Before we dive in hazardous waste shredding and hazardous waste disposal, let’s go though what hazardous waste is.

It is a trend that governments in the globe emphasize on hazadous waste collection and recycling. Hazardous waste that is not well-treated pollutes the atmosphere, water, soil, etc. The mistreatment will cause ecological damage and social disuption. It becomes a bottleneck that restricts economic activities.

Examples of Hazardous Solid Waste

  • Plastic drums and metal barrels
  • Needles, syringes, expired medication.
  • Aerosol spray and gas cylinder.
  • Industrial waste like paint bucket.
  • Firearms and ammunition.
  • Radioactive waste.
  • Chemical waste.

The Physcial Treatment of Hazardous Waste

The hazardous waste is collected in a secure and confined space, awaiting for sterilization and shredding (if needed). Sterilization takes place in a autoclave at high temperature and high pressure to kill all germs. This necessary step reduce the risks of cross-containmination and infection.

Shredding hazardous waste should take extra care, because the process causes dust and splash, both are dangerous in the air. The shredding downsizes the hazardous waste, making people easy to transport waste. The final shredded particles are uniform in size and become a perfect source of RDF. The burning of wastes produced by hospitals, veterinary facilities, and medical research facilities generates energy to produce electricity.

What are the 5 Catagories of Hazardous Waste?

  1. Corrosive – with acid or alkali properties, can make toxic metals free; can corrode disposal, storage, transportation and management equipment; accidentally destroy human or animal body tissues of waste materials. Usually the pH value of the prepared solution is greater than 12.5 or less than 2.
  2. Toxic – a waste material that is hazardous or potentially hazardous to environmental organisms and human health and may cause health damage or death after swallowing, inhalation or exposure.
  3. Leaching toxicity – according to the specific experimental method to simulate the natural acid rain conditions of the sample for oscillation leaching, the leachate composition analysis, any one exceeds the criteria in the table that meet.
  4. Flammable – refers to the nature of easy to catch fire and maintain combustion, solid, liquid, gaseous state. Closed cup test flash point less than 60 degrees Celsius.
  5. Explosivity – refers to the nature of easy to explode or violent reaction, or reaction will volatilize toxic gases or fumes.
  6. Infectious – refers to bacteria, viruses, fungi, parasites and other pathogens that can invade the body caused by local tissue and systemic inflammatory reactions, commonly found in medical waste.
