So today I ended up with little pieces at the bottom of the tray, so had to scoop them out into a tissue. I realised I wasted quite a bit of resin doing this. Though after disposing was thinking how bad is this stuff for the environment to put in the bin un-cured? The towel was pretty soaked. Should I leave the paper towels in daylight for a while before disposing next time?

I asked the same thing. The response I got was: put it in a ziplock and leave it out in the sun for a while to cure.

I’ve done it once and it seems to work OK.

Though what if you have no sun? 😃 I think I’d like to know the environmental impact. Is it really bad to bin this stuff uncured?

Hi @Edward\_Peretti and @David_Clark,

This is a great question, and one I often consider when working with my own printer. Disposing of cured resin is straightforward, but liquid resin is a bit trickier. As a chemical solution, it should be treated more carefully. Personally, I recommend that you cure liquid resin under light before disposing, but if you want to dispose of liquid resin, you should check with your local municipality.

Here’s a bit more information about [caring for and disposing of resin](http://formlabs.com/en/support/help/care/resin-care/).  
You might also want to take a look at our [Material Safety Data Sheets](http://formlabs.com/en/products/materials/standard/#data-sheets).

This should be helpful. Thanks again for bringing this question to the table. Other users might also have suggestions about their own disposal practices, as well.
