Hi readers.......
@mafzaal92 again on steemit with new informative post. Today i will talk about the waste menagment, In our world we use diffrent types of product these products are helpful for human. But if we can see other these these products contain some useful things. We cannot use things in our life and throw in open environment. waste change the our earth conditions and cause many diseases.
So today i will talk about the those methods that convert the waste into useful products. Many countries use these methods but some are not. There are five methods of protecting environment from waste contamination.

• Land fill
• Inciration
• Resource recovery
• Biologocal oxygen demand.
• pyralysis and gassification.

Land fill

Land fill is method of controlling and reduce quantity of waste material from our earth. In land filling process we fill the inorganic waste in the earth. Inorganic waste is that type of waste that cannot be broken down. This waste still in his original condition. In this first method we use non fertile land for the dumping of wastage.

Inciration

Inciration is process in which we burn the waste waste. This method is mostly used for peels and combustible waste.
Here are some steps that are doing in inciration process

• First of all we burn the waste
• After the burning of waste, heat is produced.
• We use this heat in manufacturing of steam from water.
• Through steam we run the turbines that produce electricity.
  

Resource recovery.

Resource recovery is process in which we use waste material through diffrent methods.

• Reuse
  in this method, we again use the waste material in same purpose. For example plastic bottle.
• Recylcling.
  In this method we recycle the our waste material and convert into same product. For example conversion of waste paper into useful paper.
• Conversion.
  Through conversion process we convert the waste material into other useful products. For example conversion of plastic bottles into bed matris.
  

Mechanical biological treatment.

Mechanical biological treatment is a method in which we convert the waste material into RDF oil. This oil is used in the construction of roads of large buildings.

paralysis & Gasification

paralysis and gasification are two related thermal treatment, through paralysis and gasification we convert waste into useful products.

• In paralysis process we convert the waste material into solid, liquid and gas.
• In gasification we convert the waste material into gas. Through gasification process we obtain syn gas.
