This year, 5.3 cardinal mobile phones volition beryllium thrown distant not recycled, the planetary discarded electrical and physics instrumentality (WEEE) forum says.
Its estimate, based connected planetary commercialized data, highlights the increasing biology occupation of "e-waste".
Many radical support aged phones, alternatively than recycling them, probe suggests.
Precious minerals not extracted from discarded electronics, specified arsenic the copper successful ligament oregon the cobalt successful rechargeable batteries, person to beryllium mined.
"People thin not to realise that each these seemingly insignificant items person a batch of worth and unneurotic astatine a planetary level correspond monolithic volumes," WEEE manager wide Pascal Leroy said.
There are an estimated 16 cardinal mobile phones worldwide - and successful Europe, astir a 3rd are nary longer successful use.
The WEEE says its probe shows the "mountain" of electrical and physics discarded - from washing machines and toasters to tablet computers and planetary positioning strategy (GPS) devices - volition beryllium increasing by 74 cardinal tonnes a twelvemonth by 2030.
Earlier this year, the Royal Society of Chemistry launched a run promoting the mining of e-waste to nutrient caller products, highlighting planetary conflict, including the warfare successful Ukraine, threatens precious-metal proviso chains.
Magdalena Charytanowicz, of the WEEE, said: "These devices connection galore important resources that tin beryllium utilized successful the accumulation of caller physics devices oregon different equipment, specified arsenic upwind turbines, electrical car batteries oregon star panels - each important for the green, integer modulation to low-carbon societies."
It highlights it is 1 of the "fastest increasing and astir analyzable discarded streams that affects some quality wellness and the environment, arsenic it tin incorporate harmful substances".
In the UK, much than cardinal unused but moving electrical items, worthy arsenic overmuch arsenic imaginable £5.63 billion, are presently hoarded successful UK homes, surveys by the organisation Material Focus suggest.
It besides calculated that the mean UK household could merchantability unwanted tech and rise astir £200.
The organisation's online run provides tips, including wherever to find recycling centres.
Mr Leroy said overmuch much could beryllium done.
"Providing postulation boxes successful supermarkets, pick-up of tiny breached appliances upon transportation of caller ones and offering PO [post-office] boxes to instrumentality tiny e-waste are conscionable immoderate of the initiatives introduced to promote the instrumentality of these items," helium said.
