From waste to value – Circular economy approaches in noise barrier production

The circular economy is increasingly recognized as a sustainable alternative to the traditional linear economy, which follows a "take-make-dispose" model. In Slovakia, several companies have embraced circular practices, including Bamida, a Prešov-based producer of noise barriers. In collaboration with the Faculty of Management and Business, Bamida has integrated circular economy strategies, prioritizing resource efficiency, waste reduction, and innovative material reuse.
The company repurposes recycled textile waste in its noise barriers and aims to close its production loop by using manufacturing waste for secondary products. For example, PVC textiles that would normally be discarded are transformed into floating trash barriers to trap pollutants in watercourses and reservoirs, reducing environmental pollution. This approach not only cuts waste but also adds environmental and economic value.
Bamida uses tools like the Circular Canvas Model to identify areas for improving circularity in its operations. As it refines its processes, the company explores opportunities for multi-circularity, where waste is converted into materials for new products.
The positive outcomes of this practice are multifaceted: reduced waste, cost savings, and a reduced carbon footprint. Additionally, this model offers insights and scalable solutions that can be applied across other industries, making it a replicable example of circular economy in practice not only within Slovakia.
