The main objective of this thesis is an analysis of the recycling of liquid paperboard and the process of pulper rejects. Recycling is the process that converts waste materials into new materials and objects and recovers energy. And recycling becomes a key component of the modern world. However, with the third component of the "Reduce, Reuse, and Recycle" waste hierarchy (www.wtert.net, n.d.). Recyclable materials contain glass, paper, cardboard, metal, plastic, tires, textiles, batteries, electronics, etc.
Liquid paperboard has multilayer polymer-coated layers of aluminum foil. LPB (liquid paperboard) beverage cartons are multilayer polymer-coated paperboards that are used to make shelf-stable milk and juice products. Those cartons have an LDPE (low-density polyethylene) outer layer that provides that moisture barrier protecting the printing ink layer applied to the paperboard.
The experiment was performed in the laboratories at Arcada University of Applied Sciences.
