Clinical waste

Stationary sources Waste incineration Steel industry Recycling plants Energy production Municipal solid waste, clinical waste, hazardous waste, sewage sludge Steel mills, sintering plants, hot-strip mills Non-ferrous metals (melting, foundry Al, Cu, Ptx, Zn, Sn) Fossil fuel power plants, wood combustion, landfill gas... 

PCDD/Fs are produced in trace quantities, and the demand for HC1 participating in the chlorination reactions is correspondingly very small. While removal of materials such as PVC could potentially result in a significant reduction in the total amount of HC1 generated by the combustion of MSW in the furnace, this will not necessarily impact on the small quantity required for PCDD/F formation. In other words, there is sufficient chlorine present in the remaining MSW, clinical waste or other waste-based feedstock after removal of PVC to satisfy the requirements of the PCDD/F formation reactions, even under optimum formation conditions. PVC/plastics removal is therefore unlikely to affect emissions of PCDD/Fs, all other operational conditions remaining constant. 

Different types of waste will require different handling techniques. For example, clinical waste is invariably sealed at source, and shredding of this material prior to it being fed into the combustor would not be considered good practice. The principle, that the combustor and associated handling requirements should reflect the type of waste to be treated, remains an important consideration for the control of PCDD/F emissions. 

Adsorptive Processes. The use of activated carbon, sprayed into a dry/semi dry scrubbing unit along with lime or less frequently packed in an adsorption unit positioned after the particulate removal device and prior to the stack, has become a standard component in gas cleaning trains as a means of PCDD/F control on all sizes of plant fed with MSW or clinical waste. Other adsorptive media such as zeolites are also being tested. The inclusion of an adsorptive device in combustion systems fired with wood and agricultural wastes is not normally contemplated, and as noted above, an interesting issue to be resolved is whether different waste types generate flyash of different activities relative to PCDD/F formation.

Infectious waste syn. biomedical waste, clinical waste, or medical waste. 

Clinical Waste and Medical Waste Wastes transported under UN3291 are wastes derived from the medical treatment of humans or animals or from bio-research, where there is a relatively low probability that infectious substances are present. Waste infectious substances which can be specified must be assigned to UN2814 or UN2900. Decontaminated wastes which previously contained infectious substances may be considered as not subject to these Regulations unless the criteria of another Class or Division are met. lATA 3.6.2.1.5... 

PCDDs and PCDFs constitute a class of ubiquitous pollutants with aromatic structure, high chemical stability and extremely poor water solubility. They can occiu in the form of 75 PCDD congeners and 135 PCDF congeners (Table 1). At present, most PCDD and PCDF soinces are well characterized. These sources include chemical, thermal, photochemical and enzymatic reactions. Combustion processes, mainly incineration plants such as municipal solid waste incinerators, clinical waste incinerators and industrial waste incinerators are known to be some of the most important sources responsible for the presence of these contaminants in the environment.

The most effective control measures which can reduce the risk of Infection from biological organisms are disinfection, proper disposal of clinical waste (Including syringes), good personal hygiene and, where appropriate, personal protective equipment. Other measures include vermin control, water treatment and immunization.

In 1995, in the United Kingdom the dominant source was the incineration of solid municipal waste, contributing an average of 70 % to the atmospheric emissions. Other major emissions are from sinter plants (steel mills), combustion of coal, emissions from iron and steel plants, from non-ferous metal operations, and combustion of clinical waste, summing up to 23% of total industrial emissions [389].

Contact transmission will be the chief cause of infection spread between individuals. Following universal precautions, additional contact precautions should be maintained to minimise transmission. This may include isolation of patients in private rooms where resources allow. All health workers should wear gloves and a gown for any patient contact. Face shields and eye protection should also be worn when conducting an examination or procedure that may involve aerosols or droplet formation, such as airway suctioning or the use of nebulisers. PPE should be removed between patients, with respiratory protection removed last, and disposed of appropriately in marked clinical waste bins.
