New trends have emerged in the cleaning up of hazardous waste. Conventional methods have become obsolete, and new waste management and disposal methods have taken over. These new age methods are very effective in hazardous waste disposal. They make short work of the lump and boast of a proven track record in disposal of hazardous waste. Their efficacy has persuaded the authorities to make them a permanent fixture. No more are they trial maneuvers, but fixed ones that get used all the time. Some of them have been given below:
Integrated Waste Management: This method is a recent find and done through life cycle analysis. This is put to use during the disposal of hazardous waste from municipal sites. Segregation, source separation and collection followed by re usage and recycling, comprise of this method. After this stage, comes fertilizer production from the organic waste fraction. Non metallic water resources are retained and not destroyed, to get eventually reused.
Plasma Gasification: Plasma is known to be an electrically charged and ionized gas. Lightning too has Plasma, where unsurprisingly the temperature goes in excess of 7000 Degree Celsius. The Vessel, in which the Gasification process takes place, touches an operating temperature of around 5500 Degree Celsius. This creates a highly intense gasification zone where solid gets converted into liquid, and eventually into Gas. This process subsequently leads to elemental destruction of these hazardous materials, leading to success hazardous waste disposal.
Landfill: Disposal of hazardous waste in a landfill involves burying the waste. Landfills are mostly fixed in deserted pits and mining voids. The landfill has an innate ability to be hygienic and inexpensive at the same time. The characteristics of a well designed landfill include containing feces, keeping vermin and rats at bay and having gas extraction systems or extracting landfill gas. The extraction process happens through perforated pipes and the gas extracted is burned off in gas engines to generate electricity. Disposal of hazardous waste happens in style.
Incineration: This method of hazardous waste disposal involves combustion of waste material. Incinerators, in which this process happens, convert waste materials into heat, gas, steam or ash. The finest benefit coming from this method is that while the incinerators are working, a lot of heat is produced which eventually get used as energy.
Recycling: Recycling is a semi conventional method of disposal of hazardous waste. The process involves the conversion of such hazardous waste into remodeled and useful products. The material is sorted directly from mixed waste.
These are some of the latest techniques used for the disposal of hazardous waste. The techniques are some of the finest ones to be put into place so that the waste is taken care of. They are vey different from the typical conventional methods and some of them in fact, have not even been heard of till recently. Using them can be very useful in the disposal of such waste as they take care of every flaw that was prevalent during the days of yore when things were done conventionally.
