What are the methods of human waste treatment?
Methods of processing depend on the type of human waste: The amount of water mixed with human waste can be reduced by the use of waterless urinals and composting toilets and by recycling greywater. The most common method of human waste treatment in rural areas where municipal sewage systems are unavailable is the use of septic tank systems.

The most common composting techniques include static pile composting, vermin-composting, windrow composting and in-vessel composting.
Why are landfills important?
Sanitary landfills provide the most commonly used waste disposal solution. These landfills are desired to eliminate or reduce the risk of environmental or public health hazards due to waste disposal. These sites are situated where land features work as natural buffers between the environment and the landfill.
How does pyrolysis reduce waste?
It quickly reduces waste volume, lessens transportation costs and decreases harmful greenhouse gas emissions. Gasification and Pyrolysis are two similar methods, both of which decompose organic waste materials by exposing waste to low amounts of oxygen and very high temperature.
What is a bioreactor landfill?
Bioreactor landfills are the result of recent technological research. These landfills use superior microbiological processes to speed up waste decomposition. The controlling feature is the continuous addition of liquid to sustain optimal moisture for microbial digestion.

What is incineration in waste?
Incineration, as a conventional waste treatment method, is based on thermal processing result in heat production and combustion products such as gases and ash. The process involves a complete oxidation at 870–1200°C and produces carbon dioxide and water as gaseous products together with small amount of carbon monoxide, nitrogen oxides, and some other organic or inorganic compounds. Incineration can be carried out near the field of waste collection and methane formation does not occur during the process unlike landfill. In addition, it is one of the best options for hazardous wastes to get a sterile ash product (Arvanitoyannis et al., 2008, p. 353 ). As incineration has a low efficiency in energy utilization, the generated heat can be used in steam turbines and heat exchangers in the industry. Despite having the described benefits, incineration is a suitable application when the water content of the waste is relatively low. Since food wastes generally have a high moisture content and contain combustible compounds, incineration is not always practicable for waste treatment in food industry. Furthermore, emissions are also an issue to be considered as well as hazardous pollutants (TSP and dioxins) ( Digman & Kim, 2008 ).
What is thermal treatment?
Thermal treatment of waste is accompanied by the release of a considerable amount of heat that depends on the heat value of the waste being processed. An important task of process-technology design is to utilise efficiently the heat value of the products of incineration and, in this way, partially compensate for the costs of waste thermal treatment. Possible methods of heat utilisation are:
Is eutrophication potential different between treatments?
To a lesser degree, the estimation of eutrophication potential for other treatment techniques can also be quite different between studies. This could be a result of the variation of practicing the treatment in detail or the assumptions applied in the study for calculating the eutrophication potential.

Why Treat Wastewater?
It's a matter of caring for our environment and for our own health. There are a lot of good reasons why keeping our water clean is an important priority:
Wastewater treatment
The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
What is hazardous waste?
Simply defined, a hazardous waste is a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment.
