Foam densification is a fancy term for compacting polystyrene foam into tiny little blocks. Foam by definition is full of air, so smushing it anyway you can saves a lot of space, which reduces waste disposal pick ups and thus, costs.

For example, Dart Container Corp makes a densifier that can compact a foam mound the size of a Prius into the volume of a five-gallon bucket.

Foam densifiers are great fits for distribution center recycling and food service foam is very common too. The equipment isn’t cheap, so sourcing it requires great care. Leasing is a good option, especially if you are selling the densified foam to an organization who uses it as a raw material.
