In recent years, there has also been a growing interest in the development of greener and more sustainable methods for API production. This includes utilizing environmentally friendly solvents, reducing waste, and employing energy-efficient processes. The pharmaceutical industry is under pressure to adopt sustainable practices, not only to protect the environment but also to improve public perception and meet regulatory requirements.
Chemical precipitation is another key method, where chemicals are added to form insoluble compounds that can be removed from the water. This process is particularly effective for removing heavy metals from industrial wastewater. By adjusting the pH and adding precipitating agents, contaminants can be converted into a solid state and subsequently separated from the water.
