Cardboard shredder ROI calculator
A cardboard shredder turns the waste boxes you already throw away into void fill, so you stop buying paper or bubble to protect parcels. This works out how quickly the machine pays for itself against your current void-fill spend.
Estimate only. Assumes enough waste cardboard to feed the machine and excludes running costs, which are small relative to void-fill savings.
How the maths works
Every parcel you pad with shredded cardboard is void fill you didn't buy. If you currently spend, say, £300 a month on void fill and a shredder can replace most of it, that saving pays down the machine price in months, not years, then keeps saving after that.
The bigger your outbound volume and the more waste cardboard you have on site, the faster the payback. It also cuts waste-collection volume and gives you a “we reuse our own cardboard” sustainability story.
