How to safely dispose of resin

Can I throw resin into the trash?

If you are anything like me, I generally start out the new year with a promise of getting more organized.  My resin studio is no exception!  I try to take an inventory of what I have and determine what I need or want.  Part of my inventory process is also disposing of products I don’t need any more.  If you are thinking about the same thing, please read these tips to make sure you are safely and properly disposing of your resin supplies.

1.  NEVER pour chemicals down your drain or toilet.  You may cause damage to your pipes or stop up your system.

2.  If you have liquid resin components that you don’t want any longer, the safest option is to take your local waste collection center as ‘hazardous materials’ waste.  These centers (at least in the U.S.) generally also collect paint, batteries, electronics, etc. to keep them out of landfills.  You can also review the safety data sheet (SDS) information for your products.  There will be recommendations and cautions on how the product can be disposed of.

3.  If you have resin containers that are empty, be sure they are capped tight before throwing the containers in the trash.  Once I have used all the contents on resin and hardener kits, I will finish with putting one cap on the other bottle.  This will cure them shut!  Alternatively, if you have a small amount of resin and hardener in each, you can pour one bottle into the other, allow to cure, then throw away with your regular trash.

4.  Cured resin is considered inert and can be disposed of in regular trash.  (Yes, you can throw your resin mistakes away.)

5.  If you are working with mixed resin and find you don’t need all of it, allow it to cure before throwing it into the trash.

If you ever have questions about how to dispose of your resin products, please contact the manufacturer.

Are you able to recycle finished resin products? I have a few mistake pieces, but I wold hate throwing them away. I like to recycle as much as possible, but I cant find any information on it.

Yes! You can incorporate them into new resin projects. Unfortunately, there is no way to remelt the resin to reuse it.

Allow the resin on them to fully cure. Once that has happened, you can throw them away in your trash.


I am wondering if there is a known recycle code for resins in general (or a product specific one…) as in, is it a #7 which means that recycling centres in Australia cannot recycle it in their usual way and won’t accept it…? Thanks 🙂

Are you talking about the containers or the resin itself? Even if I get the containers empty, I don’t try to recycle them.
