Talking absolute bolox.
you could actually use just one plastic carton top for the whole of your life. Or even a Topster if you like it.
Or send probably in excess of 200 a year to landfill.
Yes I agree you are talking absolute bollox .......................again
As previously stated the screw on top is primarily there to protect the seal , read that again & make sure you understand it this time
Secondly plastic milk cartons are one of the few things we as a nation efficiently recycle, yes many do go to landfill but the vast proportion do not , check the figures
