Can You Recycle A Candle Jar?
Standing by the bin holding an empty candle vessel, we've all internally debated at some point, “Can candles go in recycling?" It just makes sense, right?
Well...(even though it's always annoying to have an 'it depends' type of response) the answer is more complicated than ideal, BUT you are actually asking the more mindful question!
Hopefully learning a little bit about the why's and how's of sustainability will add clarity on what to do with used candle jars, so that they don’t end up in landfill waste due to wishful recycling, or 'wishcycling'.
Here's what I've learnt running a candle recycling program out of Brooklyn (we recently crossed the '100 jars sent in' milestone!), and what I think every conscious candle buyer deserves to know.
WHY MOST CANDLE JARS AREN'T CURBSIDE RECYCLABLE
...even when they look like they should be.
Glass and metal are currently the most recyclable materials we have. So when you're holding a thick glass candle vessel or a clean candle tin, the instinct to recycle it makes total sense.
The problem is wax. Any wax - including well-regarded 'eco' ones like soy or beeswax - is not recyclable. And because residual wax clings to the inside of almost every used candle container, unless it's properly cleaned specifically for this purpose, it immediately contaminates the recycling stream.
Most municipal programs sort at scale, not by hand, so any jar with leftover wax gets flagged and pulled – and it ends up in landfill, even though the glass or metal itself are theoretically recyclable forever (literally called 'infinitely recyclable').
So unfortunately, that jar you've been rinsing out and thoughtfully putting in the blue bin?
There's a real chance it's been going straight to landfill for years. Not because you did anything wrong, but because nobody talks about the complexities of the process– and the wax.
"A jar is only as recyclable as what's inside it. And wax (even natural wax) disqualifies most vessels the moment the candle is burned."
HOW TO CLEAN A CANDLE JAR TO ACTUALLY REUSE IT
And if you ain't got the time or space for reusing candle jars (I feel your pain!) just skip to the recycling section below.
Before we get into recycling: reuse is always better. Keeping a vessel in circulation skips the recycling process entirely and gives a well-made object a second life. The main obstacle here is getting the wax out. A few tried and true methods that genuinely work:
The Freezer Method (easiest for small amounts of wax)
Put the jar in the freezer for 1-3 hours, depending on the amount of wax. As wax cools it contracts, and in many cases it'll pop out as a single disk you can lift right out. Wipe clean with a paper towel, then wash with dish soap. Works particularly well on wider or straight-sided glass jars.
Hot water pour
Boil water and once it has cooled for a few minutes, pour it carefully into the candle jar. The heat melts the residual wax, which floats to the surface as the water cools. Once it coagulates at the top, scoop it out and dispose of it in the bin (not down the drain– it'll solidify in your pipes!) You'll likely need one more wash after.
This method skips the tedious digging out of the wax (like in the freezer method) and is the most effective. Although, it can leave a thin film and get a touch messy sometimes, so use gloves and set aside enough time.
Double boiler or low oven
For heavier wax deposits or awkwardly shaped vessels, placing the jar in a shallow water bath on the stove or in a low oven (around 170°F, on a foil-lined tray) will melt everything out cleanly. Slightly more involved, but this is by far the most thorough method on this list.
IDEAS FOR WHAT TO DO WITH EMPTY JARS
(In case you still have shelf space left, that is)
Once cleaned, candle jars can be genuinely useful:
- Bathroom storage for cotton pads or cosmetics
- Bud vases, small planters for succulents, herbs, or plant propagation
- Pen or trinket holders
- Junk drawer organisers
- Additional bev cups for parties (clean 'em extra well for this pls!)
A sturdy, well-made jar - especially if it's glass - has a long second life.
That said, this works until it doesn't.
"There shouldn't be so much eco-judgement around falling behind on sustainable choices once they start to feel unrealistic."
Most people can happily repurpose a jar, or three. By the sixth, you're accumulating containers faster than you're finding uses for them. The intentions are good, but the jars start piling up, and eventually they end up in the bin anyway, just later (and possibly having already taken up your time and effort with cleaning).
I think it's worth being honest about that. There shouldn't be so much 'eco judgement' around falling behind on sustainable choices once they start to feel unrealistic.
That's actually how I stumbled onto our candle recycling idea at The Parallax Company.
I saw my candle shelf and was trying to find a solution that was beyond just the "tips for repurposing your jars".
I wanted an actual system for what happens when someone has burned through tens of candles, wants to dispose of them correctly, but doesn't know what to do, and has no time or space to find the answer.
So we built it.
A no-cost candle recycling program that lets our customers send back used vessels (from any brand, not just ours). Because cleaning containers for proper recycling or reuse, is obviously a whole lot easier with the industrial-grade tools I already have on hand for the candlemaking biz.
I'm also pretty proud of the fact that there's no catch, and the whole point is just to reduce the friction so that the "right" thing can be easy, for once!
