Potential Environmental Issues
Air emissions Wastewater Solid and hazardous wastes
![Page 53: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/53.jpg)
Air emissions
Volatile organic compounds(VOCs) Acid gases Particulates Greenhouse gas emissions (Combustion
Source Emissions) Odors
emitted during manufacturing facilities
![Page 54: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/54.jpg)
Volatile Organic Compounds
significant emissions of VOCs come from
1) Mostly in chemical synthesis and extraction phases
![Page 55: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/55.jpg)
2) In primary pharmaceutical manufacturing ; reactor vents filtering systems in the separation process Solvent vapors from purification tanks and
dryers (including loading and unloading operations)
fugitive emissions from valves, tanks, pumps, and other equipment
prefermentation and fermentation solvents wastewater collection and treatment units.
![Page 56: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/56.jpg)
3) In secondary pharmaceutical manufacturing;
mixing, compounding, granulation, and formulation
operations involving the use of solvents (e.g. granulation)
alcoholic solutions (e.g. tablet coating)
aerosol manufacturing processes.
![Page 57: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/57.jpg)
How can we control the VOCs emissions?
1) Venting of emissions from sterilization chambers into control devices such as
carbon adsorption
OR
catalytic converters;
![Page 58: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/58.jpg)
2) Condensation and distillation of solvents emitted from reactors or distillation units.
Possible installation of cryogenic condensersthat can reduce the gas stream temperaturebelow dew point to achieve higher VOC recovery efficiencies. Cryogenic condensers have higher removalefficiency (up to 99 percent) but they have higher energy requirements.
![Page 59: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/59.jpg)
3) Installation of wet scrubbers (or gas absorbers), which may remove VOCs as well as other gaseous pollutants from a gas stream.
Also, addition of hypochlorite to the scrubber inorder to reduce emissions of nuisance odors; WHAT IS SCRUBBER? Water, caustic, and acidic scrubbers are widely used for
organic and inorganic gas emission reduction. Acid gas emissions are controlled through water and caustic scrubbing systems (often several scrubbersin series). Scrubbers create a wastewater stream requiring further treatment.
![Page 60: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/60.jpg)
Particulate Matter
Particulates consisting of manufactured or in-process product can be emitted from
bulk (e.g. fermentation) secondary manufacturing. The most common sources of particulates include milling,
mixing,compounding,formulation, tableting, and packaging.

Recommended particulate matter management :
Collection of particulates through air filtration units, typicallybaghouse / fabric filters.
Depending on the volume of emissions and size of particulate matter, additional particulate emissions control methods should be considered,
such as Wet scrubbing and wet electrostatic precipitators, especiallyafter combustion / thermal oxidation treatments.
![Page 62: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/62.jpg)
Combustion Source Emissions
Exhaust gas emissions produced by the
combustion of gas or diesel in turbines, boilers, compressors, pumps and other engines for power and heat generation, are a significant source of air emissions from pharmaceuticals manufacturing facilities.
![Page 63: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/63.jpg)
Odors
The main source of odor emissions is typically associated with fermentation activities.
Recommended odor management strategies include: Post-combustion of venting gases; Use of exhaust stack heights that are consistent withpractices as described in the regulations. Use of wet scrubbers to remove odors with a high
affinity to water;

Solid and Hazardous Wastes
The principal solid wastes of concern include
process and effluent treatment sludges,
raw materials packaging waste
container residues
used air filter media
Offspec and expired products
laboratory wastes
![Page 65: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/65.jpg)
Approximately 200 kg wastes per ton of product of waste are generated.
Hazardous and non-hazardous industrial wastes should be stored, transported, and managed as described in the regulations.
![Page 66: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/66.jpg)
Treatment of solid wastes
Contaminated solid wastes are generally incinerated,and the flue gases are scrubbed.
Combustion devices should be operated at temperaturesabove 1,000° C, with a residence time of at least 1 second,to achieve acceptable destruction efficiency(over 99.99%) of toxics.
![Page 67: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/67.jpg)
Water Supply
Water is generally needed both for the process (e.g., dilution) and for other uses including cooling water, deionized water, equipment and piping cleaning water, etc.
Water for injection is used for manufacture of injectable products and in any process where sterile conditions are needed.
![Page 68: PHARMACEUTICAL INDUSTRY Prepared by A.Erenşah Kaya Hande Kartal Merve Maçin Züleyha Atlay.](https://reader038.fdocuments.net/reader038/viewer/2022103015/551998c455034648068b48c4/html5/thumbnails/68.jpg)
Water purity is obtained by deionized water distillation or by double reverse osmosis.
The storage tank is blanketed with pure nitrogen or air.
Piping and storage are maintained at a temperature higher than 80°C, and water is continuously recycled to avoid contamination.
