An electronic one game for every person on Earth – that's the staggering number of electric trains, drones, talking dolls, R/C cars and other kid gadgets that end up in landfills every year.
The devices we recognize as e-waste are usually computers, smartphones, televisions and sound systems. But there are also "non-traditional" waste such as electronic tools, vaporizers, LED accessories, USB cables, or anything related to rechargeable lithium batteries. 
In total, people around the world fly about 9 billionmillions kilos of e-waste that are usually not recognized as such by consumers.
This "invisible e-waste" is the focus of the sixth annual World E-Waste Day on October 14, organized by the forum Waste Electrical and Electronic Equipment (WEEE).
In anticipation of the event, the agency recently commissioned the United Nations Institute for Training and Research (UNITAR from the United Nations Institute for Training and Research) to investigate how much unusual e-waste is discarded each year.
According to UNITAR's findings, the total weight of all electronic vapor cigarettes thrown away each year is roughly equivalent to 6 Eiffel Towers.
Meanwhile, the total weight of all invisible e-waste amounts to "nearly half a million 40-metric-ton trucks," enough to create a bumper-to-bumper line of vehicles stretching roughly 3.504 miles, or the distance between Rome and Nairobi .
From a purely financial standpoint, nearly $10 billion in basic raw materials are literally thrown away every year.
