Why is card collected in sacks, wouldn it be better to provide another plastic box for card?
We have trialled the use of sacks for cardboard collection for a number of years and have found that they perform very well. The dimensions of the sack makes it more suitable to accommodate bigger pieces of cardboard yet they can save the householder space too, unlike the sack a plastic box takes up the same amount of space when it is empty or part full as it does when it is full.
