Separating different components of a plastic mixture is crucial in its recycling. Among the different separation techniques, flotation was selected as a cheap, non-toxic, and efficient process. Basis of the technique refers to the selective adsorption of a depressant on the plastics surface which cause the alteration in the surface energy of the plastic. Adsorption of the lignosulfonic acid sodium salt (SL) on the surface of the selected available plastics in the waste stream was studied. Plastics used in this study were Polyvinylchloride (PVC), acrylonitrile-butadiene-styrene polymer (ABS), polystyrene (PS), polypropylene (PP), polyoxymethylene (POM), and polycarbonate PC. It results showed that SL adsorbed on the surface of the selected plastics considerably. It was evidenced by the measured equilibrium adsorption capacities ( [Formula: see text] ) of the SL and also, the SEM and AFM images. SL adsorbed on the plastic surface in the sequence of [Formula: see text]. Also, the parameters of the Freundlich and Langmuir adsorption models were derived. Experimental data fit with the mentioned models appropriately. However, for the most studied plastics, the Freundlich model was more suitable. As important conclusion, PP separated from plastics mix using the flotation separation technique with the aid of SL as a depressant.

“…This method of using as an additive cannot be used on a large scale, so there is no effective utilization of the by-products made from lignin black liquor. As a product of lignin sulfonation, sodium lignosulfonate inherits a three-dimensional structure and diversified functional groups of lignin, and due to the introduction of sulfonic acid groups, sodium lignosulfonate has stronger compatibility than lignin and can be used more easily as a substrate for biomass composites [ 12 , 13 ]. Therefore, the strategy of using sodium lignosulfonate to prepare biomass composites is feasible [ 14 , 15 , 16 ].…”

The development of the paper industry has led to the discharge of a large amount of papermaking waste liquid containing lignosulfonate. These lignin black liquids cause a lot of pollution in nature, which runs counter to the current environmental protection strategy under the global goal. Through the development and use of lignosulfonate in papermaking waste liquid to increase the utilization of harmful substances in waste liquid, we aim to promote waste liquid treatment and reduce environmental pollution. This paper proposes a new strategy to synthesize novel glue-free biocomposites with high-performance interfacial compatibility from papermaking by-product sodium lignosulfonate/chitosan (L/C) and waste bamboo. This L/C bamboo biocomposite material has good mechanical properties and durability, low formaldehyde emissions, a high recovery rate, meets the requirements of wood-based panels, and reduces environmental pollution. This method is low in cost, has the potential for large-scale production, and can effectively reduce the environmental pollution of the paper industry, promoting the recycling of biomass and helping the future manufacture of glue-free panels, which can be widely used in the preparation of bookcase, furniture, floor and so on.
