Thank you all for your input.

Let me get this straight... I have noted the following:

1) Black bin bags are for putting rubbish in them which CAN be recycled.

2) The Zurisacks are for putting rubish in them which CANNOT be recycle.

Is this correct?

3) If you just use the black bin bags and not the Zurisacks, do not throw any letters or paper away with your name on.

4) Black bin bags are normally for businesses (even though they are readily available in all supermarkets). Isn't this confusing, since you do not see the Zurisacks on the supermarket shelves?

5) Provided I got (1) and (2) above correct, then the next question is, what is recycable out of your normal daily shopping waste?
