21 Processes In Pharmaceutical Industry Goods ReceivingLaboratoryPreparationFormulationFinishingPackagingWarehouse & Distrubituon
22 Goods receiving pharmaceuticals are stored, either in the form of raw materials or packaging.It’s vital to optimally manage these materials, protect them from end to end,and systematically document them.
29 Chemical Synthesis Most drugs production Chemical synthesis process manufacturing pharmaceuticals usingorganic andinorganic chemical reactions
30 Typical manufacturing plant, one or more batch reactor vessels series of reaction,separation and purification steps desired end product
31 In drug manufacturing plant, reaction vesselsEquipments arranged into separate
32 Solvents to dissolveGaseousSolidViscous reactantsTo bring all the reactants close molecularalso serve to transmit heat to or from the reacting molecules.
33 Some solvents also control the reaction temperature. common practice in a batch-type synthesis
34 Natural Product Extraction Many materials as pharmaceuticalsderived from such natural sources;the roots,leaves of plants,animal glands,and parasitic fungi
35 numerous and diverse pharmaceutical applications, ranging from Tranquilizers and allergy-relief medicationsInsulin andMorphineBlood fractionation plasma and its derivatives.
36 Despite diversity,all extractive pharmaceuticals common characteristic:Too complex to synthesize commerciallyeither very large molecules to synthesize
37 Extraction expensive manufacturing process requires collecting and processing largevolumes of specialized plantanimal matterto produce small quantities of products.
38 FermentationMost antibiotics ,steroids and vitamin B fermentation process,two major steps:inoculum and seed preparationfermentation, followed by crude product recovery and purification
39 Sterile inoculum preparation begins in the lab withcarefully maintained population of a microbial strain.A few cells this culture matured into a dense suspension through a series of test tubes, agar slants, and shaker flasks.
40 For further propagation, the cells are then transferred to Seed tanklike a full scale fermenter and isDesigned for maximum cell growthFinal seed tank volume occupiesfrom 1 to 20% of the volume used in full scale production.
46 Finishing The best way to reliably drug finishing efficiency, quality and transparencyis through consistent,end-to-end automation solutionscan seamlessly integratecomponents from a wide range of manufacturers.
52 Potential Environmental Issues Air emissionsWastewaterSolid and hazardous wastes
53 Air emissions Volatile organic compounds(VOCs) Acid gases Particulates Greenhouse gas emissions (Combustion Source Emissions)Odorsemitted during manufacturing facilities
54 Volatile Organic Compounds significant emissions of VOCs come from1) Mostly in chemical synthesis and extraction phases
55 2) In primary pharmaceutical manufacturing ; reactor ventsfiltering systems in the separation processSolvent vapors from purification tanks and dryers (including loading and unloading operations)fugitive emissions from valves, tanks, pumps, and other equipmentprefermentation and fermentation solventswastewater collection and treatment units.
56 3) In secondary pharmaceutical manufacturing; mixing, compounding, granulation, and formulationoperations involving the use of solvents (e.g. granulation)alcoholic solutions (e.g. tablet coating)aerosol manufacturing processes.
57 How can we control the VOCs emissions? 1) Venting of emissions from sterilization chambers into control devices such ascarbon adsorptionORcatalytic converters;
58 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 VOCrecovery efficiencies.Cryogenic condensers have higher removalefficiency (up to 99 percent) but they havehigher energy requirements.
59 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.
60 Particulate MatterParticulates consisting of manufactured or in-process product can be emitted frombulk (e.g. fermentation)secondary manufacturing.The most common sources of particulatesinclude milling, mixing,compounding,formulation,tableting, and packaging.
61 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 asWet scrubbing and wet electrostatic precipitators, especiallyafter combustion / thermal oxidation treatments.
62 Combustion Source Emissions Exhaust gas emissions produced by thecombustion 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.
63 OdorsThe 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;
64 Solid and Hazardous Wastes The principal solid wastes of concern includeprocess and effluent treatment sludges,raw materials packaging wastecontainer residuesused air filter mediaOffspec and expired productslaboratory wastes
65 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.
66 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.
67 Water SupplyWater 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.
68 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.
69 Wastewater Industrial Process Wastewater Wastewater streams in pharmaceuticalsmanufacturing come from;chemical reactions streamsproduct wash waterspent acid and caustic streamscondensed steam from sterilization and strippersair pollution control scrubber releaseequipment and facility wash waterclean-in-place wastewater.
70 The main pollutants of concern in these wastewater streams from primary manufacturing (e.g.fermentation, chemical synthesis,crystallization, purification, and biological / natural extraction)parameters arebiochemical oxygen demand (BOD)chemical oxygen demand(COD)total suspended solids (TSS)AmmoniaToxicityBiodegradabilitypH.
71 Typical Wastewater Characteristic Typical amounts released with the wastewater are:25 kg/t (BOD)50 kg/t (COD)3 kg/t (TSS)0.8 kg/t phenol
72 Wastewaters produced from pharmaceutical industry may contain : mercury, in a range of 0.1–4 (mg/l),cadmium (10–600 mg/l),isomers of hexachlorocyclohexane,1,2-dichloroethane,
73 Typical wastewater treatment steps grease traps, skimmers, dissolved air floatation or oil water separators for separation of oils and floatable solids;filtration for separation of filterable solids;flow and load equalization;sedimentation for suspended solids reductionusing clarifiers; biological treatment, typically aerobic treatment for reduction of soluble organic matter (BOD)biological nutrient removal for reduction in nitrogen and phosphorus
74 biological nutrient removal for reduction in nitrogen and phosphorus using clarifiers; biological treatment, typically aerobic treatment for reduction of soluble organic matter (BOD)chlorination of effluent when disinfection is requireddewatering and disposal of residuals in designated hazardous waste landfills.
75 Additional engineering controls may be required for advanced metals removal using membrane filtration or other physical/chemical treatment technologiesremoval of recalcitrant organics and active ingredients using activated carbon or advanced chemical oxidationresidual color removal using adsorption or chemical oxidationreduction in effluent toxicity using appropriate technology (such as reverse osmosis, ion exchange, activated carbon, etc.)reduction in TDS in the effluent using reverse osmosis or evaporation
76 Pollution Prevention and Control Recommended pollution prevention and control measures include:Waste reduction by material substitution (e.g. use of water based solvents),Process modifications (e.g. continuous rather than batch operations to reduce spillage and other material losses),
77 Spent solvent recycling and reuse, through distillation,evaporation, decantation, centrifugation and filtration,Potentially pathogenic waste from biotechnology manufacturing should be inactivated through sterilization or chemical treatment before final disposal.
78 Use automated filling to minimize spillage, Use “closed” feed systems into batch reactors,Use equipment washdown waters and other process waters (such as leakages from pump seals) as makeup solutions for subsequent batches,
79 Recirculate cooling water, Use dedicated dust collectors to recycle recovered materials,Vent equipment through a vapor recoverysystem,Use loss-free vacuum pumps,
80 Return toxic materials packaging to the supplier for reuse, or incinerate it in an environmentally acceptable manner,Minimize storage time of off-specification products through regular reprocessing,Find productive uses for off-specification products to avoid disposal problems,
81 Use high-pressure hoses for equipment cleaning to reduce wastewater, Provide stormwater drainage and avoid contamination of stormwater from process areas,Label and store toxic and hazardous materials in secure, bunded areas. Spillage should be collected and reused.
