Treatment of Microplastics from Pharmaceutical Industrial Wastewater
AI summary Read the abstract
Pharmaceutical manufacturing generates wastewater containing microplastics from plastic equipment, packaging, and processing materials, a source of contamination that surged during the COVID-19 pandemic as drug production ramped up. This review examines the nature of microplastic contamination in pharmaceutical wastewater and evaluates treatment techniques for removing these particles before discharge. Addressing this overlooked industrial source is important for reducing microplastic loads entering water systems from healthcare and pharmaceutical infrastructure.
The ubiquity of microplastics in the effluents produced during pharmaceutical manufacturing operations has made the presence of these particles in pharmaceutical industry wastewater a significant environmental concern. The growing importance of the pharmaceutical sector emphasizes even more how urgent it is to address microplastic contamination as a serious environmental issue that has to be addressed right now and requires the application of efficient mitigation techniques. During the pandemic, a significant increase in microplastics was found in pharmaceutical industry trash. It is imperative to address the issues brought on by the varied makeup of microplastics obtained from the pharmaceutical sector. Identification and classification procedures become more difficult when polymers are added to medication formulations, packaging materials, and equipment because they combine to generate a complex mixture of microplastics. Investigating tactics that combine bio-based adsorbents with nanomaterials is crucial since these methods have shown promise in lab settings and may be solutions. Present wastewater treatment techniques, such as membrane filtration, activated carbon adsorption, and ultrasonic degradation, have the potential to enhance efficacy of removal of microplastic from wastewater. They do, however, have limits in terms of completely getting rid of microplastics. For example, ozonation can change a polymer’s structure without appreciably lowering the presence of microplastic residues. Thus, more sophisticated approaches have been devised to intensify the treatment of microplastics, such as the utilization of magnetic polyoxometalate-supported ionic liquid phases. The treatment of microplastics from pharmaceutical industry effluent necessitates a thorough and interdisciplinary approach, as this chapter emphasizes. Through the adoption of technological innovations, strict regulations, and sustainable practices, the pharmaceutical business may effectively contribute to reducing the environmental impact of microplastics and promoting a cleaner, more sustainable future.

The Occurrence of Micropollutants in the Aquatic Environment and Technologies for Their Removal
AI summary Read the abstract
This review summarizes the growing problem of micropollutants in water, including microplastics, pharmaceuticals, and industrial chemicals, and evaluates advanced treatment methods to remove them. The research is important for human health because conventional water treatment plants cannot effectively filter out these contaminants, meaning people may be regularly exposed through tap water.
An Overview of the Analysis, Distribution, and Treatment of Microplastics in Industrial Wastewater
AI summary Read the abstract
Tiny plastic particles called microplastics are polluting our water supply through industrial wastewater, and they can carry harmful chemicals, antibiotics, and heavy metals that build up in our bodies over time. This review paper rounds up existing research on ways to filter these particles out of wastewater—like special membranes and advanced filtering systems—before it re-enters our environment and water sources. The takeaway: while current treatment methods are imperfect and costly, scientists are actively developing better filtration technology to keep these pollutants out of the water we depend on.
Hidden pathways: Detection and quantification of microplastics across treatment stages of pharmaceutical WWTPs
AI summary Read the abstract
Pharmaceutical factories are releasing tiny plastic particles into wastewater, and even after treatment, more than half of these particles still make it through into rivers and streams. Researchers found the water leaving these plants still contained hundreds of microplastic particles per liter, mostly tiny white plastic fragments that can break down further once released into the environment. This matters because as these microplastics spread through waterways, they can accumulate in fish and other wildlife, eventually working their way into the food we eat and raising concerns about long-term health effects.
