Mine your phone – (smart)phone collection

We have to admit it, we all have a broken or unused (smart)phone lying somewhere in the corner of a drawer. What about donating it to a good cause? You are getting rid of your rubbish, we are using it for a good and sustainable cause. That’s a win-win! The Green Office is proud to announce the ‘Mine Your Phone’ project together with Recupel vzw and Out Of Use.

We will plant a tree for every working phone and every 4 non-working phones we collect. Out Of Use will finance this through donations for Natuurpunt vzw.


You can donate your (smart)phone in collection boxes located at several libraries throughout Leuven. We will also organize some e-waste related activities where you can donate your phone. Make sure to stay up to date with us if you don’t want to miss out! There will be a box in the following locations from 11/3 until 24/3

These phones will be processed by companies working on the topic of metal recovery. After the collection, Out Of Use will test them to see which devices can be reused. The non-reusable devices will then go to Umicore, where the final processing happens and valuable elements can be recovered.

Note: By law those companies are obligated to remove ALL data on the phones they deem ‘reusable’. Our partners guarantee that your data will be safely removed.
