This is the story of Ponikve eko otok Krk utility company in Croatia, which in 2020 decided to implement a complete sorting line – Ecostar’s Hexpert system – to treat the green and organic waste from the island of Krk.
Krk is the most populous island in the Adriatic Sea (around 20.000 inhabitants during the winter season) that had been having a waste management system since 2005, where waste is collected separately. In 2014, the whole system was upgraded to a door-to-door one, integrating the user responsibility scheme and the collective awareness of the locals, visitors, and tourists. Given this door-to-door system, the company was facing ever-growing quantities of biowaste (green and organic), around 5000 tons per year, collected in plastic bags, thus they needed a pre-treatment system to separate the biowaste from the plastic bags to have a clean material to then turn into quality compost.
Before the installation of the Hexpert sorting line, the separation process was difficult, time-consuming, and underperforming. Moreover, during peak seasons when the island is flooded by tourists (around 140.000), the quantities of material to be sorted increased dramatically so the waste was accumulating waiting to be processed, and beginning to ferment before the separation, thus leading to a difficult sorting process because of humidity.
The solution: Hexpert – Ecostar system for the treatment of the organic waste in Krk
In Ecostar, thanks to the Hexact modular screen and our team’s efficiency, we can develop turnkey solutions, designed according to the client’s available space and material to be screened. With Hexpert the operator can increase capacity and precision in the separation of waste and of the materials to be screened, significantly reducing investments in ancillary structures.
That was also the case of Ponikve waste management facility where in 2020 an Hexpert complete sorting line was installed to treat the green and organic waste of the island of Krk. The line comprises:

Today, the island of Krk benefits from a strong waste management system, where household green and organic waste is being treated and separated from other materials and sent to the aerobic digestion process. This small community, thanks to its locals and municipality is today an example of “yes, we can” to the rest of the country, waiting for its tourists this summer as it is fully ready and equipped to successfully handle the entire waste of the island.
