Recycling Candle Glass: What's The Verdict?

Candles are a popular product, with Americans spending over $3 billion on them each year. However, their popularity has led to an increase in waste, with most candle containers ending up in landfills, unable to be recycled. The candle containers are usually made from glass, ceramic, or tin, with glass being the most popular. Glass candle containers are often made from borosilicate glass, which is durable and heat-resistant but not accepted at most local recycling centres. This has led to an increase in waste and environmental concerns, with many seeking alternative disposal methods, such as repurposing or donating the containers. Some manufacturers have also partnered with recycling companies to offer free recycling programs for their candle products.

Are candle glass containers recyclable?

Most candle glass containers are not recyclable

Some manufacturers are partnering with TerraCycle to create free programs for recycling their products. For example, Yankee Candle Company, Wood Wick, and Chesapeake Bay offer recycling for their candle brands through TerraCycle's free recycling program. You can drop off your used candles at a local Yankee Candle store, or print a prepaid postage label from their website to ship them to TerraCycle.

If you are unable to recycle your candle glass containers, there are other ways to dispose of them. You can repurpose the containers for a variety of uses, such as storing hair ties, Q-tips, or other small items. You can also donate them to a thrift store, or give them to a local candlemaker or artist who may want to reuse them.

It is important to note that any candle jars that still have wax residue should not be recycled. If you put a used, dirty candle in the recycling, it could contaminate the entire batch if the wax gets on other items. There are several methods to clean a used candle, such as freezing the candle and then breaking the wax apart, placing the candle in an oven, or pouring boiling water into the candle to melt the wax.

Removing wax residue is important before recycling

Glass candle containers can be recycled, but it's not as simple as recycling a water bottle. The type of glass used for candle containers is often chemically different from the glass used for food and beverage containers. Most candle containers are made of borosilicate glass, which is more durable and heat-resistant, but it is not accepted at most local recycling centres.

If you want to recycle your candle containers, it's important to first remove any wax residue. Wax residue can contaminate an entire batch of recycling if it gets on other items, a process called wishcycling, which does more harm than good.

There are several methods to remove wax from candle containers. One common method is the boiling method, which involves boiling water and then pouring it into the candle container to melt and dislodge the wax. You can also try freezing the candle overnight and then breaking the wax to remove it. Another method is to place the candle in the oven at 160 degrees Celsius for 10 to 15 minutes to melt the wax.

Once the wax is removed, you can recycle the glass container. Some candle companies, like Yankee Candle Company, Wood Wick, and Chesapeake Bay, offer recycling programs through partnerships with companies like TerraCycle. You can also check with your local thrift store to see if they accept donations of empty candle containers. Alternatively, you can repurpose your candle containers for storage or decorative purposes.

Borosilicate glass is not accepted at local recycling centres

Most candles are made of borosilicate glass, which is durable and heat-resistant, making it ideal for candles. However, borosilicate glass is not accepted at local recycling centres. This is due to its high melting point, which is greater than that of soda-lime glass. As a result, borosilicate glass cannot be effectively melted down and recycled using the standard temperatures employed at local recycling facilities, which are typically calibrated for soda-lime glass.

Borosilicate glass can be recycled, but it requires specialised facilities with higher temperatures to accommodate its unique properties. However, due to the small volume of borosilicate glass disposed of by consumers, there are very few recycling plants equipped to handle this process. The collection, shipping, and processing of borosilicate glass for recycling are costly and currently not viable on a large scale.

It is recommended that borosilicate glass be disposed of with household waste, although this contributes to landfill waste. Alternatively, borosilicate glass can be reused or repurposed for various DIY projects, such as succulent planters, cocktail glasses, or vases.

To recycle candle containers made of borosilicate glass, one must take them to commercial recycling plants. These plants have the necessary capabilities to process borosilicate glass effectively. However, it is important to ensure that the glass is completely clean and free of any wax residue before recycling, as contaminated materials can cause issues during the recycling process.

While borosilicate glass recycling is challenging due to its unique properties and the lack of specialised facilities, it is still possible to minimise waste and promote sustainability. Reusing, repurposing, or taking candle containers made of borosilicate glass to commercial recycling plants are viable options to reduce their environmental impact.

Soda-lime glass is recyclable, but rarely used for candles

Glass candle containers have a significant environmental impact. Most single-use candle containers are not recyclable in your local recycling facility. This is because the glass used for candle jars is chemically different from the food and beverage glass containers that a typical recycling facility handles. The glass used in most candles is borosilicate glass, which is more durable and heat-resistant, but it is not accepted at most local recycling centres.

Soda-lime glass is recyclable, but most glass candles do not use this material as it is unsafe when heated. Soda-lime glass has a green/blue tint, while borosilicate glass has a clear/yellow tint. When in doubt, assume that most candles are made with borosilicate glass. To recycle borosilicate glass, you must take it to a commercial recycling plant.

If you want to recycle your candle containers, it is important to ensure they are completely clean and free of any wax residue. If you put a used, dirty candle in the recycling, it could contaminate the entire batch if the wax gets on other items. This is called wishcycling, and it does more harm than good. There are several methods to clean a used candle, the most common being the boiling method. You can also try freezing the candle and then using a butter knife to remove the wax, or placing the candle in an oven at 160 degrees Celsius for 10 to 15 minutes.

Some manufacturers offer recycling programs for their products. For example, Yankee Candle Company, Wood Wick, and Chesapeake Bay candles can be recycled through TerraCycle's free recycling program. You can also repurpose your candle containers for storage or donate them to a thrift store.

Repurpose containers for storage or donate to thrift stores

Glass candle containers are not typically recyclable in your local recycling facility. This is because the glass used in candle jars is chemically different from the food and beverage glass containers that a typical recycling facility handles. Most candles are made of borosilicate glass, which is durable and heat-resistant, but this type of glass is not accepted at most local recycling centres.

However, if you have a collection of glass candle containers, there are many ways to repurpose them. One way is to use them for storage. You can use the containers to hold hair ties, Q-tips, makeup, or other small items that need to be contained. You could also use them as planters for succulents or other small plants, or as cocktail glasses or vases. If you're feeling creative, you could even make your own candles to place inside the containers.

If you don't want to repurpose the containers yourself, you could donate them to a thrift store or charity shop. Just make sure that you've completely removed any remaining wax from the containers before doing so.

Another option is to see if there are any local artists or candlemakers who would like to use the containers for their own creations. You could also try selling the containers at a farmer's market or a similar venue.
