As part of the contract for the supervision of the construction of the Buzău–Focșani Motorway, Lot 1: Buzău–Vadu Pașii, part of the A7 corridor, the second workshop for a group of employees of CNAIR – Compania Națională de Administrare a Infrastructurii Rutiere, the National Company for Road Infrastructure Administration of Romania, was held in Ohrid from 30 September to 3 October.

The workshop, on the topic of “Circular Economy and the Use of Renewable Materials in Construction," was organised by the Civil Engineering Institute Macedonia – CEIM and the Institute for Research in Environment, Civil Engineering and Energy – IECE. It was led by Prof. Dr. Angelina Taneva-Veshoska, with the participation of CEIM experts specialising in relevant areas of civil engineering and infrastructure.

The workshop brought together 20 representatives of CNAIR, including directors and managers from the technical and project implementation departments, as well as representatives from the finance department.

The programme addressed a range of current topics, including:

- new sustainable materials for road construction;
- circular economy principles and their application in the construction sector;
- new opportunities for integrating circular economy approaches into road infrastructure;
- an integrated methodology for assessing slope instability risks in low-quality rock masses;
- a case study of the Kičevo – Ohrid Motorway, followed by a site visit.

The workshop created a valuable opportunity for CEIM experts and CNAIR professionals to share practical experience, knowledge, and best practices, while discussing how modern and more sustainable approaches could be integrated into future infrastructure projects.
