Fly ash finds a number of uses, almost always outside of the Paper Industry. Here the authors take fly ash from a coal-fired power station and co-flocculate it with cellulose fines to produce larger aggregates that are better retained during paper formation. In addition, within defined limits, they have no negative impact on paper strength. This is an excellent example of pushing the envelope of what is possible as regards recycling of what has previously been defined as a ‘waste’ material.

The Paper Industry Technical Association (PITA) is an independent organisation which operates for the general benefit of its members – both individual and corporate – dedicated to promoting and improving the technical and scientific knowledge of those working in the UK pulp and paper industry. Formed in 1960, it serves the Industry, both manufacturers and suppliers, by providing a forum for members to meet and network; it organises visits, conferences and training seminars that cover all aspects of papermaking science. It also publishes the prestigious journal Paper Technology and the PITA Annual Review , both sent free to members, and a range of other technical publications which include conference proceedings and the acclaimed Essential Guide to Aqueous Coating .
