New Enviro-Friendly Absorbent Acoustic Panels

The main objective of this project is the development of innovative acoustic panels using recycled rubber from outof- service tyres and specific designs in order to reduce raw material dependence and environmental impact of concrete panels while providing a competitive product with better sound absorption performance than neat concrete acoustic panels used for noise reduction. The current European Framework Directive (Directive 2006/12/EC) places the emphasis on the need to establish waste schemes for end-of-life tires. End-of-life tires offer a significant opportunity for achieving sustainable development objectives. Widespread use in energy and material recovery applications is well-established as an alternative to virgin raw materials. Using recycled rubber material in some products can also improve the properties of that end product, as it is the case of the noise barriers that will be developed in the present project.
