Donate or safely dispose of your old nail polish—older polishes are particularly bad for the environment due to toxic chemicals like toluene and phthalates, which leach into the groundwater. You have the option of donating your old polish, mailing your old polish to Zoya, or dropping them off at your local Household Hazardous Waste (HHW) location (EPA link, Canadian link). My city, Toronto, holds Community Environment Days at various locations, and I like to save up my electronic waste and HHW for when an event is held in my neighborhood.
Details from Zoya:
Once you receive your order, decide if you are going to send in your unwanted polishes or donate them to a local cause. We are using the honor code to make sure you get your Zoya Nail Polish as quickly as possible! Offer is not contingent on customer returning polish. If you do choose to send us your old polish, we promise to properly dispose of it according to environmental guidelines. If you choose to ship back polishes, please include a copy of your invoice with your order and make sure to comply with the shipping guidelines by your carrier of choice. You do not have to send us the exact amount of bottles that you are ordering, there is no limit! Please note: You will need to check with your carrier of choice for guidelines and restrictions on shipping nail polish.

This promotion is open to Continental US and Canadian customers only.
I’ve just placed my order (Amira, Claudine, Lacey, Logan, Millie, and Zara; I also got 3 “fun sized” bottles—Cece, Neely, and Temperance—from their Easter promo, which are 7 mL and $6 each, though the current deal is 3/$10 and the Earth Day 50% off doesn’t work on top of that; the mini bottle of Remove Plus is a freebie). I didn’t realize until just now that I got a lot of green in my order! Earth Day must have been on my mind! 🌎
