Hydrophobic concrete using waste paper sludge .

01.04.2015· Paper sludge ash (PSA) is a waste generated by the paper recycling industry. It is produced when dewatered waste paper sludge, a by-product of the de-inking and re-pulping of paper, is combusted to reduce waste volume and to produce energy. The combustion process is regulated in the EU and typically uses fluidised bed combustion at ~ 850 °C to 1100 °C. The UK produces ~ 125,000 .
