You may think that sending waste to landfill means it is simply dumped in a pile of waste that is left to rot. However, there is a little more to it than that. Modern landfill sites are closely engineered and managed to ensure they do not cause pollution to land, air or waterways.
Landfill sites are closely monitored for around 50 years after they stop accepting waste to ensure they remain safe.
When waste arrives at a landfill site, it is compacted and covered in materials, such as soil, that help to reduce odours and vermin. Gas is also collected and used to generate energy that is transferred to the National Grid and the leachate (think bin juice but on a major scale) is treated and returned to the water course when it is safe.
The trouble with landfill is that it does still produce large quantities of methane and other dangerous greenhouse gases. It also costs councils a lot of money to send rubbish to landfill sites, so we should all be doing our bit to keep our waste out of landfill wherever possible.
