A paper shredder, also known as a shredder, shreds paper so you can no longer read the text. There are different classes according to the DIN norm. The higher the DIN P-value, the smaller the shreds. If you want to meet the GDPR norm, choose a shredder with at least a P-4 level. You can manually destroy the paper or get a shredder that automatically shreds a pile of paper. There are also paper shredders without a cooling down period. With those, you can shred paper without having to wait in between.
