Introduction to key environmental aspects of pharmaceutical industry in India Faculty :- Mr Shridhar Rajpurohit LA (IMS )/ TUTOR /SAFETY
SOURCES OF HAZARDS IN PHARMA Manufacturing and formulation installations. Handling and storage of hazardous chemicals including warehouses, godowns, tank forms in ports/fuel depots/docks. Transportation (road, rail, air, water, pipelines). Emission of pollutants the air pollutants include carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter of 10 microns or less (PM10), total suspended particulate matter (SPM), sulphur dioxide (SO2), and volatile organic compounds (VOCs). The most common VOCs include methanol, dichloromethane, toluene, ethylene glycol, N,Ndimethylformamide ,and acetonitrile. Effluents, especially those that are not easily biodegradable and toxic in nature. The effluent releases could go directly to streams, rivers, lakes, oceans, or other bodies of water. The releases due to runoff, including storm water runoff, could also be a potential hazard. 2
HAZARDOUS WASTE TYPES these are in the form of liquids, solids, contained gases or sludge. This waste, containing spent solvents and other toxic organics in significant concentrations, requires treatment before it can be disposed of safely. The toxic releases from the pharmaceuticals industry includes on-site discharge of a toxic chemical to the environment. This includes emissions to the air, discharges to bodies of water, releases at the facility to land, as well as contained disposal into underground injection wells. Natural calamities like such as flood, cyclone, earthquake, tsunami. 3
VARIOUS TYPES OF PHARMACEUTICAL WASTE CHEMICAL WASTE Organic chemical residues from manufacturing processes Heavy metals Dust during formulation Gaseous Vapours / emissions during API /Bulk drugs Chemical Spills Leakages water , oils, solvents , chemicals , 4
EXAMPLES OF CHEMICAL WASTE Carcinogenic & other Chemicals used will explore every chances of gaseous/ fumes for Aromatic Amines , Benzene derivatives ,Solvents like Acetonitrile , Acetic Acid , Toluene, Methanol . All are very hazardous for Environment & Occupation . Needs Control measures especially in terms of EMS i.e. Environment Management System ( ISO 14001) and OHSAS 18001 . 5
MOST COMMON ENVIRONMENT HAZARDS BY PHARMA FIRM The hazards from the pharmaceuticals could be categorized as: Ecotoxic - damage is caused to the environment. Carcinogenic - contribute to the causation of cancer. Persistent - remain dangerous for a long time. Bio-accumulative accumulates as it makes its way up the food chain. Disastrous due to a catastrophe, mishap, calamity or grave occurrence in any area. 6
CONTD. Water Pollution because of spillage , drains and generation of effluent water , sewage water for uncontrolled pH , and treating it ineffectively . MOST dangerous for aquatic living organisms or their livelihood. Air Pollution releases of gaseous , fumes , dust , particulates to atmosphere , poor air quality , Land /Soil Pollution Spillage , chemicals , oils , lubricants leakages to land /soil seepage causation of non fertility to soil /lands , dumping or disposal of incinerated sludge unauthorized Noise Pollution persistent vibration in operating machines , equipments , use of non acoustic power generators , air compressors . 7
CONTD. Odor :- spillage of blood , bio medical waste and culture burning in autoclave etc -poor effect on ambient air quality , -leading to mass air pollution and hazards to neighborhood plants , trees, human , animals etc . GLOBAL WARMING CO2 Emission , CO , suspended particulates in atmosphere , NOx , - very sensitive issue globally now posing great threat of GLACIAL melting Heat Stress :- Uncontrolled work environment , high temp , exothermic reactions , use of solvents , - very dangerous occupational hazard and also affecting ENVIRONMENT 8
