Recycling rates vary widely globally with some developed countries achieving greater than 50%, however many countries have very low rates of recycling with the majority of waste still going to landfill. Interestingly, European countries with the highest penetration of Waste to Energy also have the highest recycling rates. Although Australia’s recycling rate at 52% (2006/07) is pretty good by world standards it has only slightly increased from 1999 levels. That’s because 91% of Australian households already recycle but there is a limit to what can be recycled.
