Natural Surfactants for Flotation Deinking in Paper Recycling

The objective of this research was to evaluate new types of surfactants based on renewable materials (sugar and protein-based surfactants) for use in ink removal from recycled paper via flotation deinking. By applying green chemistry approaches we aim to minimize the environmental impact of deinking agents and also to open an avenue for a number of products that are to be generated from the uti...

Vitrification of copper flotation waste.

The vitrification of an hazardous iron-rich waste (W), arising from slag flotation of copper production, was studied. Two glasses, containing 30wt% W were melted for 30min at 1400 degrees C. The first batch, labeled WSZ, was obtained by mixing W, blast furnace slag (S) and zeolite tuff (Z), whereas the second, labeled WG, was prepared by mixing W, glass cullet (G), sand and limestone. The glass...

IPST Technical Paper Series Number 867 Flotation Deinking of Old Newsprint Using Poly(Diallylmethylammonium Chloride) as a Single Deinking Agent

Flotation deinking of old newsprint (ONP) using polydiallyldimethylammonium chloride (polyDADMAC) as the only deinking agent was studied. The results demonstrate that polyDADMAC can neutralize dissolved anionics to form small particles. These small particles, together with ink, filler, and fines, strongly adsorbed onto air bubble surfaces and functioned as particle foaming agents. Therefore, no...

Role of Deinking Agent and Its Challenge

The basic deinking process for old newspapers, the role of the deinking agent, the science and the condition for good deinking are reviewed based on the results in our laboratory first. Then, by using this typical deinking process, the deinkability of the pigment―based inkjet printings was examined. In commercial printings, the transition to on―demand printings is in progress, because the on―de...
