Candles have been a part of human society for over 5000 years, used for lighting homes, aiding travel at night, and in religious ceremonies. However, with growing concerns about sustainability and eco-friendliness, the question of whether candles are compostable or recyclable has gained prominence. While candles are made from biodegradable materials, it is challenging to recycle them due to the difficulty in breaking down the solid wax chunks. As a result, there has been a rise in popularity of soy and palm oil candles as cleaner, longer-burning alternatives to paraffin, which is derived from petroleum.
Are candles compostable?
| Characteristics | Values |
|---|---|
| Recyclability | Candles cannot be recycled, but they can be reused or repurposed. |
| Composition | Candles are typically made from paraffin, a petroleum byproduct, or soy. They can also be made from beeswax, gels, and other chemical waxes. |
| Eco-friendliness | Paraffin candles are not eco-friendly as they produce toxic chemicals when burned and are not biodegradable. Soy candles are generally considered more eco-friendly, but the soybean industry has been criticized for deforestation and the use of pesticides and fertilizers. Beeswax candles are natural, biodegradable, and renewable but may not be vegan-friendly. |
| Health concerns | Paraffin candles can release toxic chemicals such as benzene and toluene, which are known carcinogens. Artificial dyes and fragrances can also release harmful chemicals. |
| Alternatives | Eco-friendly alternatives include candles made from coconut wax, rapeseed wax, palm oil, or essential oils. Wicks should be made from natural materials like cotton, hemp, or wood. |
| Reuse and repurposing | Old candles can be melted down and reused to make new candles. Leftover candle wax can be used for lubrication or to preserve metal objects. Non-profits like St. Vincent de Paul repurpose old candles into products like fire starters and bricks of wax for crafting. |

What You'll Learn
Candle wax is mostly biodegradable
Candles are made from a variety of substances, and while some are biodegradable, others are not. Paraffin candles, for example, are made from petroleum waste and are not biodegradable. They are slightly toxic and produce large amounts of particulate matter and toxic chemicals like toluene and benzene when burned. On the other hand, candles made from natural, plant-based materials like soy, palm oil, beeswax, coconut wax, rapeseed wax, or vegetable fats are biodegradable. These candles are considered eco-friendly and are better for the environment.
Beeswax, in particular, has been used in candles for thousands of years and is known for its slow and clean burn. It is a natural, biodegradable wax that has risen in popularity as a cleaner alternative to paraffin. Soy candles have also gained popularity due to their longer burn time and natural plant-based composition. However, there are some concerns about the soybean industry's use of pesticides and fertilizers, as well as deforestation.
To ensure the sustainability of your candle choices, it is important to support companies that responsibly source their materials. For soy candles, look for companies that source their soy from traceable US soy crops or RTRSA-certified plantations. This helps to address issues such as deforestation and the impact on indigenous communities. Additionally, opt for candles with wicks made from natural, clean-burning materials like cotton, hemp, or wood, and avoid candles with artificial dyes and fragrances, as these can release harmful chemicals into the air.
While candle wax is mostly biodegradable, it is important to note that there are challenges in the recycling process. Candles with containers, such as jars or tins, can be recycled by cleaning out the wax and disposing of the container appropriately. However, for partially burned or leftover candle wax, the best option is often to repurpose or donate them to organizations that melt them down and create new products, such as EcoFire starters or bricks of wax for crafting.

Candle wicks are often non-biodegradable
When recycling or composting candles, it is important to remove the wicks. The wicks can be cut out or separated from the wax, and then the wax can be melted and reused. This process ensures that the non-biodegradable components of the candle are not included in the final product.
Some candle manufacturers have started using natural and clean-burning materials for wicks, such as cotton, hemp, or wood. These wicks are designed to be eco-friendly and non-toxic. They are made from sustainable and renewable resources, which makes them a more environmentally friendly option compared to traditional candle wicks.
It is worth noting that while natural wicks are biodegradable, they may still contain small amounts of metal. This is because the wicks are sometimes reinforced with a thin metal wire to keep them upright and prevent bending. These metal components are non-biodegradable and must be separated from the wax before composting.
Overall, candle wicks are often non-biodegradable due to the presence of metal rods or synthetic materials. When disposing of candles, it is important to separate the wick from the wax to ensure proper recycling or composting. Natural and clean-burning wicks are available as a more environmentally friendly alternative.

Reusing candles
While candles can be difficult to recycle, there are plenty of ways to reuse them.
One way to reuse candle wax is to melt it down and remove it from its vessel. To do this, you can place the candle in a small pot inside a larger pot filled with water and bring the water to a simmer. You can also place the candle jar in the oven at its lowest setting. Be sure to remove any labels or stickers first. Once the wax is melted, scoop it out and reuse it. Another method is to place the candle jar in the freezer, which will cause the wax to shrink and pop out.
Before melting the wax, it is important to prepare it by rubbing liquid paraffin on it to help release it from the jar. After melting the wax, remove old wicks with tongs and toss them out. If there is only a small amount of wax in the jar, you can simply run hot water over it to remove the wax drippings.
Once you have removed the wax, you can reuse it in a variety of ways. You can make your own candles by purchasing wicks and candle holders from a craft store. You can also add fragrances or candle dye to intensify the colour of the candles. If you are combining the remnants of several candles, make sure they are all the same type of wax. You can also use leftover candle wax to make gift-worthy floral wax sachets or wax melts for a candle warmer.
If your leftover candle is made of beeswax, you can rub it on a sticky drawer or window sash to ensure it slides smoothly. You can also use it to preserve bronze and copper objects or wax string when making jewellery.

Recycling candle jars
Although candles are made from biodegradable materials, there is no good way to recycle them. However, there are several ways to reuse candle jars. Before reusing or recycling candle jars, it is important to remove any leftover wax. One way to do this is by placing the candle jar in the freezer for a couple of hours and then using a butter knife to pop out the frozen wax. Alternatively, you can pour boiling water directly into the candle jar and wait for the wax to float to the top. Once the wax has hardened, simply remove it from the water.
After removing the wax, the jar can be recycled or reused. Some companies, such as Yankee Candle, offer recycling programs for their used fragrance products. You can also choose to reuse the jar for other purposes. For example, you can use it as a pen or pencil holder, or for storing small items in your kitchen or office. Another option is to use the jar as a planter, but remember to add drainage stones if you plan to plant directly into the jar.
If you want to get creative, you can even make your own candles using the recycled jar. To do this, you will need to purchase wicks, fragrance, and dyes from a craft store. You will also need a large saucepan to melt the wax and a mold to create the desired shape for your new candle. Once you have your supplies, simply melt the wax, add your desired fragrance and color, and pour it into the prepared mold or jar. Allow the wax to harden, and you will have a brand new candle to enjoy!
By recycling or reusing candle jars, you can not only reduce waste but also find new and creative ways to utilize these items in your home. Whether you choose to recycle, upcycle, or simply reuse these jars, you are taking small steps towards a more sustainable lifestyle.

Eco-friendly candle alternatives
Candles are made from a variety of materials, including paraffin wax, beeswax, soy wax, and coconut wax. Paraffin wax, also known as petroleum wax, is a byproduct of the petroleum industry and is not considered environmentally friendly. Burning paraffin candles can emit trace amounts of chemicals such as formaldehyde, acrolein, and naphthalene, which are harmful to both human health and the environment.
Fortunately, there are several eco-friendly alternatives to traditional candles that can provide a warm and soothing atmosphere without the negative impact on the environment or indoor air quality. Here are some sustainable options:
Soy Candles
Soy candles are made from soy wax, which is a natural and renewable resource. Soy candles are a popular choice for eco-friendly consumers because they burn longer than paraffin wax and are free of toxins. An example of a soy candle brand is Spruce Soy Candle.
Coconut Wax Candles
Coconut wax candles are another sustainable option, as coconut wax is also a natural and renewable resource. Coconut wax candles are known for their stimulating scents and long-burning times. Berryline Candles is a brand that offers coconut wax candles that are paraffin-free, paraben-free, sulfate-free, phthalate-free, and cruelty-free.
Beeswax Candles
Beeswax candles are a natural alternative to paraffin wax candles. Beeswax is a byproduct of the beekeeping industry and is biodegradable and non-toxic. Beeswax candles are known for their pleasant, honey-like scent and long-burning times.
Electric Wax Warmers
Electric wax warmers are a great alternative to scented candles as they slowly melt wax melts and release their scent into the home without the need for a lit wick. Wax melts can be made from renewable waxes and natural fragrances like essential oils, providing an eco-friendly and pollution-free option for scenting your home.
Natural Home Decorations
Bringing natural elements into your home is an excellent way to scent your space without any harmful chemicals or pollution. Decorate your home with fragrant dried spices like nutmeg, cloves, and cinnamon, or dried fruits like lime, orange, and lemon. You can also bring in pine branches or fresh flowers to create a light and fresh scent throughout your home.
