INTRODUCTION Used Beverage Cartons (UBC) also called “Tetrapak”. On one hand, Tetrapak poses a serious threat to the environment as waste, on the other hand, a preferred source of economic recovery as a secondary raw material. Tetrapak is composed of 60 - 70 % cellulose fibers and 30 - 40 % polyethylene foils and aluminum (not always). All these components are valuable raw materials for further industrial use. However, there is one condition is that the components must be separated from each other perfectly. 9/19/2015

Threat: Serious threat to the environment as waste Raw material: A preferred source of economic recovery as a secondary raw material.

Stage Wise Operational Description- Pulping During periodical pulping at high consistency (being more suitable for hard pulpable materials) fibres are separated from foils. The products in this stage are a washed foil mixture containing less than 1.5% b. d. fibres and fibre stock collected in a chest before a coarse screening stage. In this step more than 80% of foils are separated. 9/19/2015
14
Stage Wise Operational Description- High Density Cleaning & Coarse Screening In the high density cleaning stage, on a high-density cleaner, stock is made free from sand and specifically heavy particles. In coarse screening, most of the remaining foils are removed. The foils are intermittently drained to a reject thickening unit. Accept is collected in a chest before a fine screening stage. 9/19/2015
15
Stage Wise Operational Description- Fine Screening Pressure screen (slotted screen) removes fine foils and non-pulped fractions. This reject is intermittently drained to a reject dewatering unit. Reject volume usually is not high, beverage cartonboards do not contain kind of impurities usually in other sorts of processed raw materials. Fine screening accept is thickened up to 35 – 40 % b.d. on a belt press with a palleting device. 9/19/2015

Recycling Used Beverage Cartons has following benefits: – Enabling the efficient use of raw materials by extending their life into new products. – Reducing greenhouse gas emissions. – Diverting valuable materials from landfill. CONCLUSION 9/19/2015
