Abstract

Recycled glass cullet was sintered from green compacts with 0.5 and 1% by weight respectively of organic binders added: polyvinyl alcohol (PVA), and sodium silicate (Na2SiO3). Typically, glass is recycled by melting, requiring large amounts of energy from fossil fuels adding to greenhouse emissions. Disc shaped compacts with a 13 mm diameter, formed by uniaxial pressing, were sintered at temperature of 680, 700, and 720 °C for 60 min. The recycled material with 1 wt% sodium silicate binder sintered at 700 °C has the highest tensile strength; more important, in the range of regular soda-lime glass, suggesting a greenhouse gas reduction using this sintering process.
