Vitrocrystalline foams produced with EPS as pore former: Processing and characterization

•Vitrocrystalline foams were successfully produced from recycled glass bottles.•The production of vitrocrystalline foams is an environmentally responsible way for glass and EPS powder beads recycling.•EPS powder beads (10–40 vol.%) were used as pore former to tailoring the porosity (72 up to 90%) of...

Description
Summary:•Vitrocrystalline foams were successfully produced from recycled glass bottles.•The production of vitrocrystalline foams is an environmentally responsible way for glass and EPS powder beads recycling.•EPS powder beads (10–40 vol.%) were used as pore former to tailoring the porosity (72 up to 90%) of the foams.•Vitrocrystalline foams exhibiting expressive compressive strength ∼2.75 MPa were manufactured.•Samples with suitable thermal conductivity ∼0.06 W/m·K for thermal insulation application were obtained. In this work, discarded soda-lime-silica glasses (from glass bottles) and expandable Styrofoam, EPS (d50
