This is noble but seems a little misguided. Legos seem like they'd have by far one of the lowest carbon to utility ratios of any toy you can buy. I used the ones I had as a kid for hours almost every day. I've passed them down to my kid who uses them daily. More than 99% are in perfect shape and I see no reason we won't one day pass them onto another generation.
When you're discarding the plastic junk some family member got for your kid just last Christmas, there probably aren't any Legos in there.
In the worst case, they're high quality ABS so they're more recyclable than most packaging you bother to sort.
