Waste disposal has changed dramatically in recent years. In the past all household waste was disposed of at landfill sites. This was the cheapest method, however, it was also the most ecologically damaging, creating methane gas. Some items, such as plastic would take thousands of years to decompose.
Household waste, that cannot be recycled, is delivered to the Mechanical Biological Treatment plant (MBT). This process takes everyday household waste and after processing produces a pellet like item that is used for generating power.
