Throwing out candles can be tricky, especially if you want to dispose of them sustainably. While traditional candles made of paraffin can be thrown in the garbage, it's better to reuse or recycle them. To recycle a candle, you must first separate the wax from the container. This can be done by freezing the candle and using a knife to pop out the frozen wax, or by pouring boiling water into the jar and letting the wax float to the top. Once the wax is removed, the container can be recycled with other glass products. The leftover wax can be reused in various ways, such as by making new candles or adding it to a compost pile.

Removing wax from the container
Removing wax from a candle container is a necessary step before recycling or reusing the jar. It is important to note that wax is not water-soluble, so jars with leftover wax must not be placed in the dishwasher. Instead, there are several methods you can use to remove the wax:
Freezing the Wax
Place the candle in the freezer for a couple of hours, or until the wax is frozen. Before freezing, try using a butter knife to make cuts in the wax, as this will make it easier to break up and remove the wax once it is frozen.
Boiling Water
Pour boiling water directly into the candle jar, leaving some room at the top. The wax should dislodge and float to the top. You can then use a paper tissue or kitchen roll to absorb the wax while it is still warm, or wait for it to cool and simply pop it out.
Oven
Place the candle on a baking sheet and put it in the oven at around 160 degrees Celsius for 10 to 15 minutes. The wax will melt and can then be poured out.
Microwave
Place the candle in the microwave for a couple of minutes to help melt the wax. Be careful when handling heated wax and hot water, as there is a risk of burning yourself.
Once the wax has been removed, it can be reused or disposed of in the general waste bin. The jar can then be recycled or reused for various purposes.

Disposing of wax
To dispose of candle wax, you must first separate the wax from the candle container. This can be done by melting the wax. One way to do this is to place the candle in the freezer for a couple of hours, or until the wax is frozen, and then use a butter knife to pop the frozen wax out of the container. Alternatively, you can place the candle on a heat-safe surface and pour boiling water directly into the candle jar, leaving some room at the top. The wax will float to the top, and you can simply pick it out once the water has cooled and the wax has hardened.
Once you have separated the wax, you can dispose of it in a few different ways. Small amounts of solid candle wax can be thrown into your general waste bin, as long as it is cool and dry. You can also repurpose the wax by melting it down and using it to make a new candle. If you have a compost pile, you can add the wax to it, as the natural ingredients will break down over time, enriching your compost with organic material. Alternatively, you can bury the wax in your garden, where it will decompose naturally.
If you are disposing of a glass candle jar, it is important to note that these are 100% recyclable. However, you must remove any wax and wash out the jars before recycling them. This removes contaminants and increases the chances of recycling. You can take your clean glass candle jars to your local bottle bank or household waste recycling centre (HWRC) to recycle them with other glass waste.

If you are feeling creative, you can even decorate the jar to give it a new look.
If you are unable to reuse the container yourself, you can donate it to a thrift store or recycle it. Glass candle jars are 100% recyclable and can be taken to a local bottle bank or household waste recycling centre (HWRC). However, it is important to ensure that all wax and residue have been removed before recycling, as this can contaminate the process.
Overall, reusing candle containers is a simple and effective way to reduce waste and give new life to decorative jars. With a few simple steps, you can easily clean and repurpose your candle containers for a variety of household uses.

Composting candle wax
When it comes to composting candle wax, the type of wax is the most important factor to consider. While some waxes, such as soy wax and beeswax, are compostable, others like paraffin wax, a petroleum-based product, are not biodegradable and can contaminate the soil. Therefore, it is crucial to determine the type of wax before composting.
Soy wax and beeswax are natural waxes that can be composted. However, they take a significant amount of time, ranging from several months to a year or more, to fully decompose. The decomposition time depends on factors such as the size of the wax pieces, the temperature of the compost, and the presence of microorganisms. Breaking down the wax into smaller pieces can expedite the process, and a compost shredder can be useful for this purpose.
Beeswax, in particular, is a natural and eco-friendly alternative to paraffin wax. It is biodegradable and can be added to your compost pile. However, due to its slow decomposition, it is advisable to break it into smaller pieces before composting. This will facilitate the breakdown process and ensure that microorganisms can effectively decompose it.
Although composting is a viable option for certain types of candle wax, it is important to avoid composting scented candle wax. Fragrances and dyes used in scented candles may contain chemicals that can be harmful to your compost pile and the environment. Therefore, it is recommended to opt for alternative methods, such as reusing or repurposing the wax, when dealing with scented candles.
If you are unable to compost your candle wax, there are several creative ways to reuse it. You can melt down the leftover wax using a double boiler and create new candles by pouring it into containers with wicks. This reduces waste and allows you to customize your candles. Additionally, candle wax can be utilized as a natural lubricant for sticky drawers and zippers, or as a waterproofing agent. It can also be combined with dried leaves, pinecones, or other flammable materials to create fire starters for camping or backyard bonfires. These alternatives not only give your candle wax a second life but also contribute to a more sustainable lifestyle.
