The tidiest and most waste-free environment I ever saw was at the Carreras Rothmans cigarette factory in Basildon. (When I was a rep' of theirs).
Duty was charged on tobacco as it came out of the attached govt.bonded warehouse for processing.
Any waste tobacco that went back into the warehouse (even 'dust'), the duty was refunded.
At that time on 30p worth of tobaco leaf there was £5 duty.
Nuff said.
