Why Recycle Your Laptop

How to dispose old laptops, phones securely in Singapore

Recycling your laptop is important because if it ends up in a landfill, the problem isnt solved it only begins. Electronics that end up in the trash can become a serious environmental and health hazard.Electronic devices contain toxic materials like chromium, flame retardants, and lead. These materials have been related to damage to kidneys, blood, and the central nervous system.

Findings from most studies showed increases in spontaneous abortions, stillbirths, and premature births, and reduced birthweights and birth lengths associated with exposure to e-waste.

When you throw your electronic notebook with the household trash, those toxic materials can leak into landfills and even reach groundwater or vaporize into the air in landfill fires. Yet, apart from recycling responsibly, there is another way people can help reduce the amount of electronic waste. After recycling your old computer, instead of ordering a brand new machine, get a refurbished one. Not only will you pay much less, but youll help reduce demand for raw materials. Also, it feels great to salvage a perfectly working computer from being dismantled for scrap.eBay is a great place to look for refurbished laptops. In fact, GreenCitizen has our own eBay store, where you can find the latest line up of refurbished laptops that work like new.

Destroying A Hard Drive With A Hammer

This is the fastest and most effective method of physically destroy a hard drive. A user just needs to take a hammer in his hand and start hitting a hard drive with it. Moreover, one should be alone in a room while performing this task to avoid any accident with flying pieces of metal and glasses. Once it is break in pieces completely, collect and dispose them carefully.

How To Dispose Of Computers Spoil The Hard Disk

Imagine you need to dispose of some important paper files that you no longer need. What are your options? You can burn it . A better option is to shred it so that the contents are not comprehensible anymore. You can do the same thing with your files on the hard disk. You should not burn it, and I wont recommend you do that but sure, many prefer to physically dent the hard disk drive with a hammer! You also dont need to wipe SSDs because of TRIM.

You sure can shred the files using some software. Anti Tracks, CCleaner and Comodo System Cleaner are some programs that shred files one at a time. You can use them to shred particular files. KillDisk and DP Wiper are disk wipers in the sense that they shred all the files on a hard disk in one or more passes. The major difference is that you need not to select each file separately.

Sanitizing To Prevent Data Discovery

No matter how much you try to protect your mobile devices there are tools readily available to extract the viable information from them if the attacker has the time and resources to do so. With this as the case, how do you really know if your PII will even be safe if it falls into the wrong hands? There are currently only three approved methods for device sanitation, wiping, degaussing and destruction. NIST Publication 800-88 outlines these three methods for sanitation that will effectively eliminate the recovery of data from a device even through a laboratory attack.


While a full wipe truly changes the layer of data it is only as effective as the number of times the hard drive has been wiped clean, re-written and then wiped again. It is typically done a minimum of three times but realistically it will need to run through at least 15 cycles of wiping and rewriting before it is truly unrecoverable. Three popular and free software available for data destruction include:

  • DBAN Dariks Boot and Nuke
  • Disk Wipe
  • Secure Erase
  • Before trading in or disposing of your device, test to make sure that the wipe was successful by trying to access your media through your device. Also note that if the wipe has not gone through enough cycles then it can still leave your device open to criminals utilizing carving methods for data extraction.



    DISCLAIMER:this method is also extremely fun!

    When Pii Becomes A Problem

    Broken Laptop Disposal Guide

    People store their PII onto their devices in order to make it more accessible. However, the premise of making such private data easy for the individual to find also makes it easy for the criminal to find, even if it is deleted. People often forget what they dont see, which is why when data is seemingly deleted from a device and becomes invisible to an untrained eye the person thinks it truly is gone. In reality though, deleting data doesnt mean its really gone it just means its hidden from the average Joe.

    Tech savvy criminals understand this common train of human thought and they know how to uncover the unseen value in abandoned devices. Just as criminals breach organizations such as TJ Maxx and Citibank, put skimming devices on ATMs or steal your wallet when you turn a blind eye, picking up a discarded device can hold mounds of financial gain to the properly trained individual. All the information listed above can paint a detailed picture of a persons life from their physical health to their banking preferences, making the possibilities for executing a complete takeover of a persons identity endless.

This may increase the rate at which we dispose of computer equipment — and it can increase the expose us to security threats if we aren’t careful about how we do it. Take the following list of tips for secure equipment disposal to heart.

    How To Wipe A Computer Before Recycling It

    Before you wipe anything, you should make sure to save any important data on a backup drive. External hard drives, USB jump drives, or even cloud storage will work, but you can always port it over to your new computer too. Thankfully, most modern computers make this fairly easy its a lot of cutting and pasting, or sliding files into folders.

    To wipe the computer, you need to delete all the data that remains on the hard drive. This is not as simple as dragging all files to the recycle bin and deleting cookies, however, as several data recovery programs exist that can retrieve deleted data. Many can be found here.

    The first step in this process is to manually delete files from the system. Shredding programs like File Shredder can overwrite the files and clean up the drive. It is recommended that files are shredded and overwritten several times to make them harder to retrieve. Data can be found on several drives within the machine, so each drive must be prepared in a different way.

    Once you have completed the sometimes lengthy process of moving, deleting, and shredding your files, the next step is to format the computer. This means you restore the computer to factory settings. The process for doing this is different for a Windows PC, a Mac, and a Chromebook, of course, but all have fairly easy steps, even if you’re a novice.

    Securely Dispose Of Your Laptop And Its Parts

    Even when you rule out any possible harm related to your data, there are still some aspects for you to take care of before you can part ways with your laptop. The machines contain toxic and dangerous substances such as arsenic, mercury, and lead therefore, it is not environmentally safe to dispose of your computer by just throwing it in a bin.

    Among the most valid alternatives, to dispose of your laptop securely, you should:

  • Recycle it or remarket it: recoup a sum of money for the parts of your computer that still have value. Some companies offer IT remarketing services to recover a part of the cost you sustain. The money you gain can add up when you dispose of machines in bulk, allowing your business to mitigate the costs of replacing the old devices.
  • Resell it: if your laptop is in good condition and youre sure behind doubt that the hard drive has no data on it, theres no reason why you should not be able to recoup part of what you spend on a new device by selling your computer.
  • Donate it: if your laptop is not suitable for you but still running, you could donate it. Firstly, you would do the environment a favour, as 70% of a computers lifetime footprint is related to the manufacturing process, therefore extending your devices lifetime can reduce the overall impact on the ecosystem. Donating your laptop would also get one more device in the hands of people who cant afford it, helping to narrow down the digital divide.
