Zero waste in churches: how to eliminate waste from votive candles

The invisible problem: candle waste in our churches

Every year, millions of votive candles are lit in churches across Switzerland and Europe. This act of devotion, deeply rooted in Christian tradition, hides an unsightly reality: massive waste production that ends up in sacristy bins, week after week.

For a medium-sized parish receiving 200 to 500 visitors per week, the volume of waste from votive candles is considerable. Plastic cups, melted wax residue, charred wicks, refill packaging — it all accumulates without anyone really paying attention.

Anatomy of waste from a traditional candle holder

Plastic cups: a silent scourge

Most modern votive candle systems use transparent plastic cups containing a dose of wax and a wick. These cups, often made of polycarbonate or PVC, are neither recycled nor recyclable through most municipal waste streams. They are contaminated by melted wax, making them unsuitable for selective sorting.

A church using 50 candles per day produces approximately 18,000 plastic cups per year. Multiply this by the thousands of parishes in Switzerland, France and across Europe, and the figure becomes staggering.

Wax: a petroleum residue

The majority of cheap votive candles use paraffin, a petroleum derivative. When the candle burns down, some wax remains at the bottom of the cup as solid residue. This residue:

• Is not compostable (it is a hydrocarbon)
• Contaminates other waste if disposed of with household rubbish
• Requires tedious cleaning of candle holders, often with chemical products
• Can damage stone or wood surfaces if it spills outside the holder

Wicks, metal supports and packaging

Each candle contains a wick with a metal support (often zinc or tin). These small metal elements end up in household waste. Added to this are the cardboard boxes, plastic wrapping from refill pallets and bags used for transport.

The impact on heritage

Beyond the visible waste, traditional candles cause invisible but costly damage. The soot produced by paraffin combustion settles on walls, vaults, stained glass and artworks. Organs, whose pipes are extremely sensitive to fine particles, suffer particularly from this indoor pollution.

Cleaning these surfaces represents a considerable cost for parishes, not to mention the periodic restorations made necessary by decades of accumulated soot. This amounts to thousands of francs spent each year repairing damage that could simply be avoided.

The LED solution: zero waste, zero compromise

LumignonLED LED candle holders radically eliminate the waste problem. The principle is simple: 40 LED candles integrated into an elegant holder, activated by a push button. Each press lights a candle for 5 hours, then it switches off automatically.

What disappears with LED?

• Zero plastic cups — LED candles are permanent and built-in
• Zero wax residue — no paraffin, no cleaning
• Zero used wicks — no combustion, no waste
• Zero soot — the church's air remains pure, walls and artworks are preserved
• Zero refill packaging — no more ordering and storing candles

Exceptional lifespan

Each LED candle in the LumignonLED system has a lifespan of 50,000 hours. At 5 hours per activation and several activations per day, this translates to years of operation without replacement. Compare this with a traditional votive candle that lasts 4 to 8 hours before becoming waste.

The concrete zero waste calculation

Let us take the example of a parish using 40 candles per day, 365 days a year:

• With traditional candles: 14,600 plastic cups, approximately 300 kg of residual wax, 14,600 metal wicks, plus packaging — roughly 500 kg of waste per year
• With a LumignonLED LED candle holder: 0 kg of waste. The candle holder runs on 230V mains power with negligible electricity consumption

Over 10 years, that is 5 tonnes of waste avoided for a single church. Scaled to a diocese or a canton, the impact is considerable.

An ecological choice consistent with Christian values

Pope Francis's encyclical Laudato Si' explicitly calls for the safeguarding of our common home. Reducing waste in places of worship is not just a practical choice — it is an act consistent with the ecological message carried by the Church itself.

More and more parishes in Switzerland and Europe are making this choice. They discover that switching to LED takes nothing away from the spiritual dimension of the gesture — on the contrary, it modernises it without distorting it.

Where to begin?

The transition to zero waste for votive candles is simpler than one might think. The 40-candle LumignonLED LED candle holder plugs into a standard 230V socket and requires no special infrastructure. Installation is quick and the system is immediately operational.
