A 1500+ employees company is trying to be greener and instead of throwing cardboard packaging out it sends it for recycling. Recycling company won't accept less than several dozen kilograms of materials and also driving small portions of this waste very often is not economical. So the waste has to be stored for a while.
The problem is corrugated cardboard (the most typical in packaging) occupies a lot of space even after the original boxes have been "disassembled" and became just pieces of cardboard. I imagine there're some industrial machines which can tear the cardboard into pieces and maybe even compress it into pellets but those would likely be uneconomical with this scale.
Is there any easy way to preprocess cardboard that comes from packaging so it can be stored in a more compact way before it is recycled?
