Plastic Recycling Unit Pollution: Rules and Complaints

A plastic recycling unit is lawful only if it is registered as a plastic waste processor, holds consent to establish and operate from the State Pollution Control Board, runs from a site where industry is permitted, and follows the conditions on wash water, emissions, rejects and storage. Many small granule and washing units near homes do not meet one or more of these. If a unit near you is burning rejects, letting dirty wash water into the drain, filling the air with fumes at night or storing bales that could catch fire, you can complain to the State Board, the municipal body and the fire department, and take it to the NGT if nothing happens.

This guide is for residents of colonies and villages where small plastic washing, shredding, granule or pyrolysis units have come up, and for recycler owners who want to stay on the right side of the law. It covers the rules, the main sources of pollution, what evidence works and the complaint route step by step.

The essentials

Is a plastic recycling unit near homes legal?

Recycling plastic is something the law wants more of, so a recycling unit is not illegal in itself. But recycling is an industrial process, and the law expects it to happen in a permitted place, with permissions and with controls. A unit that washes, shreds, melts and extrudes plastic in a ground-floor shop in a residential lane, without consent and without treatment, is not a recycler the law protects. It is a polluting factory in the wrong place.

Three questions decide legality. Is the unit registered as a plastic waste processor and does it hold consent to establish and operate from the State Board? Is the site one where industrial activity is allowed under the master plan or zoning rules? And is it actually following the conditions of its consent on wash water, emissions, noise, storage and rejects? A unit can fail on any one of these. Some fail on all three.

Even a fully licensed unit in an industrial area is not licensed to pollute. Consent comes with conditions, and breaking them can lead to closure. So the existence of a registration certificate on the wall does not end the matter if black smoke is coming out of the shed every night.

What rules does a plastic recycler have to follow?

The Plastic Waste Management Rules, 2016, made under the Environment (Protection) Act, regulate everyone who handles plastic waste, including recyclers and other processors. Under the extended producer responsibility framework introduced in 2022, recyclers, co-processors and other plastic waste processors register on the CPCB's centralised system, report the quantities they process, and generate EPR certificates that producers and brand owners buy to meet their targets. The State Board also registers and regulates processors in its state.

Separately, a recycling unit needs consent to establish and consent to operate under the Water Act and the Air Act, like any other industry that discharges effluent or emissions. The consent category depends on the process; a simple sorting and baling unit is treated very differently from a unit that washes and extrudes, and pyrolysis is treated more strictly still. Check the current category with the board, because categories have been revised. Our guide on consent to operate explains how this works.

The Rules require recycling to follow the applicable Indian Standard and CPCB guidelines, prohibit open burning, and restrict the use of recycled plastic products for food contact except as permitted under food safety rules. Processors must keep records of what they receive and process, file returns, and send rejects that cannot be recycled to authorised routes such as co-processing in cement kilns, not to a vacant plot or a fire.

Sources of pollution in a plastic recycling unit

Most units combine several of these processes. Knowing which one is causing your problem helps you write a complaint the board can act on.

Dirty wash water in the drain outside

Post-consumer plastic arrives dirty: food residue, soil, oil, labels and glue. Washing it uses a lot of water, often with detergent or caustic, and the water that comes out is grey or black, frothy and smelly. A unit operating lawfully treats this water, recycles it where possible and discharges only within its consent limits. Units operating illegally run a pipe to the nearest drain or let it flow into a pond or field.

This is a Water Act problem and the State Board's job. When you complain, photograph the outlet if it is visible from a public place, the colour and froth in the drain at different times, and any change downstream such as dead fish or discoloured soil. If the unit uses a borewell for its water, that raises a separate groundwater question. Our guide on untreated industrial effluent complaints explains how boards sample effluent and what a sample report should contain.

Smoke, fumes and smell from extruders and burning

Heated plastic gives off fumes that residents describe as sharp, sweet or chemical. A unit with proper hoods, ventilation and controls keeps this mostly inside; a unit in a cramped shed with the shutter half down sends it straight into neighbouring homes. Night-time operation, when inspections are unlikely, makes it worse. Odour is harder to measure than smoke, but boards do act on consistent, well-documented complaints; see our guide on industrial odour complaints.

Burning is the clearest violation. Rejects, wires stripped from scrap, sweepings and unusable plastic are sometimes burnt behind the unit or on a nearby plot, producing thick black smoke. Open burning of waste is prohibited and is straightforward to prove with a video. Pyrolysis units, which heat plastic or tyres to produce oil, are a special concern: they need consent and must meet CPCB norms, and badly run units have been the subject of repeated complaints and tribunal attention.

Shredders and granulators running at night

Shredders, granulators and grinders are loud, and small units often run them into the night to finish a day's lot. The Noise Pollution (Regulation and Control) Rules, 2000 set ambient limits by zone: 55 dB(A) by day and 45 dB(A) at night in residential areas, against 75 and 70 in industrial areas. Night here means 10 pm to 6 am. A unit operating in a residential lane is measured against the residential limit, which machinery of this kind will almost always exceed.

For noise at night, the police are the quickest practical response, and repeated calls create a record. The SDM can also act on the nuisance, and the State Board can include noise in its inspection. A phone decibel app is not proof, but a series of readings with videos helps show the pattern and persuades officials to take their own measurements.

Fire risk and recycling units in residential areas

Plastic burns hot and fast, and recycling units often store large quantities in bales, sacks and loose heaps, sometimes on rooftops or in lanes too narrow for a fire tender. Add illegal electrical connections and machines running for long hours, and the risk to neighbours is obvious. The fire department can inspect and act under the state fire services law, and a complaint that focuses on fire risk often gets a faster response than one about smell.

Many small units operate in urban villages, unauthorised colonies or residential plots where industrial use is not permitted. That is a land-use violation the municipal body or development authority can act on by sealing, quite apart from pollution law. Boards in Delhi NCR have also carried out drives against units running in non-conforming areas. Our guide on illegal change of land use causing pollution covers that route.

What to collect before you complain

How to complain about a polluting plastic recycling unit

What the State Board and the NGT can do

After an inspection, the board can issue a show-cause notice, direct closure and disconnection of power and water under section 33A of the Water Act, section 31A of the Air Act or section 5 of the EP Act, and levy environmental compensation using its formula-based method. For a unit running without consent in a residential area, closure is a common outcome. For a licensed unit breaking conditions, the board more often directs specific improvements, with closure if they are not made.

If the board does not act, or acts and the unit reopens a few weeks later, the NGT can hear the matter under section 14 of the NGT Act. It often forms a joint committee to inspect and report, then directs the authorities to act, orders compensation under the polluter pays principle and sometimes asks for compliance reports at intervals. Residents who suffered loss can claim compensation under section 15 within five years.

In cases Advocate B.K. Singh has handled against small polluting units in urban villages, the step that made the difference was getting the municipal body and the board to act together. A board closure alone is often defeated by the unit quietly shifting two lanes away; sealing for land-use violation, together with disconnection, tends to be harder to undo.

What if the unit has all its papers?

Sometimes the RTI reply shows that the unit has consent, is registered and sits in a notified industrial area that happens to adjoin a colony. In that case, asking for closure because the unit exists is unlikely to succeed. The better course is to read the consent order closely, note the conditions on wash water treatment, emission controls, working hours, storage and rejects, and complain about the specific conditions being broken, with evidence for each.

Boards respond better to 'the consent requires a closed shed and treated discharge, and here are three weeks of videos showing an open shed and grey water in the drain' than to a general plea that the factory should go. If the board inspects and finds compliance on the day, keep logging; a pattern of night-time violations, documented over months, is what eventually persuades the board or a tribunal committee to make an unannounced visit.

Recyclers and EPR certificates: why the paperwork matters

Registered plastic waste processors generate EPR certificates based on the plastic they actually process, and producers buy these to meet their obligations. That gives recyclers a financial reason to report large quantities, and gives the CPCB and boards a reason to check whether reported processing matches real capacity, electricity use and output. Processors whose records do not add up risk suspension of registration and cancellation of certificates.

This matters to neighbours in two ways. First, a unit claiming registration as a processor is subject to verification and audit, so a complaint about how it really operates can feed into those checks. Second, a unit that is not registered at all cannot lawfully sell certificates, which means it is outside the system the Rules set up. Producers buying certificates should read our guide on EPR certificates and target shortfall.

If you run a recycling unit: getting and staying compliant

If your unit is in a residential or non-conforming area, the long-term answer is to move to a permitted industrial site; no amount of paperwork will make a washing and extrusion line lawful in a residential lane. In a proper site, get consent before starting, register as a processor, install wash water treatment and recirculation, put hoods and controls on extruders, keep bales covered and away from boundaries, and send rejects to co-processing or other authorised routes with records.

When a notice arrives, reply in time and with documents, and fix what can be fixed before the hearing. A closure direction can be appealed to the NGT within 30 days of communication, but revocation after showing compliance is often faster; see our page on closure notice replies. Recyclers handling e-waste or batteries as well as plastic need separate registrations under those rules.
