Researchers have managed to convert fibers from orange tree prunings into boards that provide a 150% improvement in acoustic insulation compared to conventional gypsum boards.

An article in Phys.org explains how researchers from the Universitat Politècnica de València and the Universitat de Girona in Spain used classic orange tree prunings which were put through a defibration process and combined with polypropylene to produce acoustic boards.

Dr. Pere Mutjé, Head of the LEPAMAP Group at the Universitat de Girona said the research is a leading example of developing eco-friendly materials.

The research, which makes use of agriculture byproduct, has been published in the Journal of Construction and Building Materials.
