The following was the response I received from MAC last week...I think I asked them the question about a month ago....Also My MAC Pro told me they were no longer be accepting depots moving forward. I asked her if that meant no depots or complete packaging...she said complete packaging only..as long as I turn in all the pieces including a pan that they would take it.

Dear Valued Consumer,
Thank you for taking the time to contact us and for your interest in M.A.C. We apologize for the delay in our response.
Because we share your concern about our environment, with the Brand's inception in 1985 we established the "Back to M.A.C." program: When you have finished using M.A.C. plastic packaged cosmetic items purchased from us, please bring the containers back to a M.A.C. location near you. Although we cannot reuse these containers for our products, we can make sure the packaging materials are properly recycled. To credit you for your good deed, the accumulation of six (6) recyclable plastic containers entitles you to select one free M.A.C. lipstick as our thanks. Please note: Since 100% of the retail selling price of Viva Glam Lipsticks is provided to organizations that help people living with HIV/AIDS, Lipsticks in this series are excluded from this program. With regard to your inquiry, there are no plans to discontinue the Back To M.A.C program; however, the program is not available where regulations prohibit.
We trust the above addresses your concern. We hope that we have the opportunity to serve you in the near future.
Sincerely,
Marla Katz
