxicity Characteristic Leaching Procedure (US EPA 1311)
Heavy metals — As, Ba, Cd, Cr, Pb, Hg, Se, Ag by ICP-MS/AAS
Flash point — Pensky-Martens closed cup method
pH and corrosivity — electrometric method
Calorific value — bomb calorimeter
Oil and grease content — partition gravimetric method
Total organic carbon (TOC)
Cyanide and sulfide (reactivity testing)
PCBs and organochlorine pesticides by GC-ECD

Who Needs Hazardous Waste Testing

Chemical and pharmaceutical manufacturers generating process waste
TSDF operators requiring waste acceptance characterisation
Industries applying for hazardous waste authorisation from SPCB
E-waste recyclers and dismantlers
EIA consultants assessing waste management plans

Turnaround Time

Standard hazardous waste characterisation including TCLP and physicochemical parameters takes 10-12 business days. Flash point and pH results are available within 3-5 days. Comprehensive waste classification reports are delivered within 15 business days.

Frequently Asked Questions

What tests classify waste as hazardous under Indian regulations?

Under the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016, waste is classified as hazardous based on characteristics including toxicity (TCLP leachate analysis), flammability (flash point below 60 deg C), corrosivity (pH below 2 or above 12.5), and reactivity (cyanide or sulfide content). CPCB Schedule I and II list specific waste categories. TCLP testing per US EPA Method 1311 determines if leachable metals exceed regulatory thresholds.

What is TCLP testing and why is it required?

Toxicity Characteristic Leaching Procedure (TCLP) simulates landfill conditions by extracting contaminants from waste using an acetic acid solution. The leachate is analysed for 8 heavy metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver) and organic compounds. If any analyte exceeds regulatory limits, the waste is classified as hazardous. TCLP is mandatory for waste disposal authorisation and TSDF (Treatment, Storage and Disposal Facility) acceptance.

How should hazardous waste samples be collected and sent for testing?

Samples must be collected in chemically inert containers (HDPE or glass) appropriate to the waste matrix. Volatile samples require zero-headspace containers. Each container must be labelled with waste description, source, date, and sample ID. Chain of custody documentation must accompany all samples. We provide sampling guidance and can arrange field sampling by our trained technicians for complex waste streams.
