Business Law question (Non-Profit Sphere)

I am a current college student and a member of Enactus, and our project is in relation to environmental sustainability. Our team has the idea of creating grocery bags by upcycling T-shirts and selling them at local stores and larger chains later on. A portion of the proceeds would go toward the non-profit area of our project, aiding a local program that provides resources for at-risk children to succeed.

Ideally in order to obtain the necessary materials for our project we would hold some sort of T-shirt drive at our university or attempt to network with local donation centers, but I am still uncertain about the legalities of reselling a product that could have copyrighted logos on them? If this is not possible to do that would make our business plan much more difficult but I wanted to seek advice on this issue! Any help will be well received, thank you :)
