Production of Lightweight Fillers from Waste Glass and

 · The production of high-performance lightweight fillers (LWFs) using mixed colour recycled glass and paper sludge ash (PSA) has been investigated. PSA has low sintering activity at temperatures below 1200 °C and therefore glass was added to promote liquid-phase sintering. This allows sintering to occur with simultaneous gas evolution from the decomposition of calcium carbonate present in PSA
