GREEN-LOOP demonstrates the manufacturing of multifunctional rubber panels for the reduction of vibro-acoustics transmission loss and fire-retardant properties in the Construction sector.
These panels will be crafted from recyclable thermo-plastics and elastomers, utilizing bio-based raw materials such as lignin and natural devulcanized rubber.
After the most suitable sustainable materials combination had been selected in the laboratory, representative samples were manufactured to be integrated into real conditions tests of fire resistance and seismic response, which were demonstrated under relevant industrial conditions.
The product will be made of recyclable thermoplastics and elastomers. Bio-based raw materials will be lignin and natural rubber.
The rubber pads will be first validated at laboratory scale; once the most suitable sustainable materials combination will be selected, representative samples will be manufactured to be integrated into real conditions test of fire resistance and seismic response to be demonstrated under relevant industrial conditions.
The manufactory innovation has been driven by ultrasound technology. A parallel devulcanisation approach using ultrasonication within a green chemistry framework with a low environmental footprint has also been developed.
Characterization and standardization activities are being undertaken, and the entire value chain will be monitored by environmental and circularity partners to ensure the implementation of green manufacturing practices.
This adaptable value chain model also holds potential for replication in other sectors such as transport, automotive and marine transport trimming.
Advantage of the product over conventional materials:
- The bio-rubber panels increase structural integrity, damping and compliance to fire safety.
- No hybrid eco-elastomeric/natural fibre damping tile is currently available in the market.
