Spain is planning to introduce a system where you return bottles and cans in exchange for money (called SDDR: Deposit Return System).
You pay a small deposit (around €0.10) when you buy a drink You return the empty bottle or can You get your money back
Basically, it’s the same idea as the old “returnable bottle” system, but it’s a complex system (machines, logistics, retailers…)
Some experts believe it could be delayed until 2027–2028
