AB This study investigates the manufacture and environmental assessment of acoustic insulation foams made fromrecycled polyethylene (RM) from packaging film waste. Blends of RM with virgin polyethylene (PE) andethylene-vinyl acetate (EVA) were used to produce cellular structures through chemical (Ch) and physical (Ph)foaming processes. The aim was to develop materials with properties comparable to commercial acousticinsulation products in construction sector, assessing structural integrity and acoustic performance via dynamicstiffness. Products with performance like the commercial were achieved with recycled content ranging from 40 to80 wt%. These successful cases were also evaluated for environmental impact. The life cycle assessmentconsidered two approaches: one analysing the production of 1 kg of foam (standardized density values), wherephysical foaming showed a lower environmental footprint, and the other evaluating the mass needed to achievethe dynamic stiffness of the commercial reference (empirical density values), which favoured chemical foamingfor producing foams with comparable properties but lower densities. Although physical foaming has environ-mental advantages, the higher densities achieved with RM limit its viability. Consequently, chemical foaming ismore environmentally favourable due to lower material consumption. Therefore, Ch_RM:EVA,80:20 is optimalfor technical requirements, while Ch_RM:PE,40:60 is more environmentally advantageous. The compromisesolution that addresses both technical and environmental aspects is Ch_RM:EVA,40:60. This foam showedacoustic performance equivalent to the commercial, achieved through a manufacturing process and recycledcontent minimizing environmental impacts. Furthermore, transforming packaging waste into a long-lastingproduct also reduces waste accumulation and delays non-sustainable but necessary processes like energygeneration.
