Researchers transform pulp waste into industrial …

Fly ash is 10 times more effective than existing filters. The pellets could potentially be used in air filters as deodorizers for pulp mills or water treatment plants, where bacterial fermentation also creates smelly, sulphur-based compounds. They could also be used to remove hydrogen sulphide and potentially, carbon dioxide, from sour gas.
