Standards and regulation in the pharmaceutical industry 

Liquid emissions and waste water

In the pharmaceutical industry, liquid emissions are mainly related to solvents, and waste water that can be contaminated with organic and inorganic chemicals, metals, pharmaceutical compounds, and often mixture of all of them, which are formed in primary or secondary manufacturing.  

Water is a critical resource in the pharmaceutical industry, serving as a solvent and cleaning agent but also for temperature regulation (e.g. cooling). However, improper management can lead to significant environmental pollution. The management and treatment of aqueous waste from the pharmaceutical industry in Europe involves several key considerations and technologies to ensure environmental protection and compliance with regulations. Efforts to optimise water use in processes and minimise wastewater are also essential for aligning with green chemistry principles. 

Best Available Techniques for managing wastewater and waste gases in the chemical sector have been established, highlighting the importance of environmental management systems, water saving, wastewater management, collection, and treatment. Understanding the composition of the pollutants is crucial for implementing the most effective treatment techniques and ensuring compliance with environmental standards. 

The importance of effectively managing wastewater in the pharmaceutical industry cannot be overstated, as it plays a critical role in preventing the discharge of toxic substances into the environment. These substances, if not properly treated, can have detrimental effects on aquatic ecosystems, including promoting antibiotic resistance and causing endocrine disruption among aquatic species. Furthermore, ensuring that pharmaceutical wastewater is appropriately treated is essential for compliance with stringent environmental regulations, which aim to safeguard public health by preventing the contamination of drinking water sources. By investing in efficient wastewater treatment technologies and strategies, the pharmaceutical industry can mitigate its environmental impact and ensure long-term ecological and public health benefits.
