Method to recycle corrugated cardboard in eco-friendly composites

Abstract

This study aims to explore a sustainable method for recycling corrugated cardboard into eco-friendly composites and their potential uses in different applications. Two types of composites made from recycled cardboard (printed and unprinted) were produced and compared in terms of density, dimensional stability, modulus of elasticity (MOE), modulus of rupture (MOR), internal bonding strength (IB), thermal conductivity, and sound absorption. Samples made from unprinted cardboard demonstrated better overall performance in terms of density, thermal insulation and sound absorption. In contrast, composite B, derived from printed cardboard, exhibited greater strength. The findings suggest these materials can be viable alternatives for thermal insulation panels and acoustic panels.
