The last diya has flickered out. The sweets have been shared, the celebrations have quietened, and the colourful lights that once illuminated balconies, windows and doorways are finally switched off. Some are carefully untangled and packed away for another year. Others, with a broken wire, a missing bulb or a faulty connection, are thrown into the nearest dustbin. Within days, the festive glow disappears, but the story of those discarded lights is only beginning.
Every Diwali, decorative lighting becomes an important part of the celebrations. From delicate fairy lights and flashing LED strings to elaborate electronic decorations, households find new ways to brighten their surroundings. Yet, amid the excitement of decorating and buying new lights, one question often goes unnoticed: what happens to these decorations once the festival is over?
The answer brings us to an environmental concern that deserves more attention: electronic waste, commonly known as e-waste.
The hidden cost behind the festive glow
Decorative lights may appear harmless, but their construction involves several materials. Depending on their design, many contain plastic insulation, metal wiring, LEDs and electronic components. These materials require resources and energy to manufacture. When the lights stop working, they do not simply disappear.
Unlike traditional decorations that can be reused or disposed of through ordinary household practices, electronic lighting needs more careful handling. Damaged wires, circuit boards and other components can become part of the growing e-waste stream. When mixed with everyday rubbish, they may end up in landfills or enter informal waste-handling channels where materials are not always recovered safely.
The scale of the wider problem is already concerning. According to the United Nations’ Global E-waste Monitor 2024, the world generated approximately 62 million tonnes of electronic waste in 2022. Only 22.3 per cent was documented as formally collected and recycled. The report also recorded 1.9 million tonnes of discarded lamps globally, of which only around five per cent was documented as formally collected and recycled. These figures cover wider categories of electronic and lighting waste, not Diwali decorative lights alone, but they highlight the challenges of responsible disposal.
India faces a similar challenge. According to figures shared by the Ministry of Environment, Forest and Climate Change in Parliament, the country generated approximately 1.39 million tonnes of e-waste during the financial year 2024–25. The reported figure for collection, dismantling and recycling or disposal was 70.71 per cent. However, there is no separately established national estimate of decorative lighting waste generated specifically after Diwali.
When festive purchases become short-lived waste
One reason decorative lighting contributes to waste is the habit of treating it as a seasonal purchase rather than a long-term household item. New designs, changing colours and attractive prices encourage people to replace decorations even when their existing lights are still functional.
Sometimes, a single faulty bulb or a loose connection leads to an entire string being discarded. Buying a replacement can seem easier than repairing an old one. Gradually, this creates a cycle of purchasing, using and throwing away that continues beyond the festive season.
The problem is not the celebration itself, but the unnecessary consumption surrounding it. Enjoying Diwali should never mean overlooking the environment that makes our celebrations possible.
Giving old lights a second life
A more sustainable Diwali begins with a simple change in perspective: decorations do not have to be disposable.
Before purchasing new lights, take a look at the ones stored away from previous celebrations. Clean them, check their connections and see whether minor repairs are possible. If they are still working safely, there is little reason to replace them simply because a new design has arrived.
Choosing good-quality, energy-efficient LED lights can also make a difference. LEDs generally consume less electricity than traditional incandescent lighting. Choosing durable products from reliable manufacturers, rather than making decisions based solely on price, can help reduce frequent replacements.
There is also beauty in exploring decorations that do not depend entirely on electricity. Earthen diyas, reusable lanterns, paper decorations and natural materials can bring warmth and character to festive spaces. These alternatives can complement electronic lighting while reducing the need to purchase new electrical decorations every year.
Most importantly, when decorative lights become irreparable, they should not be mixed with ordinary household rubbish. Keep them separate and hand them over to an authorised e-waste collection centre, recycler or appropriate take-back programme. Avoid burning wires or dismantling electronic components at home, as improper handling can create environmental and health risks.
Sustainable celebrations are not about giving up the things that make festivals special. They are about finding ways to enjoy them without creating unnecessary waste.
Families can make sustainability a shared festive activity by checking old decorations together, choosing reusable alternatives and teaching children why electronic products should not be thrown away carelessly. Communities can also organise collection drives for damaged lights and other small electronic items, helping ensure that these materials reach appropriate recycling channels.
Manufacturers and retailers have a role to play too. Designing products that are durable, repairable and easier to recycle, alongside providing clear disposal instructions and accessible take-back facilities, can make responsible choices easier for consumers.
Diwali is a celebration of light, hope and new beginnings. Its beauty should not end with overflowing dustbins and discarded electronics. Every diya we light, every decoration we reuse and every responsible disposal decision can become part of a more thoughtful way of celebrating.
Perhaps the real meaning of a brighter Diwali lies beyond how beautifully our homes shine for a few nights. It lies in the choices we make long after the celebrations are over.
Because the most meaningful light is not simply the one we switch on during Diwali, but the awareness we carry into the days that follow.
