Pharmaceutical waste management:

Pavani Asst Prof GRCP,Hyd Pharmaceutical waste management

PHARMACEUTICAL WASTE COMPOSITION:

PHARMACEUTICAL WASTE COMPOSITION Organic chemical residues from manufacturing processes Heavy metals Returned pharmaceuticals Expired/Unused/half used medications Test animal remains Biological products including materials extracted from biological materials such as vaccines, serums, and various plasma derivatives.

Treatment or Disposal:

Treatment or Disposal There is not much treatment of solid pharmaceutical waste. Most of the time solid waste is disposed of. Separation and reprocessing of some of the solid waste also done for recycling purpose. Incineration and landfilling of pharmaceutical solid waste is most common.

MAJOR TYPES OF INCINERATORS:

MAJOR TYPES OF INCINERATORS Grate Type of Incinerator It is a low temperature incinerator. It is useful for volume reduction of bulky waste. Hearth-Type Incinerator Most solid hazardous waste is burned in hearth-type systems Fludized-Bed Incinerator Liquids, sludges as well as uniformly sized solids can be incinerated in it

AIR POLLUTION CONTROL FROM PHARMACEUTICAL GASEOUS EMISSION:

AIR POLLUTION CONTROL FROM PHARMACEUTICAL GASEOUS EMISSION Air pollution may results from the exhaust gases release, during incineration operation Release of pharmaceutical gases into the atmosphere is strongly prohibited and air pollution control is required

PowerPoint Presentation:

Most of incinerator air pollution control systems required two functional elements particulate removal from fuel gases removal of acid gases Particulate and acid gases are usually controlled with scrubbers. These scrubbers operate on two mechanisms: physical removal of particulate, and chemical removal by absorption and neutralization of the acid gases

Objectives can be achieved by the use of :

Objectives can be achieved by the use of Afterburners ( Sec. Combustion Chamber ) It is required for solid hazardous waste incineration because the primary chamber does not provide enough time, turbulence or temperature to destroy the organic components of the waste to the required Destruction and Reduction Efficiency (DRE).

Steps for the disposal of solid pharmaceutical waste (Nemerow, 1978):

Steps for the disposal of solid pharmaceutical waste (Nemerow, 1978) Landfill disposal : Common land filling methods are Mixing with soil Shallow burial Combination of these

PowerPoint Presentation:

Deep-well disposal Material pumped into subsurface rock separated from other groundwater supplies by impermeable rock or clay. (In USA more than 100 wells are used for disposal) Land burial disposal Disposal accomplished by either near-surface or deep burial In near-surface burial material could be disposed directly into the ground or is disposed in stainless steel tanks or concrete lined pits beneath the ground. At the present time, only near surface burial is used for disposal of pharmaceutical wastes

PowerPoint Presentation:

Ocean dumping and detonation are some of expensive waste disposal methods Detonation is a processes of exploding a quantity of waste with sudden violence Thermal Shock Mechanical Shock Electrostatic charge This method mainly used for flammable and volatile waste materials
