There are several ways to dispose of old candle wax. One way is to melt the wax and separate it from the jar, then dispose of the wax in the trash. Another way is to reuse the wax by making new candles or using it for other purposes such as firestarters. Candle jars can also be recycled or reused, but it's important to ensure that any remaining wax is removed first. Some manufacturers offer recycling programs for their candle products, and it's worth checking if your local recycling facility accepts glass candle jars as they are chemically different from food and beverage glass containers.

How to remove wax from a candle jar
Candle wax is not water-soluble, so it must not be placed in the dishwasher or poured down the drain. Instead, there are several ways to remove wax from a candle jar, depending on the type of wax and the thickness of the glass.
One method is to place the candle jar in the freezer for several hours. The wax will freeze and shrink, making it easier to remove. You can then use a butter knife or a spoon to pop the wax out of the container and scrape off any residue.
Another method is to use hot water. Place the candle jar in a pot or large metal bowl on a heat-safe surface. Pour boiling water into the pot around the candle, making sure that the water does not get into the candle jar. Let the jar sit in the hot water until the wax has softened, then remove the container from the water and pop out the wax. You can also pour boiling water directly into the candle jar, filling it halfway. Let the water cool, then pour out the water and wax.
If there is still wax residue in the jar, you can try using a hairdryer or heat gun to spot treat the area. Alternatively, you can place the jar in the oven at a low temperature (around 180 to 250 degrees Fahrenheit) until the wax becomes molten, then pour it out into the trash and wipe the jar with a paper towel.
It is important to note that you should not put a candle jar in the microwave or oven unless you are sure it is safe to do so.

How to recycle candle wax
While candle wax is not recyclable, there are many ways to reuse it.
Firstly, you need to remove the wax from its container. Never put candle wax down the drain as it will cool, harden, and clog the pipes. Instead, place the jar or candle holder in the freezer. This will make the wax shrink and easily pop out. You can also melt the wax by placing the candle in a small pot, which is then placed inside a larger pot filled with water. Bring the water to a simmer. Different types of wax have different melting points, so some waxes may take longer to melt. Once the wax has melted, remove the old wicks with tongs and dispose of them.
Now that you have removed the wax, you can reuse it in several ways. You can make your own candles by pouring the melted wax into small moulds of your choice. You can also add a few drops of essential oil and place pressed flowers in the wax. Alternatively, you can use the wax in a candle warmer to release a fragrance. You can also make gift-worthy floral wax sachets.
If you do not want to reuse the wax yourself, you can donate it to someone who might want to use it for candle-making or sell it to someone who can make fire starters with it.
Finally, while the wax itself cannot be recycled, the tins and jars that candles come in often are. Simply remove the wick and any remaining wax, and place the container in the recycling bin.

Reusing candle wax to make new candles
Candle wax can be reused in several ways, including making new candles, wax melts, and fire starters. Here is a step-by-step guide to making new candles from old candle wax:
Step 1: Prepare the old candle wax
Firstly, you need to remove the wax from your old candle jars. This can be done by melting the wax. Place the old candle jar in a small pot, then place the small pot inside a larger pot filled with water. Bring the water to a simmer, and the wax will melt. Alternatively, you can use the freeze-and-scrape method, where you freeze the candle jar and then scrape out the wax. Before melting, you can also rub liquid paraffin on the wax to help release it from the jar.
Step 2: Choose the right wax
When making new candles, it is important to use the same type of wax. Combining different types of wax may result in an uneven burn or an unpleasant aroma. Therefore, it is best to gather old candles made from the same type of wax or with complementary scents.
Step 3: Prepare the new candle container
You can use various containers for your new candle, such as a jar, tin, teacup, or votive glass. Wash and dry the container thoroughly before use. Place a new wick inside the container, ensuring it is centred. You can use a skewer, chopstick, or similar item to wrap the extra length of the wick around and keep it centred.
Step 4: Melt the old candle wax
Place the wax in a saucepan and melt it over low heat, or use a double boiler. You can also melt the wax in a microwave-safe container if you have wax in a microwavable tub.
Step 5: Add scent (optional)
If desired, you can add essential oils or fragrances to your melted wax. Citronella essential oil, for example, can help keep bugs away during summer nights.
Step 6: Pour the wax into the new container
Carefully pour the melted wax into your prepared container, stopping about half an inch below the rim. Let it stand until it sets, which may take about an hour.
Step 7: Adjust and let it set
Once the wax has partially set, you can adjust the well at the centre by pouring more wax into it until it is a quarter inch below the rim. Then, let the wax set completely.
And there you have it! Your new candle is ready to be enjoyed. Remember to exercise caution when handling hot wax and always ensure proper ventilation during the process.

Repurposing candle jars
Old candle jars can be reused in a variety of ways. Here are some ideas for repurposing your candle jars:
Storage
Candle jars can be used for storage, such as for bathroom items like Q-tips, cotton balls, hair ties, and makeup. You can also use them to store food items like dry beans, grains, snacks, and candy. If you're feeling crafty, you can decorate the jars by painting them or transferring photos onto the glass.
Planters
Turn your old candle jars into mini plant pots for succulents, cacti, or herbs. You can also use them to regrow food scraps like green onions, celery, leafy vegetables, or bean sprouts by placing the scraps in water and giving them sunlight.
Food Fermentation
If your candle jars are food-safe, you can use them for food fermentation. They are great for making kimchis, sauerkraut, or fire cider. Just make sure to leave extra space at the top of the jar for the food to expand if you plan on freezing it.
Homemade Gifts
Fill your cleaned candle jars with zero-waste items like cloth pads, face pads, or travel-size toiletries and give them as gifts to your friends.
Refills
Instead of throwing away your old candle jar, look for local shops that offer candle refills. You can choose your favourite scent and simply pop the new candle inside your old jar.
Remember, when repurposing candle jars, it's important to ensure that the jar is clean and free of any leftover wax. You can remove wax by freezing the jar and then breaking up the wax with a knife, or by pouring boiling water into the jar and letting the wax float to the top.

Donating old candle containers
If you're looking to donate your old candle containers, there are a few things to keep in mind and several options to consider. Firstly, ensure that the containers are made from materials that can be recycled or reused. Most candle containers are made of glass, metal, or plastic, which can be recycled or repurposed.
Before donating, it's important to clean the containers thoroughly to remove any remnants of wax and wick debris. This can be done by freezing the container to allow the wax to shrink and pop out easily, or by placing the container in a bowl of hot water to melt the wax, which can then be safely discarded.
Once the containers are clean, you can consider donating them to organisations such as CandleXChange, which collects brand-new or clean containers and donates them to survivors of domestic violence and refugees. They collect glass and ceramic containers and give them a second life by cleaning, refilling, and transforming them into gifts.
Alternatively, you can donate your containers to local charities or community initiatives that may find them useful for various purposes. Some organisations, like Spread The Light Candles, accept donations of leftover wax and use them for educational artistic activities and charitable giving. They also partner with other organisations to raise funds for various causes.
By donating your old candle containers, you're not only helping to reduce waste and promote sustainability, but you're also contributing to initiatives that support those in need and work towards a greener future.
