Bores are drilled down into the rubbish, and piped up methane gas to test for quality and quantity.If it's enough and pure it can be collected and used.If not it will be flared off.Auckland landfills should produce enough electricity for nine thousand homes.(The concentration of methane gas does not exceed __25%__ of the landfill gas)**
 * Landfill is a big hole dug into ground that put rubbish in it .When it fills up the machines will squashed down to put more rubbish.When the landfill used up, they will put soil on it to make it into parks etc.But when the rubbish rots it produce methane gas. This kind of gas can be dangerous and the chemical formula is known as __(CH4)__It is the simplest alkane, and the principal component of natural gas.The gas can __easily burn__ and it can explode, also it is one of the __strongest green house gases__. There is two main ways to dealing the methane gas are to burn it off called "flaring" or to used it as a fuel.

Methane gas:(Melting Point)：-182.5° C (-296.5° F) Boiling Point： -161.5°C**

// The Four "Rs" //

 * There are four main ways to reduce the amount of rubbish that ends up in landfill sites.They are some times called "the four Rs"**

> I refuse plastic bags because it can pollute the earth.**
 * **Refuse:To ignore someone that want to do something.

> I am trying to reduce my rubbish as much as I can for my science fair.**
 * **Reduce: Using less of things that will throw away.

> Cloth bags can be washed and reuse again and again and better than plastic bags.**
 * **Reuse:Use things more than once.


 * **Recycle:Torn old things that will throw away into new things that can used again.**
 * We can recycle plastic bottles, paper and glass to reduce the rubbish we have.**
