The New End-of-Waste Treatment Cycle in Roster LTD

Roster Ltd has been operating throughout Europe in the field of demolition for over thirty years. Additionally, the company deals with the recycling of scrap resulting from their demolition work. Keeping this in mind, Rosen Terziev, owner and founder of the Bulgarian company, decided to close the recovery cycle internally, making the most of the metals and choosing Panizzolo technologies for an End-of-Waste treatment.

Roster Ltd: an ambitious and structured industrial reality
Roster Ltd was founded in 1990 and specialized in the mechanical demolition of buildings, disassembly of plants, equipment, industrial machinery as well as ferrous metal processing and recycling. Nowadays, the company focuses on the demolition of public and private structures, both industrial and structural. “In this sector, the choice of the machinery with which to operate is fundamental. For this reason, we choose from the products of world-class manufacturers with proven effectiveness and productivity. High-performance machinery and good technical availability allow us to work quickly and efficiently,” explains Rosen Terziev, representative and director of the company. The company operates throughout Europe with import and export channels for recycled materials to the Netherlands, Hungary, Romania and Turkey. “Therefore, we are constantly looking for new partners and new markets,” Terziev underlines.

The company has a young and ambitious staff, with technicians and operators focused on the company’s growth. “I have a highly professional team, who, in carrying out their business, assure customers honesty, cooperation and personal dedication. Currently, more than 200 people work in the company, operating in the dismantling and recycling departments divided into three offices within the national territory,“ explains Rosen Terziev. Roster Ltd is, in fact, present in Smolyan with the administration and an operational area of eight thousand square meters in Plovdiv. Moreover, they own the second branch of three thousand square meters, while in Kameno they operate within the third site of 37 thousand square meters. “Not to mention the various construction sites throughout Europe, with a staff of engineers committed to following every single phase. Our offices act as a logistics center for vehicles and the storage and treatment of rubble and scrap. In the next period, we plan to expand a new area of 54 thousand square meters.”

Panizzolo and Roster: successful partnership
In Kameno City, located near Burgas and its commercial port on the Black Sea, the new Panizzolo recycling plant was put into operation. The task of the plant is to treat scrap, mixed metals and armored cables obtained from various demolitions. “The project was born within a special meeting where I discussed the desire to treat this waste internally to increase production capacity and reduce company costs. Anton Alabaschev, one of my most trusted collaborators, has undertaken detailed research and market analysis. With the presentation of the most interesting companies, the name of Panizzolo Recycling Systems stood out, and, together with a second colleague Hristo Zeynelov, we started the first contacts.”

For the success of this project, the establishment of a relationship based on human value, the spirit of enterprise, professionalism and technical competence proved to be fundamental. “For us, the price has never been the main factor. We have always sought contact with people, and this is what made us choose Panizzolo Recycling Systems. We saw staff with a great desire to work and to build a truly complete plant for the recycling of mixed materials.”

The Panizzolo treatment cycle: from waste to secondary raw material
The installed system guarantees Roster Ltd a flexible and End-of-Waste treatment. Scrap is subjected to different phases: a volumetric reduction thanks to the shredding PZ 2H 1500 R (2x132kW), a grinding using the Flex 1000 hammer mill (250 kW – up to 11 ton / h) and then continuing with appropriate systems for separating the output material. An independent treatment line is part of the Panizzolo refining plant. The purpose is to enhance fractions leaving the previous plant, enhancing the granular metal such as copper, brass, aluminum and steel.

“Coming from our demolition activity, waste occurs mainly in a mixture of iron and electrical material. We needed a system that could cope with this heavy refusal, and the Panizzolo technicians were able to professionally guide us to the correct setting,” Terziev explains.

Rosen Terziev: “Panizzolo, an example of quality and professionalism”
Complying with the quality policy of Panizzolo, the introduction to the plant’s system went hand in hand with a theoretical and operational training cycle. That allowed the operators of Roster Ltd to become familiar with new technologies. “During our cooperation, I was pleasantly surprised not only by the acceptability of the pricing policy and the quality of your products but also by the high culture of communication and the professionalism of the staff,” Rosen concludes.
