23 January 2026

The Kierrätyskeskus loyalty customer discount rate is changing. Starting from the beginning of March, loyalty customers will receive a 5% discount on purchases included in the loyalty programme. For students, the new discount rate will be 15%. The change is driven by financial reasons, above all a significant decrease in public funding.

The reform will also introduce several loyalty days each year, during which loyalty customers will receive special product‑category‑specific discounts. In other words, even bigger discount bursts are on the way, helping an ever‑growing amount of items find a new life 💚

The loyalty card itself will also be renewed, but we will share more details about this a little later.

19 December 2025

The renewal of the Kierrätyskeskus loyalty programme will begin at the turn of the year. The first phase involves changes to the system itself and does not require any action from current loyalty customers.

We will share more information about upcoming changes as they become relevant.

If you encounter any issues, you can contact loyalty customer support: asiakastuki@kierratyskeskus.fi
