Can You Recycle Candles and Wax?

Last reviewed by Sarah Chen on 01 April 2026

Wax itself isn't recyclable, but glass candle jars can be cleaned and recycled or reused. Melt leftover wax to make new candles at home.

Recycling candles presents a unique challenge because the main component, wax, can't typically go in your kerbside recycling bin. However, you can still give the glass containers a second life by washing them out and putting them in with your glass recycling, or using them for storage around the house.

According to the Shift Project, manufacturing a new smartphone produces 50-80kg of co2 equivalent.

Why Candles Isn't Easy to Recycle

Candles are made primarily of wax and wicks, which complicates their recyclability. The wax can be paraffin, soy, beeswax, or other types that don't break down easily in standard recycling processes. the wick is usually made from cotton or wood fibre, further complicating separation.

The primary issue lies with the wax. As it doesn't fit into most municipal recycling systems designed for paper, plastics, and glass. Wax has a different melting point and composition that makes it incompatible with these facilities' machinery and processes. For example, paraffin wax melts at around 130°C (265°F), which is too high for typical recycling equipment.

How to Recycle Candles Properly

To recycle candles properly, start by cleaning the glass jars thoroughly. Once clean, you can place them in your kerbside recycling bin for collection. In the UK and EU, many areas accept clear glass jars at kerbside collections or through local community centres that run special programmes.

For wax and wicks, consider upcycling or repurposing these materials yourself. For instance, TerraCycle offers a Zero Waste Box programme where you can send your used candles for proper recycling. These boxes are available both in the US and internationally but come at an additional cost since they aren't part of standard municipal services.

Alternatives to Throwing Candles Away

Instead of throwing away old candles, consider melting leftover wax to make new ones yourself. This process not only reduces waste but also lets you customise scents and designs. Another option is donating still-usable jars to charity shops or second-hand stores like Oxfam in the UK.

Alternatively, local candle makers might take back used containers for refilling with fresh candles, reducing material usage significantly. Some craft stores even host workshops on how to reuse old candle wax into new creations, building a community of upcycling enthusiasts.

According to the World Economic Forum, e-waste is the fastest-growing waste stream globally.

FAQ

How do I dispose of melted wax from broken candles? You can melt the wax and pour it into an old container like a tin can or cardboard box for safe disposal. Once solidified, it becomes inert material that won't leak onto carpets or furniture if accidentally dropped.

Is there a specific type of candle recycling service available in my area? Check your local council's website to see what kerbside collection options they offer for glass jars. Alternatively, TerraCycle runs Zero Waste Boxes specifically for candles and wax products, which you can order online regardless of location.

What should I do with used wicks from old candles? Since wicks are often made from natural fibres like cotton, they can be composted if you have a garden or community composting facility. Otherwise, consider using them in your fireplace for kindling before recycling the glass container separately.
