Plastics are ubiquitous in our society and are used in many industries, such as packaging, electronics, the automotive industry, and medical and health sectors, and plastic waste is among the types of waste of higher environmental concern. The increase in the amount of plastic waste produced daily has increased environmental problems, such as pollution by micro-plastics, contamination of the food chain, biodiversity degradation and economic losses. The selective and efficient conversion of plastic waste for applications in environmental remediation, such as by obtaining composites, is a strategy of the scientific community for the recovery of plastic waste. The development of polymeric supports for efficient, sustainable, and low-cost heterogeneous catalysts for the treatment of organic/inorganic contaminants is highly desirable yet still a great challenge; this will be the main focus of this work. Common commercial polymers, like polystyrene, polypropylene, polyethylene therephthalate, polyethylene and polyvinyl chloride, are addressed herein, as are their main physicochemical properties, such as molecular mass, degree of crystallinity and others. Additionally, we discuss the environmental and health risks of plastic debris and the main recycling technologies as well as their issues and environmental impact. The use of nanomaterials raises concerns about toxicity and reinforces the need to apply supports; this means that the recycling of plastics in this way may tackle two issues. Finally, we dissert about the advances in turning plastic waste into support for nanocatalysts for environmental remediation, mainly metal and metal oxide nanoparticles.

“…Aji et al, demonstrated the feasibility of waste PVC to be utilized as a polymer source for UF membrane [150]. Prior to membrane fabrication through phase-inversion technique, PVC waste collected from post-consumer disposal was dissolved in DMF, and different concentrations of CA were added to overcome the hydrophobicity of PVC.…”

Waste Reutilization in Polymeric Membrane Fabrication: A New Direction in Membranes for Separation

2021

In parallel to the rapid growth in economic and social activities, there has been an undesirable increase in environmental degradation due to the massively produced and disposed waste. The need to manage waste in a more innovative manner has become an urgent matter. In response to the call for circular economy, some solid wastes can offer plenty of opportunities to be reutilized as raw materials for the fabrication of functional, high-value products. In the context of solid waste-derived polymeric membrane development, this strategy can pave a way to reduce the consumption of conventional feedstock for the production of synthetic polymers and simultaneously to dampen the negative environmental impacts resulting from the improper management of these solid wastes. The review aims to offer a platform for overviewing the potentials of reutilizing solid waste in liquid separation membrane fabrication by covering the important aspects, including waste pretreatment and raw material extraction, membrane fabrication and characterizations, as well as the separation performance evaluation of the resultant membranes. Three major types of waste-derived polymeric raw materials, namely keratin, cellulose, and plastics, are discussed based on the waste origins, limitations in the waste processing, and their conversion into polymeric membranes. With the promising material properties and viability of processing facilities, recycling and reutilization of waste resources for membrane fabrication are deemed to be a promising strategy that can bring about huge benefits in multiple ways, especially to make a step closer to sustainable and green membrane production.

Dairy industry wastewater was treated by a micellar-enhanced ultrafiltration (MEUF) process. Sodium dodecylbenzene sulfonate and Tween-80 were used as anionic and non-ionic surfactants, respectively, along with the dairy industry wastewater sample. A deep eutectic solvent (DES) membrane was prepared by phase inversion via non-solvent immersion precipitation. The DES (choline chloride/urea) as pore-forming agent was synthesized and added into the casting solution at various concentrations and blended to form a membrane, using a dead-end filtration setup. The prepared membranes were characterized to examine the presence of functional groups and the surface morphology. The permeate flux and rejection performance of the prepared membranes were investigated. The newly developed MEUF membrane is promising for the treatment of dairy effluents.
