Candles are widely used for their stress-relieving and ambient qualities, but are they eco-friendly? The answer depends on the type of candle wax and wick used. Most commercial candles are made from paraffin wax, a petroleum by-product that takes around 100 years to decompose due to its chemical composition. Natural waxes like soy, coconut, and beeswax are biodegradable alternatives, taking less than two months to decompose. Candle wicks are generally biodegradable, except when containing lead or metal. Upcycling empty candle jars is another way to reduce waste and create eco-friendly solutions for your home.

What You'll Learn
Candle wax decomposition depends on its source
The decomposition of candle wax depends on its source. Most candles are made from paraffin wax, derived from petroleum, and cannot decompose due to their chemical makeup. Paraffin wax can take around 100 years to break down. Natural wax candles, on the other hand, can decompose in under 60 days as they do not contain harmful chemicals.
Beeswax, for example, is a natural alternative that can break down in around a month. Beeswax candles have been used for centuries, dating back to ancient China and the Tang Dynasty (618-907 AD). However, beeswax was historically expensive, making it a less common choice for households. Today, beeswax remains the most expensive natural candle wax option.
Soy wax and coconut wax are other natural alternatives that can decompose in about six weeks. These waxes are free from harsh chemicals and do not emit toxic chemicals when burned. Soy wax, in particular, has become a popular choice for commercial candles since it was developed in the late 1990s.
Stearin wax, which is primarily used in Europe, is derived from animal fatty acids. Vegetable-based waxes, such as palm wax, are also available, although their impact on the environment is less clear. It is important to note that while natural wax candles are biodegradable, the wicks and fragrances used in candles may still contain metal or other harmful chemicals, hindering their ability to decompose.

Paraffin wax candles don't decompose
Paraffin wax is a by-product of crude oil and is derived from petroleum, which is a non-natural source. This means that paraffin wax candles do not decompose due to their chemical makeup. Paraffin wax contains harmful chemicals that take a long time to break down, and it is estimated that paraffin wax can take around 100 years to decompose.
Paraffin wax is commonly used in candle-making because it is affordable, burns consistently, holds fragrance and colour well, and has an attractive finish. However, burning paraffin wax candles can release harmful chemicals into the air, including substances like benzene, toluene, and formaldehyde, which are linked to various health issues such as respiratory irritation, allergies, and even cancer.
Paraffin wax candles are also not environmentally friendly. As a byproduct of crude oil, a non-renewable resource, its production contributes to air pollution and environmental degradation. When burned, paraffin wax candles emit black soot, which can contribute to indoor air pollution and several health problems.
To avoid the negative health and environmental impacts of paraffin wax candles, it is recommended to choose natural wax candles made from coconut, soy, or beeswax. These types of wax are biodegradable, do not emit toxic chemicals when burned, and take much less time to decompose, typically under 60 days. Beeswax candles, in particular, are a great natural alternative as they can break down in under a month.
When choosing candles, it is also important to consider the wicks, packaging, and perfume. Wooden, cotton, or hemp wicks are biodegradable, while candle packaging should be glass, paper, or cardboard, which are reusable or recyclable. To avoid indoor pollution, opt for candles with essential oil fragrances instead of perfumes, which often contain phthalates that emit harsh chemicals.

Natural wax candles are biodegradable
Beeswax, for example, is a natural alternative for candle lovers. It is produced by honeybees and can break down, making it a sustainable option. Beeswax candles also burn longer and cleaner than many other types of candles. However, the sustainability of beeswax depends on responsible beekeeping practices to ensure environmental balance and maintain bee population health and biodiversity.
Soy wax is another popular eco-friendly option. Derived from soybeans, a renewable resource, soy wax is biodegradable and has a low toxicity, making it a preferred choice for candle makers. It burns cleanly, producing less soot and toxins than paraffin wax. Coconut wax is also a natural and sustainable option for candle-making. Coconuts are a renewable crop, making coconut wax biodegradable and environmentally friendly. It burns cleanly and efficiently, with minimal soot and emissions. Additionally, coconut wax has excellent fragrance-holding capabilities, making it ideal for scented candles.
When choosing candles, it is important to consider not only the wax but also the wick and the packaging. Most candle wicks are environmentally friendly as long as they do not contain lead or metal. Wooden, cotton, or hemp wicks are all biodegradable options. Candle packaging can often be made of plastic, which is non-recyclable. Glass candle jars are recyclable, but they can also be reused or upcycled at home.

Glass candle jars can be recycled
The next step is to melt the remaining wax. This can be done by pouring hot water into the jar, filling it around three-quarters full. As you pour, the wax will melt and slowly rise to the surface. It is important to be careful during this step, as the jar will become extremely hot. After allowing the jar to cool for around four to five hours, the wax will have solidified at the top.
Now, the wax can be removed. This may require some effort, and you can use a butter knife to help scrape down the inside of the jar. You can also use a heat gun to melt and wipe away any remaining wax. It is important to ensure that all wax is removed and that the jar is impeccably clean before recycling. One way to achieve this is by using a mixture of warm water and vinegar to scrub the inside of the jar.
Recycling glass candle jars is an important way to reduce waste and promote sustainability. Glass can take up to 4,000 years to decompose, and it is one of the most polluting substances on Earth, causing harm to countless animals. Therefore, it is crucial to recycle or repurpose glass candle jars whenever possible. Repurposing ideas include using the jars for storage, DIY crafts, planters, vases, or bathroom organizers.
