Abstract
Disposal of hazardous wastes requires proper waste management strategies due to the issues
related to pollution. Even though the recycling and reusing of the hazardous wastes is not always
the best strategy, there is always the needs for the treatment options for the hazardous wastes
before they are disposed. The hazardous materials are treated through the physical, biological,
thermal, chemical methods. The hazardous wastes that are disposed in land include wide ranging
substances, such as solvents and paints, radioactive wastes, ammunition, cadmium, nickel or
lithium batteries, appliances containing refrigerant, cleaning agents, propane cylinders and
aerosol cylinders, electronics, mercury containing wastes, pesticides, automotive wastes. The
alternative strategies that are found to be beneficial for the wastes disposal are: The onsite
containment process refers to the method in which the chemical or biological composition or
character of the hazardous waste materials are altered in order to neutralize the waste materials
or make it safer to dispose, transport or store without any harmful effect. The process of online
destruction is another possible strategy that could help to reduce the hazardous land disposal.
Such way of eliminating the hazardous waste materials sometimes termed as pyrolysis as high
temperature is used in the process of destruction. Incineration is another waste treatment
technique which is associated with the combustion of organic compounds present in the
hazardous waste materials. The process of incineration is also described as the high temperature
waste treatment or thermal treatment as well. Recycle is another effective process that could help
to reduce the amount of hazardous waste materials and its disposal in land.

Introduction
Hazardous waste can be described as the waste exhibiting properties that can potentially
harm and human health and environment. The hazardous waste is generated from several sources
that ranges from the manufacturing processes, industrial activities, wastes from the batteries and
the hazardous can be in different form including sludges, solid gases and liquids. Hazardous
wastes are disposed of mainly in the landfills (Higgins, 2017). Thus, it is important to mention
that disposal of hazardous wastes requires proper waste management strategies due to the issues
related to pollution. Even though the recycling and reusing of the hazardous wastes is not always
the best strategy, there is always the needs for the treatment options for the hazardous wastes
before they are disposed. The hazardous materials are treated through the physical, biological,
thermal, chemical methods. The various type of pollution that can affect from the land disposal
of the hazardous waste ranges from the air pollution, water pollution to land pollution (De Feo &
De Gisi, 2014). Hazardous wastes cause damage to the environment through several ways as it
has both the long term and he short term effects. The short term effects include the water
pollution. The hazardous wastes that are poured into the aquifers, lakes, rivers and streams
render the agricultural purpose and drinking unsafe. The long term effect of the environment
includes the destruction of the natural resources, trash into the green spaces, waterways, disease
in the humans, cancer in humans and mutation in animals (Jiao, Qi & Yanmei, 2013). This study
is based on the land disposal of the hazardous wastes and the various environmental pollution it
causes, the alternative strategies for mitigating the hazardous waste disposal, the policies in
relation to the land disposal of the hazardous wastes internationally and in Australia.
