In many countries, large corporations dump their waste in places they shouldn’t. Instead of throwing their trash away properly, they get rid of it in locations that don’t have strong environmental laws.
However, that’s not the case in Finland, at least as far as nuclear waste is concerned.
In 1994, a change was made to the Finnish Nuclear Energy Act requiring all of the nation’s nuclear waste to be disposed of inside the country.
Just one problem: Finland didn’t have a storage facility to hold all of that waste.
To resolve this, the country began building a massive underground storage bunker on the small island of Olkiluoto. Between 2004 and 2011, the location for the facility was excavated, with plans to begin constructing the building itself in 2015.
The bunker will accept waste until 2120, at which point it will be sealed off. Current projections show the bunker lasting until the year 102,120, meaning it will probably be one of humanity’s last relics on Earth.
