What do you get in exchange for your old phones?

An old smartphone or cell phone contains more precious metals per gram than many types of ore found in mines. Gold, silver, palladium, and copper in the circuit board, lithium-ion in the battery, and aluminum in the casing make phones attractive for recycling. We pay based on weight and type: smartphones fetch a higher price than old push-button phones because their circuit boards are more advanced. For larger batches—such as those resulting from a company’s fleet replacement—we provide a customized quote in advance. Working devices suitable for refurbishment can be evaluated separately.

More about trading in phones

Recycling old cell phones is crucial for both the environment and the economy. Old devices contain valuable materials such as gold, silver, and copper, which can be reused in new products. This reduces the need to extract new raw materials, which often places a heavy burden on nature. In addition, phones contain harmful substances, such as lithium and cadmium, which can seriously pollute the environment if not processed properly. By turning in your old phone to Krommenhoek Metals, you’re contributing to a cleaner world and helping to prevent the waste of raw materials. Turning in and recycling your old phone isn’t just good for the environment—it’s also an important step toward a circular economy.

Reliable and Secure Shredding

All phones contain a battery, almost always a lithium-ion battery. It is very important to handle devices containing batteries properly, due to the potential fire hazard. If a lithium battery is damaged, there is a risk of spontaneous combustion. It is therefore strongly discouraged to hit phones with a hammer, fold them in half, or punch holes in them. Unfortunately, we still see this happen regularly.

Krommenhoek Metals is fully certified and an expert in recycling old cell phones. We hold current certifications and have also earned the rigorous WEEELABEX certification for Collection & Logistics. This ensures the highest quality recycling and the lowest possible environmental impact. Choose Krommenhoek Metals if you want to turn in and recycle your old phones.

Excellent service is our top priority

We believe it’s important to help our customers as best we can, which is why we do everything we can to ensure everyone has a positive experience. Our experienced, knowledgeable, and certified staff are happy to advise you and answer all your questions about trading in old phones. We promise to offer you a good price for your old electronics and are happy to accommodate you if you’re bringing in larger quantities to our drop-off locations.

Returning old phones to Krommenhoek Metals is quick and easy. You can stop by one of our locations during our extended hours. Our experts will immediately sort and appraise your materials. We use a transparent pricing system. After the appraisal, you can choose to receive immediate payment via bank transfer, cash, or Tikkie.

In the Netherlands, electronics recyclers are certified under the WEEELABEX certificate. When you have your old phone recycled by a certified company, you can be sure that it will be done professionally. Krommenhoek Metals holds this certification for Collection & Logistics. This ensures that all parties we use to process electronics meet the high standards set by WEEELABEX/CENELEC.

For example, with cell phones, it is mandatory to remove the battery and screen first. If this is not done, harmful substances can be released into the environment. Furthermore, there is a risk of fire.

At KH Metals, you can not only drop off old phones, but also have all kinds of other electronic devices recycled responsibly. This includes dropping off old laptops, computers, and circuit boards, as well as having hard drives securely destroyed.

By using our electronics recycling service, you’re helping to create a more sustainable environment and ensuring that your data is processed securely.

Trade in old phones

Old phones are worth money and are also full of data—both personal and business-related. So never just throw old phones away. Bring your old phones to Krommenhoek to get paid for them. That way, you can be sure the old phones will be processed properly. We pay per kilogram for various types of phones. If you have a large batch of (business) phones, we can also buy them from you.

We’re able to erase all data from phones using certified software. Never try to destroy a phone with a hammer or drill. This can cause the battery to spontaneously catch fire!

Turn in a large batch of old phones

Do you want to turn in a significant number of old phones, and are they in working condition? If so, destroying or recycling them is often a waste. Choose the most environmentally friendly and cost-effective option: have Krommenhoek buy your old phones. Depending on the type of phone, we can offer a price per unit. We’ll then handle certified data wiping. The entire process is documented, and afterward, you’ll receive a clear and comprehensive (data) destruction certificate from us.

Here's how to safely turn in your old phones

For most individuals, turning in a handful of old phones is as simple as stopping by our location in Rotterdam or Wateringen. We weigh them, assess their condition, and pay you on the spot. Send us a photo via WhatsApp in advance if you’d like a price estimate.

Data security is a top priority for businesses. Upon request, we remove the SIM cards and SD cards, and the devices undergo a data wipe or physical destruction of the memory, depending on your policy. For ITAD processes, we provide a Certificate of Destruction with serial numbers and a chain-of-custody report. The entire process is WEEELABEX-certified, so you can be sure that the phones and their associated data have been properly processed.
