Project title: Adaptation of a power plant that produces expandable polystyrene
Investor: EPSIK d.o.o. Zagreb
Location: Žitnjak
Construction completion: 2006
Project description
The PS II plant was revitalized in order to increase the production capacity of expanded polystyrene to 16 000 t per year. The former EPSIK production unit consisted of two plants, Polystyrene I (PS I) and Polystyrene II (PS II). Polystyrene grain (PS) was produced in PS I as the first stage of expanding polystyrene (EPS) production. Most of the PS produced was sent for further processing to PS II for the second stage of EPS production. A small part was processed in the final processing stage of PS I into a finished product of general purpose polystyrene (GPS) and rubber modified polystyrene (HIPS). This plant was closed in 1998. The reopening of production is not planned.
In PS II, EPS was produced in the second stage of production. With the closure of PS I, the entire production of EPS (first and second stage) was transferred to PS II with the use of some auxiliary sections in PS I. Production was closed in 2003 due to inefficiency. The owner decided to initiate activities for the revitalization of the existing PS II plant, which will be adapted to a one-stage production of EPS by purchasing a license and replacing parts of the existing equipment. This adapted plant retains its appearance, capacity and technological flow of the existing PS II and auxiliary sections in PS I. The new EPS product basically retains or improves the properties of the product manufactured until 2003, with higher utilization, lower energy consumption and reduced emissions into the atmosphere.
