Recycling is responsible thing to do. There is just so many different things sometimes it's hard to get all the pieces in the correct bin, or be bothered with every single piece.
Some vendors have started to make these environmental friendly packaging which are easy to recycle. That is at least what their marketing says. Maybe there is some truth in their message.
Like those yogurt cans that are wrapped in carton. Good old cans were made all out of plastic. Easy to recycle to the plastic bin, just need to wash it first. Now these new ones require the separation of the carton around the plastic and disposing separately. On top of that they are sealed with a lid made out of tin foil, so that should go to yet another bin.
Maybe the carton reduces the amount of plastic needed to make the can sturdy enough, but I doubt with the plastic still being recyclable it makes that much difference. Except on the frustration and recycling percentage of those cans when people just don't feel the effort is worth it. This reduction of plastic might hence reduce the environmental friendliness of those packages after all.
