Plastic merchandise is broadly utilized on a regular basis in life, largely on account of the benefit of low cost, malleability and durability. As compared to prior 50 years, now the worldwide manufacturing of plastic is about 9.1 billion tons, with a yearly growing rate of 8.7%. As a result of huge manufacturing and inefficient management, the problem of plastic waste is no doubt a vital challenge to the surroundings. Nearly all of plastics embrace polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinylchloride (PVC) and polyethylene terephthalate (PET). Even though the recycling cost of plastic merchandise is increasing, plastics are nonetheless added into the environment. For instance, an estimated 250 million tons plastic arrived in marine environments in 2015. Within the environments, plastic litter could be degraded by physical, chemical and organic processes (i.e. ultraviolet radiation, wind or water erosion, etc) and turned into smaller plastic debris. Since micro plastics have been extensively detected in aquatic environments, they might probably be taken up by various species together with limited fish, invertebrates, shore crabs, filter feeding bivalves and so on. Micro plastics have been reported to exist in seafood, salt, honey, sugar, beer and even in drinking water. Recent research held advised that micro plastics can induce unfavourable results on organisms, corresponding to feeding disruption, reproductive reduction, intestinal damages and disturbances in vitality metabolism.

Micro plastics (MPs) are mini-scale plastic fragments with dimensions smaller than 5 mm. They are generated by manufacturing cosmetics for numerous purposes. There are about 1 g micro plastics produced by the utilization of non-public care merchandise in every American household per year. Currently, Nano plastics (NPs) are referred to as limited micro plastics in the dimensions of smaller than 0.1 mm. As a result of their low density and limited particle size, they’re simply discharged into the wastewater drainage systems. The poor degradability results in the plastic waste remaining in water for a very long time, and over time it fragments into smaller and smaller plastic particles. Wastewater therapy crops (WWTPs) are reported as the principal supply of micro plastic and Nano plastic within the effluents, since they should not be correctly designed for this purpose. The elimination of micro plastics is an extreme problem that must be solved urgently. Dynamic Membranes Technology, Ultrafiltration, Reverse Osmosis, Membrane Bioreactor (MBR) are the potential micro plastics’ therapy technologies.
