Clearly, shrink wrap was also waterproof, so it's a cheap way of protecting your goods whilst in transit delivery. And we used a lot of it. In an average peak day we'll send out 500+ pallets at one distribution site in Frating alone, which is one of the two distribution sites we have. Every single one of those 500 pallets was shrink wrapped in plastic. Additional to that, within the carton itself to hold the books down, we had this plastic that shrink wrapped everything so the books wouldn't move and were protected from dust, movement and damage in transit, plus plastic bubbles to fill any gaps. A very simple way of doing it, and that's the problem – plastic is a very, very simple solution in distribution.
So, we had a massive sustainability challenge internally. In 2017 we started discussing what we could do to really try and reduce the amount of single-use plastic.
