However, you may be wondering what actually happens to your hazardous waste once it has been collected. Hazardous waste is disposed of in a variety of ways; thermal, chemical, biological, and physical. In this blog, the expert team at Willshee’s talk you through how each method works.
Chemical waste disposal
Chemical methods include precipitation, oxidation and reduction, ion exchange, and neutralisation. Chemical methods, as well as thermal and biological methods, all work by changing the molecular form of the waste material.
Thermal waste disposal
Thermal disposal of hazardous waste is usually done by incineration. The incineration must be conducted at an extremely high temperature and can be used to both detoxify and destroy waste depending on type. Special thermal equipment such as fluidised incinerators, multiple-hearth furnaces and rotary kilns are used to burn the waste, which can be in solid, liquid, or slush form. However, one of negative to the incineration of hazardous-waste is that it contributes to air pollution.
Biological treatment is another form of hazardous waste disposal which is suitable for many organic waste types, such as those from the fuel industry. The most-common biological treatment of hazardous waste is landfarming. In landfarming waste is mixed with soil in a designated area of land before special microbes are added. These microbes help with the metabolisation of the waste. Nutrients are sometimes also added, as well as a genetically engineered type of bacteria designed to assist with the process.
Physical treatments differ from these methods as they concentrate, solidify, or reduce the volume of the waste, rather than altering its molecular form. Physical disposal methods range from evaporation and sedimentation to flotation and filtration.
Solidification is one example of a physical method of hazardous waste disposal. This method works by containing the waste in concrete, plastic or asphalt. The encapsulation process results in a solid material which prevents leaching. The waste material can also be mixed with lime, pulverised fuel ash and water to form a product similar to the texture of cement.
