What with all of these new and wonderful gadgets out this year, it's no surprise that some of your older tech might end up on the scrap heap.

But not 48.9 million tonnes of it.

That's the total weight of gadgets thrown away in 2012, as reported by a partnership of UN organisations and other industry figures, the Solving the E-Waste Problem Initiative (Step).

Electronic waste includes everything from phones and computers, to TVs, microwaves and fridges.

Step says that around the world the total amount of electronic waste was 11 times heavier than the Pyramid of Giza, or 200 Empire State Buildings.

And that number is still on the rise - Step's predictions say that more than 60 million tonnes will be thrown away by 2017.

To the current total the UK contributes about 1.3 million tonnes - unfortunately more than you'd expect based on our population alone.

According to a separate recent study, the value of the electronics discarded by British consumers works out to about £762 million a year. That study, by SquareTrade, said that more than 1.2 million Brits have received an electronic gift that they've never even taken out of the box.

China was the highest contributor with 11.1 million tonnes while the US - despite having about a third of China's population, was second with 10 million tonnes.

You can explore the full set of figures on this world map produced by Step.

  • Sony A7 System Camera

    For a relatively low cost, the Sony Alpha A7 blends the flexibility of an interchangeable lens system and a full-frame sensor with a small, compact size and a relatively low price of £1,299. It's a breakthrough device, and while it's not perfect - the battery life could use a boost - it's a remarkable re-think of how cameras are supposed to work.

  • Samsung F8000 46-Inch TV

    This is the best telly we've ever tested in person, with amazing picture quality and genuinely useful Smart TV features. It's an excellent screen on which to play the Xbox One, and its range of included catch-up apps plugs the gaps in the One's app line-up at launch. The only problem? The price - which is about £1,450 for the 46-inch model.

  • Sonos Play:1

    We're <a href="http://www.huffingtonpost.co.uk/2013/07/23/sonos-system-review-playbar_n_3639336.html">huge fans</a> of the Sonos system, which allows you to easily and wirelessly connect a range of speakers into a network around your home, and play a massive amount of content through a dedicated app. <a href="http://www.huffingtonpost.co.uk/2013/10/23/sonos-play-1-speaker-review_n_4148934.html" target="_blank">The Play:1s are among our favourite Sonos components yet</a> - small, neat, compact and with excellent sound quality. They're the gateway drug to the most complete audio solution in the world. (£<a href="http://www.sonos.com/shop/products/play1" target="_blank">169</a>)

  • iPhone 5S

    With the same ultra-clear Retina display as the iPhone 5, but a new <a href="http://www.huffingtonpost.co.uk/2013/09/10/iphone-5s-uk-pictures-release-date_n_3898775.html?1378818683&utm_hp_ref=uk-tech" target="_blank">fingerprint sensor</a>, a seriously impressive 64-bit A7 chip, an improved camera and a new gold design option, this is the best iPhone ever made. And with its consistent market-leading app selection, easy-to-use OS and delightful design, it's hard to argue against it being one of the very best gadgets ever made too.

  • Apple Macbook Air 13 Inch

    <a href="http://www.apple.com/uk/" target="_blank">A light but powerful compromise</a> between the heavier Macbook Pro and the iPad Air, the new 13-inch Macbook Air has an incredible 12-hour battery, an Intel Haswell chip and is just as light and portable as ever. A stunning machine.

  • Bose QuietComfort 20i

    These in-ear headphones are among the best we've ever tested - and you'd hope so, <a href="http://www.bose.co.uk/GB/en/home-and-personal-audio/headphones-and-headsets/acoustic-noise-cancelling-headphones/quietcomfort-20i-headphones/" target="_blank">because at £259 they aren't cheap</a>. What you get for your money is a combination of great, rich sound, brilliant noise-cancelling tech and the most comfortable fit you can find without involving a custom-made solution.

  • Xbox One

    The new Xbox One is a bold, unfinished but awesomely powerful statement of where Microsoft wants gaming to go. <a href="http://www.huffingtonpost.co.uk/2013/11/20/xbox-one-review-uk_n_4307600.html?utm_hp_ref=uk-tech">Check out our full review here</a>.

  • HTC One

    The HTC One is probably the most beautiful smartphone on the market - and is also the most intelligently designed. With twin, front-facing speakers it's the best choice for watching movies, and its 4MP 'Ultra Pixel' camera punches above its meagre pixel-count suggests.

  • Lenovo IdeaPad Yoga 13-inch

    <a href="http://www.laptopmag.com/review/laptops/lenovo-ideapad-yoga.aspx#review">Laptop Magazine said</a> "the IdeaPad Yoga is an able contortionist, blurring the line between laptop and tablet, while enabling users to explore the full capabilities of Windows 8". We agree. With a bright touchscreen, an 180-degree rotating display and an all-important sturdy hinge, it's a decent bridge between tablet and laptop.

  • iPad Mini With Retina Display

    At £319, the iPad Mini with Retina display isn't cheap. But on the other hand, it has the same screen resolution, processor and other internals as the larger iPad Air, while also being smaller, lighter and cheaper by £80. It's a stunning tablet, and though it's pricier than other 7-inch devices it's got the benefit of Apple's amazing apps selection.

  • PS4

    For £349, you can't buy a more powerful games machine anywhere in the world. Yes, it lacks games right now - but if it's been a few years since you gave FIFA, Assassin's Creed and Battlefield a go, there's more than enough to keep you busy until Destiny and Watch Dogs come out in 2014.

  • Kindle Fire HDX

    The new Kindle Fire HDX tablet comes in both a 7- and 8.9 inch version, and both are tasty upgrades. The 7-inch has a 1920 x 1200 display, a quad-core processor, LTE, all the Amazon services you'd expect plus a new 'Mayday' support service for new users. It starts at £199. The 8.9-inch is pricer at £329, but has an even more impressive 2560x1600 display - and still comes in lighter than an iPad Air.

  • Google Chromebook Pixel

    <a href="http://www.google.com/intl/en_uk/chrome/devices/chromebook-pixel/" target="_blank">Google's ChromeBook Pixel</a> has the best screen we've ever seen on a laptop - and features stunning hardware design. It only runs the browser-based Chrome OS, however, and as such is severely limited in what it can actually do. But for the right kind of user, it's a wonderful machine.

  • iPad Air

    The new iPad Air from Apple is an incredible new upgrade to the tablet you know and love. It's far lighter and thinner, has an upgraded processor, <a href="http://www.huffingtonpost.co.uk/2013/11/05/ipad-air-review-4g_n_4217913.html?utm_hp_ref=uk-tech" target="_blank">and in our review we called it nothing short of a "masterpiece"</a>. If you have more than £399 to spend on a tablet, spend it on this.

  • Cambridge Audio DacMagic XS

    For the audiophile in your life, the <a href="http://www.cambridgeaudio.com/products/dacmagic-xs-usb-dac-headphone-amp">Cambridge Audio DacMagic XS</a> is a brilliant little gadget, again for less than £100. The idea is simple - plug this into your USB port on your computer, plug your headphones in the other end, and experience sound quality you never thought possible from a laptop or desktop. The results are dramatic, and the product is cute and well designed, with specs worthy of competitors more than twice the price.

  • Nike Fuelband SE

    The Nike Fuelband is one of the most attractive and intuitive fitness trackers on the market - and 2013's new SE edition is the best one yet, adding Bluetooth LE for constant syncing with your iPhone, 'Session' markers and limited sleep tracking. It's not a complex gadget, and it's hurt by the lack of Android compatibility. <a href="http://www.huffingtonpost.co.uk/2012/06/20/nike-fuel-band-review-the_n_1612388.html" target="_blank">But it works, is stylish and has earned a legion of fans.</a>

  • Samsung Galaxy Note III

    The Note III is huge, but it's beautiful and for the right user one of the very best devices on the market. It's got a 5.7-inch screen, though with the same 1080P resolution as the Note II, while adding a Snapdragon 8000 quad-core processor, some new software enhancements and a few new S-Pen functions into the mix. If you're looking for a giant note-taking phone, this is still your best bet.

  • Microsoft Surface Pro 2

    Microsoft's new Surface Pro runs a full version of Windows 8.1, has an improved kickstand and an excellent display and can do pretty much everything your tablet AND your laptop can do. You're going to pay for it - the device is £719 and up, plus the great keyboard cover is not included in the price. It's also heavy and there's no LTE option. But it's a lovely piece of kit for the right user.

  • Olloclip 4-in-one Lens

    <a href="http://www.olloclip.com/">The Olloclip</a> is a brilliant little device which connects to your iPhone in seconds, and gives you access to four new lenses which change the type of picture you can take, without altering the quality. You can get a fish-eye, wide-angle, macro-10x and macro-15x lens in the one little unit. And at £59.95, it won't cost anywhere near what a stand-alone camera capable of the same pictures would cost.

  • Bowers And Wilkins A5

    This £399 speaker is straightforwardly beautiful, with brilliant sound and easy iTunes syncing.
