15 · VOC Regulation in India
How VOC emissions are regulated in India
India has no single national emission limit covering every VOC from every industry. In 2004 CCDC noted there were hardly any VOC standards beyond a few compounds such as benzene and hydrocarbons. Control still comes mainly through three routes:
- Consent to Operate. Under the Air (Prevention and Control of Pollution) Act, 1981, every plant needs consent from its State Pollution Control Board, and consent and Environmental Clearance conditions can require specific VOC-control or solvent-recovery measures.
- Sector guidelines. CPCB’s draft guidelines for the pharmaceutical industry (comments invited until 5 February 2025) propose recovering up to 95% of spent solvent, keeping losses within 5% of solvent inventory, VOC controls such as scrubbers, condensers and absorbers, and leak detection and repair. See pharmaceutical solvent recovery.
- Petroleum vapour recovery. Following a Supreme Court order in March 2023, CPCB requires vapour recovery systems at high-volume fuel outlets in large cities and at fuel storage terminals. In March 2025 the National Green Tribunal upheld ₹1 crore of environmental compensation imposed on BPCL for delays at its terminals.
What this means for your plant
Requirements are moving from simply limiting emissions towards recovering solvent — a target stated as a percentage of solvent recovered cannot be met by burning it. A recovery system meets the emission requirement and pays back through the solvent it returns, where a thermal oxidiser only adds fuel cost and CO₂. See recovery vs thermal oxidation, and the operating costs of the recovery technologies side by side. For why vent losses matter beyond compliance, see the VOC emission control problem.
