Is candle wax biodegradable?

This blog post will answer the question, “Is candle wax biodegradable” and cover topics like the biodegradability of candle wax and frequently asked questions related to the topic.

Is candle wax biodegradable?

Yes, candle wax is biodegradable. Beeswax and almost all other waxes derived from plants and biological materials are considered biodegradable. It is fair to infer that candle wax is biodegradable since almost all varieties of candle wax are composed of these substances.

Is Candle Wax Composable?

The answer is yes, but only if the candle wax is comprised of organic, biodegradable materials like bee or soy wax. Paraffin wax and other petroleum-based waxes should not be used in compost bins since they are inorganic and will not decompose.

Before trying to get rid of a candle, it’s crucial to know what it’s composed of since this may help you decide how to do so safely. 

Since microorganisms can only break down organic components, only candles made of organic waxes should be placed in your compost bin.

How Should Candle Wax Be Disposed Of?

Here’s how candle wax can be disposed of:

  • Compost
  • Reuse
  • Discard

I will now elaborate on these.


The most straightforward approach to using the leftovers of a candle after it has burned out is to compost your organic candle wax.

Composting, in essence, is a microbial process that converts organic plant matter into useful soil. This is a fantastic fertilizer additive for your garden, supplying important minerals and nutrients for robust plant development.

Your candle is safe to place in your compost bin and will continue to be useful to you if it is composed of organic ingredients like bee wax, soy, palm, or coconut.


Candle enthusiasts will be aware of how simple it is to start a collection of little wax fragments. When combined, all of these little pieces are truly useful. The extra wax may be used to create a variety of items, including but not limited to:

  • Multiple-fragrance candles
  • Candle bug repellant
  • Deodorizers
  • Potpourri
  • Flammable liquids
  • Furniture wax
  • Seals for letters

Keep any unused wax in a cabinet or drawer rather than tossing it away; before you know it, you’ll have the materials for a fantastic DIY project for the house or presents.


If you don’t want to use the remaining candle wax for any DIY or craft projects and it cannot be composted. Then just placing it in your garbage is the simplest method to get rid of your candle wax.

You may use a spoon to scrape the wax out of the jar for easy disposal. To make the wax simpler to remove, you may either melt or freeze it.

Of course, this is not ecologically friendly; thus, moving forward, choosing candles made of organic ingredients will help you reduce your carbon footprint and garbage load.

Should Candle Wax Be Discarded?

You’ll undoubtedly notice a sizable puddle of wax remaining after blowing out your candle and inhaling the lovely perfume. You may be thinking about whether you should let others know about this.

No, is the response. When the candle is relit, the wax that has collected while it burned will cool and harden, ready to ignite once again.

Your candle won’t burn as long if you pour away the pooled wax because the wick will have to burn more quickly to get to the wax.

Sometimes, candles may have a problem where the wick burns more quickly than the wax and drowns. Although this is often the result of a badly manufactured candle and the issue will recur, pouring out some wax could be helpful in this situation.

Wax pouring off is a huge mess, too! After being poured, the wax thins down and exposes more surface area to the air, which causes it to cool and dry faster and produce dried drips down the edge of the candle.

Is candle wax biodegradable?

A substance is considered biodegradable if microorganisms like bacteria can break it down into its constituent elements. Candle waxes vary in their ability to biodegrade. 

Candles made of wax from natural sources, like beeswax or soy, will typically biodegrade, but candles made of wax from artificial sources, such as paraffin, won’t. Although they will eventually disintegrate into smaller bits, this is not the same as biodegradation.

You should be aware that a substance cannot decay under normal circumstances. People often think that the item will decompose in a landfill within the biodegradation timescale given. 

Typically, this is not the case. Items are jammed into the limited area in landfills. Lack of moisture and ventilation may seriously impede the process. 

Many individuals choose biodegradable products, which stay in landfills far longer than they anticipate. Even with biodegradable things, we always suggest reusing them and keeping them out of the trash for as long as you can.

Can Melted Candle Wax Be Thrown in the Garbage?

It is never a good idea to just throw out candle wax since you never know where it may end up. Greater issues may result from the wax blocking a drain or pipe if it somehow manages to get there.

However, you CAN dispose of candle wax in trash cans. The same should not be done with compost heaps, however. Candle wax may be recycled in a variety of methods, as will be covered in the sections that follow.

As an alternative, you might utilize the used or burned wax to produce a brand-new candle. In any case, always keep in mind that candle wax is reusable rather than recycled. As a result, you may discard them in your house or nearby trash cans.

Can a Candle Be Melted in a Microwave?

Yes! So long as you adhere to the proper instructions, you may melt candle wax in the microwave. Here are a few actions to get you going:

  • First, pour the wax into a dish that can be heated in a microwave. Ceramic goods are still usable, but check for the label that says “microwave safe.”
  • Heat a small container of water in the microwave for one minute, checking the temperature every 30 seconds until it reaches no more than 80°C.
  • Transfer the wax to the water-filled container and keep heating it every two minutes. Continue doing this until all the wax has melted.
  • Lastly, remove the wax from the microwave when it reaches the correct temperature and store it in a closed container with uniform distribution.
  • After letting the wax cool for a time and reaching 70 degrees, add your chosen color and aroma gradually.
  • Give the wax a slight swirl to make sure the colors and smells are evenly distributed.
  • A candle may now be created from the wax. Place it in your candle frame when it has cooled.

What is the biodegradation time of candle wax?

The time it takes for the wax to biodegrade also depends on the kind of wax in issue, just as the biodegradability of wax changes with time. Wax paper, for example, may degrade in less than 60 days depending on the kind.

Sadly, this is not the case with wax produced by refining crude oil (like paraffin wax). These waxes are not regarded as biodegradable since they may take decades to break down.

It’s interesting to note that wax paper dissolves relatively quickly, even though paraffin wax is the main component. Because the paper is so thin, this often occurs. 

Candles, which are often bigger and in pieces, cannot be claimed to be the same, hence it takes them a lot longer to entirely dissolve.

Typically, there is no set timeframe for when your wax will melt. The kind of wax and the amount used in the inquiry determine this completely. It will take much longer for the wax to break down if it is non-organic and greater in amount.

Does Wax Decompose in Water?

There is a misconception that wax dissolves in water, however, that is not accurate. Why? Wax is not water-soluble since it is made up of several lipids.

Lipids are often hydrophobic, which means they are not typically attracted to water. Because of this, water may function as a catalyst for the breakdown of wax, but water by itself is insufficient to complete the process.

Wax’s melting point must be taken into account while evaluating and figuring out how biodegradable it is. Although wax doesn’t have a set or distinct melting point, most wax melts at or around 70 degrees Celsius.

Candle wax: Is it harmful to the environment?

If created from organic and environmentally acceptable components, candle wax is never harmful to the environment. The two most common alternatives are beeswax and soy wax. These waxes are not only sustainably produced, but also very well-liked for it.

One of the greatest possibilities for manufacturing candles is soy wax, which is mostly made from soybean oil. It is completely eco-friendly and very reasonably priced. The finest thing is that it is produced using only renewable resources.

Similar to that, beeswax made from honeycombs is regarded as being environmentally beneficial. It is risk-free, non-toxic, and devoid of chemicals. 

The hallmark of this wax, however, is its ability to emit a large number of negative ions that aid in the fight against pollution.

Here, paraffin wax and other similar petroleum-based waxes should be avoided. They are not ecologically friendly and take a long time to degrade.

Frequently Asked Questions(FAQs), “Is candle wax biodegradable?”

How long does candle wax take to degrade?

Particularly wax paper, the wax may biodegrade in as little as two months or less. 

However, wax produced from the refining of crude oil (such as paraffin & microcrystalline wax) might take years to decompose, which is one of the reasons it isn’t regarded as biodegradable.

Candles biodegrade or not?

Candles made of wax from natural sources, like beeswax or soy, will typically biodegrade, but candles made of wax from artificial sources, such as paraffin, won’t. Although they will eventually disintegrate into smaller bits, this is not the same as biodegradation.

Which candle wax is most environmentally friendly?

The most environmentally friendly waxes are coconut and beeswax. Both burn cleanly and slowly, with beeswax being known for its dazzling blaze. 

But like with everything, it’s important to make sure you’re purchasing from producers and farms who support ethical agricultural methods.

Why is wax unsustainable?

You see, the majority are created using inexpensive paraffin wax, a petroleum by-product of crude oil, and when burnt, they produce massive volumes of particle pollution, a significant contributor to air pollution. 

The idea of candle purity is destroyed when metal-based wicks, synthetic smells, and boosters are used.

How are environmentally friendly candles made?

To maintain your candles eco-friendly, avoid paraffin wax. To ensure that paraffin has not been added to the wax mix, look for labels that state the product is made entirely of beeswax, soy wax, or coconut wax. 

A lead-free wick, clips, and a heat-resistant container for your candle are additional requirements.

What candle burns the cleanest?

Beeswax. The healthiest option in candles is beeswax. Beeswax candles, which are made from honeycomb caps, burn cleanly, have a very long burn time, and emit a nice natural scent as they burn. 

When burnt correctly, beeswax candles don’t leak and emit negative ions that assist purify the air in a space.
