Abstract:
Pulp and paper industry fly ash is categorized as B3 waste, namely hazardous and toxic waste. Liquid waste produced by the pulp and paper industry contains pollutants that are toxic and can cause pathological and histopathological changes in important tissues such as the gills of fish that live in the waters around the disposal. The purpose of this study was to analyze the histology of tilapia on the performance results of fly ash adsorbents in the management of liquid waste in the pulp and paper industry.

Abstract:
Fly ash is generally obtained as a by-product from the combustion of coal and other waste materials. It is used for making bricks, but it has few limitations. The fly ash consists of Silica, Alumina, and other metal oxide components in minor quantities. Fly ash particles are observed in the range of nanometers to micrometers and can act as a catalyst in various reactions. The use of low-cost catalysts in the pyrolysis of thermoplastic waste would achieve a high percentage of low molecular weight fractions in liquid form which increases its applicability in commercial sectors.
