Authorized Recovery & Disposal of Solvents & Organic Waste
Secure management for Methylene Chloride, Toluene, and Spent Mother Liquor. 100% Traceable via Form 10 Manifests & GPS per HOWM Rules, 2016.
The Mixing Trap
Mixing Halogenated (MDC) with Non-Halogenated solvents? You risk rejection at cement kilns and immediate SPCB closure notices due to infrastructure damage risks.
80-90% Recovery
Fractional Distillation Efficiency
Form 10 Chain
100% Traceable Manifests.
High-Calorific Value Liquid Organic Wastes
This category encompasses high-volatility liquid streams generated primarily by pharmaceutical (API), pesticide, and chemical manufacturing. Proper classification is critical to distinguish between recyclable resources (via distillation) and destructible liabilities.
Regulatory Classification
Process-Based
Items 28 (Solvents) & 29 (Pesticides) of HOWM Rules, 2016
Characteristics-Based
Class C (Flammable) or Toxic constituents
Halogenated Solvents
Methylene Chloride (MDC), Chloroform, Trichloroethylene (TCE), Carbon Tetrachloride.
Non-Halogenated Solvents
Acetone, Toluene, IPA, Methanol, Xylene, Ethyl Acetate, Hexane, Cyclohexane.
Distillation Residues
Still bottoms, Tarry residues, Spent mother liquor (API Pharma).
Process Wastes
Organic residues from pesticide manufacturing, Phenolic waste.
Regulatory Tripwires
Governed strictly by HOWM Rules, 2016. Ignorance is not a defense against NGT fines.
Storage Violations
Standard hazardous waste storage is 90 days. However, high-velocity solvent streams often trigger stricter fire safety limits:
AUTHORITY ALERT
Strict 7-Day Storage Limit
For specific high-flashpoint solvents exceeding 25% annual capacity.
The Mixing Prohibition
Mixing Halogenated (e.g., Chloroform) with Non-Halogenated (e.g., Acetone) is a critical failure.
- Ruins 90% recovery potential (azeotrope formation)
- Damages cement kiln infrastructure (corrosion)
- Leads to immediate load rejection & penalties
INCOMPATIBILITY
Do Not Mix: Oxidizers (e.g., Nitric Acid) with Organic Solvents. This is the #1 cause of exothermic fires in tankers.
VAPOR PRESSURE
High-volatility solvents (MDC) need pressure-rated tanks. Standard drums may "bloat" or leak in Indian summers.
STATIC SAFETY
All drums/tankers must be grounded/bonded during transfer. Static discharge is a silent ignition source.
The KLIN ENVIRO Protocol

- Vermiculite-lined drums for "Lab Packs" (R&D waste)
- Form 8 Labels (Flammable/Toxic)
Transport Documentation

- Form 9 (TREM Card): Chemical-specific emergency guide for drivers.
Treatment & Valorization
Fractional distillation for Acetone, Toluene (80-90% purity).
Still Bottoms/Tars blended as AFR for cement kilns.
Halogenated/Toxic residues sent to CHWIF.
Technical FAQs
Can I send mixed solvents for recovery?
It is highly recommended to segregate solvents at the source. Mixed solvents (azeotropes) require complex separation techniques like pressure-swing distillation, which increases treatment costs and drastically lowers your recovery yield credit.
What is the difference between Schedule I and Schedule II?
Schedule I identifies waste based on the process (e.g., 'Distillation residue from organic chemical manufacturing'). If your waste isn't listed there but has hazardous characteristics like flammability (Flash point <60°C) or toxicity, it falls under Schedule II (Class C).
How do you handle 'Spent Mother Liquor' from API manufacturing?
Mother liquor often contains valuable dissolved products. We assess it for 'Chiral Resolution' recovery first. If unviable, its high calorific value makes it an ideal specific candidate for co-processing in cement kilns as fuel.
Why is the 'Blue Copy' of the manifest important?
The Blue Copy (Copy 6) is the official 'Certificate of Disposal' returned by the TSDF/Recycler. It is your only legal proof that liability has ended. KLIN ENVIRO expedites this return process for you.
What if my distillation residue contains high Chlorine?
High chlorine (>1.5%) wastes cannot usually be co-processed in cement kilns as they cause internal corrosion. These must be segregated and sent for high-temperature incineration at a authorized CHWIF.
