Showing an icon (front end) for selected checkbox (back end)

Hi,

I run my online shop with Woocommerce. I have created several checkboxes on the product level (specific custom post type).
Bio, Upcycling, Swiss Made, Handmade, Fair & Social

If I enter a new product or if I modify an existing product I can maintain this checkboxes.

Now I'd like to display for each selected checkbox a specific Icon on the single product page, in the area of product description (front end).
Even I have a licence for "View" I think this could be done with some code directly in the template.

Can you give me an example how the code has to look like?

Thanks a lot!
Serge
