More electronic waste than ever hit the rubbish tips last year, with the biggest per-capita tallies in countries that pride themselves on environmental consciousness.

Last year, 41.8 million tonnes of so-called e-waste – mostly fridges, washing machines and other domestic appliances at the end of their life – was dumped, a UN report said.

That’s the equivalent of 1.15 million heavy trucks, forming a line 23,000km long, according to the report, compiled by the United Nations University, the UN’s educational and research branch.

Less than one-sixth of all e-waste was properly recycled.

In 2013, the e-waste total was 39.8 million tonnes – and on present trends, the 50-million-tonne mark could be reached in 2018.

Topping the list for per-capita waste last year was Norway, with 28.4kg per inhabitant.

In volume terms, the most waste was generated in the US and China, which together accounted for 32 per cent of the world’s total, followed by Japan, Germany and India.

Waste that could have been recovered and recycled was worth US$52 billion, including 300 tonnes of gold – equal to 11 per cent of the world’s gold production in 2013.
